American Zinnia During the sweltering summer months, combine blossoms in vivid hues of orange, purple, red, white, and yellow. This mixture is ideal for cut flower growers because it has large 45 flowers on sturdy stems. It gives a rainbow of colors to any planting and is very simple to grow.
grows naturally in Mexico and works best when sown directly. thin to 612 distances. To extend the flowering season, deadhead spent blooms and allow them to seed so that they will come back as volunteers the following year.
- Zinnias make wonderful cut flowers and are a major draw for butterflies and other beneficial insects to the garden. They thrive in Zones 9 and 10 from spring through late summer; if content, they might even bloom deep into the winter!
- grown only once a year. Four weeks before the final frost, start seeds indoors. If the weather is chilly, a heating mat will assist in achieving equal germination. After the threat of frost has passed, transplant outside.
- Small and flat, zinnia seeds are round. They ought to be planted not far below the soil’s surface. Start seeds in a high-quality seed starting mix if you’re starting them indoors in trays or starter pots. Cover the seed with 1/4 of the finely sifted dirt after scattering it over the thoroughly saturated soil. In 3–10+ days, seeds will begin to sprout.
- If you want to direct-sow the seeds, make sure the soil is thoroughly worked and free of debris by using a fine rake. Add 1/4 of well-sifted soil on top.
- This traditional annual bloom thrives in a variety of gardens, including ones with wildflowers and vegetables. It provides a superior cut flower and is simple to grow. In addition to growing zinnias for cut flowers, we do it to attract beneficial pollinators to the farm.
- Make sure your container is at least 10 deep if you are growing zinnia in containers. Since zinnias can grow big, we do not advise growing more than one plant per container. The plant will become unhappy from overcrowding and produce fewer blooms. More blooms will grow in the larger the container. Remember that because they have more surface area and less soil to absorb moisture, containers will dry out more quickly.
- Brightly hued zinnia blossoms provide happiness to the yard and are excellent cut flowers as well. For the longest-lasting blooms, gather flowers in the early morning and place them right away in a vase of room temperature water.
- Zinnias thrive from early spring through late October in Zones 9 and 10.
- AVOID overheading water because it encourages sickness.
- To ensure amble blossoms, side dress with an organic granular fertilizer.
- To promote additional blooms, deadhead wasted blooms.
- Together with other vibrantly colored flowers, zinnias thrive. They look great planted in front of our hollyhocks, sunflowers, and other tall blooming flowers. Buy all of our flowers right here. To aid in attracting pollinators to the garden, we also plant zinnia alongside the squash and pumpkin.
Can you cultivate zinnias in Southern California?
Can you recommend an annual bedding plant that is quick to grow from nursery packets, easy to grow, and can provide me with a lot of color throughout the summer heat?
A. The zinnia, in my opinion, would work nicely for you. There are a wide variety of zinnia flower varieties, sizes, and colors available. The height of some types ranges from under a foot to over two feet, and everything in between.
You can choose from blossoms that are less than 2 inches across to 5 inches across and are appropriate for cutting. Flowers are available in single colors or bicolors. The plants cover themselves in vivid, multicolored blossoms regardless of size.
You must give your garden proper care if you want to be sure that your plants are growing and blooming at their best. Regularly water and fertilize your plants, but don’t overdo it. Also, remove wasted blossoms as soon as possible to stop seeds from sprouting. Avoid getting the leaves wet, especially late in the day, as some zinnia cultivars are prone to mildew.
The nicest part about zinnias is that they don’t draw insects, and they survive full sun and hot temperatures quite well. The large and manageable zinnia seeds are ideal if you’re not in a rush. Zinnia seeds that are directly sown in the garden germinate fairly quickly in our temperate Southern California climate. Growing plants from seed is a quick and affordable approach to get lots of plants for a low cost.
Q. All the flowers in my border are being destroyed by earwigs. Even some of the roses I cut have earwigs living inside of them. What can I do to control them?
A. Earwigs are long, slender, brown insects with two posterior pincers that measure about an inch in length. Although they are typically not a problematic pest in the garden, if their population increases significantly, they can do significant harm by eating holes in leaves and blossoms.
They spend the day hiding in damp, dark locations and emerge to feed at night. This layout makes it possible to frequently regulate them by scattering loosely wrapped newspapers throughout the garden. The newspaper, which can be thrown out every day or two, will become home to the earwigs.
What month should zinnia seeds be sown?
Light: Full sun is ideal for zinnia growth and flowering. Even in warmer climates with afternoon shadow, they can flower there, but they may be more prone to disease and produce fewer flowers.
Soil: Organically rich, fertile soils with good drainage are ideal for growing zinnias. Because zinnia seedlings are susceptible to rotting in cool, damp soils, having well-drained soil is crucial.
Plant zinnia seeds in rows or clusters spaced a few inches apart. Once the plant has four leaves, thin to 8 to 18 inches apart, depending on the variety.
Planting: Plant zinnias in the spring, just about the time you plant tomatoes, when all threat of frost has passed. Growing zinnias from seeds straight in the garden is simple. Start seeds inside four to six weeks before to your last frost date for earlier flowering.
How is zinnia grown in California?
Direct sow in the spring; warm soil is optimum for the germination of this California Giant zinnia flower seed mixture. Plant barely below the surface and maintain a mild moisture level in the soil until germination, which normally happens in 7 to 10 days. Plants from seed do not transplant well.
Growing: Until seedlings are established, give them regular irrigation; do not, however, overwater. Mature plants survive some drought, but they thrive with sporadic irrigation in dry conditions. Rich soil is best for this plant’s growth, and little fertilizing may be necessary for the finest blooming. To promote bushiness, pinch off the growth stems, and deadhead to extend the blooming period. Bees and butterflies are drawn to this plant.
Harvesting: Select stems with freshly opened flowers for use as cut flowers. Remove any foliage that will be below the water’s surface and submerge it right away.
The centers of the blooms will darken and form compact clusters of seed at the root after the petals have fallen off. Remove the seed heads as soon as they develop a deep brown color and spread them out to dry for several days. Thresh the dried heads to separate the chaff from the tiny, arrow-shaped seeds. By keeping the cleaned seed in a cool, dry location, it is feasible to save Zinnia flower seeds.
In California, are zinnias perennial plants?
It’s hot outside, so gardening in the summer calls for plants that are minimal care, drought and heat tolerant, and have vibrant colors.
The better, the brighter.
On each of the three criteria, zinnias were suitable. plus more. They’re among the best flowers that savvy gardeners may use in their gardens, in fact.
If there is a flower that is simpler to grow, please let us know. Since zinnias are annuals, their life cycle from seed to flower to seed is short. Simple garden preparation is all that is needed for zinnias’ arrow-like, pointy seeds to germinate. Simply place them in soil that is well-drained, in full sun, and in an area that receives a lot of summer heat, and you’ll soon see small seedlings and blooming flowers. No enduring can boast of that speed!
One gardening buddy just scatters seeds wherever she wants a few zinnias, watered those areas for a few days, and then lets the zinnias’ naturally easy-to-grow nature take its course.
“Candy Cane,” “Green Envy,” “Persian Carpet,” and “Pop Art.” When a variety has names like those, color is guaranteed. The ridiculous color palette of zinnias includes every vivid and pastel shade (aside from blue), as well as bi-, tri-, and crazy-quilt combinations made for cutting, luring pollinators, etc.
Many new zinnia series give options for height and width in addition to vibrant color.
- While Zinnia elegans tall varieties continue to be the preferred option for the back of the border, shorter series are now challenging the low ground once held by marigolds and petunias. The Thumbelina Series of dwarf zinnias reach their highest point at 6 to 8 inches, whereas the Magellan Series remain roughly knee high at 14 inches.
- The Crystal Series and other creeping or spreading Zinnia angustifolia are a revelation for the front of the border, raised beds, containers, and even ground coverings. The fact that its native to Mexico is even more drought tolerant than regular zinnias makes it the preferred choice for hot locations like sidewalk beds or that no-man’s-land next to the garage.
- With a height of about 8 to 12 inches, ZaharaTM zinnias are renowned for their resistance to powdery mildew and leaf spot (see below). In the entry beds of the Regenstein Fruit & Vegetable Garden, we paired Zahara Yellow, which is brief but sweet, with tiny sunflowers.
Zinnias are obviously meant for the vase because they have style and long, sturdy stems.
The words stars and daisies, dahlias and spiders, buttons and domes, and quill-leaf cactus are all used to describe zinnia blooms. Flowers come in different varieties: “singles,” which have their petals arranged in a row around an open center; semi-doubles; and doubles. Each one is fantastic in floral arrangements.
The best zinnias for cutting are, of course, the tall kinds; “Benary’s Giant” is renowned for its three-foot-tall, robust stems and huge flowers. Just above a bud joint, angle-cut zinnia stems. Zinnias often stay a long time in a vase; thus, remove all but the most obvious leaves off the stems before placing them in water.
Zinnias require little upkeep. Because they grow quickly, they shade out weeds. They don’t need mulching, and the only fertilizer they need is an occasional application of a well-balanced mix.
Deadheading encourages the growth of additional blooms. Lack of time to deadhead? When it comes to a big bed, the Zaharas indicated in the sidebard are a significant time saver.
The Profusion Series, a cross between Z. elegans and Z. angustifolia, is resistant to powdery mildew, which is the bane of zinnias, just like Zaharas.
Zinnias are accustomed to dry environments because they are indigenous to the grasslands of the southwestern United States, Mexico, and South America. However, wet summers, like the one we’ve had so far, can be damaging. And leaf spot and powdery mildew can result from that. Three recommendations for surviving inclement weather:
- Only water as necessary, and then only at the plant’s base. Wet leaves can encourage the growth of mildew, and water splashing can instantly spread fungus from the ground onto zinnia leaves.
- Taller, mildew-prone kinds can be hidden by foreground plants.
- As one horticultural put it, “Even when zinnias are coated in powdery mildew, they’re covered with flowers,” do both #1 and #2 and accept that zinnia leaves (but not flowers) are impacted by wet weather.
Zinnia seeds can be saved with ease. Simply let the blossoms to completely dry on the stalk, gather the seedheads, and delicately crush them in your fingers to release the harvest of seeds for the following year. In the same manner as other seeds, store in a cool, dry area. (And save some for our seed swap in February of next year in a labeled envelope!)
Last but not least, zinnias attract butterflies, so plant them every year. The plants with larger flowers serve as landing places for butterflies looking for nectar. (The same is true with hummingbirds.) To capture the most attention, try tall zinnias with scarlet or hot pink blossoms.

For your summer garden, the ZaharaTM Coral Rose Zinnia (Zinnia Marylandica) excels and requires little water.
In Southern California, what flowers should I grow right now?
Alyssum, celosia, cosmos, gaillardia, gazania, lobelia, ageratum, marigold, morning glory, salvia, scabiosa, sunflower, statice, tithonia, and zinnia flower seeds can all be started outside right now. If you can start them under controlled heat and cover, the outcomes will probably be better.
Gardeners in beach cities can still grow pansies, stock, violas, and other cool-weather blooms.
Purchase a copy of Sunset’s Western Garden Book if you don’t already have one. Because it covers all of our tiny microclimates and is packed with useful information for Southern California, it is well worth the price.
It matters where you live and grow your garden in Southern California. Inland and central coast regions, the desert, and coastal regions near to the ocean all have distinctive climates. What works and what doesn’t must be learned as you go.
Heat-Resistant Plants in the Aster Family
This family of intricate yet timeless flowers can be found growing all across the globe, occupying sunny or high-exposure niches wherever there is plant life. Spreading flower crowns and slender, hairy green sections identify asters. They are the perfect plants for areas of your garden that receive full sun due to their delicate appearance and hardiness.
The zinnia
Latin America was the original home of the zinnia species. These lush-petaled asters enjoy the summer heat, according to the Denver Post. They flower from June to November and come in a variety of delicious colors, including deep, dark pink and honeydew green.
Purple Coneflower 2. (Echinacea purpurea)
According to Ohio State University, this heat-resistant plant exhibits very little leaf wilting even in the most arid situations since it can tolerate poor soils and dry weather. This species is both brilliant and subtle, with bright green, hairy stems that contrast with pink-lavender blooms and a central cluster of red-brown disc flowers.
3. Flower Blanket (Gaillardia species)
The southernmost regions of North America are where blanket flowers are indigenous, according to The Spruce. Their name refers to the gradual growth of each individual into a “blanket” of ground cover. This collection of heat-tolerant flowers prefer well-drained soil and direct sunlight and thrive in hot climates.
Black-eyed Susan 4. (Rudbeckia species)
Black-eyed Goldenrod ray flowers that extend from a center dark-brown cone of disc blooms give Susans their distinctive appearance. In direct sunlight, these distinctive asters self-seed. The Old Farmer’s Almanac states that they must germinate in soil that is at least 70 degrees.
Cosmos 5.
The cosmo is a legendary wildflower, boasting a spectrum of hues that matches echinacea and the delicate petals of a poppy. The American Meadows blog claims that the cosmos enjoy warm temperatures and full sun. Cosmos, however, are sensitive to extreme heat and can benefit from daytime partial or temporary shade.
This Latin American native enjoys dry soil and direct sunlight, according to SFGate. To add a splash of reserved, cold color to the bold, warm blooms that are typical of many summer garden blossoms, plant this kind of floss flower.
Pollinator Favorites For Your Garden
These pollinator plants will attract bees, butterflies, and beauty to your garden thanks to their vibrant hues, asymmetrical floral designs, and delicate foliage. These floral gems will blossom in all their splendor during the height of summer, unlike less heat-tolerant species that postpone their blooms until spring.
Egypt’s Star Cluster 1. (Pentas lanceolata)
These perennials, which are indigenous to east Africa, produce brilliant pink clusters of blooms with five petals. Their narrow, woody stems are supported by fluffy green leaves that are bright green on top and nearly silvery underneath. According to The Spruce, pentas flowers draw butterflies throughout their lengthy bloom season.
Lantanas, 2.
Lantana is a favored plant for butterflies, according to Southern Living. This blooming shrub, which is native to the tropics of Africa and the Americas, is evergreen. According to Sunset, it also draws hummingbird visits when blooming during the warmer season of the year.
Penstemons 3.
This diversified variety has trumpet-shaped flowers in shades of pink to purple that open wide to let bees and hummingbirds into your garden. Penstemons, according to Garden Design, are excellent for sustaining a variety of pollinators during the long, sunny days of summer. These exquisite plants will add flair and wildlife to any garden because they are abundant in pollen and nectar.
4. Gayfeather, also known as Liatris Blazing Star
The feathery, purple floral spikes and thin, grass-like leaves that define blazing star flowers. According to the Gardening Channel, this late-season bloom can sustain pollinators through the hottest months into fall.
Heat-Resistant Plants with Showy Flora
These equatorial splendors, which can be seen all along the midline of the planet, burst into color when the sun bears down on them.
1. the periwinkle of Madagascar (Vinca species)
This five-petalled flower, which is native to southern Africa, is possibly the most heat-resistant addition to your garden. How Stuff Works claims that the shades of Madagascar periwinkle range from deep purple to white. This plant’s ability to withstand both high heat and humidity is another trait that makes it adaptable.
Celosia 2.
There are about 40 native celosia species in Mexico, according to the Encyclopedia Britannica. With their brilliant orange to purple spikes, they give a striking element to any garden. Like many of its Amaranth family members, celosia self-seeds and thrives in rocky or poor soil.
Waxed Begonia 3.
This native of Brazil can withstand heat and humidity just as well as the Madagascar periwinkle. Its brightly colored petals and thick, waxy leaves shield it from the sun’s harsh rays, while a woody stem prevents it from wilting in humid conditions. According to Gardener’s Path, this amazing ground cover likes full sun to even the slightest amount of shade.
Heat-Resistant Plants That Grow Into Shrubs
Shrubs that can withstand high temperatures are essential for shading less tolerant plants. Pick a plant from this list that can withstand exposure to protect your garden on those hot summer afternoons.
Viburnum bushes
Viburnum species are widespread in Africa’s Atlas Mountains and thrive in North America as well. The Fine Gardening blog describes this group of heat-resistant plants as having subtle hairy leaves, white flower clusters, and dramatic red to black berries as their distinguishing features. These species can reach heights of four to fifteen feet, giving nearby plants the shade they need to survive.
Sage Tree 2. (Salvia arborescens)
The sage tree may grow to a height of 12 feet, and the National Gardening Association claims that it does pretty well in full sun. In the latter part of the growth season, hummingbirds and flowers find it to be attractive. In the late summer and early fall, sage trees can provide partial shade for plants that require it as well as for animals that seek out pollen.
3. Yucca
This inhabitant of the desert is virtually unbreakable. Some varieties of yucca can endure extreme heat, subzero conditions, and even wildfire. Yucca thrives in full sun and well-drained soils, according to SFGate. Every Bay Area garden can find kinds and species that are appropriate for their soil type.
