Any of the about 300 species of perennial herbs or shrubs of the family Geraniaceae, which are primarily indigenous to subtropical southern Africa, are geraniums (genus Geranium), also known as cranesbills. The most popular plants for greenhouses and bedding are geraniums. Around 280 species of annual, biennial, and perennial herbaceous plants known as geraniums belong to the closely related genus Pelargonium.
The Pelargonium genus contains cultivated geraniums that range in texture from herbaceous to woody, with thick fleshy leaves that can be spherical, lobed, or deeply cut. The terminal clusters of flowers range in color from white through pinkish hues to deep crimson and violet. Hybrids make up the majority of cultivated species. There are options for ragged or frilled petals, varied colors, and double blooms. Geraniums can also be grown from seed, though they are typically propagated via stem cuttings, from which flowering plants can be generated in four to five months. A line of seed geraniums that are useful for bedding because of their uniform symmetry, lengthened flower stalks, and propensity for quick and tidy flower petal shedding has been developed through breeding and selection.
What makes geraniums unique?
Geraniums Can Survive Drought As long as they are placed in well-draining soil, these plants thrive in warm, sunny environments and require only moderate to frequent watering. They are great choices for container gardening because they require little maintenance.
Hardy Geraniums vs. Pelargoniums
Pelargoniums should not be confused with hardy geraniums. You might be wondering what makes a geranium different from a pelargonium. Similar to some siblings, they are both members of the same plant family, but they could not be more unlike.
Pelargoniums cannot withstand frost, while hardy geraniums can. Pelargoniums are usually treated as annuals and replanted each year, but true hardy geraniums are perennials that grow back every year. Pelargoniums die in the winter.
Prune your Hardy Geraniums
Your sturdy geraniums will look their best and promote new growth if you prune them properly. By correctly pruning your hardy geraniums after the blooming season, you can encourage repeat blooming. The majority of geraniums can be cut back twice in a single season, which allows them to bloom at least three times.
When to Prune
Your hardy geraniums should be pruned in accordance with the season you are in. Rozanne will require various cuts in the spring, summer, and fall. To maintain your blooms rich and healthy, mark your calendar and adhere to our seasonal trimming recommendations.
What tools you need
Your geraniums may be pruned fairly easily. All you’ll need is the ability to prune, a pair of sharp pruners, your favorite mulch, and your favorite gardening gloves. Watch this video to learn more about pruning strategies in detail.
How to prune
You shouldn’t be concerned that pruning your flower’s back will harm her. The majority of hardy geraniums require trimming to promote new growth and prevent them from encroaching upon other plants.
Trim the plant back to within a few inches of the ground or to about an inch above the main stem once the flowering is completed or you find old growth. Remove any brown stems or yellow leaves after that by going inside.
Soon after trimming, more leaves will start to appear. Some resilient geraniums even have the ability to blossom again. Maintaining correct pruning on your plants encourages new development and keeps them from spilling out throughout your landscape.

Is a geranium a perennial or annual plant?
Geraniums actually belong to two different botanical subgroups. The perennial varieties are the real geraniums. The geraniums that most people envision when they go plant shopping are the annual bedding varieties with flowers that resemble lollipops and are mounted on stick stems. The plant genus Pelargonium includes several bedding plants. Ivy geraniums, aromatic geraniums, and Martha Washington geraniums are just a few of the numerous additional geraniums that belong in the Pelargonium genus.
When will geraniums bloom?
My geraniums are no longer blooming. I fed them, but it was ineffective. What’s the issue?
You might be feeding them too much. Pelargoniums, a genus of geraniums native to the Mediterranean, flourish in full sunlight and relatively infertile soil. Overfeeding can be the issue if you have a lot of foliage growth and the plants appear healthy. For a while, stop giving them food. But if your plants are becoming older and their stems are getting lanky, it might be time to propagate. Although they can live much longer, geraniums typically only bloom for two years on average before becoming woody and losing their blooming ability. Thankfully, geranium propagation is simple. Simply cut stem tips with at least two pairs of healthy leaves from a four-inch stem. Cut the stem at the lowest point, dunk it in hormone rooting powder, and then plant it in a mixture of half sand and half peat moss. In around three weeks, repot in ordinary soil after providing adequate watering and covering with plastic to assist preserve moisture. Sticking the cutting in water and letting it grow roots before potting is a simpler method.
Rose, The Queen Of Flowers
The “Queen of Flowers” is another name for one of the most well-known flowers of all time. Absolutely not just for girls, English gardens, or romantics! The amazing element rose is sometimes misunderstood. While the adjectives “feminine,” “floral,” and “powdery” have long been associated with roses, they do not exclusively describe their aroma. Some rose species also have “clean,” “masculine,” “woody,” even “fruity” undertones.
Rose in Perfumery
a strong flowery note. In addition to coming in a wide range of colors and sizes, roses are found all over the world. However, hybrid roses have unhappily lost their aroma as a result of the widespread cross-breeding of roses to produce a rainbow of colors. The two species of rose utilized in perfumery are Damascena and Centifolia. In perfumery, there are two different types of extracts for roses: absolute and essential oil (deeper and sweeter than its oil counterpart). Rose has endured because of its exceptional ability to meld with other floral, wood, and citrus notes.
Numerous chemicals are present in rose extracts, which explains why the fragrance is so complex and multifaceted. Citrusy (lemongrass) notes, green, fruity (peach, plum, wine), spicy (clove), amber, and sweet notes are all present in one single aroma of rose perfumery extracts.
Rose Essential Oil and Absolute
The essential oil from roses, especially Rosa centifolia or may rose and Rosa damascena or damask rose, is extracted using steam the same day after they are hand-picked in the early morning when the aroma is strongest. Rose water that hasn’t been utilized in the steaming process is frequently used in desserts, but you may also find it in some perfumes to give them a milder scent.
The most well-known countries for producing roses are probably Turkey, Bulgaria, France, and Morocco, but they aren’t inexpensive! The most expensive rose oil used in perfumery is the pure variety. It’s vital to avoid blending the same type of oil from different geographical places because the quantity of rain and sunshine a rose receives might vary its perfume. Otherwise, you might get something really intriguing.
Rose absolute, which is rose in its purest form, will provide you with the most robust rose profile of all of the varietals.
The Chemistry Of Rose
Each flower species is made up of a variety of components, some of which are in charge of imparting the aroma. Linalool, adlehydes, geraniol, and citronellol are only a few of the 300 compounds found in roses. Roses naturally contain rose oxide, a chemical with a metallic aroma. Watch out for the natural indole component, which can give rose oil a slightly rotting odor and is found in most flowers.
The world of perfumery is so exciting because of these compounds! You may not only duplicate the rose’s fragrance (at a lower cost), but you can also recreate the same rose repeatedly without worrying about its origin or harvest! Additionally, it means that you can generate an infinite number of rose scents that are not present in the actual blooms! The purest form of experimentation.
Geranium, A Masculine Rose
Strong-smelling comes from the Latin Pelargonium graveolens. And it definitely is!
When you think about geranium, images of flower boxes on window sills filled with lovely pink and red flowers sitting beautifully and filling the air with their perfume likely come to mind. The leaves, not the blossoms, are what give off the aroma. A geranium leaf will smell of citrus and fruit with a tinge of spice and, of course, a rose scent when crushed between your fingers.
Geranium is typically confused for “the other” rose because of its perfume, although it has a less powdery and more lemony, herbaceous aroma and a subtle but strong warm green scent.
Geranium in Perfumery
Its widespread use in soaps and lotions gives it a perfume that is thought to be “soapy,” which is why rose is also frequently utilized in fragrances for men.
The flower note geranium is excellent for tying together your top and base base notes and enhancing any other rose-based components in your composition.
Geranium Essential Oil
Geranium oil is made by distilling the leaves and stalks, much like rose oil. The drink smells crisp and vegetal green, with a pleasant undertone of mint and rose. It is far less expensive to obtain than rose!
Geranium, on the other hand, has an aromatic quality (similar to lavender), making it smell more “masculine” to some noses, whereas rose typically has a sweeter scent. Because of this, the extract is employed in numerous manly fragrances, as well as the typically masculine Fougere and Chypre accords, even though everyone seems to like its scent.
Noble geranium absolute, which is a richer, deeper extract than its essential oil equivalent, but also more expensive.
The Chemistry of Geranium
Citronellol, nerol, geraniol, and linalool—all well-known compounds in geranium oil—are among the numerous chemicals they share with rose, which explains why they have comparable fragrance profiles. Nerol, which is present in lemongrass and contributes to the lemony flavor of geraniums, and geraniol, which is one of the main ingredients in rose oil and gives geraniums their rosy aroma.
Do geraniums survive the cold outside?
- Make sure you thoroughly inspect your geranium plants before bringing them inside for the winter. Look for symptoms of pests and illnesses like rust and remove any dead leaves or wilting blossoms. Only zonal pelargoniums are impacted by this, but it is becoming more widespread. It arrived in the nation for the first time in 1968, and it does best in the moist summer or fall months. Fortunately, it doesn’t seem to spread to the plants quickly and is simple to treat, so merely plucking the afflicted leaves is an effective management. You might also consider using the fungicide Dithane 945 as a spray.
- Placing your overwintering plants somewhere bright and sunny will help them retain their need for light throughout the winter. Your plants will receive 50% less light if they are placed more than three feet from a window!
- Because your plants continue to thrive throughout the winter, keep the roots moist. While geraniums frequently survive droughts, they rarely flourish. Show plant growers take special care to keep the roots of their plants damp but never soggy during the winter.
- Ventilate as frequently as you can to maintain a dry environment surrounding your plants. Your plants will turn into a moldy, rotting heap if you don’t allow the air to circulate. The greatest electric fan heaters are those that operate automatically since they circulate air while simultaneously raising air temperature.
- Geraniums are fairly inexpensive to overwinter in the greenhouse because they only need to be kept frost-free. To keep temperatures above freezing, however, we do advise utilizing a heater. Set the thermostat on your heater to 5C, which is 41F. The plant will not survive if the stems become frosty! The winter months are a great time to store your delicate pelargoniums in porches, sunrooms, or conservatories.
We hope that we have provided you with enough of tips so that you can continue to enjoy your geraniums year after year.

Do geraniums like shade or the sun?
Wish your life had a little more carefree beauty? Plant some geraniums, maybe. Geraniums are beautiful and low-maintenance plants that belong in planters, planting beds, and perennial borders.
Geraniums can be divided into two major groups. Zonal, fancy-leaf, ivy, perfumed, and Martha Washington (or regal) varieties of annual geraniums (Pelargonium species), which often only live for a year, are some examples. Perennial geraniums (Geranium species), which bloom continually from spring to summer, combine striking foliage with attractive blooms that emerge intermittently or continuously.
Where to Plant Geraniums
You must be aware of the type of geraniums you have in order to select the ideal planting location. With the exception of the ivy geranium, which thrives in mild shade, most annual geraniums require a location in full sun. On the other hand, depending on the variety, perennial geraniums can grow in either sunlight or shade. In the country’s southern and western regions, both types profit from shielding from the sun during the warmest time of the day.
What Kind of Soil to Use for Geraniums
Geraniums grow best in healthy, well-draining soil, which is ideal for both perennial and annual geraniums. Improve soil drainage and quality when growing geraniums in planting beds by adding 3 inches of Miracle-Gro Garden Soil for Flowers to the top 6 to 8 inches of native soil. When growing geraniums in pots, Miracle-Gro Potting Mix should be used because it is light and fluffy. For the ideal planting medium, combine garden soil and potting soil in equal portions, or fill raised beds with Miracle-Gro Raised Bed Soil.
How to Plant Geraniums
Starting with young plants, such as the premium geraniums from the Miracle-Gro Brilliant Blooms collection*, is ideal (and simplest). Geraniums, both annual and perennial, benefit from warmth, so postpone planting in the spring until all risk of frost has passed. Once the summer heat subsides in the fall, you can also plant perennial geraniums. Try planting perennial geraniums from late fall to early spring in areas with mild winters.
Geraniums range in height from 4 to 48 inches tall and 6 to 36 inches wide, depending on the variety. For information on the recommended spacing for your type of geranium, consult plant tags. Use a pot that is at least 10 inches across for annual geraniums or at least 12 inches across for perennial geraniums when planting geraniums in pots.
Geraniums should be watered thoroughly after planting, giving the root ball and surrounding soil time to absorb the water.
How to Water Geraniums
Check the soil once a week for annual geraniums, and water when the top inch is dry. During their initial growth season, keep newly planted perennial geraniums in continuously moist soil. With the exception of periods of extreme drought, perennial geraniums can typically thrive on rainfall after they are established.
How to Mulch Geraniums
After planting geraniums, cover the area with a 2- to 3-inch layer of mulch to help keep the soil moist and to prevent weed growth and sun exposure. Use Scotts bagged mulch, chopped leaves, pine straw, or another material that is easily obtainable in your area.
How to Feed Geraniums
Your plants receive an excellent starting dosage of nutrients when you start with rich, nutrient-rich soil. However, you should also feed them frequently all season long for maximum results. Apply Miracle-Gro Shake ‘n Feed Rose & Bloom Plant Food to your geraniums a month after planting to give them the extra boost of nutrition they require for magnificent blooms. Make sure you adhere to label directions.
How to Grow Perennial Geraniums
Even in the coldest climates, perennial geraniums don’t require particular care to survive the winter. After the initial flower flush, cutting perennial geraniums back by around one-third can encourage more blooms. Cut stems back as necessary if hardy geraniums like “Rozanne” or “Pink Penny” spread out too quickly and widely. These vining geraniums can have up to two-thirds of their length removed, and the plants will still grow back. To encourage new growth and prevent wilted leaves, prune cranesbill geraniums to 2 to 4 inches height after flowering.
How to Use Geraniums
Annual geraniums are excellent at stealing the show in planters and flowerbeds. Regal geraniums can resist cool weather and form lovely hanging basket plants, making them an obvious choice for planting in the early spring. Ivy geraniums are very stunning. Geraniums with aromatic leaves are strong in containers and form a lovely patio display where the leaves may be stroked and enjoyed.
In gardens with some shade, perennial geraniums add much-needed color and can thrive next to mature trees. While mid-size perennial geraniums go well with lanky shrubs, shorter perennial kinds create beautiful ground covers.
