Your perfumed garden must have common purple lilacs. These lovely plants flower in late May with purple-blue blossoms. Although the blooms only bloom for a brief period of time (about two weeks in Colorado), they are resilient plants that are simple to grow and require little upkeep. These flowers appreciate direct sunlight and have a potent, sweet scent.
Although lilac blooms can come in a variety of colors, the deep purple kind is the most well-known. They are quite successful at luring important pollinators.
Make sure you have enough space for the kind you choose because lilacs come in a wide range of sizes and some can reach heights of 20 feet. Miss Kim Lilac is a nice smaller-sized lilac cultivar.
Roses
Many of the rose varietals that are grown in Colorado are not as fragrant. Austrian Copper Rose shrub variety is a great one that thrives here and has a mild perfume. These roses have yellow centers and reddish-orange outer petals. This flower’s aroma is licorice-like.
Rosemary
The lovely perennial plant rosemary has purple-blue blossoms and silver-grey foliage.
This plant grows well in full sun and can be enjoyed from spring through October. Rosemary plants have a maximum height and width of 4 feet. This herb is a wonderful addition to both food and fragrance gardens. The blooms can also be used to create essential oils.
Wisteria
Beautiful climbing wisteria comes in a variety of bloom colors, from purple and blue to white. The Chinese Wisteria and the Texas Purple Wisteria are two common cultivars in Colorado.
Wisteria is a flower that climbs and looks beautiful along garden borders and on pergolas. Heidrich’s advises allowing the plant enough space by taking into account how big it will be when it is fully grown. Give the vine something to climb on as well. Whatever you decide, it must be strong enough to support the weight and enough big to hold a growing plant. Be patient; it will take several years before you see blossoms. They only flower on new wood, though. A wind-free area is preferred by wisteria.
Hyacinth
Because they are resistant to deer and draw butterflies, hyacinths are a necessity for your scent garden. These fragrant blooms are available in a variety of hues.
Lavender
This lovely herb, which blooms from the summer through the fall, is a wonderful addition to any fragrance garden. The earthy, sweet perfume of lavender is well-known. From pink and white to purple-blue, the blooms can also be found.
Lavender makes a great companion plant since it deters deer and draws pollinators.
Sweet Alyssum
Alyssums provide your fragrance garden a wonderful splash of color and a delicate, sweet perfume. The common alyssum cultivars occur in a wide range of hues, from pure white to pink and yellow. The hue of perennial alyssums is more golden.
Alyssums bloom from spring through October and like full sun to partial shade. Your garden will attract pollinators thanks to these lovely, small flowers.
Peonies
Peonies are spring-blooming blooms that can reach heights and widths of 12 to 36 inches. They prefer full to some sun.
These scented blossoms might be pink, crimson, or white and have a crisp, delicate scent akin to a rose.
A fun fact: Ants are necessary for peonies to bloom. Don’t be alarmed if you see some ants on your peony; they are what causes the flower to open.
Daffodils
Daffodils, which bloom in April and grow 10 to 12 inches tall, are another fantastic flower that resists predators. These autumn-planted, spring-flowering bulbs like full sun to light shade.
Daffodils may give your scent garden a flash of orange, red, yellow, and even crimson. They have a nice vanilla scent that is pleasant.
Calendula
Calendula is the last essential flower to include in scent gardens. These vibrant blooms prefer full to partial sun and bloom from late spring to fall.
They have a yellow-orange hue and draw pollinators. They smell mushy and gritty.
Currant Bush
Currants are amazing deer-resistant and dual-purpose plants that are tasty. They blossom in the spring and have a pleasant scent.
Hummingbirds and bees in particular enjoy the currant bush as a source of pollen. Fruit from this shrub can be used to make wonderful jams and jellies.
Wisteria will it endure the winter?
Don’t panic if your wisteria begins to drop its leaves in the fall. Deciduous wisteria predominates. Winter doesn’t keep it green, but the leaves will come back in the spring.
Before dropping their leaves, some wisteria varieties put on a show of fall color as the leaves turn yellow or gold. If it’s happening in the fall, there’s typically nothing to worry about unless you’re also observing other symptoms like an insect infestation. Yellowing and dropping leaves can be signals of disease and other problems.
While Evergreen Wisteria (Millettia reticulata) is more challenging to grow, all true Wisteria are deciduous. Your Evergreen Wisteria will most likely maintain its leaves throughout the year if you have hot summers and brief, mild winters with little below freezing. This is zone 9b and higher in the US, which includes a portion of California and Arizona as well as the southern half of Florida and Texas.
Evergreen Wisteria is deciduous like regular Wisteria in more temperate regions, so you may anticipate it to go dormant for the winter and sprout new leaves in the spring. You probably won’t be able to cultivate Evergreen Wisteria in a location that is colder than USDA zone 8 because even deciduous habit cannot shield it from prolonged, bitterly cold winters.
Where does wisteria grow?
It is well known that wisteria take a very long time to bloom. For two to three years after planting, don’t anticipate blossoms. Some readers have sworn by this method to spur on blooming:
- To cut into part of the roots, take a shovel and drive it 8 to 10 inches into the ground approximately a foot and a half away from the main trunk of the wisteria.
- Approximately half of the roots should be damaged for the shrub to be shocked into reproduction (flowering).
- Don’t worry—impossible it’s to harm this unchecked, unwieldy, frequently invasive shrub!
- The flowers of wisteria can also be impacted by chilly winter temperatures.
Native Wisteria
Consider growing a wisteria species that is indigenous to North America if you live there, such as:
- Wisteria frutescens, also known as American wisteria, thrives in zones 5 through 9. Its original states span from Virginia to Texas, the southeast to Florida, and up into New York, Iowa, and Michigan in the north. The vine is 25 to 30 feet long, has glossy, dark-green leaves, and after the plant has begun to leaf out, develops huge, drooping clusters of lilac or purple-blue flowers. Only new wood will display the blossoms. Notably, the blossoms are typically less aromatic than those of Asian wisterias.
- In zones 4 to 9, Kentucky wisteria (Wisteria macrostachya) flourishes. Similar to American wisteria, this late-bloomer is a native of the Southeast of the United States (it is sometimes considered a variety or subspecies of American wisteria). The Kentucky wisteria is the quickest to blossom, bearing faintly fragrant bluish-purple flowers after only two to three years of growth.
- A gorgeous, silvery-blue cultivar of the native Kentucky wisteria called “Blue Moon” is particularly hardy. In late spring or early summer, it blooms. It can go as chilly as -40F. (-40C).
Non-Native Wisteria
- Despite the fact that they are frequently marketed at nurseries and garden centers, Chinese wisteria (Wisteria sinensis) and Japanese wisteria (Wisteria floribunda) are non-native, invasive species, hence we do not suggest them for North American gardens. They can reach lengths of 30 to 60 feet and are hardy in Zones 5 to 9. (and beyond in the Southern U.S.). Japanese wisteria comes in two popular kinds, including:
- Popular plant known as “Honbeni” displays clusters of pink flowers in the late spring.
- “Alba” (also known as “Shiro Noda”) yields beautiful clusters of snow-white flowers in the late spring.
Are Wisteria Toxic to Pets and Humans?
Yes, the wisteria plant contains lectin and wisterin, which are poisonous to people, animals, and even pets. If taken in significant quantities, these poisons can result in anything from nausea and diarrhea to death.
If pets or young children frequent the area, it is a good idea to remove the seedpods after the plant has flowered because the material is particularly concentrated in the seeds and seedpods. Unaware children or animals won’t think twice about eating as many seedpods as they can because they are not unpleasant to taste or have an instant effect. In case of ingestion, contact your neighborhood poison control center.
Wisteria can it grow in snow?
Wisteria (Wisteria spp.) plants have long pendants of fragrant purple or white flowers that dangle in a weeping manner. They are a favorite flower for climbing over arbors, training up a wall, or growing as a conventional tree. When grown, wisteria can readily withstand harsh winters and flourishes in U.S. Department of Agriculture plant hardiness zones 4 through 9. However, young wisteria plants might not be able to withstand the first winter after planting without some protection from frost and chilly winds.
In the fall, water the wisteria plant frequently to maintain moist but not soggy soil. The plants may move nutrients from the soil and store them for the winter by receiving regular watering in the fall. When freezing conditions are predicted, water plants liberally to prevent desiccation of the leaves when the temperatures cause the moisture inside to freeze, leaving frost on the leaves.
To protect the vine’s roots from the cold throughout the winter, cover the base with a 4-inch layer of organic mulch. Anything from crushed bark mulch to dried leaves can be used. To ensure the entire root ball is insulated, keep the mulch a few inches away from the vine and cover a space that is at least 2 feet in diameter.
Wrap the main stem of the wisteria plant with a section of thin-walled plastic tubing. With a razor knife, cut the tubing lengthwise, then pry it open to allow it to fit around the wisteria stem. The plastic tubing is less expensive than using frost cloth or leftover fabric, which are typically far larger than what is required for the stem.
Create a temporary walled enclosure to safeguard the plant. Using a reciprocating saw, extend four 2-by-2-inch wooden posts by about 24 inches beyond the height of the wisteria. Using a hammer, pound the four stakes about 18 inches into the ground. Place the stakes evenly spaced around the plant, 18 inches from the stem.
Frost cloth, burlap, or another type of fabric can be used to cover the stakes. Without letting air escape around the plant’s base, the cloth must be big enough to completely cover the structure. If you require more than one piece of cloth, make sure the ends are at least six inches apart. Set up some bricks or rocks on the ground to hold the extra length in place. The inside temperature of the building stays higher than the outside temperature thanks to the heat that is radiated from the ground surrounding the plant and is trapped by the frost cloth or fabric.
The greatest places for wisteria trees to grow
The greatest way to utilize wisteria’s breathtaking beauty and incredible vitality is to grow it as a little tree, or standard. Long racemes of sweet-smelling May flowers hang down from soft, pruned leaf heads and sway slightly with each breeze. The compact head of a Tree Wisteria looks amazing in a mixed bed of perennials, bulbs, and annuals. The impression is beautiful and dignified.
Please be aware that wisterias typically take a while to emerge from dormancy after planting. Please be aware that your plant won’t start to leaf out until early summer. It will thereafter leaf out at the usual time in succeeding years (midspring).
Choosing a Location: Wisterias grow and flower most effectively in areas with plenty of sunlight, preferably at least 6 hours every day. They do well in any kind of soil as long as it drains well.
In order to plant your bareroot Wisteria, take off the packing and give the roots a few hours in a bucket of water. Then, dig a hole that is both large enough to permit the roots’ spread and deep enough to allow you to set the crown, or the location where the stem and roots converge, 1 inch below the soil’s surface. Insert the roots into the planting hole and arrange them naturally or like the spokes of a wheel. The roots of many woody plants are brittle, so use additional care when positioning them in the planting hole to prevent breaking them. With one hand holding the crown 1 inch below the soil’s surface, use the other to push soil into the hole while circling the roots to prevent air pockets from forming. Then, using both hands, compact the soil close to the crown. To create a basin, create a rim of earth around the perimeter of the planting hole. This basin is used to collect, hold, and direct water to the roots. Finally, thoroughly immerse the plant.
Please be aware that once bareroot plants are taken out of their packing, they dry up rapidly, especially on a sunny, windy day. Until you are ready to plant, we strongly advise that you keep the roots wrapped in wrapping material.
Staking: To keep their heads aloft in severe gusts, tree wisterias need additional support. After planting, drive the wooden stake that came with your tree 6 to 12 inches deep and 1/2 inch away from the plant’s trunk into the earth. Using the plastic tie tape that came with the tree, affix the trunk to the stake numerous times, spacing them apart by about 8 inches. You’ll need to swap out the original stake for a bigger wooden stake or a sturdy steel pipe as the head and trunk grow bigger. Check the tree every spring and autumn to ensure that the stake is securely in place and that the tie tape used to attach the trunk to the stake is not excessively tight and preventing the trunk from expanding. Plants need to be firmly staked at all times.
Watering and Fertilizing: To hasten wisterias’ establishment in the first year after planting, they require the equivalent of 1 inch of water each week. If the sky doesn’t provide enough moisture, water deeply once a week. Plants that are established only require irrigation during extended dry spells. Wisterias don’t need much, if any, fertilizing because too much fertilizer prevents blossom. Give plants a gentle feeding of 5-10-10 or 5-10-5 at a rate of 3/4 cup per square yard in the early spring each year if your soil is particularly weak or sandy.
Overwintering: For the first few winters after planting, cover the main stem with a piece of plastic tubing in cold-winter conditions like ours here in Litchfield (Zone 5 [-20F]). To encircle the stem, make a straight incision from one end to the other and pry the cut open. (Precut tubing could be available at your nearby garden center.) To stop wind and frost from damaging branches on older specimens, cat’s-cradle bind the branches together using twine to form a web of intertwined strings.
Pruning: Tree Wisterias need to have the long, twining branches they generate in the summer pruned lightly but frequently in order to maintain the globe shape of the head. A couple of weeks prior to the first date of your first frost, they also require one severe pruning in late summer or early fall. Remove all branches that are in the wrong place and reduce the current season’s development to just 5 to 6 huge buds (leaving stubs that are about 6 inches long). This drastic haircut inhibits growth and promotes the transformation of some leaf buds into flower buds. Don’t let pruning errors keep you up at night. Wisterias are highly understanding plants; strong growth the following season will give you another chance.
