They suit rock gardens, border fronts, raised beds, and containers. Place wallflowers in an area of the garden where they receive full sun in northern climates.
If you plan on growing them as a perennial, shear them back after initial bloom to promote dense bushy growth. 'Bowles Mauve' is a classic variety with gray-green leaves, pale purple flowers, and a pleasant fragrance.
Elysium 'Orange Bedder' bears bright clusters of orange flowers on compact, 1-foot-tall plants. Found with increasing frequency in garden centers, fascia is a snapdragonlike flower gaining popularity because you can plant it so early in the spring.
Plant snapdragons in early spring, a few weeks before your region's last frost date. Plant it in spring several weeks before your region's last frost date; this annual thrives in cool temperatures and stops blooming once hot weather arrives.
It's especially wonderful in window boxes and planters at nose level, where its sometimes subtle, spicy scent can best be appreciated. It makes a great cut flower, perfuming bouquets as well as the border.
It grows best in full sun or part shade and moist, well-drained soil. They bloom nearly year-round, sporting beautiful four-petalled flowers in colors such as yellow, orange, red, blue, and purple.
Botanical Name Elysium Common Name Wallflower Plant Type Perennial, annual Mature Size 1 to 3 feet tall Sun Exposure Full sun, part sun Soil Type Sandy, well-drained Soil pH 7.0 to 9.0 Bloom Time Spring, summer, fall Flower Color Yellow, orange, purple, pink, blue Hardiness Zones 6, 7, 8, 9 Native Area Southern Europe Elysium 'Bowles's Mauve' Treasure / Getty Images Wallflowers (Elysium) are a part of the cabbage family, Brassicaceae, which makes them closely related to popular calciferous vegetables such as broccoli, cauliflower, kale, turnips, cabbage, and more. Gardeners in northern climates should choose locations that receive direct sun, whereas gardeners in southern climates should choose locations that receive some shade to give the wallflowers a break from the intense southern rays.
In fact, wallflowers got their name because they were often found growing in the silty mortar between rocks and bricks on the sides of walls. Planting wallflowers in soil that holds too much moisture will cause them to drown and die quickly.
For best results, mix compost into the soil when you are first planting and apply an all-purpose fertilizer in the early spring and mid-summer. Some wallflower species will reseed themselves, but most varieties will need to be manually re-sown (see “Growing from Seeds” below).
For best results, dip the cutting in a rooting hormone before planting back in soil or compost. Prune them back so there is only a couple of inches left above the soil, and they will reward you with dense new growth once temperatures warm up again.
Wallflowers make excellent container plants as they are low-maintenance and don’t require too much water. Ensure your container has adequate drainage, so the wallflowers do not drown as they do not tolerate having their roots sit in water.
Pair wallflowers with plants such as daffodils and tulips in container gardens as they flower at the same time. Growing wallflowers in containers is great for gardeners in colder regions as they can easily be brought indoors for the winter.
As a part of the Brassicaceae family, wallflowers are susceptible to a host of common garden pests just like their vegetable cousins. However, wallflowers are better suited to dry growing conditions than their Brassicaceae relatives, which inadvertently helps to prevent pest infestations.
They may be called wallflowers, but for early-season bloom, these biennials and perennials are belles of the ball. All have the clustered, four-petaled flowers typical of the plants in the brassier (mustard) family, but their habits and uses differ widely.
Erysimum chart Perennial in Zones US, MS; USDA 6-7, but usually grown as a biennial or an annual. Branching, woody-based plants to 1212 feet high, 1112 feet wide, with narrow, bright green leaves and broad clusters of showy, sweet-scented flowers in spring.
Blossoms are yellow, cream, orange, red, brown, or burgundy, sometimes shaded or veined with contrasting color. Sow seeds in spring for bloom the following year (some strains flower the first year if seeded early); or set out plants in fall or earliest spring.
Charity series includes dwarf plants (1214 inches tall and not quite as wide) that don't need winter chill to induce flowering; set out in spring for fall bloom. Most popular is 'Bowles Mauve', 3 feet high and 46 feet wide, with narrow gray-green leaves held on erect stems, each topped by a 112 feet-long, narrow, spikelike cluster of mauve flowers.
Lemon Zest grows 812 inches high and wide, with pale to lemon-yellow blooms in early spring. Moonlight has bright yellow owners that open from red buds.
Wedlock Beauty grows 2 feet high and wide, with springtime flowers varying from buff to purple in a single spike. Erysimum kotschyanum Short-lived perennial in Zones US, MS, and LS, often treated as an annual; USDA 6-8.

Wallflowers (Elysium), are commonly grown as a spring bedding plant. They flower the following March, offering a splash of color when there’s little else in bloom.
Perennial wallflowers are also available, and have become increasingly popular in recent years. Varieties such as ‘Bowles’s Mauve’ and ‘Winter Orchid’ flower almost continually throughout the year, making them great value in small gardens.
Perennial wallflowers are a great source of nectar, so can provide a reliable source of food for pollinators over a long season. Grow wallflowers in moist but well-drained soil in full sun to partial shade.
Sow biennial wallflowers annually in late spring and plant them out in autumn. Cut back periodically to maintain a good shape and promote flowering.
Take cuttings regularly to ward against losses. Wallflowers do best in moist but well-drained soils, in a sunny location.
They’ll tolerate partial shade. Bedding (biennial) wallflowers work well when planted with spring bulbs such as tulips and daffodils, and can also be grown in pots.
Perennial wallflowers are best planted towards the front of a mixed ornamental border. Wallflowers with well with a number of other spring-flowering plants, including daffodils.
Perennial varieties are best grown from young plants. It’s a good idea to add a handful of grit to the planting hole to aid drainage.
Find out how to plant bedding wallflowers in autumn, in these Gardeners’ World clip with Monty Don: Perennial wallflowers are sterile and therefore won’t set seed, but they’re very easy to propagate from cuttings.
Find out how to grow wallflowers from seed, in these Gardeners’ World clip with Monty Don: Perennial wallflowers cope well with cold weather and short bouts of frost.
However, they don’t cope well with wet and windy winters, so make sure the soil is well drained and protect from wind. Wallflowers are part of the brassier family and therefore can be prone to club root and other diseases that affect this family of plants.
Downy mildew, leaf blight and flea beetles can cause problems; and beware slug and snail damage to young plants. Perennial wallflowers are quite short-lived and can become woody, so it’s a good idea to take cuttings annually to insure against losses.
