Liatris is a summer-blooming perennial with grassy foliage and fuzzy, bottle-brush flowers. Commonly known as blazing star or gayfeather, this North American wildflower makes an attractive addition to flower gardens, cutting gardens, landscaped areas and informal plantings. The distinctive flower spikes stand 2 to 4-feet-tall and are magnets for butterflies.
Liatris grows from a bulb-like corm. Longfield Gardens supplies large, grade #1 corms (shown far left) that grow into healthy plants with strong root systems.
SUN AND SHADE: Liatris grows best in full sun, though the plants will also tolerate some shade.
ZONE: Liatris are winter hardy in zones 3-8. Not sure about your hardiness zone? Check the USDA zone map here.
WHEN TO PLANT: Liatris corms are planted in spring, when the weather is cool and it's easy for the young plants to get established. Flowers usually appear the first year, approximately 70 to 90 days after planting, and the plants will return to bloom again for many years to come.
Liatris grow wild in meadows and prairies throughout many parts of the U.S. Though the plants prefer well-drained soil, they will tolerate more moisture than many other garden perennials, so are often included in rain gardens.
Liatris is an eye-catching addition to flower gardens. The stately, wand-like flowers bloom in mid to late summer. Flower color is typically amethyst-purple and there are also cultivars with pink or white flowers. Liatris look beautiful in summer flower arrangements, so they are a good addition to cutting gardens.
As a native plant, liatris is vigorous enough to hold its own when planted in a meadow, native plant garden or naturalized area. The flowers attract a wide range of butterfly species, so they are a must for butterfly gardens. Liatris is a good companion for ornamental grasses, and is especially attractive when planted in large sweeps or drifts.
The corms may be planted individually or you can dig a larger hole and plant several bulbs at the same time.
Loosen the soil to a depth of 6-8”.
Dig a 3” deep hole and place the corm(s) inside with the smooth side down and the sprouts facing up. Space the corms about 5" apart on center.
Cover and add water if the soil is dry.
Liatris are tough plants, but if the weather is dry, the newly planted corms should be watered weekly until they have established a strong root system. As with all bulbs, avoid over-watering.
After the first couple months, liatris will need little to no attention. The plants are relatively drought tolerant, naturally pest and disease resistant, and deer usually ignore them.
When liatris have finished blooming, the flower stalks may be cut off at the base of the plant. That said, the flowers provide vertical interest even after their color has faded, so feel free to leave them standing -- especially in naturalistic plantings.
