Details



Liatris, commonly known as Gayfeather or Blazing Star, is a small North American genus consisting of about 30 species. A member of the Aster family, the plants form a low clump of grassy lily-like leaves and at the beginning in midsummer, bear tall spikes of flowers, each spike comprising of tiny flowers.

Liatris spicata 'Floristan White' is a selection from Germany that was bred specifically for cutting, it is widely grown as a commercial cut flower. This variety throws up 60 to 90cm (24 to 36in) spikes of densely packed, pure white flower spikes in July and August. 'Floristan White' add height to flower beds and provides a cool contrast to hot-headed summer blooms.
Liatris are long-lasting in the garden and in flower arrangements, the flower spikes can also be dried for winter use in arrangements. The spikes bloom starting at the top and working their way to the bottom, and if cut for bouquets when only blooming near the top, the spikes' buds will open day by day, and the spent top can be trimmed as it fades.

In the garden, Liatris is a valuable addition to perennial gardens as a vertical contrast to mounded or broad-leaved plants and look particularly attractive when planted in large sweeps or drifts in informal settings. They are at home in the meadow or naturalised areas. Bees and butterflies enjoy the nectar in summer and the birds love the seeds in the autumn. Small birds such as finches will cling to the spikes in late autumn or early winter to eat the feathery seeds.
Clumps may be massed together to make a bold statement in a bed or repeated throughout a border to provide exclamation points that contrast with more rounded or bunched blossoms. The blooms are long-lasting whether in the garden or as a cut flower.



Sowing: February to May or September to October.
Start Liatris seeds indoors or sow them directly in the garden in early spring.
Sow the seeds on the surface of lightly firmed, moist seed compost in pots or trays. Cover seed with a light sprinkling of compost or vermiculite. Place in a propagator or warm place, ideally at 14 to 24°C (55 to 75°F). Keep the compost moist but not wet at all times, water from the base of the tray. Germination 20 to 25 days.
Prick out each seedling once it has its first set of true leaves and transplant into 7.5cm (3in) pots containing free-draining compost and grow them on in frost free conditions until large enough to plant outside.
Gradually acclimatise to outdoor conditions for 10 to 15 days before planting out after all risk of frost has passed. Overwinter autumn sown plants in frost-free conditions before planting out the following spring. Plant 30 to 60cm apart.
Transplant in well drained soil in full sun, if the soil is rich, the stems get floppy. The plants dislike wet ground, particularly during winter. Improve heavy soil conditions by adding coarse grit or sharp sand prior to planting.


Cultivation:
Liatris grows best when planted in full sun and well-drained soils. The plants are very drought resistant and are not fussy about soil types as long as the drainage is good. They will tolerate some shade, and poorer soils. Space the plants 30 to 35cm (12 to 16in) apart, this will allow for sufficient sunlight and air circulation among the stems to prevent Botrytis from developing.
Liatris should be planted as early as possible in the spring after the last possibility of frost, but can also be planted in late summer or early autumn when cooler temperatures return. Water plants regularly during the first growing season to establish a strong root system. Once established, Liatris plants are fairly drought tolerant. Do not overwater, Liatris seeds grow into corms and resemble small bulbs and if allowed to sit in constantly wet soil the corms will rot.
Fertilise before new growth begins in the spring using an organic fertiliser. Do not over fertilise as the flower spikes will flop over if plants are grown in overly fertile soils.
When the flowers are dried and spent, they still have a browned decorative value for a little while in autumn, but by November they look dead. The blackened dried flower spikes may persist in winter and it's up to individual tastes whether to prune them right away or wait until spring.


Division:
Established plants do not need dividing until they either die out in the centre or become clumps that are too big for the available space. If this occurs, divide the tubers in the autumn or spring just as leaves are emerging. Dig up the clumps and separate the corms or cut tuberous roots with a sharp knife or shovel, keep at least one eye on each division.


Seed Collection:
Wait until the flower heads on the entire stalk have turned fluffy tan before collecting in October. Bring the stalks inside to air-dry then shake or brush the nutlets from the heads. Seeds can be cleaned or stored with chaff in sealed, refrigerated containers.


Cut Flowers:
Liatris spicata is the most prominent species that is commercially grown for florists. It make a great cut flower and can be used fresh or can be dried. Harvest the spikes in the morning, look for stems with about a quarter to a third of the blooms open. You may use tighter flowers, but you’ll have to use a full-dose flower food or bud-opening solution to get blooms to open.
Before arranging, rinse the stems under tepid running water and recut the stems on an angle, with a sharp, sterilised blade, removing at least 25mm (1in) of stem.
Depending on the stage of maturity Liatris have a vase life of six to fourteen days. Recut the stems and change the flower-food solution in their containers every two or three days.
To dry the flowers, cut when one-half to two-thirds of the flowers are open. Spikes can be air-dried by hanging them upside down in a protected spot for approximately three weeks or by using a desiccant such as silica-gel or sand, which often leads to superior colour preservation.


Garden Uses:
Cottage/Informal Garden, Prairie Planting, Borders and Beds, Wildlife Gardens, Flower Arranging.


Origin:
The genus Liatris is in the aster family, Asteraceae. It contains roughly 30 species that occur in almost every U.S. state east of the Rocky Mountains as well as in southern Canada and Northern Mexico. They hybridise freely so there are many populations of hybrid origin that complicates identification of plants. All have perfect flowers that are tubular shaped in discoid heads.
The species L. spicata grows in wet locations, naturally occurring in damp meadows and marshy places. The species produces magenta-purple flowers on 45 to 150cm (18 to 60in) tall spikes in August and September.


Nomenclature:
The meaning of the genus name Liatris has unfortunately been lost in antiquity.
The species name spicata comes from the Latin spica for spike. so 'with flowers in spikes' describing the elongated inflorescence, with its crowded, stalkless flower heads.
The protruding styles give the flower an overall feathery appearance, hence its common names of Blazing Star and Gayfeather.
The species is commonly called Snakeroot, Backache Root, Throatwort and Colic Root which refer to Native American medicinal uses as intestinal antispasmodics.
