Liatris, gay feather

Description / Shipment / Storage / Risk factors

Scientific Name and Introduction

Liatris pycnostachya, L. spicata. The specific epithet pycnostachya means thick-spiked in reference to flowers while spicata means spike.
L. spicata is the taller of the two species. Native to prairies of North America, liatris was developed as a cut flower in Israel. The bright purple spikes provide interesting texture and line in arrangements, and can open fully if properly treated after harvest.

Quality Characteristics and Criteria

Liatris spikes should be harvested with no more than 25% to 33% of the flowers in the spike open. They may be harvested with only the top buds showing colour and will open fully if provided with an effective preservative. Liatris responds best when about one-quarter to one-third of the flowers are open. However, if preservative solution is properly used, flowers can be harvested with no colour showing and subsequently opened.

Grading and Bunching

Quality Liatris flowers are of proper maturity (no more than one third of the flowers on the spike open), are free from defects and damage, and have good quality foliage. They are normally bunched in groups of ten and sometimes sleeved.

Ethylene Sensitivity

Liatris flowers are not affected by exposure to ethylene.

Pretreatments

Pulsing with preservative containing additional sugar (10 to 20%; about 100 gr of sugar per quart or litre of water) will improve opening of tight-cut flowers.

Storage Conditions

Store Liatris at 0°C to 1ºC.

Packing

Liatris are normally packed in horizontal fibreboard boxes, but may also be packed in hampers.

Special Considerations

Be careful of fungal problems such as Botrytis (especially for those grown outdoors) as well as water stress. Leaf yellowing and reduced life are common when these problems exist and are not easily controlled. Using preservative solution helps open more flowers per stem, but doesn’t make individual flowers last longer. A member of the Asteraceae (chrysanthemum or aster family), this species is also unusual in that flowers open from the top of the stem downwards; delphinium, gladiolus, snapdragon, and most other spiked-type flowers open from the bottom up.
