The blazing star ( Liatris spicata ), more spiked blazing star called, is a flowering plant in the family of the daisy family (Asteraceae). She comes from North America. Their varieties are planted in the temperate areas of the world as ornamental plants in parks and gardens and used as cut flowers . As soon as the perennial blooms, bees , bumblebees and butterflies visit it.
description
Liatris spicata grows as perennial herbaceous plants that usually reach heights of 40 to 110 (20 to 180) cm. They often form spherical to egg-shaped tubers and elongated rhizomes as persistence organs. The upright, hairless stems are usually unbranched or, less often, branched at the base. The alternate, sessile or stalked leaves are more or less grass-like with smooth leaf edges; they are 12 to 35 cm long and usually 4 to 10 (2 to 20) mm wide.
In large terminal annual total inflorescences, there are often many cup-shaped partial inflorescences that bloom from top to bottom. The unequal bracts are in (rarely three) usually four to five rows and their membranous edges are sometimes ciliated but not toothed. The flat inflorescence base has no chaff leaves. The flower heads, which are short stalked at most 1 to 2 mm, are 7 to 11 mm in length and usually 4 to 6 mm in diameter and usually contain only five to eight (four to 14) tubular flowers . The flowers petals are usually red to pink to purple, sometimes white. The corolla tubes, hairless on the inside, have a diameter four to six times smaller than their length.
The eight- to eleven-ribbed achenes are (3.5 to) 4.5 to 6 mm long. The long-lived pappus is more or less the same length as the crown and consists of bearded bristles in one or two rows.
The number of chromosomes is 2n = 20.
