<i>Allium </i>plant named ‘Pincushion’

Abstract

A new and distinct cultivar of Allium plant named Pincushion, with glaucous, upright, stiff, strap-like, slightly-twisted green foliage, and numerous, tightly-clustered, light lavender-purple flowers forming in densely-arranged globose umbels over a long period beginning in early August. Strong stems hold the flower heads upright through flowering and seed production. The new plant is deer and rabbit-resistant and makes an attractive plant for the garden.

Claims

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The photographs of the new plant demonstrate the overall appearance of the plant, including the unique traits. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, source, and direction may cause the appearance of minor variations in color.

(2) FIG. 1 shows the side-view habit of a three-year-old plant in early flowering.

(3) FIG. 2 shows a close-up of the umbels with flowers and buds.

DETAILED BOTANICAL DESCRIPTION

(4) The following descriptions and color references are based on the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. The new plant, Allium Pincushion, has not been observed under all possible environments. The phenotype may vary slightly with different environmental conditions, such as temperature, light, fertility, moisture, and maturity levels, but without any change in the genotype. The following observations and size descriptions are of a three-year-old plant in a trial garden of a wholesale perennial nursery in Zeeland, Michigan under full sun with supplemental water and fertilizer as needed.
