Variety description
10 August 2026
The plant reaches a height of 90–120 cm. The bush is dense and has a strictly vertical, columnar form. The foliage is narrow, light green, sometimes with a silvery-blue hue, and turns orange and reddish-brown in autumn. The stems are sturdy and maintain their shape well throughout the season and in winter.
Flowering begins in mid-summer. The airy panicles are initially grayish-white, turn purple by late summer and autumn, and then acquire a brown tan shade. The variety is warm-season, distinguished by high winter hardiness in zones 4–10, drought tolerance, and resistance to deer browsing.
Used exclusively as an ornamental crop for mass plantings, creating accents, and designing mixed borders and prairie-style flower beds. The plant requires minimal maintenance; pruning the aerial part to ground level is recommended in late winter or early spring before the active growth period begins.
