Description

Pyrrocoma is a genus of flowering plants in the sunflower family (Asteraceae) that consists of about 30 species. These plants are native to North America and are commonly found in mountainous regions, particularly in the western United States.

The flowers are often clustered at the tips of the stems and are surrounded by a ring of green bracts.

Taxonomic Information

Appearance

Pyrrocoma plants can range in height from 6 inches to 3 feet and have a bushy, clumping growth habit. The leaves are typically narrow and lance-shaped, with a slightly toothed edge. They are usually green, but some species have silver or gray foliage. The flowers are bright yellow and have a diameter of about 1 inch. They have a central disk of small, tubular flowers surrounded by several yellow petals. The flowers are often attractive to pollinators, such as bees and butterflies.

Care Guide

Pyrrocoma plants are generally low-maintenance and can be grown in a variety of conditions. They prefer well-drained soil and full sun, but can tolerate some shade. These plants are hardy in USDA zones 4-8. Watering should be done regularly, but not excessively, as Pyrrocoma plants do not like to be waterlogged. Fertilization is not necessary, but can help promote healthy growth. Deadheading the spent flowers can help encourage more blooms.
