Helenium bolanderi is a North American species of flowering plant in the daisy family known by the common name coastal sneezeweed. It is native to southern Oregon and northern California as far south as Mendocino County, primarily along the seacoast.Helenium bolanderi perennial herb sometimes as much as 140 cm (56 inches or 4 2/3 feet) in height. It has a generally unbranched, erect stem with oval-shaped leaves. The flowers arise on naked peduncles with one to three flower heads per plant. Each flower head has a fringe of 15-30 golden yellow ray florets bent backwards from a rounded center of sometimes over 1000 disc florets (yellow toward the base but brown or purple near the tips). The fruit is a tiny, hairy achene a few millimeters long.
How to keep Helenium Bolanderi.
Pruning
To boost the health and appearance of coastal sneezeweed, prune it early in the spring, cutting it back to 6 inches above the ground. This encourages better growth, improves air circulation, and reduces the risk of disease. Be sure to remove any damaged stems, but avoid heavy pruning during its peak growth period to prevent stress. This careful approach will encourage vigorous blooms after flowering.
