Double Trouble Sneezeweed

Double Trouble is an upright, clump-forming Helenium with ruffled double yellow petals around a golden center. Its patent describes a moderately vigorous plant about 75 cm tall and 46 cm wide; the Royal Horticultural Society describes plants to about 80 cm, and flowering references place its display from midsummer into early fall.

The long flowering season and clear yellow color make it useful in late-season groupings. ## Growing Conditions Give it full sun and fertile, moisture-retentive soil that drains freely. Keep the root zone from drying during summer heat. Divide established clumps every few years if flowering or vigor declines. ## Maintenance Deadhead faded flowers to prolong bloom. Tall stems may need support in exposed or windy sites; cut old stems back after flowering or in early spring.
