About Cape Gold Everlasting

Helichrysum splendidum · also called Cape Gold Everlasting, Cape Gold · flowering

Helichrysum splendidum is a bushy, rounded, evergreen shrub native to rocky fynbos, grassland, and mountain savanna habitats along the eastern escarpment of Africa, from the Southern Cape of South Africa north to Ethiopia and Yemen. It is grown for its intensely silvery-grey, woolly foliage and bright golden-yellow, button-like everlasting flowerheads produced in late summer and autumn. Excellent drainage and full sun are the non-negotiable requirements; it is susceptible to root rot in heavy, wet soils. Helichrysum splendidum is not listed by the ASPCA; classified here as mildly-toxic on precautionary grounds.

Preferred mix: Poor to moderately fertile, neutral to alkaline, sharply drained

Watch for — Root rot in wet or heavy soil: The leading cause of death in cultivation; blackened roots and wilting foliage in moist soil indicate fungal root infection. Plant in raised beds with added grit and improve drainage before symptoms worsen.
