They have dense leaves arranged in a tuft or cluster, each leaf being narrow and strap-like, measuring on average 14 inches long by an inch wide. Storm agapanthus grows in freestanding basal clusters about 20 inches wide over large, thick, fleshy roots. Full height is achieved in 18 months.

Do I need to feed the Storm® series agapanthus?
They will perform and flower well under difficult conditions. However all plants, to achieve high performance need fertilizer to perform at peak levels. To promote initial growth use a high nitrogen (high first number) fertilizer, once established use a flowering plant formula high in potassium (high middle number) to encourage more flowers.
What about disease and pest issues?
Storm® agapanthus are not prone to disease in the landscape and they have no major pest issues.
Can Storm Agapanthus be used as a fire-retardant border?
Yes, the succulent foliage does not readily burn and so rows of closely planted Storm series agapanthus will act as a 'fire-break'.
