Compact, easy care and drought tolerant, Blue Storm is one of the Storm™ series of agapanthus that produce more flower stems than any other agapanthus. In fact, Blue Storm flowers on average 10 weeks per season (up to two to three weeks longer than most other varieties).
When mature, within 3-5 years, this vigorous plant bears up to 100+ stems topped with spheres of soft violet blue flowers per plant per season - all bursting forth together to create masses of long-lasting blue blooms.
Blue Storm™ grows up to a compact 30 inches (2 ½ feet), an ideal height for landscapes and container plantings, as most other agapanthus are either much taller or shorter.
Agapanthus is increasingly popular with gardeners and landscapers for its easy-care nature, crisp exotic look, and long-lasting flowers. With its lush tufts of dense strappy leaves, the plant adds flair even when not in bloom.

Number Of Flowers
Approximately 25 stems, each with a flower umbel of up to 30 florets each on a 2 to 3 year old plant, 50 stems and umbels on a 4 year old plant and up to 100 on a 5 year old plant.
Umbellate of blue flowers.
Dense leaves are arranged in a tuft or cluster. Each leaf is narrow and strap-like, measuring on average 14 inches long by ¾ inches wide.
Remove dead flower stems after flowering in late fall.
Grows in most light conditions. Flowers best in full sun but will flower in reduced numbers in partial shade.
Blue Storm™ will tolerate a range of soils from sand to clay.
Water well to establish. But once established in the landscape, agapanthus are tolerant of both wet and dry conditions and have proved to be an ideal landscape plant for drier warm or tropical areas.
Promote initial growth by providing high nitrogen fertilizer for initial growth, but once established use a flowering plant formula high in potassium to encourage flowering.
Agapanthus are not prone to disease in the landscape.
No major pests. Snails and slugs may cause slight damage.
Easy-care plant. Initially, better performance will be attained if plants are watered and fed regularly, but once established Blue Storm will flower readily with minimal care. In colder zones, either winter protect, dig and store, or store potted plants 'as is' in a frost-free location.
Good plant for dry, sub-tropical areas. Thick, moisture-retentive foliage makes agapanthus effective in fire-retardant borders.
