Ocimum kilimandscharicum x basilicum

Common Name(s):

Description

African Blue Basil is a sterile hybrid edible herb with showy leaves and beautiful flowers.  Because it does not produce seed, its flowers do not need to be pinched back to keep the plant growing like other basils.  It is grown as a pernnial in zone 10 and higher and as an annual in lower zones as it cannot tolerate frost.  Plant it in the full sun in moist well-drained soil.  Once established the plant can tolerate drier soils but it is by no means a drought tolerant plant. Some partial shade is tolerated in the afternoons in hot climates. This plant is more heat tolerant than other basils.  It has an upright habit that over time rounds out.  As the rapidly growing plant matures its stems may become woody and heavy sometimes flopping over.  Trim unwanted branches back and new growth will appear out of old stems.  

It does grow well in indoor settings more than other herbs.  Use it in a culinary herb garden, a sensory garden, or grown in containers.
