Stem Agapanthus Overview
Agapanthus caulescens is a deciduous plant from the Amaryllidaceae family. It is reasonably hardy and typically grown for the attractive flowers. This plant forms short green leaves measuring between 25-60cm long. These give rise to a blue-violet ball of flowers on a long stem, around 60-180cm in height. Flowers are flared outwards, paler towards the base and have dark midribs. The leaves are strap-shaped and due to their short stature, this species has a leek-like look when not flowering. It's very similar in appearance to Common Agapanthus, Agapanthus praecox. This African Lily is more free-flowering than many Agapanthus species, producing a variable number of blooms per flowerhead.
Common problems with Stem Agapanthus
