Agapanthus caulescens
stalked African lily
A deciduous species and reasonably hardy. The leaves are produced on a distinct stem, the basal sheathing leaves sometimes very short giving this part of the plant a leek-like appearance. Foliage is 25-60cm long, with flower stems 60-180cm. The number of flowers in a flowerhead is variable; the flowers are usually dark violet-blue, paler towards the base and with darker midribs; often widely flared
