Aloe "Vroegjaar Geel"

The first inflorescences of this extremely long-flowering aloe cultivar can open as early as January (midsummer in SA)

and some of the plants will not be without flowers until the end of winter. It can also surprise the gardener with a massive display of simultaneous inflorescences in winter, as pictured in the photo. The flower buds are yellow and the open flowers tend to be a shade or two paler.
