It is a fast-growing, bulky species, but when grown it often looks visibly battered or tired. However, the plant will reward experienced gardeners with a ring of beautiful pink-purple flowers surrounding the crown of the plant. Several forms are known, some with golden spikes, some with red or black spikes. A large stem will grow towards the sun, changing direction in just a few weeks if the plant is turned over.
Flowers: purplish-red or pinkish-red, surrounding the crown of the plant, up to 17-20 mm long, 11-15 mm in diameter.
