Crassula columnaris

Crassula columnaris is a small succulent from South Africa and southern Namibia. It forms short columns of tightly stacked, cupped leaves and ends in a dense head of fragrant flowers. It grows mostly in winter-rainfall karoo and Namaqualand country, so it needs bright light, water in the cool season and a dry summer rest.
