Brunsvigia radulosa has a large bulb that is covered with hard brown tunics. It produces 4-6 leaves, usually present at or after flowering, spreading flat on the ground; large, very thick and tough with rough surfaces and margin. The species name refers to this roughness. The inflorescence consists of up to 75 flowers, individually stalked, forming a large umbel.
Brunsvigia radulosa is normally found in rocky outcrops and must not be overwatered. When in flower, it is quite spectacular.
Growth rate is very slow and it is more suited to pot culture.
