Plant in full sun or light shade in coastal areas or light shade inland. Best with occasional summer water. Hypocalymma prefer acid to neutral soils but are tolerant of some alkalinity provided the soil has adequate drainage. It is cold hardy to 15-20° F and a nice garden plant that responds well to pruning. Its attractive flowers attract butterflies and makes it good for cut flower uses. The genus Hypocalymma is endemic to south-western Western Australia and Hypocalymma angustifolia has long been in cultivation in Australia and was first introduced into England in 1843. The name of the genus is from the Latin words 'Hypo' meaning "under" and 'calymma' meaning "covering" in reference to the cap of the calyx when in bud. The specific epithet 'angustifolia' means "narrow leaves".

This plant was a U.C. Santa Cruz Arboretum Koala Blooms Australian Plant Introduction in 2010 and we grew it from that year until 2015.
