Maintenance of the Hawaiian Palm (Brighamia insignis) - Houseplant

Contrary to what its current name indicates, the Brighamia insignis is not a palm tree but a herbaceous plant part of the succulents. Obviously, our climate has turned it here into a houseplant or veranda since the temperature must not fall below 8 to 10° C. The Hawaiian palm is an easy crop but slow growing!

It has a swollen caudex at its base, gray in color with scars, then rises straight up and ends in a tuft of rosette leaves. The deciduous leaves are shiny pale green, obovate in shape, convex and leathery, with very pronounced veins. They measure between 15 and 30 cm long and 8 to 12 cm wide. Latex can come out of the trunk when removed.

In winter, the Hawaiian palm can offer 5-lobed, lightly scented yellow tubular leaves. Without pollination, it does not give fruit.

In Hawaii, it has become a protected species: indeed the moth which is its only pollinator has disappeared, which compromises its reproduction. On the other hand, with an artificial pollination, it invades today the gardening and other decoration stores, in France!
