brighamia insignis belongs to the campanulaceae family and is endemic to hawaii. this means it’s the only place where it is found. it has a succulent stem with leaves forming a dense rosette at the top. it’s an endangered species, commonly known as hawaiian vulcan palm, Ã¤lula, olulu or sometimes cabbage on a stick.
brighamia insignis does best if located from bright with some morning and/or evening sun to light shaded. if placed outside during summer it should be protected from afternoon sun.
the hawaiin vulcan palm needs a well drained soil. i’m using a mix of loam free garden soil, coarse sand and pumice (2:1:1). but it also grows in a regular cactus mix.
it can be deep watered, what’s flowing out of the pot should be removed after a few minutes. wet legs can cause rotten roots. before adding water next let the soil moderately dry.
a half diluted cactus fertilizer can be given monthly in spring and summer and every six to eight weeks during fall and winter. recently repotted plants don’t need to be fed for the first six to eight weeks.
brighamia insignis has to be cultivated at room temperature the year round and needs a winter minimum of 15 °c/59 °f.
a high humidity is welcome and it likes to be sprayed over with water every day. alternatively it can be placed near a humidity tray. this may also protect it from spider mites.
the hawaiin vulcan palm can be propagated with seeds.
