Portulaca molokiniensis, known also as 'ihi, is a succulent plant endemic to Hawaii. It branches from the base to form a small shrub up to 12 inches (30 cm) tall. It has small yellow flowers and when grown from seed may produce a caudex.
Portulaca molokiniensis is a stout, upright growing succulent that branches at or below the soil line to form a small shrub to 30 to 50 cm tall by about as wide with each stem being about the thickness of a cigar. It bears 2.5-5 cm long rounded pale green succulent leaves that are arranged neatly in 4 distinct rows towards the branch tips. A cluster of small yellow cup-shaped flowers forms at the ends of thick stalks that arise from the centre of the leaf rosettes, but it is the foliage of this plant that really makes it unique. Portulaca molokiniensis is an attractive plant for cultivation.
