About:

P. tetrapetala is a notable parasitic shrub capable of reaching a width of up to 2m across. This intriguing plant typically establishes itself as a parasite close to the trunk of its host tree, drawing nutrients and sustenance from it. It features distinctive small, raised blisters or lesions on its small, generally rhombic-shaped leaves, which add to its unique appearance. The flowers of P. tetrapetala are often found either solitary or grouped together in clusters of 2 to 4, showcasing a vibrant bright red colour that can grow up to 40mm in length. As the plant matures, the ripe fruit develops into a fleshy and green structure.

Natural habitat:

Coastal to montane. A hemiparasite whose main hosts are mountain beech (Fuscospora cliffortioides), black beech (Fuscospora solandri), red beech (F. fusca), and silver beech (Lophozonia menziesii). However, it has been recorded as a parasite on a further 17 species (2 exotic) including puriri (Vitex luceans) and pohutukawa (Metrosideros excelsa).

How to grow:

Can be grown from fresh seed placed on suitable host tissue (ideally Fuscospora cliffortioides). Although seed germinates readily the ability of the seedling to form a firm host is rather variable. Failure rates are high and experimentation with plenty of fresh seed is usually needed.

** Seed germinates without pre treatment. Sow seed direct & keep moist until germination is complete.
