About Pyramid tree
Lagunaria patersonia, commonly known as 'cow itch tree', is a medium to large ornamental tree native to Australia. It is notable for its beautiful pink, hibiscus-like flowers that appear in spring and summer, and its seed pods containing irritating hairs (hence its common name). It is ideal as a shade tree, a specimen plant, or for avenues in warm and temperate climates.
Native range
Norfolk Island and Lord Howe Island, in the Southwest Pacific
Care tips
It prefers full sun and is very drought-tolerant once established, although regular watering during dry periods will promote better flowering. It adapts to a wide range of well-drained soils, including sandy or poor soils, and tolerates saline conditions. Avoid overwatering, as it is susceptible to root rot in waterlogged conditions.
