Meryta latifolia is a rare evergreen tree from Norfolk Island with very large leaves and separate male and female plants. It is grown mainly in warm, frost-free climates, where it needs shelter from wind and room for its big leaves.

About

Meryta latifolia, commonly known as broad-leaved meryta or shade tree, is an evergreen tree endemic to Norfolk Island, Australia, where it occurs in subtropical moist forest conditions.

How to grow it

Rare in cultivation, M. latifolia may be grown fairly easily in warm frost-free climates like those of Sydney, Australia, or Florida in the United States. A slightly hardier alternative is the New Zealand Puka tree, M. sinclairii, with huge broad leaves, which can withstand frosts down to -2C once established.

Where it grows

Meryta latifolia occurs only on Norfolk Island, and is considered critically endangered because it is dioecious, having separate male and female plants. The total number of mature individual plants is less than 150, the effective reproductive population limited by the number of surviving female plants, which number approximately 20. It occurs on ten sites on Norfolk Island, but most of these contain only one or two plants and only one site has more than 13. Although one site contains approximately 115 trees, regeneration is not occurring at this site. Continuing declines in the number of mature individuals, and number of locations and subpopulations are projected for several reasons including: lack of formal protection or management programs, the vulnerability of small populations to stochastic disturbance events (e.g. cyclones), ongoing competition with invasive weeds, predation by rats, senescence of over-mature plants, and sex ratio bias.
