The inflorescences arch out beyond the leaves and
carry insignificant, small white flowers and, eventually, very small,
white fruits, only a few millimetres in diameter. Thrinax is hermaphroditic
(the flowers have both male and female organs) and accordingly.
a single tree can produce viable fruits. As a genus, Thrinax is
closely related to Zombia, a clustering palm which is easily distinguished
by its spiny leafsheath fibres, and Coccothrinax, both native to
the Caribbean. It is often confused with Coccothrinax but can be
easily identified by its split petiole bases, white fruits (purple
to black in Coccothrinax) and smooth seeds (grooved in Coccothrinax).
In cultivation, Thrinax morrisii is by no means
common and will probably never become a commercial subject. It is
easily propagated by seed which germinates after a few weeks but
seedlings are very small initially and grow rather slowly. Nevertheless,
it is a beautiful and exceedingly robust plant, well worth growing
as an ornamental in warm temperate to tropical climates and a particularly
good choice for seaside plantings. It is successful in any area
with sufficiently warm summers and mild winters and will resist
brief frosts down to -5ūC undamaged, making it hardier than any
other species in the genus and most of its close relatives.
It can grow in a wide range of soil types as long
as they are well drained, tolerating even very poor and saline or
highly alkaline soils, arid stands lip well to coastal conditions
with high winds, salt spray and drought. When planting. choose a
place in full sun with buoyant air movement for best results. All
you need do now is wait. For those not blessed with a suitable climate,
it will also, like many plants from coastal areas, make a very good
house plant for a brightly lit spot, tolerant of dry air, temperature
fluctuations and a considerable amount of neglect, and is hardly
ever bothered by pests.
