Growing Notes

Thrives in cool marine influence areas of coastal California, even through the drier areas of Southern California.
Palms are generally heavy feeders, so if you want them growing quickly and looking their best, they should be fertilized at least three times a year. Fertilizing at spring equinox, summer solstice and fall equinox will allow for a winter rest. Be sure to feed your palm with a fertilizer that contains micronutrients (especially including magnesium), especially if you see yellowing leaves or yellow spots on the leaves.
Will not grow in interior California as this palm is intolerant of dry heat.
Young plants appreciate shade and can be cooked quickly in full sun. Mature plants do well in full coastal sun.
Adaptable to various soils, but prefers well drained soil.

Special Interest

Since this palm has almost no petioles (leaf stems) its crown resembles a shaving brush, thus the second common name for this tree - the shaving brush palm. This also means that the crown is both very full and also narrow, fitting into surprisingly tight spots.

Plumed amethyst flowers emerge below leaf sheaths, followed by red fruit.

It is reported that the Maori traditionally ate the young inner leaf shoots and also immature flower clusters. They also used Nikau leaves for thatch.

This palm is the most southerly growing palm on earth!
