Common Name:

Trachycarpus wagnerianus is listed separately here, though most palm experts include this within Trachycarpus fortuneias a Japanese cultivar, despite its rather striking differences, at least in cultivation. This is a nearly equally hardy palm as T fortunei, but it slower growing and smaller all around. The most notable difference is the leaf size (about 1/2 to 1/3 the size) and stiffness (very little droop of these leaves). Also this palm seems to want to start out life growing at an angle so it is not unusual seeing smaller palms curve at the base. However, eventually these palms straighten themselves out. They have less trunk scurf but color and flowers are identical to those of Trachycarpus fortunei generally.

Appearance and Biology

Habit: single trunk with a head of about 20-30 fan leaves
Height: 20'
Trunk: solitary; covered with dark brown fibrous material and retained, unspilt leaf bases; if cleaned, trunks to have closely space rings that lose their distinction with age; about 6" diameter
Crownshaft: none
Spread: 4'-6'
Leaf Description: 3' long (including petiole); stiff with minimal droop/sag; leaflets very stiff with minimal to no arch or droop at all; palmate leaves about 1' long and wide; semicircular; leaves divided from 1/2 to 2/3 their length; induplicate leaflets, often with splitting tips; dark green turning bright yellow at leaflet bases; almost plastic-like
Petiole/Leaf bases: 2' long; thin and somewhat flattened; either smooth or armed with very tiny, closely spaced teeth; dark green
Reproduction: dioecious
Inflorescence: see Trachycarpus fortunei
Fruit: 1"; black; spherical
