General Notes

This plant is weedy. We do not recommend planting it in Hawai’i.

The silver date palm is naturalized in a number of locations in Hawai'i, but particularly on the north shore of Oahu. This species is closely related to the Canary Island date palm (P. canariensis), but has a more slender trunk, and fronds that are shorter and more silver in color. The two can also form hybrids. Phoenix sylvestris has a HPWRA (Hawaii' Pacific Weed Risk Assessment) score of 17 (High Risk).

Native to Southern Pakistan, India, Sri Lanka, Nepal, Bhutan, Burma and Bangladesh.

Trees may be referred to as male or female.
