Useful plants

Wood, fibre, shelter and craft

Date palm

Phoenix dactylifera

Useful plants

Identify: Feather leaves with spiny basal leaflets; single trunk; large hanging clusters of oblong dates.
Habitat: Oases, irrigated valleys and hot arid settlements.
Season: Fruit late summer-fall; fiber year-round.
Field use: Ripe dates are high-energy food; leaflets and midribs provide weaving, thatch, cordage and splints.
Caution: Feral palms may be chemically treated or privately owned. Spiny petioles injure.
Look-alikes: Canary Island date palm has shorter, bulkier fruit and denser crown.

Aquatic edibles

Water-margin food species

Cattails

Typha spp.
