Native blackthorn

Bursaria spinosa

Description.
A large, many-branched shrub to 4 metres in height (though larger, tree-like forms are known). Leaves are small (usually 3-4 centimetres long) and oval-shaped. They are generally smooth but may be hairy underneath. Branches have large spines at intervals. Flowers are creamy-white and produced in clusters at the ends of the branches. They are highly valued by insects. Flowers are followed by purse-like fruits which turn dry at maturity and open at one end, discharging the small, round, flattened seeds.
Propagation.
Seed germinates well without pre-treatment. Also from cuttings.
Flowering.
Known as ‘Christmas Bush’ in some areas for its habit of flowering in mid- and late-December. Occasionally November or January.
Locations.
Willans Hill. Occurs as scattered plants or small groups on roadsides west of Wagga Wagga, e.g. Millwood Rd, Pine Gully Rd. Very common near Henty.
