Family name
Daviesia ulicifolia
Gorse Bitter-pea
(syn. D. ulicina)
Other Names: Native Gorse
Name Origin:
Daviesia — after botanist the Rev. Hugh Davies (1739-1821).
ulicifolia — ulex-leaved. Ulex is spiky European gorse or furze, which the ‘leaves’ of this species resemble.
Regional Subspecies:
D. u. subsp. aridicola, D. u. subsp. ruscifolia, D. u. subsp. ulicifolia
Occurrence:
Regional:
Noted in the areas: Burrumbuttock-West Hume; Upper Adelong & Upper Yaven, and Gocup. Possibly also in similar country in areas surrounding those noted.
Australia:
Qld, NSW, Vic, Tas, SA, WA.
Habitat:
Usually dry sclerophyll forest.
Habit:
Broadly spreading, much-branched stiff shrub to 2 m high. Narrow pointed dark-green ‘leaves’, 5-20 mm long.
Site Preference:
Dry, well-drained soil in semi-shade. Accepts moist well-drained soil in full sun. Resents poor drainage. Tolerates drought.
Characteristics:
Not grazed by livestock due to its thorns. Hardy.
Flowering:
Yellow and red-brown, Aug (low altitude) to Dec (high altitude). Pea-like.
Seed Collection:
Early Nov – late Jan. Monitor very closely as seed released immediately or within 1-2 days of maturity. To ensure collection, cover fruiting branches with nylon stockings or paper bags after flowering. Ripe pods are light-brown and brittle and rattle when shaken, with dark-coloured seed inside. May be difficult to obtain seed in useful quantities. Long storage life.
Propagation:
From scarified seed. Soak in near-boiling water for about 30 seconds, before cooling rapidly under flowing cold water. Alternatively soak in cold water for several hours. Dry to prevent rotting, before sowing. Germination occurs in 3-4 weeks. Suitable for direct seeding in pots (2-3 seeds per pot).
Regeneration:
From seed, particularly after fire.
VALUES:
Shade & Shelter:
Useful low-level cover in windbreaks.
Land Protection:
Useful understorey in recharge plantings, and for improving soil fertility, through ‘fixing’ nitrogen.
Wildlife:
Good habitat. Flowers are a pollen and excellent nectar source for various native insects and birds. Prickly foliage good refuge for small birds.
Ornamental:
Ornamental for barriers and under trees. Richer flower-colour than other Daviesia species. Prune severely to promote new, dense growth. Hardy in cultivation.
