Daviesia ulicifolia

Daviesia ulicifolia, commonly known as gorse bitter pea, is a small to medium sized Australian shrub, reaching two meters in size.[2] Its leaves may be oval or elliptical, and terminate in a sharp point.[2] Daviesia ulicifolia has yellow or red pea flowers, complete with keel, wings, and standard. Flowering occurs from August to December depending on altitude, with flowering occurring later in the season at higher altitudes.[3] The fruit is a pod, and is usually formed between September and January.[3]

Habitat, Distribution and Ecology

Daviesia ulicifolia is a drought tolerant shrub, commonly found in dry sclerophyll forests in most of Australia.[2] These forests tend to undergo bushfires every four to twenty years.[4] A bushfire can remove over 70% of the available nutrients from the soil. Plants that exist in areas of frequent bushfire are often adapted to growing with low levels of nutrients. Daviesia ulicifolia, like many Fabaceae, can grow in soils with low levels of the nutrient nitrogen, by forming the symbiosis of nodulation with nitrogen fixing bacteria.[5] This promotes the growth of Daviesia ulicifolia in soils with low nitrogen as well as accumulating nitrogen into the ecosystem, restoring part of the nitrogen lost in previous bushfires. Daviesia ulicifolia is also a nesting site for small birds.[6]
