Botanical species in the genus Dalea recorded in the PlantPeers database.
Dalea aurea
Dalea aurea
Family: Fabaceae
Cultivation
This species has a symbiotic relationship with certain soil bacteria; these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby.

Dalea compacta
Family: Fabaceae
Cultivation
This species is closely related to Dalea purpurea and sometimes hybridizes with it in the wild. Although many species within the family Fabaceae have a symbiotic relationship with soil bacteria, this species is said to be devoid of such a relationship and therefore does not fix atmospheric nitrogen.

Dalea foliolosa
Family: Fabaceae
Cultivation
Dalea foliolosa is found wild from the temperate highlands of northern Mexico to the tropical regions at lower elevations from Mexico to Guatemala and Honduras. The crushed foliage has a strong smell of lemon balm (Melissa officinalis). This species has a symbiotic relationship with certain soil bacteria; these bacteria form nodules on the roots and fix atmospheric nitrogen.

Dalea formosa
Family: Fabaceae
Cultivation
At its altitudinal limit in southern Colorado and adjoining New Mexico, this species must endure zero temperatures and deeply frozen ground - conditions that no related species in the genus can tolerate. Although many species within the family Fabaceae have a symbiotic relationship with soil bacteria, this species is said to be devoid of such a relationship and therefore does not fix atmospheric nitrogen.

Dalea lanata
Family: Fabaceae
Cultivation
Requires a sunny position. Found in the wild only on sandy soils. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen.
Full cultivation guide →Dalea nana
Dalea nana
Family: Fabaceae
Cultivation
The variety nana is generally found on neutral to acid soils, it avoids rocky subsoils and is prevailingly calclfuge. The variety carnescens is calcicole, being found on limestone rubble, caliche, or gypsum. This species has a symbiotic relationship with certain soil bacteria; these bacteria form nodules on the roots and fix atmospheric nitrogen.

Dalea purpurea
Family: Fabaceae
Cultivation
Dalea purpurea is a very cold-hardy plant, tolerating temperatures down to below -20°c. It grows best in regions with a mean annual rainfall in the range 400 - 500mm, but can tolerate 300mm. Requires a well-drained soil in full sun.

Dalea villosa
Family: Fabaceae
Cultivation
Dalea vilosa is found from the cold prairies of southern Canada, where it can experience months of deep snow, to the warm temperate coastal plain of the southern USA. It is known to thrive in areas where the mean annual rainfall is around 300mm. Requires a sunny position growing best in deep, well-drained sandy soils but also growing well on silt-loam soils.
