Description and Ethnobotany

Growth Form It is a sprawling, non-vining herb that grows up to 0.3 m tall, occasionally grown as an annual.
Foliage Its leaves are spoon to broad-lanced shaped, bluish green in colour. Fine hairs found on the leaf surface gives foliage a velvety texture. The leaves measure at 1.5 - 3 cm long and 0.6 - 1.5 cm wide, with a smooth margin and round tip.
Flowers Flowers are white, funnel-shaped, produced at the nodes (axillary). Despite lasting up to a day, this cultivar produce flowers freely.
Fruits Fruit is globose, produced in a capsule form measuring at 2 mm wide.
Cultivation For abundant blooms, position the plant under full sun condition (6-8 hours) grown in well-drained soil to prevent root rot. Once established, this cultivar is low-maintenance with a good tolerance for salt and short periods of drought.
Etymology The genus epithet derived "evolvo" meant to unwrap or unroll with reference to the non-vinning or twining branches present in many species of the family. The species epithet "glomeratus" refers to the grouped or gathered inflorescence.
