Barleria obtusa is multi-stemmed shrublet with a sprawling habit. The branches have an erect or decumbent habit. The size of the plant varies when planted in different growing environments. From about one metre as a low bushy plant in the open, whilst shady conditions encourage long sprawling branches which reach a height of two metres.

This fast growing, spreading shrublet is a must for rockeries and small gardens.

Barleria obtusa occurs naturally from the Soutpansberg in the Northern Province, Mpumalanga, and KwaZulu Natal and further to the Eastern Cape Province. It grows quite commonly on hills, in bush and along forest margins in subtropical regions.

Regular pruning is necessary after the shrub has flowered, for neat and compact growth. To encourage more flowers, nip off the shoots during spring and early summer.

The soft, sage green leaves are oppositely placed and have entire margins with fine translucent hairs. A characteristic feature is that the leaves are reflexed (the margins are upturned).

The 20-30 mm wide flower petals are borne on the top part of the branch. A closer look at the individual flower will reveal the style and only two stamens with violet coloured pollen. Flowers are blue or pink.
