Hardenbergia violacea Mini HaHa

Position. Full sun, by South Australia's Plant Selector, which lists it for second-line coastal sites, coastal footslopes, plains, footslopes and hills.

Soil and water. A loam soil, acid, neutral or alkaline; the Plant Selector lists lime and drought among what it tolerates, with minimal supplementary water.

Frost. The Plant Selector lists moderate frost among what it tolerates.

Habit and pruning. The Plant Selector lists its habit as dense, spreading and vigorous, and its form as a low shrub. The notes on its entry, word for word the same as the notes on the Plant Selector's entry for the species, say that it responds to hard pruning, which improves its shape, and that it can be trained to climb. No other reference read describes how this form grows.

Massed, it makes a cover for the ground or a fence, and singly it suits roundabouts, broad verges and mixed beds: so say the Plant Selector's notes for this entry, which repeat its notes for the species. The same notes say it attracts native butterflies and is a food source for caterpillars, and the entry lists habitat, ornament and screening as its purposes. Worked from its 0.8 to 1 m spread, plant at about 0.8 m centres for a cover that closes over. Another named form, Meema, has its own page, and the wild plant is on the species page.

Lists spell the name several ways, Mini HaHa, Mini-Haha and Mini Ha Ha; check you are comparing the same plant.
