Wild Bush Petunia
If you have never had the pleasure of seeing this plant in full bloom you are really missing something. It bears masses of large pale pink Petunia-like flowers in summer. The flowers emit a sweet fragrance at night and are moth-pollinated. They also produce copious amounts of nectar – attracting those fat Carpenter Bees to the garden, as well as a myriad other insects that feast on this bounty. These insects in turn attract insect-eating birds to the garden and, as it is fairly low-growing, they also provide food for frogs and lizards. The plant is spiny and has bright green leaves. As it only grows from 30 to 80cm tall it is a useful size and can be mass planted for a stunning effect.
B.greenii is a recently described plant and is thus quite rare in cultivation although it is exceptionally easy to grow. It is a very hardy plant that can tolerate quite extreme conditions. It should be planted in compost-rich soil, preferably in full sun as it will flower better, although it does tolerate partial shade. For a fresh flush of growth in spring and a beautiful display of flowers in summer, prune it back almost to ground level in winter.
