Bryophyllum sp. (CRASSULACEAE) Mother-of-millions

Weeds to Whack

A fleshy (succulent) perennial with erect stems growing 30-120 cm tall, native to southern Africa. Introduced as an ornamental, now a widespread weed of untended areas such as waste ground, roadsides, pastures and spare allotments. The stems are rigid, upright (erect) and a greyish colour. Leaves are cylindrical with a lengthwise (longitudinal) groove. There are a few ‘teeth’ at the leaf tip (apex). Stems and leaves have a dark mottling and plantlets form in the marginal notches of the leaves. Fowers are tubular ‘bells’ (2-3 cm long) that are either orange-red or pink in colour. They are drooping (pendulous) and grouped into tightly branched inflorescences at the ends of the stems. Flowering occurs mainly during winter and spring.

Two Taxa

This image shows two taxa. Mother of millions Bryophyllum delagoense on the left and hybrid mother of millions Bryophyllum x houghtonii on the right. Both are likely to be found in our area. Mother of millions contains heart toxic compounds similar to those in cane toad venom. Toxicity is often prolonged (6-7 days). The major clinical manifestations are heart rhythm disturbances, high blood potassium levels, nausea, vomiting and visual disturbances.
