Rhodohypoxis are small but colourful alpine perennials which make an unusual addition to many gardens. Peter Valder took a closer look at these small plants which are native to high altitude regions of East Africa.
Plant details
Common name: Red star, rosy posy
Botanical name: Rhodohypoxis baurii
Description: Rhodohypoxis are short, tufty perennials which grow only around 8cm (3″) tall with a similar spread. In their natural habitat they are often found on open grassy slopes in areas of high altitude. The bright green leaves are long and strap-like, and slightly hairy. Rhodohypoxis flowers are star-shaped and have six petals; the three smaller ones are arranged on top of the three larger ones. This plant flowers from late spring until autumn and comes in a range of colours from pure white to a selection of pinks and into the dark reds. One pink variety is sold as ‘Rosy Posy’.
Climate: Rhodohypoxis are fairly adaptable to low temperatures – down to -5°C – and will grow in all but the most tropical or hot parts of Australia.

The three inner petals protect the heart of the flower from inclement weather by folding together, but re-open when an insect lands on the flower.
