This fairly large Impatiens species comes from the Himalayas and the seed is winterhard. It is an annual, but will come back each year, but only if the seeds have been exposed to frost, so do not try to grow it in a warm greenhouse. It will grow in most types of soil and will produce white flowers.

This species comes from Sulawesi; it grows and flowers well and it is one of the first to start flowering in the new season; an ideal plant for the collector. In the wild it clambers through the trees. Assuming you do not have a tree in your greenhouse or house to support it, you can grow it as a hanging plant. The stems will grow to more than a meter, so give it enough space. Because it is very free-flowering, it attracts moths in the greenhouse which is good for pollination. One ‘problem’ if you have more hoyas around, the seedling could very well turn out to be a hybrid as cross-pollination is likely. You always get viable seed, though, which should be sown as soon as possible. Fresh seed will germinate 100 per cent, but if kept too long, the germination is drastically reduced.
The flowers are similar to Hoya brevialata, another species from Sulawesi, but on the 7752 they have a reddish colour while those of brevialate are white.

This species of Impatiens comes from the Himalayas in Pakistan; it is an annual species and is propagated by seed. It is not yet freely available in Europe, but I will try to build up stock and hope to offer it in my webshop in a couple of years. In the mean time, you can enjoy the picture.
