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 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.

Impatiens bicolor

This 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 can produce white or yellow flowers. If you consistently remove the yellow ones, you will, after only a couple of years, end up with just white ones. Seed available from my webshop.
