ARS Victoria Newsletter – October 2019
This species comes from Yunnan and Szechwan in the Himalayas at 2700 to 4900 metres and is common where few other plants can grow. It is generally less than 30 cm. high. It is an excellent rockery plant at Olinda but does not survive long in Melbourne suburbs during our hot summers. It is often confused with R. tapetiforme which has smaller leaves and deeper blue flowers, at least with the clones we have. R. impeditum can be seen flowering in the main rockery around early October.
