A few years ago, I found two interesting plants in a nursery, hiding below a desk, if only someone has left them there. I bought both of them. They spent the winter under outside conditions, but protected from the precipitation. In the spring I repotted them, and soon, they were flowering. Later on I was searching for these plants in the nurseries and this I obtained a few plants of different flower colours. On the next winter - the winter of 2015/16 - I wanted to test their winter hardiness, in a rock garden. All plants survived the wintertime; nevertheless, its winter hardiness is not complete in our country. The genus Lewisia was named in honour of its finder, Meriwether Lewis, from the US, in 1814. The name biterroot is not only applied for this taxon but to its entire genus, along with their medical usage. So far, I only met L. cotyledon in the nurseries. The flowering period starts in April, follows in May. According to fact literature data, the plants prefer the semi shade, but according to my experiences, they can tolerate the full sun pretty well. They require slightly acidic or neutral soil, a pH never higher than 7.0.
