There are numerous varieties and different breeds of bitterroot. Some of them are hardy and tolerate temperatures down to - 20 °C, while others are very sensitive to cold. However, very few of them are very durable.
Bitterroot (Lewisia cotyledon) is considered hardy
The Lewisia cotyledon is considered hardy and tolerates partial shade. It is ideal for dry stone walls or rock gardens. Other varieties flower more in red or purple tones or wither after flowering. Hybrids are often commercially available. The porcelain rosette, another name for bitterroot, is easy to care for and easy to propagate, as it forms daughter rosettes.
Wintering of young plants
The young plants of the hardy varieties are sometimes quite sensitive to frost. The roots, which are still tender, do not tolerate prolonged moisture well. Wintering in a frost-free and relatively dry environment is therefore advisable. In this way, the sensitive plants can continue to be supplied with water according to their needs without fear of root rot. From April, the strong young plants can then be planted outdoors.
The wintering of potted plants
You can overwinter potted plants in a similar way to the young plants. Above all, it is important that your roots are protected from the frost, because if they freeze through, the plant will die. However, the biggest problem for bitterroot is persistent wetness, which leads to root rot.
If you have decided to buy a non-hardy variety of bitterroot, then plant it in a pot or bucket at least for the winter. Of course, you can also cultivate bitterroot in a planter all year round. With its low growth, it is ideal for balcony or terrace planting, but less so for the windowsill of your living room.
