YOU MAY HAVE HEARD that where poison ivy grows, jewelweed (Impatiens capensis) is a remedy that will grow nearby. But do you know about Rhodiola rosea? In mountainous parts of the world with severe winters, where humans struggle with the fatigue of rarified air and susceptibility to colds and flu due to the icy weather, this member of the crassula family often grows nearby and offers them protection against the harsh climate. And it might do so for you as well, even at more clement altitudes.
Rhodiola rosea-also known as golden root, Sedum rosea and roseroot, among other names-is related to succulents like the jade plant (Crassula), Sedum, Dudleya, Kalanchoe and Echeveria. It's a tough little perennial growing only about a foot tall, with yellow to green flowers in May to July. It has evolved on alkaline soils in conditions of little rainfall, freezing temperatures and the searing actinic sunlight of high elevations. To protect itself, it produces large amounts of phenolic compounds and vitamin C, substances that also heal, invigorate and protect humans and animals.
JEFF COX is a longtime Horticulture writer who gardens in California. In 2023, his column focused on specimen plants for their beauty in the garden or landscape. This year, the attention turns to potent plants with medicinal properties that might be handy to grow at home-if you can find them. Some are common, others obscure, and still others may have been lost for thousands of years but now have seemingly been rediscovered. All of them are plants you'll be grateful to have if you need them.

The best crops to plant throughout summer, plus how to time them right. Once a crop like spring turnips or snap peas has finished, I tidy up the bed, amend the soil with a thin layer of compost and replant. Depending on the new crop, I may be sowing seeds or transplanting seedlings.
