Botanical Name: Rhodiola rosea
Height: about 15 cm
Season of bloom: Spring. Plants are either male or female and the blooms appear at slightly different times (which is weird).
Growing Conditions: Full sun. Rock gardens and troughs. Drought tolerant when established but the plants bloom best with abundant spring moisture.
Wildlife benefits:
From Ottawa Valley or eastern Ontario sources: No. A circumboreal Arctic species which adapts to more southern gardens.
Seeds: Germination Code: A + cool. Seeds do not require any special pretreatment but germinate best in cool soil temperatures (about 10 C).
Remarks: The roots have an attractive floral fragrance. The roots have been used as an herbal tea and, apparently, to flavour vodka.
Similar species: Rhodiolas were once included with the Sedums.
