The Rhodioloa rosea, or rose root, is a hardy perennial that is not frost tender. It is hardy to Zone 1. This plant is not self-fertile, so it needs a male and female plant to propagate via seed. Bees and flies pollinate the plants. The planting spot must be chosen carefully---the Rhodiola rosea does not like the shade but will grow in most types of soil, to the point of tolerating drought in some areas. It also tolerates salty climates.
Choose a sunny spot that is raised. If the spot is not raised, you can use a raised bed to grow Rhodiola rosea. Dig a planting hole as deep as the root ball and twice the width of the root ball.
Center the Rhodiola rosea in the planting hole. Backfill the planting hole with soil. Water with 1 inch of water. This plant prefers drier soil and is drought tolerant after it becomes established. Water the Rhodiola rosea every week and a half with 1 inch of water. If you notice wilting, water every eight or nine days instead of every week and a half.
Pull the suckers if you do not want the rose root plant to spread. The Rhodiola rosea can become a nuisance if left alone.
Prune the Rhodiola rosea in the spring for dead and decaying plant matter. Prune the plant throughout the growing season for excessive foliage as needed.
