Propagation of Senecio atropurpureus var. dentatus
Senecio atropurpureus var. dentatus, commonly known as purple ragwort or rocky mountain ragwort, is a species of flowering plant in the Asteraceae family. It is native to North America and is found growing in rocky soils, mountain slopes, and open forests.
Propagation Methods
The plant can be propagated through seeds, cuttings, and division.
Propagation through Seeds
Senecio atropurpureus var. dentatus produces small seeds that can be collected in the fall when the flowers turn brown. The seeds should be sown in a well-draining potting medium and kept moist.

Propagation through Cuttings
Senechio atropurpureus var. dentatus can also be propagated through stem cuttings. The cuttings should be taken in the spring or early summer, when the plant is actively growing, and should be about 4-6 inches long. They should be planted in well-draining potting medium and kept moist. The cuttings will root in about 4-6 weeks and can be transplanted into individual pots.
Propagation through Division
Division is another way to propagate Senechio atropurpureus var. dentatus. The best time to divide the plant is in the spring or fall when it is not actively growing. The plant should be lifted carefully from the ground and the root clumps should be divided using a sharp knife or garden shears. Each division should have several shoots and a good root system. The divisions can be repotted in well-draining potting medium and kept moist until they are established.
