Propagation Methods of Ranunculus acris L. var. villosus (Drab.) S.M. Coles
Ranunculus acris L. var. villosus (Drab.) S.M. Coles is commonly known as hairy buttercup, and it belongs to the Ranunculaceae family. The plant is distributed throughout Europe, Asia, and North America. It is a herbaceous perennial that can grow up to 60cm tall. The plant has hairy stems and leaves, and it produces bright yellow flowers with five petals. Propagating Ranunculus acris L. var. villosus can be achieved through various methods.
Seed Propagation
One method of propagating Ranunculus acris L. var. villosus is through seed. The plant produces seeds in the summer, and they can be collected once they have matured. To increase the germination rate, the seeds can be stratified at 4°C for 4-6 weeks. Afterward, the seeds can be sown in a well-draining potting mix and kept moist. The optimal temperature for germination is around 15-20°C, and the germination period can take up to 4 weeks.
Division Propagation
Another method of propagating Ranunculus acris L. var. villosus is through division. The plant develops a root system with multiple crowns, making it easy to separate and transplant. The best time to divide the plant is in the spring when new growth is emerging. To propagate through division, the plant can be lifted from the ground and the root system carefully separated. Each division should contain at least two crowns and a portion of the root system. The new divisions can be replanted in a well-draining potting mix and kept moist.
Cuttings Propagation
Ranunculus acris L. var. villosus can also be propagated through cuttings. The best time to take cuttings is during the active growing season in the summer. Cuttings should be taken from healthy stems and should be around 8-10cm long. The bottom two leaves can be removed, and the cutting can be dipped in a rooting hormone powder. The cutting should be planted in a well-draining potting mix and kept moist. The optimal temperature for rooting is around 20-25°C, and the new plant should root in around 4-6 weeks.
