Propagation of Dentaria Laciniata Muhl. ex Willd. var. Integra (O.E. Schulz) Fern.
Dentaria laciniata Muhl. ex Willd. var. integra (O.E. Schulz) Fern. or toothwort is a native plant of North America that belongs to the family Brassicaceae. It is commonly grown in gardens for its foliage and white flowers.
The propagation of Dentaria laciniata can be done through various methods, which are:
Seed propagation
Seeds from mature fruits can be sown directly in the ground during fall or early spring. The seeds should be kept moist until they germinate. The optimum germination temperature is between 5°C to 10°C and takes about 2-4 weeks to germinate. The seedlings can be transplanted when they are large enough to handle.
Vegetative propagation
Dentaria laciniata can be propagated vegetatively through rhizome division. The rhizomes should be dug up during fall or early spring, and the growing points should be separated and replanted. The new plant should be watered well after planting.
Cuttings
Stem cuttings can be taken from a mature plant, and the cuttings should be a few inches long. The lower leaves of the cuttings should be removed, and the cuttings should be planted in a mixture of sand and peat. The cuttings should be watered and kept in a cool and moist environment for 2-3 weeks. The cuttings should root in about 3-4 weeks and can be transplanted when they are large enough to handle.
In conclusion, Dentaria laciniata Muhl. ex Willd. var. integra (O.E. Schulz) Fern. can be propagated through different methods, such as seed propagation, vegetative propagation, and stem cuttings. Gardeners can choose the most convenient method according to their preferences and expertise.
