Propagation of Lobelia kalmii L. var. strictiflora Rydb.
Lobelia kalmii L. var. strictiflora Rydb. is a perennial plant species that produces beautiful blue flowers. Propagation of this plant can be done in several ways, as described below:
Seed propagation
Propagation through seeds is the easiest and most common method for Lobelia kalmii L. var. strictiflora Rydb. Seeds can be collected from mature seedpods and sown in well-draining soil. The best time to sow seeds is in the early spring, and the seeds should be placed at a depth of one-eighth of an inch. The seeds need to be kept moist, and should be germinated within 21 days. Once germinated, the plants can be transferred to individual pots and then transplanted into the garden once they are strong enough.
Division propagation
Propagation through division is another viable option for Lobelia kalmii L. var. strictiflora Rydb. This method involves taking a mature plant and dividing it into several parts. The best time to divide a plant is in the early spring or fall. Each divided part should contain a strong stem and roots. These parts can then be replanted in separate locations, and will develop into a new individual plant.
Cutting propagation
Propagation through cuttings is a third method for Lobelia kalmii L. var. strictiflora Rydb. Cuttings can be taken from the stems of a mature plant, preferably from the stem tips. A stem cutting should include two or three leaf nodes, and should be at least three inches in length. The bottom inch of the cuttings should be dipped in rooting hormone, and then planted in compost-rich soil. The cuttings should be kept moist and in a warm location, and should develop roots within a few weeks. Once rooted, the cuttings can be transferred to individual pots and then transplanted into the garden once they are strong enough.
By utilizing these propagation methods, it is possible to propagate Lobelia kalmii L. var. strictiflora Rydb. and enjoy its beautiful flowers year after year in your garden.
