Pruning should be done immediately after flowering to remove any dead flowers and promote new growth. The plant should be cut back to ground level before winter to prepare for the dormant season.
Propagation of Lupinus hesperius Heller
Lupinus hesperius Heller, commonly known as the Western lupine, is a hardy perennial plant that belongs to the family Fabaceae. The Western lupine is native to the western United States and is known for its vibrant blue and purple flowers clustered on tall spikes. The plant is easy to propagate and can be done through different methods.
Propagation by Seed
Propagation of the Western lupine by seed is relatively easy. The best time to sow the seed is in the fall, as this will give the plant plenty of time to establish before the heat of the summer sets in. Seeds should be sown directly into well-draining soil. The seeds should be covered with a thin layer of soil and watered well. Germination typically occurs in two to three weeks. Once the seedlings have grown tall enough, they can be transplanted to their final location.
Propagation by Division
Lupinus hesperius Heller can also be propagated by division. This is an excellent method for rejuvenating older plants. Propagation by division is best carried out in the fall after the plant has finished flowering. To divide the plant, carefully dig up the root ball and separate it into sections using a sharp, sterile knife. Each section should have its root system and a few shoots. Replant the new divisions in well-draining soil and water in well.
Propagation by Cuttings
Propagation of the Western lupine by cuttings is possible, but it can be challenging. The best time to take cuttings is in the summer. Using a clean and sharp knife, cut a 3-4 inch section from the plant's stem right below the leaf node. Strip off the leaves from the lower portion of the cutting and insert it into a well-draining soil mix. Water the cuttings in well and keep it in a warm, bright area but away from direct sunlight. Roots should appear within a few weeks, and once the cutting has rooted well, it can be transplanted.
Conclusion
Lupinus hesperius Heller is an attractive plant that is relatively easy to propagate. The Western lupine can be propagated through different methods, including seed, division, and cuttings. Whichever method you choose, ensure you do it during the appropriate season and follow the proper process for best results.
