How to Prune Wild Perennial Lupine?

Wild Perennial Lupine (Lupinus perennis)
Wild Perennial Lupine, a member of the pea family, showcases striking blue flower spikes and enriches the soil with nitrogen. To stimulate further blossoms, remove faded flower stalks. While removing spent blooms after the first flowering reduces seed output, it encourages a subsequent bloom. Perform light trimming to preserve its form and eliminate any diseased or compromised stems. The ideal time for pruning is in spring once the danger of frost has passed, but prior to the emergence of new growth; light trimming can also be done during summer and autumn. Pruning enhances the plant's vitality and aesthetic appeal, guaranteeing a strong presence in the garden.
