Yes, anemone bulbs—or more accurately, tubers or corms depending on the species—do multiply over time. As they grow and mature, anemones naturally produce offsets or small new bulbs that form alongside the original. These offsets can eventually be separated and replanted, leading to a gradual increase in the number of flowering plants in your garden. Multiplication usually happens slowly over several growing seasons, but with the right care, such as well-drained soil, proper spacing, and regular watering (especially during the active growing season), the process can be accelerated. Gardeners who want to encourage more blooms often dig up and divide anemone tubers every few years. This not only promotes healthy growth but also prevents overcrowding. Overall, anemones are relatively low-maintenance and, once established, they tend to expand and fill in garden beds, creating a beautiful, naturalized effect.
