Darmera peltata, commonly known as the umbrella plant or Indian rhubarb, is a fascinating plant that can be a great addition to your garden. However, it’s important to understand its growth habits and potential invasiveness before deciding to plant it.
While darmera peltata is not classified as an invasive plant, it can be quite aggressive in spreading and filling up space in your garden. It spreads through underground rhizomes, which are thick, fleshy roots that can rapidly produce new plants. This can lead to overcrowding and competition with other plants in your garden.
I have personally experienced this aggressive growth habit of darmera peltata in my own garden. I initially planted a small clump of darmera peltata near a pond, thinking it would make a beautiful addition to the water feature. However, within a couple of years, the plant had spread and expanded its reach far beyond its original planting area. It started to dominate the space, choking out other plants in its path.
To control the spread of darmera peltata and prevent it from becoming invasive, there are a few measures you can take:
1. Planting in containers: One effective way to contain the growth of darmera peltata is by planting it in containers. This will restrict the spread of its rhizomes and prevent it from taking over your garden. Make sure to choose a large enough container to accommodate its growth and provide adequate drainage.
2. Regular division and thinning: Darmera peltata can benefit from regular division every few years. By dividing the plant and removing excess rhizomes, you can control its spread and keep it in check. Thinning out crowded areas will also allow other plants to thrive and prevent competition for resources.
3. Strategic placement: When planting darmera peltata, consider its growth habit and potential size. Choose a location that can accommodate its spreading nature without overshadowing or crowding out other plants. Planting it near water features, such as ponds or streams, where it can spread without causing harm to other plants, can be a good option.
4. Regular maintenance: Keep an eye on darmera peltata and regularly monitor its growth. If you notice it spreading excessively or encroaching on other plants, take action to control its growth. This may involve removing excess rhizomes or transplanting it to a more suitable location.
While darmera peltata is not classified as invasive, it can be aggressive in its growth and spread. By taking proactive measures such as planting in containers, regular division and thinning, strategic placement, and regular maintenance, you can enjoy the beauty of darmera peltata in your garden without allowing it to become invasive.
