Planting & Growing
Umbrella Plant will grow to be about 4 feet tall at maturity, with a spread of 4 feet. Although it's not a true annual, this fast-growing plant can be expected to behave as an annual in our climate if left outdoors over the winter, usually needing replacement the following year. As such, gardeners should take into consideration that it will perform differently than it would in its native habitat.
This plant does best in full sun to partial shade. As an aquatic plant, it requires a suitable water garden environment and will benefit from special planting and ongoing care practices; consult one of our in-store experts for further details and instructions. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This species is not originally from North America. It can be propagated by division.
Umbrella Plant is a fine choice for the water garden, but it is also a good selection for planting in outdoor pots and containers. Because of its height, it is often used as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when grown in outdoor pots and containers, aquatic plants like this one will require a special growing environment that meets their requirement for consistent moisture.
