Invasive ‘ornamental’ should be banished
“It is clear that additional research is necessary to develop effective controls,” Langeland said. “In the meantime, it is important that each of us do our part to minimize the spread of crested floating heart.”
Crested floating heart should not be purchased for any use—landscape ponds or otherwise. Those persons with it already on their property should use all means possible to remove it immediately and dispose of it far away from any body of water—not leaving it on the surface for birds to spread.
Additional background on crested floating heart and its relatives, including identification are listed below:
- Crested floating heart reproduces vegetatively from tubers, daughter plants, rhizomes and small fragments.
- It features small white flowers that bloom from summer to fall.
- Each flower has five petals with ruffled crests that resemble a rooster’s comb.
- Heart-shaped leaves float on the water’s surface, supported by slender tuberous roots that are typically submerged in sediment.
- The plant can grow in shallow drainage ditches and along shorelines, but also has been found to thrive in 10 feet or more of water.
- Yellow floatingheart (Nymphoides peltata) and water snowflake (Nymphoides indica) are also known to be invaders.
- Big floatingheart (Nyphoides aquatica) and little floatingheart (Nyphoides cordata) are native to North America.
