yellow floating heart

Nymphoides peltata

The yellow floating heart (Nymphoides peltata) is an aquatic plant, typically with bright yellow, saucer-shaped flowers. The heart-shaped, floating leaves are green on top and white beneath, producing a pleasant contrast. Growing in water, it develops an extensive root system with creeping rhizomes and many small adventitious roots. It’s native to the western coast of Europe and can thrive in still and slow-moving water. Its flowers bloom from March to September and its roots can spread rapidly, so it’s important to check its growth and spread it out annually. It adds beauty to any wet area, pond, or lake and requires little maintenance.

watering

Watering for the yellow floating heart plant should be heavy, but not excessive - aim for approximately twice a week. During the growing season - spring and summer - the plant should be watered once in the morning and once in the evening, to allow the soil between the 2 waterings to dry fully. During the winter months, the plant should be watered less often - about once every 3-5 days. Make sure to use lukewarm water when watering this plant, as the roots need to be kept warm in order to promote new plant growth.

sunlight

The yellow floating heart plant species is best suited for bright sunlight. The plant should receive at least 4 to 6 hours of direct sunlight each day. For optimal results the plant should receive morning sun and some additional midday light. During the hottest months, it is best to protect your yellow floating heart from the sun by providing partial shade. To ensure that your yellow floating heart receives adequate sun, move the pot to different areas of your outdoor space each day, depending on the sun’s location and the amount of shade.

pruning

Nymphoides peltata, also known as Yellow Floating Heart, should be pruned regularly throughout the growing season. Pruning should begin in early spring, once new growth begins to appear. Cut back any dead or damaged stems and carefully prune the foliage to maintain a bushy appearance. Pinch out the tops of stems to encourage lateral growth for fuller plants. When flowering is complete, reduce the entire plant back to about 3 inches in height, taking care not to prune more than 1-third of the total growth at 1 time. This will promote a more bushy shape. During summer, trim off any flowering stems that appear to reduce the plant’s energy resources and ensure a neat and tidy overall appearance. Pruning should be complete by mid-autumn.
