Summary
Source: WikipediaCardamine lyrata, known commonly as Japanese cress and Chinese ivy, is a species of aquatic plant in the mustard family. It is native to the marshes of eastern China and Siberia, as well as Korea and Japan. It flowers from May to June in the wild, with seeds ripening through September. The flowers are bisexual and are pollinated by insects, but are also self-fertile. The species is cultivated as an aquarium ornamental. It needs a supply of cool, slow-moving water and strong light. It can grow rapidly under the right conditions and makes an attractive, bushy plant. It can be grown in ponds as long as the water temperature does not exceed about 82 °F (28 °C). It propagates easily by cuttings and high levels of carbon dioxide speed growth. Some fish will nibble on the leaves.

Once large enough to handle, prick seedlings into individual pots and grow on in light shade in a greenhouse or cold frame for the first two years, planting out when dormant in late summer. Divide in early spring or after the plant dies back in summer. Large clumps can go straight into permanent positions, while smaller clumps are better potted and grown on in a cold frame before planting out in spring.
