Where to find Virginia Waterleaf
Virginia waterleaf is a perennial typically found in low woods, thickets, ravine bottoms, bluff bases, river flood plains and stream valleys. It is a perennial native to moist and wet woods in northwestern North America, ranging from Quebec to Manitoba in Canada and south to North Carolina and Tennessee.
Recognize it by five (5) long narrow sepals with feathery edges under the flower head. One plant has 1 or 2 clusters on a stem, and may have multiple stems. It will bloom in white or violet colours, from May to June. Seeds occur in July and/or August. Virginia waterleaf presumably gets its name from the water-like spots on its leaves.
Bumble bees, carpenter bees, and other bee species enjoy it as well.
Caring for Virginia Waterleaf
It is best grown in consistently moist, well-drained soils in a light shady spot. They can grow aggressively in optimum conditions.
Propagating Hydrophyllum virginianum
Hydrophyllum virginianum is recommended for covering bare spots and to help stop soil erosion. It is also good for planting where buckthrorn has been removed. It can be planted in the spring or early fall. For best results of seed propagation, sow outdoors immediately after collection. It is not recommended for small gardens as it spreads aggressively.
Flowers are followed by seed capsules. When ripe the capsules split open to release the small seeds. It self-seeds readily and division is the best method to propagate. The best time to divide these plants is in the fall, after it has gone dormant. Ensure there are buds and some roots on each split portion.
