giant Solomon's seal

Polygonatum biflorum var. commutatum

Giant Solomon's seal (Polygonatum biflorum var. commutatum) is a hardy, easily grown perennial plant. The leaves are large, and they arch gracefully over the tips of the stems. In late spring into summer, white, bell-shaped flowers dangle from the tips of the stems. The flowers are followed by decorative blue berries that gradually turn dark purple at the end of the summer. Given plenty of sunny space, these plants can reach up to 6 feet in height and make a great, low maintenance statement in a garden or landscape.

watering

Giant Solomon's seal (Polygonatum biflorum var. commutatum) should be watered when the top 1-2 inches of soil becomes slightly dry, until the top layer is damp. The amount of water needed will vary depending on an individual plant's soil type and exposure, but it is important to water thoroughly, so that most of the soil in the pot is damp. Aim for 1-2 inches of water per week, but you may need to adjust this amount based on your plant's individual needs. Additionally, it is important to water at the base of the plant and not from above the foliage to help discourage disease development.

sunlight

Giant Solomon's seal (Polygonatum biflorum var. commutatum) is a shade-loving woodland plant native to North America. The plant grows best in partial shade, with filtered sunlight for most of the day. It prefers bright, indirect light, with some shade from trees or structures during the hottest part of the day. Full sun is too intense and will cause the leaves to sunburn. However, too little light will cause the plants to become lanky and floppy. The ideal amount of sunlight for this plant species is 5 to 6 hours a day.

pruning

Giant Solomon's Seal (Polygonatum biflorum var. commutatum) should be pruned annually in late winter or early spring. Pruning should be minimal and used only to shape the plant, as light pruning will help to maintain an even shape throughout the growing season. Remove any dead, damaged, or crossing branches to prevent them from interfering with healthy growth. Pruning can also promote bushier, fuller plants, but be careful not to cut back too much or the plant will not flower. Wait until the biggest flush of blooms appear and then cut back any types to the desired size.
