Caltha palustris

Marsh Marigold is a mounded, succulent perennial with large, showy, bright yellow flowers, which bloom April-June. The common name is misleading, since the flowers resemble buttercups rather than marigolds. The glossy leaves are described as having a heart or kidney shape. When ripe, the seed pods split open to disperse the seeds. As the common name suggests, this plant prefers wet, boggy soils. Use it in rain gardens, bog gardens, or shallow water margins of ponds and water gardens.

Callirhoe involucrata

Purple Poppy Mallow is a lovely, drought-tolerant perennial with a long bloom period. The attractive, deeply lobed foliage forms a dense mat, which chokes out weeds. Its cup-shaped, magenta flowers start blooming in the spring and continue through the summer and well into the fall. This perennial is a nectar source for bees and a host plant for butterfly and moth larvae (caterpillars), including Gray Hairstreak (Strymon melinus). It grows well in hot, sunny, dry locations. Purple Poppy Mallow is a versatile plant, which fits into both formal and wildflower gardens. Use it in sunny borders and beds, rock gardens, meadows, hanging baskets, or as a cascading plant over walls. Excellent groundcover for covering slopes and steep banks.

Betula populifolia

Gray Birch is a medium-sized, short-lived deciduous tree with chalky white bark. It grows best in areas where the soil is shaded, cool, and moist. Keep the shallow root system moist by using mulch and watering during dry weather. This tree can be short-lived in New Jersey. It does not tolerate heat and humidity well, and grows best in areas with cool summers. Use Gray Birch in rain gardens and other areas of the yard with moist soil conditions, or in woodland gardens.

Betula papyrifera

Paper Birch is a short-lived deciduous tree with beautiful, white bark that that peels in papery strips. Catkins (elongated, drooping clusters of tiny flowers without petals) appear just before the leaves emerge. The flowers are followed by cone-like fruits holding small, winged seeds. The seeds are a food source for a variety of birds. The dark green leaves turn yellow in the fall. Paper Birch grows best in areas where the soil is shaded, cool, and moist. Keep the root system moist by using mulch and watering during dry weather. This tree can be short-lived in New Jersey. It does not tolerate heat and humidity well, and grows best in areas with cool summers. Under the proper growing conditions, Paper Birch is an excellent specimen tree. It can also be used in woodland gardens.

Betula nigra

River Birch is a large deciduous tree with pinkish-brown, peeling bark, which provides year-round ornamental interest. The dark green, diamond-shaped leaves turn yellow in the fall. It prefers moist to wet soils, and tolerates periodic flooding. An adaptable tree, it will also grow in drier soils. Give this large tree with an extensive root system room to grow!

Betula lenta

Sweet Birch is a large deciduous tree with reddish-brown to reddish-black bark. The cherry-like bark is smooth on young trees and scaly on mature ones. The catkins (elongated, drooping clusters of tiny flowers without petals) appear just before the leaves emerge. The leaves turn golden-yellow in the fall. The seeds are a food source for a variety of birds. Sweet Birch is a host tree for butterfly and moth larvae (caterpillar), including Green Comma (Polygonia faunus).
