Manitoba Maple
Water Arum

Manitoba Maple is a fast growing tree with great fall color. These trees are typically grown as feature or shade trees on larger properties and acreages. Manitoba maples are cold hardy and tolerant of a wide range of soil moisture conditions.

Note that Manitoba Maple is considered toxic to horses.

Water Arum is a native perennial wetland plant known for its showy white oval sheaths (spathe) that surround a yellow-green, cylindrical flower spike (spadix). It has large, oblong, heart-shaped leaves on stems that rise above the water from shallow, spreading rhizomes. The blossoms are followed in late summer by tiny, pear-shaped fruits that ripen to bright red, adding ornamental interest to wet habitats.

Water Arum provides food for birds and small mammals that eat its berries, and its flowers attract pollinators. It can tolerate cold climates and forms colonies in shallow water and saturated soils. It is well-suited for ecological restoration, riparian planting, naturalisation, and habitat projects in wet and shaded environments.
