Water Arum
Schuettes Oak

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.

Schuettes Oak is a naturally occurring hybrid of Swamp White Oak and Bur Oak. With a faster growth than both parent species, it is one of the fastest growing Oak trees. They are known for growing very large and wide, so space them appropriately. It is considered one of the most adaptable Oaks with little preference on soil conditions. It can handle growing in wet, saturated soils as well as those that are dry, clay, or alkaline.

The Schuettes Oak has very large acorns. They have a large cup portion like the Bur Oak, but without the fringe. Due to the Swamp White Oak parentage, the acorns have less tannins and a sweeter taste. They are a food source for various wildlife including birds, squirrels, and deer.
