Washington Hawthorn

Thiessen Saskatoon is a deciduous shrub that produces delicious edible fruit. It is one of the most productive saskatoon varieties. Its fruit is great in pies, preserves or eating fresh.

Thiessen Saskatoon is popular with U-Picks and home owners because of its taller tree-like shape and larger berries. But it is not the best choice for berry orchards as it is too tall for most mechanical harvesting equipment.

Washington Hawthorn is an attractive ornamental shrub that is dense enough to plant as a privacy screen. It produces clusters of white blooms in late spring to early summer.

Washington Hawthorn's red berries last throughout winter, bringing squirrels and birds to your property. In the fall, its foliage turns beautiful orange, scarlet, or purple.

One of the most overlooked trees on the prairies. This tree is often used as rootstock, a wildlife attractor, or a boulevard hedge. Give this one a second look.

This species is also known as one of the more salt-tolerant species for those with saline soils.

Please note: this plant is poisonous to dogs.
