Canadian milkvetch (Astragalus canadensis) is found not only in many parts of Canada, but also across the United States as well. It is the largest variety of milkvetch--also written milk vetch or milk-vetch--growing up to 3 feet tall. It has white or light yellow flowers which typically bloom anywhere between May and August. Canadian Milkvetch is extremely easy to care for and normally needs little to no pruning to thrive.
Cut off Canadian milkvetch near the bottom of the plant to enjoy their blooms in vases. Use sharp hand held clippers. This is not a common cut flower, but because it's beautiful, it will add interest to any floral display.
Cut off spent blooms at the bottom of the stem near the base of the plant. This may encourage more blooms.
Prune away damaged or diseased leaves and stems. Also, prune away suckers (small shoots coming out of the ground near the base of the plant) since they use up valuable nutrients.
