Two Grooved Milk Vetch

Astragalus bisulcatus var. bisulcatus

Two Grooved Milk Vetch is a perennial legume native to much of North America. It is a low-growing, spreading plant growing to heights of up to 6 inches. Its stems have two sharp grooves running along their length. The leaves are compound, with up to 16 small oval leaflets. In the late spring and early summer, it bears clusters of small lilac or pinkish-purple flowers. These flowers attract various pollinators and give way to small, curved seed pods. Growing in meadows, prairies and other dry areas, Two Grooved Milk Vetch provides forage for livestock and is an important food source for several species of butterfly and bee.

watering

Beckwith's Milkvetch requires frequent watering, typically every 3-4 days during the summer season and every 7-10 days during the winter season. Make sure the soil has drained completely between waterings, as Waterlogging can lead to root rot. During dry periods, water deeply and frequently. In spring give them a good deep soaking once a week, and then about twice a week during the peak of the growing season.

sunlight

Beckwith's Milkvetch requires about 4-6 hours of sunlight each day to grow and thrive. It prefers full sun in the morning and afternoon with some shade in the middle of the day. Direct afternoon sun can be too intense in some climates. This plant species grows best in climates such as those of the western United States and will tolerate short periods of drought. It is important to provide adequate drainage when growing this species and to water it regularly to ensure adequate growth.

pruning

Beckwith's Milkvetch should be pruned in late summer (around August). Pruning should be minimal, focusing on removing dead or damaged stems and thinning out any overcrowded growth. It is also necessary to shape the plant by removing branch tips. Pruning should not be too severe, and it should never remove more than 1 third of the plant's foliage, or more than 1 third of its branches. If Beckwith's Milkvetch is grown for its flowers, it may be necessary to thin out some of the blooms to prevent the plant from becoming too crowded.
