Timber Milkvetch

Astragalus miser var. miser

Timber Milkvetch (Astragalus miser var. miser) is a perennial wildflower native to western North America, and is commonly found in dry, forested regions. It produces small clusters of pinkish-purple, pea-shaped flowers that can bloom from late spring to early summer. Its foliage is small and narrow with bright green leaves. This plant grows in clumps, and may reach heights of four feet tall. The timber milkvetch is a great choice for gardeners looking to add color and texture to their gardens. It is also an excellent source of nectar for butterflies, bees, and other beneficial insects. Its drought tolerance makes it a great choice for xeriscaping.

watering

Timber Milkvetch should be watered when the soil begins to dry at the top, usually every 2-to-3 weeks. During hot, dry weather, it may need to be watered more frequently. When watering, add water until the soil is thoroughly saturated, and then allow it to dry before watering again. Too much water can lead to root rot, so make sure that the soil has a chance to drain before watering again.

sunlight

Timber Milkvetch (Astragalus miser var. miser) is native to the US Southwest, and thrives in habitat that receives full sun during the winter months. During the spring and summer, Timber Milkvetch typically requires 4 to 6 hours of direct sunlight each day. During the fall, up to 8 hours of direct sunlight is optimal. Areas of partial shade during all 3 periods of the year, however, are also beneficial to the species.

pruning

Timber Milkvetch (Astragalus miser var. miser) requires pruning once a year in late winter or early spring, before buds break dormancy. Pruning should be done with the intention of opening up the center of the plant while leaving a symmetrical shape. This will help with airflow and reduce the risk of disease and pest infestations. Remove any dead, diseased, damaged, or crossing branches. Leave only healthy branches that are evenly distributed around the plant's crown. After pruning is complete, spread nutrient-rich compost around the base of the plant to encourage healthy growth.
