This plant can grow in a variety of soil types, including sandy, loamy, and clayey soils. It is essential to avoid overwatering as Oxytropis nana Nutt. var. fallax is susceptible to root rot.
Cultivation
Oxytropis nana Nutt. var. fallax (Barneby) Isely is a hardy perennial plant that can thrive in various soil types and conditions. It is adaptable to both sunny and partially shaded areas and prefers well-drained soil.
The plant is best propagated from seeds, which can be sown in the autumn or early spring. Choose a location with good drainage and add compost to the soil before planting the seeds. Cover the seeds with a thin layer of soil and water them regularly until they germinate.
Watering Needs
The soil should be kept moist, but not waterlogged, at all times. Water the plant deeply at least twice a week during dry weather, and adjust watering frequency based on weather conditions and soil moisture levels.
Avoid splashing water on the leaves, as this can lead to the development of fungal diseases.
Fertilization
Oxytropis nana Nutt. var. fallax (Barneby) Isely does not require frequent fertilization. However,you can apply a balanced, slow-release fertilizer at the beginning of the growing season to promote healthy growth. Follow the manufacturer's instructions and avoid over-fertilizing.
Pruning

Do not remove more than one-third of the plant's overall size when pruning.
Propagation of Oxytropis nana Nutt. var. fallax (Barneby) Isely
Oxytropis nana Nutt. var. fallax (Barneby) Isely, commonly known as the dwarf oxytrope or fallax or dwarf locoweed, is a species of leguminous plant that grows in dry, rocky areas, and alpine tundra. The plant's hardiness zone ranges from 5 to 8, and it is commonly propagated from seeds or cuttings.
Propagation from Seeds
Propagation from seeds is the most common method of propagating Oxytropis nana var. fallax. Collect ripe seed pods in late summer or early fall when the pods start to turn brown and develop a papery texture. Once the seed pods are collected, air dry them at room temperature for a week or two. After the pods are completely dry, gently shake them and separate the seeds from the pod. You can also crush the pods with your hands to extract the seeds.
After the seeds are collected, fill a seed starting tray with seed-starting mix and plant the seeds about 1/8 inch deep. Keep the soil moist and warm (around 70°F) until the seeds germinate, which can take up to two weeks. Once the seedlings reach about two inches high, transplant them into individual pots. Continue to grow the seedlings until they are large enough to be transplanted into the garden.
Propagation from Cuttings
Propagation of Oxytropis nana var. fallax from cuttings is also a viable option. Cuttings are best taken during early summer when the plant is in its growing phase. Cut 3-4 inch long, healthy stem cuttings from the tips of the plant, making sure that each cutting has at least two nodes where leaves will sprout.
Dip the cuttings in rooting hormone powder and plant them in a moist, well-draining potting mix. Cover the pot with a plastic bag or use a propagation tray with a clear lid to maintain humidity. The cuttings will form roots in about 4-6 weeks. Once rooted, transplant the cuttings into individual pots and grow them until they are large enough to be transplanted into the garden.
