The Chrysothamnus viscidiflorus var. pumilus can grow in a variety of soils but prefers well-draining sandy or loamy soils. It can tolerate mildly acidic to slightly basic soil pH levels ranging between 6.0-7.5. The plant is also adapted to grow in nutrient-deficient soils and can thrive in dry, rocky terrain.
Cultivation Methods
Chrysothamnus viscidiflorus (Hook.) Nutt. var. pumilus (Nutt.) Jepson is a hardy plant that grows best in well-drained soil and full sunlight. It can tolerate a range of soil types, including sandy, loamy, and rocky soils. The plant is native to the western regions of North America and can withstand extreme temperatures, making it an ideal choice for hot and dry climates.
Watering Needs
Chrysothamnus viscidiflorus (Hook.) Nutt. var. pumilus (Nutt.) Jepson is a drought-resistant plant and does not require frequent watering. Young plants and those grown in pots may require more regular watering until they become established. Water the plants deeply but infrequently, allowing the soil to dry out between watering sessions. Overwatering can lead to root rot and other diseases.
Fertilization
Chrysothamnus viscidiflorus (Hook.) Nutt. var. pumilus (Nutt.) Jepson does not require much fertilization. If you notice that the plant is not growing well, you can apply a slow-release fertilizer in the spring. Avoid using high-nitrogen fertilizers, as this can cause excessive growth and decrease the plant's overall health.
Pruning
Pruning is not necessary for Chrysothamnus viscidiflorus (Hook.) Nutt. var. pumilus (Nutt.) Jepson, but you can prune the plant to keep its shape and size under control if desired. Prune the plant in early spring before new growth appears. Remove any dead, damaged, or diseased branches. Trim back the tips of the branches to encourage bushier growth. Avoid pruning more than one-third of the plant's total size at once.
Propagation of Chrysothamnus viscidiflorus var. pumilus
The Chrysothamnus viscidiflorus var. pumilus plant can be propagated through both vegetative and sexual means.
Vegetative Propagation
One of the primary methods of vegetative propagation for this plant is through stem cuttings. To propagate through stem cuttings, select a healthy stem, approximately 4-6 inches long, that has several leaves and no flowers or buds. Cut the stem at a 45-degree angle with a sharp, sterilized knife. Next, remove the lower leaves, leaving only a few at the top. Dip the cut end of the stem in rooting hormone, which can be purchased at most garden centers. Place the stem cutting in a well-draining potting mix, water it well, and cover with a clear plastic bag to create a greenhouse effect. Keep the soil moist and the cutting out of direct sunlight. After a few weeks, roots should start to form, and once they are established, the plastic cover can be removed.
Sexual Propagation
Chrysothamnus viscidiflorus var. pumilus can also be propagated through seeds. Collect seeds in the fall when the plant produces mature seeds. Remove the seeds from the seed head and store them in a cool, dry place until spring. In the spring, scatter the seeds over well-draining soil that has been prepared by raking and has had any weeds removed. Lightly press the seeds into the soil, water well, and keep the soil moist until the seeds germinate. Germination may take up to a few months, so be patient.
