Origin
Sedum douglasii Hook. ssp. ciliosum (T.J. Howell) Clausen, more commonly known as Douglas' stonecrop, originates from North America. Specifically, it is found in the coastal regions of western North America from Alaska to California.
Common Names
Douglas' stonecrop is also commonly referred to as dwarf stonecrop, Sierra stonecrop, and cliff stonecrop.
Uses
As a plant, Douglas' stonecrop is typically used as an ornamental garden plant due to its low-growing, ground-covering nature and its yellow, star-shaped flowers. It is well-suited to rock gardens or other well-draining soil environments, and can also be grown in rock crevices or on rocky slopes. Additionally, Native American tribes have used the plant for medicinal purposes, including as a treatment for coughs and colds.
General Appearance
Douglas' stonecrop is a low-growing perennial succulent plant that typically grows to be between 5-15 cm tall and 15-45 cm wide. It typically has small rosettes of leaves that are roughly spatula-shaped and have a waxy appearance. The leaves themselves are typically around 1-2 cm long and are arranged in a basal rosette. The yellow flowers bloom in the summer months and are roughly star-shaped, measuring around 0.5 cm in diameter. The plant spreads easily via offsets or cuttings and prefers a well-draining soil environment.
Growth Conditions for Sedum douglasii Hook. ssp. ciliosum (T.J. Howell) Clausen
Sedum douglasii Hook. ssp. ciliosum (T.J. Howell) Clausen, commonly known as the Douglas' stonecrop, is a succulent plant found in western North America. It is a hardy plant that can thrive in a range of growth conditions. Here are the typical growth conditions required for Sedum douglasii Hook. ssp. ciliosum:
Light
Sedum douglasii Hook. ssp. ciliosum prefers to grow in full sun, but it can tolerate light shade. It is important to provide this plant with adequate sunlight for it to bloom and maintain its vibrant colors. If the plant is not getting enough sunlight, it may become leggy, and its colors may be off.

However, it prefers temperate weather conditions and will grow better in areas where temperatures range from 45°F to 75°F.
Soil Requirements
Sedum douglasii Hook. ssp. ciliosum prefers well-draining soil with a slightly acidic to neutral pH level. It can tolerate a range of soil types, including sandy and rocky soil. This plant grows best in soil that is rich in organic matter and has good drainage. A layer of mulch around the base of the plant can help to maintain soil moisture levels.
Overall, Sedum douglasii Hook. ssp. ciliosum is a hardy plant that can thrive in a range of growth conditions. It prefers full sun, moderate temperatures, and well-draining soil with a slightly acidic to neutral pH level. Providing the plant with these growth conditions will help it to bloom and maintain its vibrant colors throughout the growing season.
Cultivation
Sedum douglasii Hook. ssp. ciliosum (T.J. Howell) Clausen is a drought-tolerant plant that prefers well-drained, slightly acidic to alkaline soil. It grows well in full sun to partial shade. It can be propagated from seeds or stem cuttings in the spring.
Watering needs
Sedum douglasii Hook. ssp. ciliosum (T.J. Howell) Clausen requires moderate watering during the summer months. However, it is important not to overwater the plant, as excess moisture can lead to root rot. During the winter months, reduce watering as the plant can tolerate dry soil conditions.
Fertilization
Sedum douglasii Hook. ssp. ciliosum (T.J. Howell) Clausen does not require frequent fertilization. However, a slow-release fertilizer can be added to the soil in the spring to provide necessary nutrients for the growing season.
Pruning
Sedum douglasii Hook. ssp. ciliosum (T.J. Howell) Clausen can be pruned in the spring to control its size and shape. The plant can be cut down to the ground after flowering to encourage new growth. Dead or damaged stems can be removed at any time of the year.
Propagation of Sedum douglasii Hook. ssp. ciliosum (T.J. Howell) Clausen
Sedum douglasii Hook. ssp. ciliosum (T.J. Howell) Clausen, commonly known as Douglas' stonecrop, is a succulent native to North America. It is a hardy plant that grows well in rock gardens, in pots, and in dry, sunny spots. Propagation of this plant is easy and can be done through stem cuttings, leaf cuttings, and division.
Propagation by Stem Cuttings
The easiest way to propagate Sedum douglasii Hook. ssp. ciliosum is through stem cuttings. To do this, select a healthy stem and cut it at a 45-degree angle. Make sure the cutting is at least 5 cm long and has a few leaves. Remove the lower leaves from the stem, leaving only a few at the top. Allow the cutting to dry for a day or two before planting it in well-draining soil. Water the cutting sparingly until it develops roots, which should take a few weeks.
Propagation by Leaf Cuttings
Propagation by leaf cuttings is also possible with Sedum douglasii Hook. ssp. ciliosum. Select a healthy leaf and cut it from the stem with a sharp knife. Make sure the leaf is at least 3 cm long and has a stem attached to it. Plant the leaf in a well-draining soil mix, making sure the stem is covered but the leaf is exposed. Water the soil sparingly until the plant develops roots and starts to grow.
Propagation by Division
Sedum douglasii Hook. ssp. ciliosum can also be propagated through division. This method is best done in the spring or early summer when the plant is actively growing. Gently dig up the plant and separate it into smaller clumps. Each clump should have a few roots and stems attached to it. Replant the clumps in well-draining soil, water sparingly, and give them plenty of sunshine.
Propagation of Sedum douglasii Hook. ssp. ciliosum is easy and can be done with minimal effort. With the three methods listed above, you should be able to propagate the plant successfully. Keep in mind that it is important to use well-draining soil, water sparingly, and give the plant plenty of sunshine to encourage healthy growth.
Pest and Disease Management for Sedum douglasii Hook. ssp. ciliosum (T.J. Howell) Clausen
Sedum douglasii Hook. ssp. ciliosum (T.J. Howell) Clausen, commonly known as the Douglas stonecrop, is a hardy perennial plant native to North America. Like all plants, it is susceptible to certain diseases and pests, which can impact its health and appearance. Here are some common issues that can affect Sedum douglasii Hook. ssp. ciliosum and how to manage them.
Diseases
Sedum douglasii Hook. ssp. ciliosum is not particularly prone to disease, but it can suffer from fungal infections if conditions are favorable. The most common fungal disease that affects Sedum douglasii Hook. ssp. ciliosum is powdery mildew. This appears as a white, powdery substance on the leaves, and can cause stunted growth and leaf drop.
To manage powdery mildew, start by promoting good air circulation around the plant. This can be achieved by pruning back nearby vegetation and not overcrowding the plant. Additionally, avoid overhead watering as much as possible, as this can create humid conditions that encourage fungal growth. If powdery mildew is present, remove any infected leaves and dispose of them carefully. You may also consider using a fungicidal spray to protect the plant against further infection.
Pests
Sedum douglasii Hook. ssp. ciliosum is generally not attractive to pests, but it can be nibbled on by slugs and snails. These pests are particularly common in moist, shady environments and can cause extensive damage if left unchecked.
To manage slugs and snails, start by removing any debris or plant litter from around the plant, as this can provide hiding places and breeding sites. Additionally, consider using copper tape or barriers around the base of the plant, as this can prevent these pests from reaching the leaves. You may also want to try using a natural slug or snail repellent, such as diatomaceous earth or coffee grounds.
By being vigilant and taking steps to prevent diseases and pests, you can help keep your Sedum douglasii Hook. ssp. ciliosum happy and healthy.
