Cushion Bush Leucophyta brownii
ABOUT
Commonly known as the cushion bush, Leucophyta brownii appears as a compact, mound-forming plant notable for its striking silver to grey foliage. Its leaves are small, finely textured, and covered with fine, silvery white hairs that give the plant a soft, woolly appearance, resembling a silvery cushion or a soft tumbleweed. The cushion bush produces small, rounded heads of yellowish flowers that blend into the foliage, often nearly hidden by the dense, velvety leaves. These flowers are not particularly showy and are sometimes considered insignificant in comparison to the attractive foliage. Overall, the cushion bush is characterized by its unique color and texture, making it a popular choice for garden contrast when planted among other greenery.

WaterThe cushion bush should be watered sparingly, as it is a drought-tolerant plant native to arid regions. Ensure the soil is well-drained and allow it to dry out between waterings. Typically, watering once every two weeks with about 8-16 ounces of water should suffice. During the winter months or cooler weather, you can reduce watering to once a month as the plant's growth slows down and it requires less moisture. Overwatering can lead to root rot, so it's important not to let the plant sit in waterlogged soil.
LightThe cushion bush thrives best in full sunlight, making it an ideal plant for spots that receive direct light for most of the day. Ensure it has exposure to at least six to eight hours of direct sun, which will promote its dense, silvery foliage and overall health. If grown indoors, a south-facing window would be the best spot for this light-loving plant.
TemperatureThe cushion bush prefers a warm climate and does best in temperatures ranging from 40 to 90 degrees Fahrenheit. It can endure brief periods of cooler temperatures but should not be exposed to conditions below freezing (32 degrees Fahrenheit). Ideal growing conditions are found within the 60-75 degrees Fahrenheit range, which will encourage healthy growth without putting undue stress on the plant.
PruningPruning the cushion bush is important for maintaining its shape and encouraging new growth. Prune in the late winter or early spring, before new growth begins. Cut back any dead or damaged stems, and shape the plant as desired. Pruning once a year is generally sufficient to keep your cushion bush healthy and looking its best. Do not prune too heavily, as this can stress the plant and reduce its vigor.
CleaningAs needed
SoilCushion bush prefers well-draining sandy or gravelly soil with moderate fertility. A mix of equal parts sand, potting soil, and peat is ideal. The soil pH should be slightly acidic to neutral, ranging from 6.0 to 7.5.
RepottingCushion bush has a slow growth rate and requires repotting infrequently, about once every 2 to 3 years or when the plant has outgrown its container.
Humidity & MistingCushion bush thrives in dry conditions and does not require high humidity. It prefers typical indoor humidity levels between 40% to 50%.
Suitable locationsIndoor
Place cushion bush in a bright spot with sandy soil and minimal watering.
Outdoor
Choose a sunny location with well-draining soil and low water needs.

Life cycleLeucophyta brownii, commonly known as Cushion Bush, starts its life as a seed which germinates in favorable conditions, typically in well-drained soil and full sunlight. Upon germination, it develops a root system and sprouts its first silvery-grey leaves. As the plant grows, it forms a dense, mounded cushion-like shape with branching stems covered in small, rounded leaves. Cushion Bush reaches maturity and begins to flower, showcasing yellowish flower heads, mainly in summer or fall, which are less noticeable against the foliage. After pollination, typically by wind or insects, the flowers produce seeds that are then dispersed by wind or wildlife. The plant is a perennial and will continue this cycle, with some individuals living several years under optimal conditions.
PropogationPropogation time
Spring to Summer
Propogation: Cushion Bush (Leucophyta brownii) is commonly propagated using semi-hardwood cuttings. The ideal time for taking cuttings is during the late summer or early fall when the plant's growth begins to slow, and the stems are no longer green but not yet fully mature and hardened. To propagate, select a healthy stem and cut a piece around 4 to 6 inches (about 10 to 15 centimeters) long, ensuring there are several sets of leaves. Remove the lower leaves to expose a clean section of stem that can be inserted into a rooting medium. Dip the cut end into a rooting hormone powder to encourage root development, then place the cutting into a well-draining potting mix. The cutting should be kept in a warm, humid environment out of direct sunlight until roots have developed, which can take several weeks. Once rooted, the young plants can be gradually acclimatized to outdoor conditions and planted out into their final positions.
