broom 'Albus'


The Cytisus × praecox 'Albus', also commonly known as white broom or warminster broom, features a dense and bushy appearance. This deciduous shrub blooms prolifically in the spring, with an abundance of small, white, pea-like flowers that cluster together, creating a magnificent display against the green foliage. The leaves are small and trifoliate, meaning they come in groups of three. They are a bright green color, offering a striking contrast to the white blossoms. As the flowering season progresses, these leaves serve as a lush background for the less densely packed, yet still remarkable, white flowers that may continue to appear sporadically. The branches of the white broom are slender and have a slightly arching habit, contributing to the plant's overall rounded and fluffy shape. The texture of the branches is somewhat rough, with a bark that may become increasingly textured as the plant matures. Flower buds typically appear at the tips of the stem and may be slightly fuzzy before they fully open into the characteristic small, papilionaceous (butterfly-like) blossoms. After the blooming period, the flowers may be followed by small seed pods, which eventually dry and may crack open to release seeds. Overall, the white broom's appearance is characterized by its bright, showy flowers, its delicate green leaves, and its somewhat graceful, arching branches.

  • water dropWater

    The White Broom should be watered regularly during its growing season in spring and summer, ensuring the soil is moist but not waterlogged. Typically, watering once a week with 1 to 1.5 gallons of water should suffice, but this can vary depending on climate conditions and soil drainage. During winter, reduce watering to every two to three weeks, providing just enough water to prevent the soil from drying out completely. It's crucial to avoid overwatering as this can lead to root rot.

  • sunLight

    The White Broom thrives best in full sun, so position it in a spot where it receives at least six hours of direct sunlight daily. Avoid places that are shaded for most of the day, as insufficient light can affect its blooming and overall growth.

  • thermometerTemperature

    The White Broom is hardy and can tolerate a range of temperatures, but it performs best when the temperature is between 50 and 75 degrees Fahrenheit. It can survive minimum winter temperatures down to about 20 degrees Fahrenheit, but exposure to severe frost should be avoided. Ideal growing conditions involve moderate temperatures without extreme heat or cold.

  • scissorsPruning

    The White Broom should be pruned immediately after flowering to maintain its shape and encourage bushier growth. Pruning is typically done in late spring or early summer. Cut back flowering stems by about half, taking care not to cut into old wood, as this may not regrow. Annual pruning helps rejuvenate the plant and prompts more profuse blooming in the following season.

  • bambooSoil

    The Warminster Broom (Cytisus × praecox 'Albus') thrives in well-draining soil with a slightly acidic to neutral pH of 6.0 to 7.5. A mix of garden soil, peat, and coarse sand is ideal, which ensures proper drainage while retaining enough moisture.

  • plantRepotting

    Warminster Broom requires minimal repotting, usually only when it outgrows its container. This may not be frequent, as it is typically grown outdoors and has a relatively slow growth rate.

  • water dropsHumidity & Misting

    Warminster Broom is quite tolerant of different humidity levels but prefers moderate humidity. Excessively high humidity can lead to fungal issues, whereas too low might cause desiccation.

  • circleLife cycle

    The Cytisus × praecox 'Albus', commonly known as white broom, begins its life cycle with germination, where its seeds sprout in well-drained soil with full to partial sunlight exposure. Upon sprouting, the seedling stage is marked by the emergence of the first set of true leaves after the initial seed leaves. The vegetative stage follows, with the plant rapidly growing stems and foliage, establishing a robust root system. As it matures, the white broom enters the flowering stage, typically in the spring, showcasing white, pea-like flowers that attract pollinators. After pollination, the flower gives way to seed pods, which mature, dry out, and release seeds for dispersal, completing the reproductive cycle. Finally, after several years, the plant may reach the end of its lifespan, which can be prolonged through proper pruning and care to maintain its vitality and blooming capacity.

      Spring to Early Summer

    • The most popular method of propagation for the Warminster Broom, scientifically known as Cytisus × praecox 'Albus', is through semi-hardwood cuttings. This process typically takes place in late summer. Cuttings about 6 inches (approximately 15 centimeters) long are taken from the current year’s growth. The lower leaves are removed, and the cut end of the cutting can be dipped in rooting hormone to enhance root development. These cuttings are then placed in a well-draining rooting medium such as a mix of peat and perlite. The environment should be kept humid, often by covering the cuttings with a plastic bag or placing them in a propagator, and they are kept out of direct sunlight until roots have developed, which usually takes a few weeks.
