Warminster Broom Cytisus × praecox 'Warminster'
ABOUT
Cytisus × praecox 'Warminster', commonly known as the Warminster broom, is a deciduous, arching shrub known for its slender branches that create a somewhat weeping form. This plant boasts a profusion of small, trifoliate leaves that are typically a light to mid-green color, giving it a fine texture that can appear feathery or airy from a distance. In the blooming season, it becomes exceptionally ornamental due to the abundance of small, pea-like flowers. The flowers are commonly a soft, creamy yellow shade and cover the branches densely, often from the base of the plant all the way to the tips, creating a sweeping, cascading effect of color. The profuse bloom gives the entire shrub a vibrant, cheerful look that can light up a garden. When not in bloom, the Warminster broom's foliage provides a delicate, green backdrop for other plants in the landscape. The branches, while sturdy, have a fine, almost wiry appearance that complements its overall elegance.

WaterWarminster Broom prefers well-drained soil and does not like to be overly watered. It's best to water the plant deeply but infrequently, allowing the soil to dry out somewhat between waterings. During the active growth season in spring and summer, watering every 7-10 days with about 1 to 1.5 gallons per plant should be sufficient. However, always adjust watering based on rainfall and temperature, reducing the frequency during cooler and wetter months. Overwatering can lead to root rot, so ensure good drainage.
LightThe Warminster Broom thrives best in full sun conditions. It should be positioned in a spot where it can receive at least six hours of direct sunlight daily. The more sunlight the plant receives, the better it will grow and flower. Dappled sunlight can be tolerated but may reduce blooming. Avoid heavy shade as this will significantly impact the plant's health and flowering potential.
TemperatureWarminster Broom is hardy and can tolerate a range of temperatures; however, it flourishes in conditions between 65°F to 75°F. It can survive minimum temperatures down to around 10°F and maximum temperatures as high as 80°F to 90°F. Providing good air circulation around the plant can help it deal with temperature fluctuations.
PruningPruning Warminster Broom is essential for maintaining its shape and encouraging new growth. Prune immediately after flowering, typically in late spring or early summer, by trimming back the flowered stems to strong young growth. This will allow time for the new growth to flourish and set buds for the following year. Avoid heavy pruning into old wood as it may not resprout.
CleaningNot needed
SoilWarminster Broom thrives in well-drained sandy or loamy soil with a pH range of 6.0 to 7.5. An ideal soil mix would contain two parts loam, one part sand, and one part peat for acidity adjustment. Ensure good drainage to prevent root rot.
RepottingWarminster Broom is typically grown outdoors and does not require frequent repotting. If grown in a container, repot every two to three years to refresh the soil and prevent it from becoming root-bound.
Humidity & MistingWarminster Broom prefers moderate humidity levels but is quite adaptable and can tolerate the varying humidity conditions typical of outdoor environments. Avoid overly humid conditions to prevent disease.

Life cycleCytisus × praecox 'Warminster', commonly known as the 'Warminster Broom', begins its life cycle as a seed, typically germinating in the spring when temperatures are conducive to growth. The seedling stage follows, where the plant begins to develop its root system and its first true leaves. As it enters the vegetative stage, the Warminster Broom rapidly grows and branches out, forming a sturdy structure with its characteristic green stems. Flowering typically occurs in late spring to early summer, showcasing its vibrant yellow flowers that attract pollinators. Following pollination, the plant produces small pods containing seeds, which mature by late summer. These seeds are either dispersed naturally or collected for propagation, completing its life cycle and potentially giving rise to new plants for the next growing season.
PropogationPropogation time
Spring to Summer
The most popular method of propagation for the Cytisus × praecox 'Warminster', commonly known as Warminster Broom, is through semi-hardwood cuttings. This technique is usually performed in late summer. Cuttings about 4 to 6 inches (approximately 10 to 15 centimeters) long are taken from the current year's growth. The leaves on the lower half of the cutting are removed, and the cut end is dipped in rooting hormone to encourage root development. The prepared cutting is then inserted into a pot filled with a mixture of perlite and peat moss. The pot should be kept in a warm, well-lit area but out of direct sunlight, and the growing medium should be kept consistently moist but not waterlogged. Roots usually develop within a few weeks to a couple of months, after which the new plants can be gradually acclimatized to outdoor conditions and eventually planted out.
