The leaves are compound with three leaflets, and the fruit is a small, flat pod that contains several seeds. The plant grows in dry, rocky areas and can tolerate drought conditions.
Light Requirements
Lotus scoparius var. veatchii requires full sun exposure to grow properly. It is adapted to open, sunny habitats such as grasslands, meadows, and dry slopes. This plant thrives in areas where it receives at least six hours of direct sunlight per day.
Temperature Requirements
This species is typically found in areas with a warm and temperate climate. The ideal temperature range for Lotus scoparius var. veatchii is between 60-85°F (15-29°C) during the day and 30-60°F (-1-15°C) at night. These plants can tolerate mild frost but are not adapted to extreme temperature fluctuations.
Soil Requirements
Lotus scoparius var. veatchii grows best in well-drained and slightly acidic soils. The preferred pH range for this plant is between 5.5 and 7. Soil with poor drainage or that is too alkaline can lead to root rot and other diseases that can damage the plant. This species can also grow in sandy or rocky soils but requires a good amount of organic matter to support its growth.
Cultivation Methods
Lotus scoparius var. veatchii can be grown through either seeds or cuttings. Seeds should be sown in well-drained soil during the fall season, and the seeds should be barely covered with soil. Cuttings should be taken during the active growing season and planted in a rooting medium until roots develop before being transplanted into a larger pot or the ground.
Watering Needs
The Lotus scoparius var. veatchii requires moderate watering. The soil should be kept moist but not overly wet to avoid rotting the roots. The frequency of watering depends on the temperature and humidity of the growing environment. The plant needs more water during the growing season, but during the dormant season, it requires less frequent watering.
Fertilization
The plant needs a balanced fertilizer, especially during the active growth period. A slow-release fertilizer applied in the early spring can sustain the plant throughout the growing season. Over-fertilization can lead to excessive vegetative growth, which can affect flowering.
Pruning
To encourage bushy growth, Lotus scoparius var. veatchii can be pruned in early spring before new growth begins. Cut back the previous year's growth by one-third or more. Deadhead any spent flowers to encourage continuous blooming throughout the season. If the plant becomes too leggy, prune back to the base of the plant, and this will encourage new growth.
