How to Grow
Plant Indigofera ‘Rose Carpet’ in the best location during the spring or fall, ensuring it receives full sun for optimal flowering, although it can tolerate some shade. Establish the plant in average, well-drained soil; this species tolerates slightly alkaline conditions, which is beneficial in many landscape settings. Avoid planting in areas prone to overly wet or heavy soil, as drainage is key to long-term health.
Water moderately, allowing the soil to dry slightly between waterings, especially once established where Indigofera ‘Rose Carpet’ displays some drought tolerance. Fertilizing is rarely necessary; rich soils often lead to excessive vegetative growth at the expense of blooms. If pruning is desired, remember this plant blooms on new growth.
For gardeners in USDA Zones 5 and 6A, treat Indigofera ‘Rose Carpet’ as an herbaceous perennial. Cut all stems back close to the ground in late winter or early spring just before new growth signals its return—this hard pruning maintains a tidy form. Even in warmer climates, a similar hard pruning can benefit the shrub’s appearance. Be aware that plants may suffer tip damage or die back completely in harsh winters, but vigorous regrowth from the crown is expected.
Landscape Uses
The spreading nature of Indigofera ‘Rose Carpet’ makes it exceptionally versatile for softening hard edges and covering difficult areas. As a fantastic ground cover, it effectively blankets the soil, reducing weeding needs while providing summer color. It is highly recommended for covering slopes where its root structure can help stabilize soil and its low profile keeps sightlines clear.
In mixed borders, ‘Rose Carpet’ serves as an invaluable front-of-border element, complementing taller specimens without obscuring them. Furthermore, its tough constitution allows it to be used effectively in foundation plantings or within open woodland margins where filtered light is present. The dense foliage and low growth habit of Indigofera ‘Rose Carpet’ are ideal for mass plantings used to unify large areas.
