‘Magic Carpet’ Japanese Spirea (Spiraea japonica ‘Magic Carpet’). Spiraea japonica ‘Magic Carpet’ is a compact summer spirea known for its evolving colorful foliage and sustained pink blooms. This deciduous shrub develops a low, dense habit, significantly wider than it is tall, forming a structured cushion ideal for borders, mass plantings, and foundation plantings. Its new foliage emerges orange-red in spring, turns bright golden yellow in summer, then takes on coppery hues in fall, ensuring continuous decorative interest. In summer, corymbs of vibrant pink flowers elegantly contrast with the golden foliage and attract pollinators.

To plant ‘Magic Carpet’ Japanese spirea, choose a suitable exposure: full sun to partial shade. The recommended soil is well-drained, tolerating various soil types. Water the root ball before planting and ensure water can drain after planting. During establishment, check the soil moisture by hand before watering again. Spread mulch around the base, leaving the crown clear. Avoid systematic fertilizer applications without considering soil richness. In Quebec, choose a period when the soil is thawed and easy to work with.

Allow a width of 1 m (3.3 ft) to plan this plant's space in the garden. The indicated height of 60 cm (2 ft) helps choose its position relative to neighboring plants. Maintain access to the base for weeding, checking moisture, and removing damaged parts. Combine this variety with plants whose light and water needs are compatible. If you are considering a container, first check that its volume and drainage are suitable for root development. Roots in pots are more exposed to cold than those planted in the ground.
