Ajuga reptans ‘Tropical Toucan’ is a popular perennial ground cover known for its vibrant foliage and spreading habit. Gardeners are drawn to this cultivar for its ability to create a colorful, low-maintenance carpet in various garden settings. It offers an easy way to introduce striking color and texture to landscapes.
Unique Features of Tropical Toucan
Its striking foliage distinguishes ‘Tropical Toucan’ from other Ajuga varieties. It boasts large, wavy leaves with brilliant gold or yellow hues, often accompanied by reddish stems. This golden color provides consistent year-round interest. The plant also produces spikes of cobalt-blue flowers that rise above the foliage in late spring to early summer, creating a vivid contrast. This compact cultivar typically reaches a height of 4 to 6 inches and can spread up to 18 to 24 inches wide, forming a dense mat.
Planting and Growing Conditions
For Ajuga ‘Tropical Toucan’, select the right location and provide suitable environmental conditions. This plant thrives in partial to full shade, though it tolerates full sun in cooler climates if consistent moisture is maintained. In warmer regions, providing afternoon shade is recommended to prevent leaf scorch and ensure the best foliage color. ‘Tropical Toucan’ adapts to various soil types, including clay, loam, sand, and silt, but performs best in well-drained, moderately fertile soil. Good drainage prevents crown rot.
Consistent moisture is beneficial, but avoid soggy conditions. Once established, it exhibits some drought tolerance. For optimal growth, the soil pH should be slightly acidic (4.5 to 6.5), though it tolerates a broader range. When planting, space individual plants 6 to 9 inches apart to allow for spreading, ensuring the crown is not buried too deep, which can lead to rot.
Ongoing Care and Maintenance
Ajuga ‘Tropical Toucan’ is low-maintenance once established. Fertilizing is generally not frequent; if the soil is poor, a light application of a slow-release granular fertilizer or organic compost in spring is sufficient. Avoid over-fertilizing, which can lead to crown rot and foliage burn. Water moderately, ensuring the soil dries slightly between waterings to prevent root issues.
Pruning involves removing spent flower spikes after blooming to maintain tidiness, which can be done by shearing or mowing larger plantings on a high setting. While generally pest-free, good air circulation helps prevent crown rot, especially in humid climates. If plantings become too dense, thinning out crowded groupings by dividing runners can rejuvenate the plant and reduce rot. It is also deer and rabbit resistant.
Ideal Garden Applications
Ajuga ‘Tropical Toucan’ is versatile for various garden applications. It excels as a vibrant ground cover, particularly in shaded or partially shaded areas where its golden foliage brightens darker spots. Its dense, spreading habit effectively suppresses weeds, creating a carpet under trees and shrubs or on banks and slopes.
Beyond ground cover, ‘Tropical Toucan’ is an excellent choice for container plantings, where its color and texture can serve as an accent or “spiller” element. It also performs well in rock gardens, along borders, or as an edging plant, providing striking contrast. Combining it with plants like Heuchera, Hosta, Brunnera, or Pulmonaria creates multi-seasonal, visually interesting displays due to its vibrant gold leaves and cobalt-blue flowers.
