Basket-of-gold (Aurinia saxatilis)
Basket-of-gold (Aurinia saxatilis) offers profuse spring blooms; a low-growing, spreading yellow perennial perfect for rock gardens.
Complete Plant Information
Overview
Aurinia saxatilis, commonly known as Basket-of-gold, is a prized addition to sunny landscapes, famed for its dense, vibrant spring display of golden flowers. This low-growing, spreading perennial creates a stunning visual effect when cascading over stone walls or tucked into rock crevices, living up to its common name. While the initial bloom is spectacular, the plant functions as an attractive, mat-forming ground cover for the rest of the growing season, provided it survives the summer humidity.
Native to central and southeastern Europe, this member of the Brassicaceae family thrives in sharp drainage, mirroring its preferred rocky habitat. Gardeners value Aurinia saxatilis for its ability to tolerate dry conditions and poor soils where many other plants struggle. Proper placement is crucial, as moisture retention, especially in hot climates, can quickly lead to plant decline.
The foliage of this mat-forming perennial is a distinctive gray-green, contrasting beautifully with the intense yellow flowers that appear reliably from April into May. Gardeners looking for dependable early-season color that requires minimal pampering once established should strongly consider incorporating Aurinia saxatilis into dry, sunny borders or scree gardens.

How to Grow
Planting Aurinia saxatilis is best achieved in early spring when new nursery stock becomes available, though seeds can be sown outdoors in early fall or started indoors 8-10 weeks before the last frost. The paramount requirement is soil quality; plant in dry, average to sandy, well-drained soils, strictly avoiding heavy clay which exacerbates moisture issues. While it requires full sun for the best flowering, dappled afternoon shade in extremely hot climates can sometimes benefit the foliage and prolong the plant’s lifespan.
Watering should be infrequent once established, reflecting its drought tolerance. Fertilization is generally unnecessary, as rich soil can lead to floppy, weak growth rather than the desired compact form. The most important cultural step involves pruning. Cut back plants by up to half immediately after the main bloom period finishes to encourage denser, more attractive summer foliage and prevent legginess.
Gardeners must be mindful of regional climate challenges. In hot, humid areas like the St. Louis region, Aurinia saxatilis often proves short-lived, sometimes requiring gardeners to treat it as a temporary annual planted each fall for spring enjoyment. In these challenging areas, ensuring the plant never sits in wet conditions, even briefly, is critical for survival.
Landscape Uses
Basket-of-gold shines in applications where its spreading habit and love of dry conditions can be fully utilized. It is an exceptional choice for rock gardens, nestled between stones or utilized to spill dramatically over the edges of low stone walls, showcasing its naturalized growth pattern. The bright spring flowers make it an excellent choice for border fronts, providing a vibrant band of color against later-blooming perennials or shrubs.
Because of its low stature, it functions effectively as a ground cover in areas too dry or sunny for traditional turf or spreading perennials. Consider using Aurinia saxatilis on sunny, shallow hillsides or slopes where amending the soil for moisture retention is impractical. When planting, pair it with other sun-loving, dry-tolerant companions such as creeping thyme, sedums, or dwarf penstemons that share similar cultural requirements.

Noteworthy Characteristics
Aurinia saxatilis commonly called basket-of-gold is a low-growing, spreading perennial that produces a profuse spring bloom of bright yellow flowers that are particularly attractive in rock gardens, sprawled over rocks or cascaded over rock walls. This is a mat-forming perennial with woody roots that grows to 6-12” tall and features spatulate basal leaves that are gray-green. The genus name is derived from the word aureus, meaning golden, reflecting the spectacular color of its flowers.

Potential Problems
The primary concerns for growing Aurinia saxatilis revolve around root health and seasonality in challenging areas. Watch for aphids, although they are generally manageable with insecticidal soap or a strong stream of water. The main difficulty reported by gardeners, particularly in the humid American South, is that plants are often short-lived, frequently succumbing to root rot or excessive summer heat stress rather than a persistent pest or disease. Avoid planting in heavy, compacted soils as this guarantees poor drainage and shortens the plant’s expected lifespan.
Frequently Asked Questions

Conclusion
The vibrant, dependable spring show provided by Basket-of-gold ensures its long-term popularity among gardeners seeking low-maintenance alpine and rock garden specimens. The success of Aurinia saxatilis hinges entirely on maximizing drainage and minimizing humidity around its crown, especially post-bloom. Before planting, verify that your dedicated location offers sharp drainage and intense sunlight across your local hardiness zone compatibility.
Companion Planting
When selecting companions for Aurinia saxatilis, prioritize plants that share its preference for dry, lean soil and abundant sunshine. Consider pairing it with low-growing succulents like various Sedum species, which offer textural contrast and thrive in similar harsh conditions. Creeping Thymes (Thymus serpyllum) are excellent companions, filling in around the Basket-of-gold as its bloom wanes, while also offering fragrant foliage throughout the summer. For a contrast in texture, drought-tolerant ornamental grasses with fine blades can work well without competing heavily for resources.
Design Ideas for Rock Gardens
The cascading habit of Aurinia saxatilis makes it indispensable for creating a natural, established look in constructed rockeries. Plant groups directly in the joints or crevices between larger boulders, allowing the stems to drape down the vertical face of the rock. For retaining walls, plant Aurinia saxatilis along the top edge every 12 to 18 inches; this placement facilitates easy post-bloom trimming while ensuring the flowers cascade attractively over the stonework. Avoid placing it near moisture-loving companions, as the inevitable watering required by those neighbors will create an unsuitable microclimate for the Basket-of-gold.
