Oxalis Adenophylla (Silver Shamrock)
Oxalis adenophylla, often affectionately known as "Silver Shamrock" or “Sauer Klee” (Sour Clover), is a small but striking addition to your garden, offering charm that belies its diminutive size. This perennial bulb produces low, spreading mounds of delicate, silvery-green, fern-like foliage, which remains attractive throughout the growing season. In spring to early summer, it bursts into bloom with exquisite pale pink to soft lilac flowers, each adorned with darker veining and a glowing white throat – a design as if painted by hand.. Growing to a height of just 8-12 cm (3-5 inches), Sauer Klee is a perfect choice for rock gardens, edging paths, or planting in patio containers where its intricate beauty can be admired up close. It’s also ideal for gravel gardens and other well-draining spots where its subtle foliage and vibrant blooms can shine.. A Rare Detail:. What sets Oxalis adenophylla Silver Shamrock apart is its extraordinary resilience and adaptability. Despite its delicate appearance, this oxalis is remarkably cold-hardy (down to -15°C or lower with good drainage), making it an excellent choice for UK gardeners in cooler regions. Its bulbs have an almost star-like form and are uniquely shaped to anchor themselves in sandy or stony soils, a natural adaptation from its South American origins in Chile and Argentina.. Another rarely mentioned feature is its ability to thrive in alkaline to neutral soils, a trait that makes it versatile for various planting conditions. Over time, it naturalises gently, forming small, tidy clusters that return reliably year after year without taking over.. Botanical name: Oxalis adenophylla.
