Sedum oreganum - Stonecrop

Sedum oreganum, also known as Oregon stonecrop, is a small perennial ground cover with charming miniature foliage. Its plump leaves form small green rosettes that turn red throughout the seasons. Evergreen and capable of colonising even the most difficult terrain, its long stems easily take root in any crevice and thrive in poor and dry soil, preferably in full sun. Its yellow flowering, in a multitude of stars, is a boon for insects during July.

Belonging to the Crassulaceae family, this stonecrop thrives in the wild on rocky slopes in northern America and can tolerate poor, dry soil and high altitudes. It will grow in poor, rather dry, stony, rocky, or even slightly chalky soil. It withstands temperatures below -15°C (5°F), requires no maintenance, and promises to bring your garden to life with visits from butterflies. Sedums are easy-to-grow succulents, with flowers and foliage in various shades that can be used to create stunning compositions, whether in flower beds, pots, or rock gardens. However, they should not be exposed to excess moisture in winter, nor should they be covered in dead leaves (as this can cause them to wither). They prefer a sunny, even scorching, exposure and will thrive in just a few millimetres of substrate.

Sedum oreganum has a creeping habit that can reach a spread of 45cm (18in). Its creeping stems slightly straighten at their tips, reaching a height of barely 5cm (2in). They bear small, flat, spatulate leaves with rounded edges, filled with water. These leaves measure only 3 to 4mm. Alternate in arrangement, they appear as small rosettes at the tips of the stems. This foliage displays distinct but changing shades. Light green, it turns a rosy red that gradually spreads to all the leaves with hints of brown. These nuances, like those of most of its cousins in the same genus, vary depending on climatic conditions: the amount of light and water either lighten or intensify the colours. From this carpet, a vibrant and delicate flowering stands out. Its miniature corymb inflorescences are made up of multiple star-shaped yellow flowers, highly sought after by insects that constantly buzz around them. They can double the height of this small carpet.

Sedum oreganum is a great choice for conquering every corner around the house. Plant it at the edge of a patio, at the base of a wall, or in pots that you can move around according to the seasons. It combines easily with all rockery plants, requires no maintenance, and colonises neglected spaces (making it suitable for green roofs). For a long-lasting flowering period, pair it with Iberis sempervirens (spring flowering) and Origanum rotundifolium 'Kent Beauty' (from July to October). Vary the foliage effects by colour or shape with other sedums: S. spurium 'Variegatum', S. spathulifolium 'Cape Bianco', and S. reflexum 'Angelina'. These easy and carefree miniature perennials are decorative all year round.
