Winter Lemon Arenaria

Arenaria montana ‘Winter Lemon’ is Syngenta Flowers’ compact, yellow-flowered sandwort (product 70074119). The grower describes it as a mounding perennial for small containers, flowering from early through late spring and requiring little chilling for production. ## Landscape Use and Seasonal Interest Syngenta’s [Winter Lemon profile](https://www.syngentaflowers.com/ams/product/flower/70074119) identifies the exact variety as yellow/gold, compact to medium in vigor, and 4–6 inches tall by 10–12 inches wide. Its low mound fits rock gardens, borders, and containers, especially alongside other early-spring perennials. Allow enough space for its wider mat rather than treating it as a tiny upright accent. ## Siting and Soil The product is listed for full sun to part shade and USDA zones 3a–8a. The RHS guidance for Arenaria montana recommends full sun and poor, freely draining soil; partial shade is also given for related commercial cultivars. Keep the root zone well drained, particularly in winter. ## Maintenance Water consistently while establishing, then avoid keeping the soil saturated. The RHS reports no routine pruning is required for mountain sandwort; clear damaged foliage if needed.
