| Growing Guide & Production Protocols | Silene X robotii, part of the Caryophyllaceae family, is known for its compact, mounding habit and intensely bright, long-lasting flowers. This herbaceous perennial thrives in full sun to partial shade, well-drained, consistently moist soil. With strong blooming performance and tidy growth, Silene X robotii blooms from early summer into fall, making it a favorite for border fronts, rock gardens, and mixed patio containers that need vibrant, uniform floral cushions. |
| Cultivation & Groweing guidelines | Establish early at 65-68°F (18-20°C) to bulk. If bulking for spring sales, many varieties benefit from dropping temperatures to 40-50°F (4-10°C) for vernalization. pH 5.8-6.2, EC 1.0-1.5, feed 100-150 ppm N. Allow media to dry moderately between waterings to encourage deep root systems. Fungicide drench recommended at transplant. |
