Flower - Scleranthus Uniflorus - Knawel Cushion
This is probably the most diminutive, slow-growing and intriguing ground-covering alpine plant one can grow. In early summer, the prostrate cushion makes tiny half inch stems which carry one golden seed each, whilst any weeds in its path are stifled.
Seeds are best sown in winter or early spring as they benefit from a cold spell in the wet compost after sowing to break their dormancy. They may also be sown at any time, and if the seeds do not come up within 4 or 5 weeks, the damp seed tray can be given cold treatment in a fridge for about four weeks. These seeds may still take several months to appear, so please keep the pot or tray safely.
