Ratibida columnifera ‘Mexican Hat’ – A flounced skirt of chestnut petals edged in gold gather round the flower disk—a beaded column of sage green, studded with gold. Grey-green cut foliage catches the light. Easy to grow in regular to dry soils, it naturalizes to create large drifts.
Sow Ratibida columnifera ‘Mexican Hat’ at any time of year except mid summer. Sow onto a moist, free-draining seed compost in pots or trays and lightly cover seed with a thin layer of sieved compost. Seal in a polythene bag or place in a propagator or other warm place and maintain at 20-25C. Keep the compost just moist at all times. Germination should begin to take place from 21-42 days. Reducing the soil temperature at night may help improve germination.
