Impressively large (up to 15cm) and almost irridescent flowers. Position: full sun Soil: fertile, humus-rich soil Rate of growth: average Flowering period: June to October Hardiness: half hardy Impressively large (up to 15cm) and almost iridescent, the cactus-type flowers of this fab dahlia will really shine out in the border. Their long stalks make them perfect for the vase too, so make sure you plant some extras. Garden care: Before planting enrich the soil with organic matter and apply an organic fertiliser during the growing season. Once the first frosts have blackened the foliage, carefully lift and clean the tubers and allow them to dry naturally indoors. Place the dry tubers in a shallow tray, just covered with slightly moist potting compost, sand or vermiculite. Store in a frost-free place, checking frequently over the winter months.
