CHOOSE TULIPS FOR A REPEAT SHOW
Tulips have a reputation for disappearing without a trace. This is especially true if you grow them in heavy clay soil that becomes waterlogged in winter. However, some tulips are more reliably perennial and will reappear spring after spring, so use these in the gorund and save the fussier ones for pots where you can treat them as fancy annuals. Darwin and Triumph tulips are most likely to reappear. Fosteriana tulip ‘Purissima’ also blooms year after year, and the smaller species tulips, Tulipa sprengeri, T. humilis and T. sylvestris are all long-lived and will slowly spread to form drifts of spring colour. To increase the chances of tulips flowering again, add grit to the planting hole, especially if you garden on clay. Plant hybrid tulips 20cm (8in) deep and smaller species tulips 10cm (4in) deep. Remove seedheads after flowering and allow foliage to die back naturally until it has turned fully brown.
