Both increase readily from offsets and grow well naturalised in grass provided the daffodil-like foliage is allowed to die down naturally. The kaffir lily, Schizostylis coccinea, which blooms from September to November is another adaptable and usefully variable species. It requires fairly moist, rich soils to give of its best and then produces masses of its gladiolus-like spikes of open, bright red or pink flowers until the frosts finally deter its impudence. Various named clones are available, all apparently hardy and prolific, rapidly forming clumps by sending out short, couch-grass-like rhizomes from the main corms to form new corms at the tips. One of the most elegant of border plants is Dierama pulcherrimum, the "angel's fishing rod", with graceful, arching 4 to 5(1.25 to 1.5m) stems and pendulous, bell-like flowers varying from deep wine-red through purplish-pink to white and surrounded by silvery, papery bracts. Easily raised from seed, D. pulcherrimum produces narrow, wiry leaves which are virtually evergreen so the corms should never be allowed to dry out completely as this may cause the foliage to die back and weaken them. The fine selected colour forms raised by the Slieve Donard nursery in Northern Ireland and named after birds, sadly, have disappeared from the nursery lists but are well worth obtaining if the chance occurs. Dieramas generally sulk if transplanted when mature and prefer to be left alone to form strong clumps which are also able to resist better the occasional very severe winter that may otherwise betray their South African origin. Bulbs for warm borders Borders which are situated under south- or west-facing walls suit many bulbs requiring a warm microclimate to flower well out of doors in Britain. From September to November the beautiful, funnel-shaped, bright pink and white, delicately scented blooms of Amaryllis belladonna appear. It flowers most freely when the bulbs are subjected to a warm, sunny, dormant phase-not always possible, of course, during the British summer. As active growth begins it should be given ample water and in poor soils a sprinkling of a balanced fertiliser such as Growmore, annually, applied as the leaves start to develop. If the only results of your labours are luxuriant leaves and no flowers, a dressing of potassium sulphate at j to ioz per sq yd(i4 to 25g per m2) or a high potash fertiliser applied at the beginning of leaf development and thoroughly watered in should redress the balance. This is a treatment that is often helpful in inducing non-flowering plants to bloom. 'Hathor', an uncommon white-flowered clone, and 'Kewensis' with deep rosy-red, white-throated flowers, are fine selections occasionally to be obtained in addition to the more usual pink-flowered forms but regrettably they seldom appear in trade lists. Flowering over the same period is Nerine bowdenii, prolific of increase and apparently hardy throughout Britain although blooming most abundantly in warm sunny positions.
