Crown Princess Margareta has arching stems that can be left to produce a 1.5m high shrub, or trained as a 3.5m high climbing rose. The flowers, produced in summer and autumn, are fragrant, fully-petalled rosettes in apricot-orange
'Blue Eclipse' is a medium-sized deciduous climber, up to 3 metres high, with divided green leaves and large bell-like flowers of deep blue with a white edge on the outside and white inside, followed by fluffy seedheads
'Subpumilum' is a compact deciduous fern to 10cm tall, with glossy black stalks bearing pedately divided fronds composed of fresh green, close-packed oblong segments
'Gerda' is a deciduous shrub or small tree, with deep purple foliage from spring to autumn and flat heads of small, pinkish-purple flowers, followed by purple-black berries
'Maiden's Blush' is a trailing perennial with lance-shaped leaves that emerge pink, becoming green; small white flowers open sporadically through the year, but it is not free-flowering
'Claire Maxine' is most notable for its gleaming, puckered foliage, mid-green, reddening in winter. Flowers are deep pink but sometimes hidden beneath the leaves; flowers mostly in spring with sporadic flowers produced through to October
'Diana Clare' is a vigorous semi-evergreen perennial with narrow silvery-green leaves, lightly speckled with dark green near the margins, and violet-blue flowers from late winter to late spring
N. mutabilis is an upright annual to 1.5m tall with a basal rosette of large, oval leaves. In summer, airy clouds of trumpet-shaped flowers are borne on branching stems changing colour as they age from white through shades of pink
'Millennium' grows to 1.8m, with long stems bearing strongly fragrant flowers 6cm across, the standards deep reddish-purple, the wing petals vivid purplish-red
'Orange Glow' forms a small clump of rounded, palmately lobed basal leaves, with deep yellow flowers 2-3cm wide, sitting above deeply divided green bracts and opening in late winter and early spring
