R. campylogynum is a dwarf evergreen shrub with small, glossy leaves, glaucous beneath, and open bell-shaped, pale or deep rosy-purple or pink flowers 2.5cm across in late spring
'Hydon Dawn' is a compact evergreen shrub to 1.5m tall, of dense habit, with glossy, dark green foliage with cream felt beneath. Rounded trusses of frilled, pale pink flowers, 5cm in width, which fade to near-white, are produced in late spring
Myrtilloides Group is a dwarf, evergreen shrub forming a low, spreading mound up to 40cm high. Waxy plum-purple, thimble-shaped flowers appear on long stems all over the plant in late spring
E. sessiliflora is an erect shrub, to 2m in height, with upright or spreading, needle-like leaves. Dense clusters of greenish-white, tubular flowers are produced from late winter to spring. Later, the sepals swell, protecting the seeds, to produce red or greenish-yellow fruiting clusters that turn brown and remain on the plant for several years
E. mammosa is an upright, evergreen shrub with whorls of short, narrow, dark green leaves and elongated clusters of tubular flowers in summer and autumn. Flowers may be dark red, orange-red, pink, green or white
'Myretoun Ruby' is a prostrate evergreen shrub to 15cm in height and 45cm wide, with dark green foliage and racemes of deep rose-pink to magenta flowers from winter to spring
'Addy Wery' is a small, evergreen azalea to 1.2m tall, with small, mid-green leaves and abundant, intense orange-red, trumpet-shaped flowers, 4cm in width, in mid to late spring
'Christmas Cheer' is a large, bushy, evergreen shrub with dark green, glossy leaves, paler when young. Pink-tipped, white, urn-shaped flowers appear in long, hanging clusters often starting in winter rather than waiting for spring

'Hachmann's Marlis' is a low, spreading evergreen shrub with slender, dark green leaves, grey-white beneath, and in late spring it produces trusses of white, bell-shaped flowers, to 7.5cm across, edged with deep purple-pink and marked with red
