Malus x ‘Prairie Fire’ (syn. ‘Prarifire’) – A great choice for disease resistance with reddish-pink buds that open to rich magenta flowers. The leaves emerge a deep purple and shift to a dark bronze green by summer with red petioles. 1/2″ wide reddish-purple fruits are produced which attract birds. Orange fall foliage tones. Grows 15-20′ high by 15-20′ wide. Hardy to zone 4.
Malus x ‘Thunderchild’ – A popular flowering crabapple with abundant rich pink single blooms (from April to May) that emerge from rose-coloured buds. The deep purple foliage is borne all summer and shifts to a brilliant red in the fall. Ruby red fruits (about 1/2″ diameter) are produced and will attract wild birds. Grows 20′ high and 15′ wide. Hardy to zone 3.
Malus x ‘Spring Snow’ – A stunning cultivar with abundant pure white blooms that emerge from shell pink buds. These are borne mid spring and are followed by green foliage. ‘Spring Snow’ is also a sterile cultivar, so fruit drop is never a problem. This is a good choice for small urban gardens or for planting along sidewalk strips. Grows 20-25′ tall by 15 to 20′ wide. Hardy to zone 3.
Malus x adstringens EMERALD SPIRE (syn. ‘ Jefgreen’) – A new introduction with a compact columnar form and crimson buds which open to fragrant pink flowers. It is a result of breeding with ‘Selkirk’, ‘Wijcik’ and ‘Thunderchild’. Small red fruits are produced (unlike the Stark’s ‘Emerald Spire’, which are green). Very cold hardy. Grows 12-15′ tall by 5-6′ wide. Zone 2.
Malus x ‘Royalty’ – One of the best crabapple cultivars for colour with its rich dark ruby red single blooms that are lightly fragrant. These are followed by small deep red fruits that are great for making jelly (it is also self-fertile). The bronze-purple foliage shifts to red in autumn. Prefers a full sun exposure with good soil drainage. Grows 15-20′ high by 20′ wide. Hardy to zone 3.
