Malus ioensis 'Plena', the Double-Flowered Crab Apple, is one of the most spectacular ornamental flowering trees for cool to temperate Australian gardens. Masses of fragrant double pink blossoms cover the branches in late spring, held in dense clusters that resemble small roses and last for weeks longer than single-flowered crab apples.
Malus 'Plena' grows to 5-7 metres tall and 4-5 metres wide with a rounded spreading canopy. The compact garden-friendly size, fragrant spring display, and golden-orange autumn foliage make it an excellent feature tree for residential gardens, courtyards, and pollinator-friendly planting schemes. Unlike fruiting crab apples, this cultivar produces very sparse fruit, keeping it clean and low maintenance.
Malus 'Plena' performs best in cool to temperate regions including VIC, NSW, ACT, Tasmania, and elevated parts of SA and WA. It needs cool winters for reliable spring flowering, performs well in a wide range of soils, and is low maintenance once established.
Also available as a standard. The Standard Form is grafted at 1.8 metres, giving a clear straight trunk with the flowering canopy carried well above head height. It suits a formal avenue, a driveway or a courtyard where you want clear space and planting underneath the tree. Every other size on this page is the natural branching form.
