('Schubert' choke cherry) Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

'Schubert' choke cherry has a pyramidal form and vivid foliage that makes it a great focal point. Abundant, dark red-purple fruit follow the ephemeral, light pink flowers. The fruit is attractive to birds, so 'Schubert' choke cherry should not be planted near patios or walks due to the calling cards well-fed birds leave behind. Ask if the tree you buy is grafted onto nonsuckering rootstock; otherwise, suckers could pose problems down the road.
