Colt is not a Mahaleb cherry but a hybrid of Prunus avium and Prunus pseudocerasus. It produces semi-vigorous to vigorous, well-anchored cherry trees and is compatible with nearly all cultivars. Colt tolerates heavier and wetter soils better than Mahaleb but is less drought tolerant and less winter hardy. It remains too vigorous for containers or genuinely small gardens.
