Thanks to Cinderella crabapple's dense and compact habit—and its ability to be grafted atop a trunk to form a standard—the tree is ornamental all year round. It isn't just a delicate beauty in Spring when once again in foliage, then bud, then flower; nor just a stalwart sculptural presence in Winter when displaying snow and ice. There's a distinct show even in Summer, when the tree is just in leaf.
The green foliage and casually rounded canopy are shown off particularly well, as here, in the company of plants with wilder habits as well as shocking colors. Cinderella is as party-ready as my topiary of hardy orange, and for the same reasons: Each season, its performance features something both attractive and radically different from what was on display the season before. Both are essential to any garden aspiring always to be nothing less than lively.
