‘Covey’ a.k.a. Lavender Twist® - An interesting weeping form with contorted stems. The plant will not grow more than 5 feet tall without being staked. Two are planted at Fraternity Row and a new installation is to the south of Marie Mount Hall. ‘Forest Pansy’- Similar to straight species but has a red pigment to the leaves. When planted in sunnier locations this tree will have redder leaves while shadier locations will have leaves with more of a green tint. This cultivar is located to the west of Symons Hall, and to the east of Mitchell Building. ‘Oklahoma’ – Although this cultivar is often listed as C. reniformis it is strikingly similar to C. canadensis and may be a botanical variety. The notable difference is extra glossiness of the leaves due to a thick waxy layer. There are four planted in the Chemistry Courtyard Garden and a straight species C. canadensis is planted among them, providing an interesting teaching comparison. ‘129EC’- This selection of C. glabra is used for research by our Plant Science department and the National Arboretum due to its ease of micropropagation. A select group was “brought out of tissue culture” and planted at the Peace and Friendship Garden which is located between UMUC and the President’s Residence.
