‘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
‘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.
