Abstract
A new and distinctive cultivar of little leaf linden, botanically known as Tilia cordata is provided. The new cultivar exhibits a more rapid growth rate than is commonly observed in the species, exhibits superior winter hardiness in northern zones, and exhibits good foliage disease resistance. The crown is moderately pyramidal in configuration, and the trunk is sturdy and well resists sun scald. Flowers are formed in abundance, but lead to the formation of a sparse seed crop. The new cultivar is particularly suited for use as an attractive landscape planting and for use in areas where a distinctive shade tree is desired.
