Stately, attractive, densely foliaged trees that grow at a moderate rate. All have irregularly heart- shaped leaves and small, fragrant, yellowish white flowers in droop- ing clusters in late spring, early summer. Flowers develop into nutlets, each with an attached papery bract. Best in deep, rich, moist soil. In cold-winter areas, fall color varies from negligible to a good yellow. Young trees need shaping, older ones only corrective pruning. Aphids can cause honeydew, which drips disagreeably and encourages sooty mold.
T. americana. AMERICAN LINDEN, BASSWOOD. Zones US, MS, LS, CS; USDA 6-9. Native to eastern North America. To 4060 ft. tall, 2025 ft. wide. Straight-trunked tree with a narrow crown. Dull, dark green leaves to 46 in. long, nearly as wide. Not at its best in city conditions. 'Redmond' is a pyramidal form with glossy foliage.
T. cordata. LITTLE-LEAF LINDEN. Zones US, MS; USDA 6-7. Native to Europe. Dense pyramid to 3050 ft. tall, 1530 ft. wide. Leaves 1123 in. long and as wide (or wider), dark green above, silvery beneath. Excellent lawn or street tree for the Midwest and Upper and Middle South. Given room to develop its crown, it can be a fine patio shade tree (but expect bees in flowering season). Can be sheared into hedges. Very tolerant of city conditions. Selected forms include 'Chancellor', fast-growing 'Glenleven', dense 'Greenspire', heavy-blooming 'June Bride', and 'Olympic'. 'Summer Sprite' is compact, at just 20 ft. tall and 15 ft. wide.
T. x euchlora. CRIMEAN LINDEN. Zones US, MS; USDA 6-7. Hybrid derived from T. cordata. To 2535 ft. (perhaps eventually to 50 ft.) tall, almost as wide. Slightly pendulous branches. Rich green, glossy leaves have paler undersides, reach 24 in. long and wide. Casts more open shade than T. cordata.
T. tomentosa. SILVER LINDEN. Zones US, MS, LS; USDA 6-8. From Europe, western Asia. To 4050 ft. tall, 2030 ft. wide. Leaves are 35 in. long and wide, light green above, silvery beneath; they turn and ripple in the slightest breeze. Good yellow fall color. Takes more heat and drought than most other species and isn't as messy. 'Sterling' has silvery young leaves and an especially handsome winter silhouette.
