Dense trees with stately good looks and moderate growth rate. All have irregularly heart-shaped leaves and small, fragrant, yellowish-white flowers in drooping clusters in late spring, early summer. Flowers develop into nutlets, each with an attached papery bract. In cold-winter areas, fall color varies from negligible to good yellow.
Best in deep, rich, moist soil. Young trees need shaping, older ones only corrective pruning. Aphids can cause honeydew, which drips disagreeably and encourages sooty mold.Tilia tomentosa
