The limes are stately, medium-sized or large trees with handsome leaves producing great quantities of cream-yellow flowers during the summer. They are successful in any fertile soil, and are magnificent in parkland or in public places, but they are in the main too large for the small garden. However, several species are tolerant of pollarding or hard pruning, and are often used for street plantings or in gardens as pleached lime screens.
Pleaching consists of planting standard or half-standard specimens, 8 or 10 ft. apart, and training the side branches to link together to form a curtain-like screen; any shoots growing forward or backwards are pruned flush to the main stem.
In parkland, for municipal planting, or in the larger garden the following readily available species and varieties are particularly worthy of consideration.
Tilia americana, the American lime, forms a. medium-sized tree with rugged bark on older trees. It is remarkable for its exceptionally large leaves. The variety Redmond is an interesting selection of dense, narrow habit.
T. cordata, the small-leaved lime, is a medium to large-sized European tree of neat rounded habit, bearing comparatively small heart-shaped leaves. The fragrant flowers appear somewhat later than those of other species.
