Tilia americana

Bloom Color: Green, Yellow. Main Bloom Time: Early summer, Late summer, Mid summer. Form: Oval, Pyramidal.

Tilia americana is a deciduous Tree growing to 25 m by 12 m at a medium rate.
It is hardy to zone 3 and is not frost tender. It is in flower in July, and the seeds ripen in October. The species is hermaphrodite and is pollinated by Bees.
It is noted for attracting wildlife.
Suitable for: light , medium and heavy soils and prefers well-drained soil. Suitable pH: acid, neutral and basic soils. It can grow in semi-shade or no shade. It prefers moist soil. The plant can tolerates strong winds but not maritime exposure.

Landscape Uses:Pollard, Screen, Specimen, Street tree. Prefers a good moist loamy alkaline to neutral soil but succeeds on slightly acid soils. Grows poorly on any very dry or very wet soils. Dislikes exposed positions. Another entry in the same book says that it is fairly wind tolerant. Succeeds in full sun or semi-shade. A fast-growing and moderately long-lived tree in the wild, it starts producing seed when about 15 years old and continues for at least another 85 years. It is generally unsatisfactory in Britain, preferring a continental climate and growing more slowly and not usually producing fertile seed in areas with cool summers. Grows best in a woodland situation, young plants tolerate a reasonable level of side shade. They are highly shade-tolerant according to another report. Trees respond well to coppicing, sending up lots of suckers from the roots. Lime trees tend to hybridise freely if other members of the genus are growing nearby. If growing plants from seed it is important to ensure the seed came from a wild source or from an isolated clump of the single species. A good bee plant. Trees are usually attacked by aphids which cover the ground and the leaves with a sticky honeydew. Quite tolerant of root disturbance, semi-mature trees up to 5 metres tall have been transplanted successfully. Plants in this genus are notably resistant to honey fungus. Special Features:North American native, Fragrant flowers, Attractive flowers or blooms. The plant is heat tolerant in zones 8 through 1. .
At this temperature, many plants begin to suffer physiological damage. Heat Zones range from 1 to 12 .
For example Heat Zone. 11-1 indicates that the plant is heat tolerant in zones 11 through 1.) For polyculture design as well as the above-ground architecture information on the habit and root pattern is also useful and given here if available. A sprouting standard sending up shoots from the base . The root pattern is flat with shallow roots forming a plate near the soil surface . The root pattern is a tap root similar to a carrot going directly down .
