What it's good for, and what it isn't

A large, fast-growing lime with strikingly big dark green leaves, up to 20 cm long, and fragrant pale yellow flowers in early summer that bees visit in huge numbers. It is a shade-giving specimen for big gardens and parks with deep, moist soil. It copes poorly with hot, dry summers and with compacted or paved ground, and aphid honeydew makes cars, benches and paving beneath it sticky.

Watch out for

Aphids colonise it regularly: the dripping honeydew leaves a sticky film on which black sooty mould grows, so do not plant it over a parking space or terrace. In the hot, dry summers of Central Europe it is sensitive to heat and soil compaction, the leaves may scorch and spider mites can build up. It copes poorly with polluted city air and with paving. Verticillium wilt is rare but can be fatal.
