MORE SMALL TREES
All trees grow best in full sun and well-drained, close-to-neutral soil, unless noted otherwise.

• Goat willow (Salix caprea 'Pendula', Zone 4b). Small weeping tree with showy spring catkins.' Kilmarnock' produces larger catkins, but the variety can be hard to find. Five metres by four metres.
• Tree roses (Rosa hybrids, Zone 7). Hybrid tea and floribunda roses grafted on a tall rootstock. Ultimate size depends on the height of rootstock and vigour of rose variety but it's usually two metres by 1.5 metres.
