This selection was developed in Finland as part of their willows for biofuels program to reduce their reliance on petroleum. A rather stunning large ornamental willow, Salix 'Aquatica Gigantea Korso' was developed to be ‘extra’. The upright tree grows to 50 ft (15.2 m) if not coppiced; opulent pink to silver male catkins grow to 2” (5.08 cm) long; and its leaves grow to 10 in (25.4 cm) long. A wonderful biomass willow for coarse basketry, biofuels and cut flowers. It needs to be coppiced to encourage rod growth. It is also a great variety to use to build living fences, and large garden structures. 'Aquatica Gigantea Korso’ enjoys damp feet, loves the sun, and will tolerate most soils.
