Koelreutaria Paniculata, or Pride of India, Golden Rain Tree
This is NOT a laburnum, which some mistakenly call golden rain tree. Lovely medium sized deciduous tree (will reach approx 8M in 20 years) with pinky-coloured spring foliage, golden yellow flowers in summer & papery seedpods in autumn. Fully hardy to approx -15C. Prefers moist but well drained soil, best in full sun.
Currently approx 2ft tall in a 7.5litre pot, garden or pot-ready
