An old, vigorous and hardy forsythia, with large leaves (to 13 cm long), primrose-yellow flowers strongly marked with orange at the centre, and – in a continental climate – mahogany autumn colour (Dirr 2009). It was apparently first distributed in the middle 20th century as F. ovata, and may belong under F. viridissima (Bean 1981).

‘Robusta’ is still grown at the Sir Harold Hillier Gardens (Royal Botanic Garden Edinburgh 2022), and is represented in the UK National Collection at Sculpture by the Lakes in Dorset by cuttings taken from a plant in the former collection at Pershore College, which had been received from Webbs Nursery (M. Gudgeon pers. comm.).
