Caryopteris x clandonensis ‘Worcester Gold’ is a deciduous sub-shrub with a rounded, bushy habit. Its foliage is bright yellow and lanceolate with a simple margin. It bears clusters of small violet-blue, tubular flowers from late summer.

The Caryopteris genus, commonly known as Bluebeard, is native to eastern and southern Asia. Caryopteris × clandonensis was originally created as an accidental cross in the garden of Arthur Simmonds at West Clandon, near Guildford, Surrey in 1930 and went on to gain Royal Horticultural Society awards from 1933.

Caryopteris is derived from the Greek karyon, meaning ‘nut’ and pteron, meaning ‘wing’; referring to the winged fruit. Clandonensis is the hybrid name given to the original cultivar in 1930 referring to its origins in West Clandon.
