Starburst (May) Starburst (April) Starburst (August) Starburst Purple colours that change and amaze. £3.30 From a dark red start, the colours in 'Starburst' constantly change and amaze. The two-tone crimson and purple effect is brilliant and we get watermarks later in summer. Grows slowly and is a little mean with its offsets so often in short supply. Howard J.
