The buds swell into large, angular balloons before opening out to produce saucer-shaped. These blooms are about 2 in. across and long-lasting – Platycodon is an interesting and attractive flower which should be more widely grown. Finding a suitable spot should not be difficult – it has no special soil requirements and will tolerate light shade. Mulch around the young shoots in early summer and cut back the in autumn. It does have one problem – all the top-growth disappears in winter and the new shoots do not appear until late spring. It is therefore easy to dig up when cultivating the border and a plant label next to the clump will warn you to steer clear.
