A popular perennial, used to provide long-lasting colour in late summer and autumn. Plant breeders have been able to produce some excellent compact varieties to replace the old-fashioned sorts and there are double-flowered types now available. But the colour range has not really been extended – the Rudbeckias remain either yellow or orange. The blooms last well in water – flower-heads which are not cut for indoors should be removed once the petals have faded. Add organic matter at planting time and stake theto support the large heads. Cut the plants down to ground level in late autumn.
