Aster x frikartii is a popular upright perennial grown for its wonderful display of bright coloured flowers in late summer and early autumn.
Towards to end of summer clusters of daisy-like lavender blue flowers are borne on the top of tall branched leafy stems.
For best effect these are best planted in groups, great in sunny mixed garden borders, they can also be planted in pots and around patios providing they are getting suffiicent sun.
