Rudbeckia hirta 'Irish Eyes'
This is a gorgeous half-hardy, short-lived perennial which will produce big single golden-yellow flowers with an unusual green eye, or cone, in the centre. Fabulous colour all summer long, especially if deadheaded regularly. Best treated as an annual in colder areas. Full sun to part shade. Flowering height 60-80cm x 30-40cm wide. Plants in 9cm pots...I've checked their roots and they're already at the bottom of the pots so ready to go!
