This dainty spring bloomer is perfect at the front of sunny bordes. Covered with blooms early in the season, it will often rebloom if old flowers are removed. PPAF Ths fun Tickseed has blooms that open a rusty red then do a complete turnaround as they mature into a creamy yellow. Unlike other red flowered Coreopsis, "Redshift" is very cold hardy, surviving winters as far north as zone 4.
