Heuchera ‘Thomas’ (Fox Series). Flowers are borne on unusually tall stems that rise more than 2ft above the plant. ‘Thomas’ is named after the grower’s son, who is a former England junior basketball player. The flowers consist of large open bells (large for heucheras) that are cream with green markings which, when in bud, resemble ears of corn. Introduced at RHS Chelsea in 2013.
