Noteworthy Characteristics
× Digiplexis is a sterile, intergeneric hybrid resulting from crossing Digitalis purpurea (common foxglove) and Isoplexis canariensis (Canary Island foxglove). These plants have a basal rosette of foliage from which numerous flowering stalks emerge from spring through summer.
'Berry Canary' is an upright, long-flowering selection of hybrid foxglove that features outwardly-facing, pink-purple tubular flowers with burgundy-spotted, creamy-yellow throats. The blooms are densely held on sturdy, upright spikes that can reach 20" long and emerge from robust clumps of basal foliage. Multiple axillary flowering stalks are produced off of the main clump, creating a long bloom period from late spring through to frost. The blooms are attractive to hummingbirds, butterflies, and other insect pollinators. Mature clumps will reach up to 3' tall and spread to fill a 2' area. Plant patent number PP27607 applies to this cultivar.
Problems
