Foxglove rewards patience: most varieties are biennials that need a full season of leaf growth before they send up their towering flower spikes, and fall planting beats spring in most zones. Get the timing right and you’re rewarded with taller spikes and an earlier show the following year, rather than a stunted plant that never quite catches up.Gardeners in zone 9 get taller spikes and earlier blooms by planting in fall instead of spring, while zone 7 growers can expect towering spikes by spring from fall-planted varieties. Warmer zones further south only get one season out of foxglove rather than multiple years, which changes how you plan around it and which varieties are worth the trouble. Once the first flush fades, pruning it correctly can coax out a second, smaller round of blooms before the plant sets seed and finishes for the season.Below are zone-by-zone planting guides plus pruning and variety advice to keep foxglove blooming as long as possible.
