When to plant foxglove in zone 7b

|---|---|
| Direct sow / transplant outside | Apr 17–Apr 24 |
| Estimated bloom | Apr 16 '28–Apr 23 '28 (~365 days after transplanting) |
Spacing: 1 per square foot (square-foot-gardening spacing). Mature height: 2-5 ft.
Foxglove produces some of the most dramatic flower spikes of any garden biennial, tall stalks lined with tubular, often speckled blooms. It's also the source of digoxin, a real heart medication, which is a way of saying every part of this plant is toxic if eaten, not just mildly irritating.
How foxglove fits zone 7's season
Zone 7b's frost-free window runs about 198 days, from April 10 to October 25. Foxglove needs about 365 days from transplant to first harvest.
