Starting Foxgloves From Seed
To grow digitalis from seed here in North Texas , start the foxglove seeds indoorsin August . ( I bulge out mine around August 15th ) . This gives the plants 6 - 8 week to mature before planting out in the garden .
In general , most cold - hardy yearly need to be set outdoors 6 - 8 workweek before the last hoarfrost date and get going by seed 6 - 8 weeks before transplant engagement . Here in the DFW country , the average first frost date is November 21 . This mean that the ideal foxglove seed - starting window is July 21 – August 21 .

Another problem is that spring - imbed transplants do n’t have much metre to show deep roots until summer heat arrives .
The solvent is to buy and plant transplanting in the fall , but it is uncommon to see them in nurseries at this time .
