The optics of the seeds
If you harvest the seeds yourself from the seed pods or buy a seed packet, you’ll see it for yourself. Foxglove seeds are:
- tiny (less than 0.5 mm)
- somewhat elongated
- all different in appearance
Internal characteristics of the seeds
What is not visible from the outside are the inner features of these seeds. Therefore, before sowing foxgloves, it is good to learn about the peculiarities of its seeds.
Usually, the seeds mature properly in the spring after spending the wintertime on the ground. Their good germination becomes clear if you leave the foxglove to itself. New plants appear every year as the seeds like to sow themselves.
The seeds do not necessarily have to be exposed to a cold stimulus (stratify). They germinate best at temperatures between 15 and 18 °C (59-64 F). But be careful: they need light to germinate!
When and how are the Foxglove seeds sown?
The seeds are best sown in a targeted manner at home in spring (alternatively in a cold frame with a cover) or in summer. Pots and bowls, among others, are suitable. As a surprise to unknowing gardeners, the seeds tend to self-propagate.
You should spread the seeds superficially (no deeper than 3 mm below the ground). A sand mixture is recommended for even distribution of the seed. Press the seeds down and give them and the soil plenty of water.
If you sow the seeds in the bed in summer, make sure to water several times a day – if there is no rain -. Otherwise, the seeds will dry out quickly and will not germinate. A garden hose with a fine nozzle should be used for watering so that the water jet does not press the seeds too hard into the soil. Sprinklers are also well-suited.
Be patient. It can take anywhere from 14 to 30 days for the seeds to germinate.
