How long do stratified Johnny Jump-Up seeds take to germinate?

Can I direct sow Johnny Jump-Up seeds?
Yes! Direct sow in fall (September–November) for natural winter cold exposure and spring germination, or in early spring as soon as soil can be worked. Press seeds lightly onto soil surface without covering. Keep soil moist until germination.
When should I start seeds indoors?
Start pre-stratified seeds indoors 10–12 weeks before your last spring frost date. Keep seedlings in cool to moderate temperatures (55–70°F) with bright light. Transplant outdoors in early spring after frost danger passes.
How much sun do Johnny Jump-Ups need?

What type of soil do Johnny Jump-Ups prefer?
