I started some Balloon Flower seeds following the instructions on the
pack and what I found online. The seeds were surface sown. The pack and
online sources list 14-30 days for germination, stressing the 21-30 days
part.

Mine germinated in 5 days. Isn't this way off the curve for average
germination time? Anyone else have seeds germinate this quickly for
Platycodon?

Just interested. Thanks.
