Paul, perhaps you'd say a few words on germination of Platycodon.  My plants,
tall ones and a few dwarfs set seed.  The seed never germinates outdoors on
it's own.



I have never had seedlings under my plants ether-but my beds are crowded-like most seed I am sure that germination is better after the seed dries.  Under normal garden conditions the seeds might be eaten or they root away before they dry properly or they suffer a drought during that critical first three weeks of life.

I just started some old seed from Platycodon 'Sentential Blue' and the seed germinated in 6 days with 85% germination rate, the seed is three years old.

Platycodon is one of the easier plants to start from seed-surface sow the seed-it needs light-and keep at F 75.  I seal up the pots in a large bag to keep the humidity high until all the seeds have sprouted.

The larger types do not bloom for at least a year, though there is a selection that is supposed to bloom the first year-still working on acquiring those.  The smaller types are said to bloom the same year too.

I have a few double white plants for this year-and will be starting 7 selections of Platycodon for next year, I like the larger plants myself-but there are more and more smaller types coming on the market for bedding and pot culture.
