I think you are pampering these too much. Remember, P. incarnata is a weed, and can grow in very poor soil. Throw them in some dirt. Seriously, you should have no problem moving them to bigger pots. If they have been in a very humid environment, you may want to gradually expose them to drier air over a few days.

I made the mistake of tossing some fruit into my compost bin last year. I now have hundreds of these things coming up around every plant that got compost this spring.

Wow u really Lucky i bought many seed for passion and they never sprout for me u know who u bought them from might give them a try the seeds had to be really fresh to sprout so soon. angie

Angie - I bought them on EBAY from "rickattheauction". Looks like he sells a lot of different things. They were advertised as fresh. I am really surprised by the results. Also bought 35 P. Caerula seeds from another source and haven't had any germinate yet. Good luck - MP

I have found that the fresher seed sprout the fastest. I do not clean my seed or do anything else other than removing from the fruit and putting in warm moist potting soil. I have gone the soaking route with orange juice, milk, and several other things with poor luck but with fresh seed you will usually get really good germination and fairly fast.

Kiwinut - Thanks for the advice. Probably pampering too much. Rolled down the tent over a couple of days and put in morning sun. They are taking off now. Also, got my first P.Caerula to germinate yesterday. - MP
