I thought my hosta were a bust too, but they just started coming up this week in my zone 5. My siberian iris I ws'ed last year had very eratic germination too. When I planted them out this time last year they looked like just little blades of grass. Now they are big and sending up flower stalks which I thought would take years. Siberian irises are definately worth the wait. Doesn't flower for long, but the foliage looks good all season.

My hosta are just starting to come up too.

I get another hosta about once a week. I've got almost 2 dozen so far between two containers. And it's been hot here. Just wait a bit if you can. They should start popping up any time.

I was wary of my confederate rose. I checked today after moving them into full sun a week ago. I have 8 sprouts now instead of the one single sprout I've had for weeks. Some seeds just take longer than others.

Passiflora, I only got one seed to germinate from a purchase package of 8 seed. That one plant is now 3' tall and twining around a small trellis in a pot.

I only have 1 sprout from Passiflora and I am not even sure thats what it is! Does not look like any of the Google images. I have about 10 containers with zero germination, but over all I would say my results were very very good.

I'm in zone 6 and while most of my asclepias have germinated, the whole jug is still working away.

Deanna, I've found I'll get really erratic germination from just about all iris including siberian if I straight winter sow. The last time I put a pot out in winter, it was 18 months before they quit germinating - I'd call that erratic :), that pot had seedlings of all ages in it.

They self sow in my garden, so I began either Fall sowing, or putting the seeds in a tiny bit of moist vermiculite on my desk (little zip lock) for a few weeks to give them some warm moist time before winter sowing them. Problem solved.

Morz8, thank you for that info. I will try that next year.

As far as plants (like hosta & iris) slowly continuing to germinate, won't it disturb the seeds if I remove the germinated seedlings?

6 Siberian Iris isnt a bust, that would make a fairly nice clump, once established they can spread.

Hosta 3 years in a row with no germination.. I just had 3 days of 80 degrees and nothing, I just dumped them. I usually wait untill june 1st, but we are having a bbq monday , I had 20 or so jugs with nothing in them, kept the japanese maples and dumped the rest to tidy up a bit.

Ive had mixed success with malva, one year I had one lonely one =(... This year Like 8 (yeah)

They key to wintersowing is you can do lots , I did well over a hundred this year, so even with 20 no germinations, I still had over 80 to plant out =)... next year sow sow sow!
