AS much as is I was only here to see and hear about what some of you might be starting for fall or the plans you have for winter and next spring with your seedlings I have a many a little seedling started ,my favorite being the daylily from my own seeds. I have several Hibiscus to add to next years late summer and fall blooms.I'm looking forward to some more of the red blooms that bring Hummingbirds.
I didn't do well with the Agastache and Pentsemon seedlings, those turned out to be a little more difficult than I hoped for. Yarrow and Hibiscus turned out to be easy to grow and I am really glad of that, I just thought you all might be willing to talk about some of the seeds you have all been trying. Be back later.
I found Penstemon and Verbascum seeds to be quite easy but haven't had luck with any Daylilies. Not one germinated for me. I gave up after 5 months and dumped the seeds out in the garden. We'll see what happens next year. Coreopsis lanceolata and C. tinctoria are easy but invasive. It's a good thing they're also easy to ID and pull. I managed to get Actaea racemosa, Black Snakeroot to germinate but lost it from lack of attention. I want to try it again.
Others with which I've done well are Morning Glories, Cosmos, Perennial Dianthus, Hollyhocks(Alcea), Columbine(Aquilegia), Bachelor's Button (Centaurea cyanus), California Poppy (Eschscholzia californica, also invasive), Gaillardia and Sunflowers of many different kinds. I know there are more but I can't think of them right now.
The seeds of many (most?) Penstemon species require stratification to break down germination inhibitors, so many people do find them difficult... Verbascum are usually easy germinators though.
Kwanjin, wow, you have a very strict personal definition of "invasive"... ;-) I've never heard anyone refer to those native species as "invasive" before, though of course, they do seed themselves... but you'll find that virtually all plants do. (N.B. Your Dianthus photo is of Dianthus barbatus, which is actually a biennial... though hopefully it will reseed for you.)
I've been accused of over-using 'invasive' before. In my yard, the ones I mentioned reseed everywhere. And I do mean everywhere and profusely. And yes, I meant Dianthus barbatus. I've had a few plants for 3 years now and they are producing seeds. Lots of them... The CA Poppies are still coming up in places I don't want them after 3 years of pulling them. We won't even mention the Morning Glories.
Annual and perennial Flax, Linum usitatissimum and Linum perenne, respectively, do well for me, also.
rustylove2_Do you have access to the propagation forum? usually there is advice to be had there,
While I am here , I missed the stratification of Penstemon ,I missed that altogether. Explains the fail mostly.
