I have nearly all the seeds/bulbs I want for this year.

I have:

Coleus (Chocolate Covered Cherry, Chocolate Mint, Watermelon, Picture Perfect Red)
Impatiens (Salmon Splash, Candy Box, Cherry Splash)
Lobelia, Vulcan Red
Nasturtium, Double Gleam Mixed Colors
Sunflower, Crimson Blaze
Penstemon, Carillo Red
Poppy, Oriental Poppy Mix
Sweet Pea, Eckfords Finest Mix
Morning Glory (Celestial Mix, Zeeland Hybrid Mix)
Vinca (Merry Go Round Red, Merry Go Round Grape)
Caladiums, Tropical Mix
Four O'Clock, Marbles Mix
Oriental Lily, Stargazer
Gladiolus (Arabian Night, Firecracker)

I think this will be a good collection if planted right and mixed well together.

Anyone have experience with any of these?

Nice Selection. We do a lot of the same plants/bulbs up here in Washington. but a lot of the plants on your list don't survive the 8 month stretch of October through May. non stop cold and wet, such as the coleus, impatiens, and the caladiums, so we just buy new ones each spring. lilies are tough as nails however and never rot. even if we leave them outside in pots for the entire winter. they always come back bigger and better! so of course we have about 200 of them! haha

Hi lucky, that is a nice list! But I don't do seed level.

But from your list, I have tried to grow some coleus and some caladiums in containers. They do thrive here during our hot summer months, just got to water them frequently, especially caladiums, really thirsty here once fully awake, I have to water everyday. Love them really, since by summer most of my plants are just hanging on when it starts going into the high 90's to triple digit dry heat. I like to pinch back coleus so it will grow bushier.

I find caladiums really slow starters, like they will wait till June to show up or some even waits till July already, maybe because my garden is just too shaded by shade from the city trees, though they will need the good shade with our onerous dry heat.

Coleus is faster though to feel the temperature cold of Fall, so it is faster to die down. Caladiums stays around a bit longer, and I brought the containers inside this winter. Will see how fast it will try to come back when I bring them out again when temps go stable and warm.
