flowerbed update & seed question

just another update on our flowerbed....it's coming along great, now that we've been keeping the weed situation under control ;0)

we still get blooms here & there (unfortunately, not all at the same time!) - and the girls & i love finding new ones getting ready to pop open, then figuring out which flower they are & what seed they came from

here's what it's looking like today - some of the flowers that came from bulbs have gotten too heavy & fallen over - luckily, after we got to enjoy their blooms....
some of the wonderful blooms we've had over the summer....

and a new thing we've discovered - the production of seeds, after the blooms dies & falls off....it's been soooo fascinating for the girls! and it's nice that these flowers (the bright pink & orange ones above, right under the poppy) are the ones that are producing the seeds - they're also the plants that have bloomed the most.....of course, we plan on planting more next year in addition to what's already there - we're hoping to FILL IT UP eventually! ;0)

first it looks like this after the bloom dies....
then it dries up & looks like this - this is when you can pull off the long, black seeds....now my question for you - i know that the seeds would probably fall off on their own & reproduce.....but should i save these until next spring/early summer? or should i plant them now? (remember, i soooo don't have a green thumb!)
