On my drive to work each day, I pass by many wildflowers along the side of the road. Many I would like to have in my meadow at home. They will soon be mowed down by the road crew. My question is, would I get the same seed production by taking a cut flower and putting it in water and allowing it to do it's thing in a vase or are there other factors?
Most flowers are pollinated by insects. So if you cut some, take the ones who already bloomed and put them in a vase until their seeds are ripe.
If all are still blooming, put them in a vase and leave the vase outside, somewhere where insects come frequently.
It depends on the kind of wildflower wheather it will set seed in a vase or not. Some flowers need months to let their seed ripen and you won't achieve that in a vase.
So I strongly advice to take the most faded blooms or (better) the ones who already started to set (unripe) seed. I hope this is clear, because English is not my motherlanguage.
Since you're in zone 5, may I ask you if you're interested in trading seeds. I'm only interested in seeds of wild plants, so no hybrids. Please have a look at my website to see if there is anything on it that interests you. ALL my seeds are available for trading.
Jonna, everything in my yard is covered in bees, so I doubt I'd ever get seed from anything that isn't hybrid. Sorry about that, because I'd be interested in trading. I'm also just about full, as far as yard space goes!
