Neal: yes, I did start a few lg. carnation plants from those leaf buds on the stems of the cut flowers...but they require an inordinate amount of staking...which is fine.
I don't know where in Ca. they grow cut roses...it must be up north somewhere and they're probably (???) grown in greenhouses...just my assumption.
When I was a kid, we had a HUGE stephanotis vine in our yard. My mother knew the woman who owned a local flower shop and she would come and gather the blooms in the summer for weddings. There were thousands of them at a time on that vine and the fragrance was intoxicating.
I didn't know you were a flower designer. Wish I had a way of posting a photo of my mom's wedding bouquet from 1946. It's just a black and white photo (obviously) but the thing was ginormous! We found their box of wedding planning "stuff" and in it was a piece of paper she had wriiten down the names of the flowers in that bouquet. This was pretty interesting...it had tuberous begonias, bouvardia, roses, FUCHSIAS, lily of the valley, stephanotis, crocus, carnations, orange blossoms, sweet peas, maidenhair fern and about 200 yards of ribbons hanging down. It looked pretty typical of things from that era...but it was so huge it was almost bigger than she was !
