Update:
Thanks to Leni's sending me some seeds, I have just harvested (yes, October 20th!) my first Fleur Peppers!
I started the seeds indoors on May 5th, five germinated and I planted the small plants outside in the middle of June.
They took all summer to flower (I do not have 10-12 hours of sunlight) and I'm just getting the little peppers now.
They are large plants with zillions of flowers and teeny peppers now. Much larger and more slow-growing than the Wrinkled Old Man Peppers that Leni also sent me.
There was chance of a freeze last night, so I covered the plants with gardener's fabric, and will leave that on, hoping to get more peppers before winter.
I've only eaten one so far, and it's not at all hot. I've read that you can occasionally get a hot seed, though.
Leni, do they get red or black if you leave them on the plant long enough? Have you pickled them?
Next year I will definitely start the seeds earlier and place them in the sunniest spot.
Such lovely peppers - thank you again, Leni!
