not sure about over where you are jerry,
but i saw a doco' on a large flower plant nursery over here, they grew
chrysanthimums for mothers day, the potted plant that is not the cut
flower. and they had their shade houses set so they could regulate the
amount of light and dark the plant got , this they said fooled the
plant into flowering when they wanted it to.
so guess if you research the plant you like and give it what it wants
it will flower too?
