It makes sense to me from a Darwinian standpoint that flowering plants in an ecosystem may derive an advantage by being triggered to flower if other like species began flowering independent of photo period or temperature related flowering cues. Sort of like Keeping up with the Joneses. I am not aware of compounds that can induce flowering in plants not connected to the same vascular system. There is scientific evidence for a "florigen", though for may years the idea of a florigen molecule apparently was the source of some ridicule amongst plant physiologists. A florigen is a compound that when present in plant tissues can induce differentiation of apical meristem tissues into flowering meristem. In brief if you had 2 identical plants subjected to different growing conditions, one favorable to flowering and one not, taking tissue from the flowering plant and grafting it onto the non-flowering plant can induce "precocious" flowering in the non-flowering host plant. Pretty cool, huh? (Plant physiologists please forgive for any misrepresentation, I am actually better versed in cellular function of things without cell walls) The sand in the Vaseline is that in this case the plants have to have contact with the vascular tissues of, not just be in the immediate vicinity of a flowering plant. Having said that, I do know that ethylene in vanishingly small concentrations can induce fruit ripening, and I have always said my wife's geraniums smell funny...so you may be onto something. Now here is my theory on why my wifes collection of African Violets that had been in non-flowering vegetative growth mode for years suddenly went on a blooming frenzy shortly after the expansion of my orchid collection began to occupy the same space. The AV knew that we had discussed composting them since they had been just taking up space, and the show the orchids were putting on shamed them into a floral extravaganza. As it happens the geraniums that will not die also perked up after the arrival of the orchid grow-cart.

Its called a keiki, and it is indeed a new plant. It can be likened to the baby plants that sprout from spider plant stems. Eventually, probably early next spring, it will have sufficient enough roots you will be able to remove it from the mother plant and pot it on its own. Look under the FAQ's at the very first and 2nd question. They can answer some of your questions.

Beauty comes with experience...:>) Nice to have orchids growing in the trees.

Iguana have become a major pest in South Florida, especially eastern Dade, Broward & Palm Beach counties. A number of years back I was down by Dinner Key during the summer and there were hundreds of them in the turf areas and crossing the roads. Here in Martin County they are just starting to be a problem. They decimated my pole beans for 4 plantings in a row. Iguanas run as fast as a rabbit, climb like a squirrel and swim like a gator so fences and other deterrents don't work. I found the best deterrent is a pellet rifle. We had loads of the lizards at work in PB County, hired a trapper to no avail. they caught 1 but my housekeeping crew let it out of the trap. The little ones you see are newly hatched babies. They bury the eggs underground and leave them unattended. Sorry to say but those quiet little ones will grow up to be 4-6 foot lizards with a voracious apatite for your garden. Besides that they love to swim in my pool & make a huge mess on he roof, pool & patio, Florida Fish & Wildlife Commission, FWC, has said it is legal to kill them year round. I take advantage of that when ever possible. As far as predator's go, occasionally birds of prey, Bobcats or gators take them. At work we had some Latin fellows in a john boat knock the big lizards out of the trees & into their boat for a later meal. Apparently they are tasty if prepared right.
