"Once a pollen grain settles on a compatible pistil, it germinates in response to a sugary fluid secreted by the mature stigma. Lipids at the surface of the stigma stimulate pollen tube growth for compatible pollen. Plants that are self-sterile inhibit the pollen grains from their own flowers from growing pollen tubes. The presence of multiple grains of pollen has been observed to stimulate quicker pollen tube growth in some plants. The vegetative cell then produces the pollen tube, a tubular protrusion from the pollen grain, which carries the sperm cells within its cytoplasm. This tube is the transportation medium of the male gamete to reach the egg cell.
The germinated pollen tube must then drill its way through the nutrient-rich style and curl to the bottom of the ovary to reach the ovule. Once the pollen tube successfully attains an ovule, it delivers the two sperm cells with a burst. One of them fertilizes the female gamete (the egg cell) to form an embryo, which will become the future plant. And the other one fuses with both polar nuclei of the central cell to form the endosperm, which serves as the embryo's food supply. The endosperm is rich in starch, proteins and oils and is a major source of human food (e.g., wheat, barley, rye, oats, corn). Finally, the ovary will develop into a fruit and the ovules will develop into seeds."
Even the seedlings have hair!
It surprised me in many ways.
I encourage plant rescue! The life you save may bring you lots of good photo ops.

I patted down the soil a bit.
Had my work inspected.... This is very important!
Some plants that produce tubers or rhizomes like a moist soil for growth, but you have to pay attention to their needs and see that they don't stay too wet, otherwise tubers rot.
What would a set up like this likely do? This might keep the plant extremely well drained but allow the roots to take up all the moisture they require from a soil mix that might otherwise be considered "heavy" for what you're planting.
So??? Will this work??? Have you tried it on other things??? I'd love to start a discussion...... Comments?????

Patty says, "This is the first bloom from my 'Noreen'. I think it's still sort of small but since it's still alive, I'm improving (on Strep growing)."
"It's not been repotted yet, it's growing in my shelf in the coolest room beside my cold growing orchids and it's not in a dome. I'm bottom watering it once a week and fertilizing maybe every 2 weeks."
So, again.... comments. Note that Patty's flower has much more defined lines and stripes and the yellow of the throat patch might be darker too. Why?
The ruler on the first photo is 12" long. The plant I took home is now somewhat larger than a foot and has approximately 9-10 leaves. I'm somewhat hopeful that it will be in bloom for the spring show in three weeks.
The next post will show Patty's flower that has much darker striping in the lines and webbing of the flower.
I tossed out a whimsical theory about this particular plant's genetics that I would like some comments on. I hybridized this plant some years ago. Most of the seedlings weren't quite this pretty and every other plant from that cross is now extinct as far as I know. I really liked the color of this one personally and enjoyed growing the plant. When I switched plant-rooms and added four foot T-8 lights I had a bit of a disaster. A hot summer combined with a very hot room ruined most of the plants I was growing and indeed killed off the parent to this plant. Fortunately, Dennis had taken just one little leaf and propagated it. I purchased some of the babies back from him and then I got enough of the future babies to pass out as a club project. I don't usually have extraordinary luck with Streps in general... sure they grow, but I forget to water them blah, blah, blah.... but this one - at my house - always looks pretty fresh, grows fast and tolerates some abuse.
I've heard that people find that plants hybridized in their general geographical location do better for them than plants hybridized in very different locations. For instance, Texas hybrids don't really like MN winters.... MN hybrids don't do well in Southern state's really hot weather etc. So, what I'm saying is: Does 'Noreen' do well for me because it was the one to survive my particular set of conditions and my sort of plant-abuse?
The one baby that went to the CBS greenhouse is reportedly exactly the same size as when it was passed out. Others have said that their plants aren't really growing all that well. I am thrilled that my plant is jumping out of the pot and is over a foot across. I do know that I'm trying pretty hard not to humiliate myself and kill off the project plant that I thought was such a good experiment, but I'm not really babying it either.
