Here are a couple (one is with callibrachoa). They could obviously use some pruning/shaping. These aren't the big ones, but I snapped the pic because I liked it.

I once tried overwintering geraniums in the basement, too, never again. Now they live in a bright window, in a cool room. Summered outdoors.
My family are used to plants being all over the house..I tell them, it's to beautify our home..LOL..good enough reason...Toni

I found them at a local nursery last spring, and they were small little guys at the time. I started calling nurseries all around my area that winter to see if they were going to carry them Otherwise, I would have ordered some seeds.

It's so nice to have some color inside during the winter, isn't it?

Bonnie, do you have a west window? A west window will work fine..I wouldn't bother in a north, and an east is iffy. A Geranium would thrive in a bright east, but don't know if it'd flower. Variegated leaves need more light than green..
Last winter a piece broke off one Geranium, so I set in a 4" pot and placed in a cold room, on the bottom shelf of a south window..it rooted and bloomed all winter..
The original container has 4 different colored flowers. That too stays in a south window, but it's not all that bright..Window is obstructed by a neighboring house for one.
If possible keep artifical light on a few hours after dark. I use regular flourescent lights that hangs from the ceiling. Nothing fancy or expensive. Just an ordinary shop light?, is that what they're called, one cool white and one warm white bulbs. The entire set up cost under 20.00.
Of course, even with lights, it's not as bright as summer days, especially kept outdoors. Good luck, and Mehearty, once again, your plant is exceptional..Toni
PS..what is a tree Gardenia?

Here's a pic of them right after purchasing from the nursery last spring. I thought I was going to be able to get 3 plants to a pot, but 2 were big enough. The combinations were lovely. The red one in the front with the purple petunia isn't in the pic I posted upthread. It got huge over the winter and had to be moved to a spot where it wasn't reaching onto the breakfast table. lol

Cuttings are really easy. These things grow like weeds. I hope you get some!

Your three baskets are very attractive. What are the smaller yellow flowers with red centers in back, left pot?
I also like the little blue flowers in back right..What are they called? I've got it at the tip of my tongue but it won't pop out..LOL. I keep thinking Alyssum, sp, but blooms look too large.
Oh and in either left or front basket, there's one solo deep purple flower..what is it? How did it find its way into your basket? LOL. You have quite a collection. Come autumn, will you separate, place in individual containers? Toni
