A few weeks ago I bought a goldfish plant (columnea x banksii) - I think it was probably at Home Depot - and while repotting it this little branch broke off, so I stuck it in a tiny bottle of water. That's what I usually do when something like this happens, even if it's not the preferred method of propagation for a particular plant according to the gardening authorities. The worst that could happen is that I have a pretty mini-bouquet for a while, but if I get lucky, the cutting roots, as this one is doing (the roots - all 2 of them so far - are still very small and not visible in this photo, in which the plant appears larger than in real life). The added bonus - totally unexpected! - is the 3 blossoms! It's obvious where the plant gets its name. No sign of buds or blossoms on the parent plant, but it looks nice in its new pot, which will go well with the blossoms when they appear.
But in some ways, I'm most excited by this little plant that's growing out of the bottom of a head of celery. Here it is after about a week floating in water,
So I guess my point is that it's fun to see things grow, fun to make something from what we'd normally throw in the garbage or at best the compost. And if you have kids or grandkids, or any kids, around, both you and they can have the pleasure of watching something grow and of learning together.
