In late February for the past 10 years or so, I've purchased a hanging basket from Lowe's, filled with Creeping Charlie (Glechoma hederacea) and Wandering Jew (Tradescantia zebrina) to place in a tall patio planter. I spend about $13, an inexpensive way to have a great spot of color on my patio for a few months, until the hot weather does it in, usually by June 15. When I first place it in the planter, I cut off the wires and the hook for hanging, and then just watch it grow. This year my plant has continued to thrive well past its expected expiration date, and is now sweeping the patio floor. I've trimmed it a couple of times just to keep it off the floor, but otherwise, I do nothing to it but water.
I think the reason it is doing so well is that this year I started watering it twice a day beginning in mid-June. It's amazing to me that the root system can support all this foliage. The size of this arrangement is deceptive. The pot it's in is an 8" pot with a depth of 6". That pot is sitting inside a large ceramic planter pot, and the planted pot is resting on another pot turned upside down.
Each year when I see the arrangement moving toward its demise, I take off a few cuttings and place them in a vase in the house. Those cuttings can last for years in the vase if I choose to let them go.
