Max, My experience is that T. tricolor wants to climb up, unlike T. majus that just clambers on other plants. This habit is more suitable for hanging down. You can probably stick some non-bamboo stakes in your window box/polyethylene bag and have your tricolor climb on them. The species isn't particularly vigorous and doesn't climb too far. It may outgrow the stakes in a few years when the tubers get really big.
