This Thunbergia alata, commonly known as Black-eyed Susan vine, was a gift, way back in May, from a gardening friend. There are two colors planted in the container, which occupies a sunny corner of my deck. I tied string from the plant stakes in the pot to the downspout so it would have something to climb.
And climb it did. Right up to the wires. This vine does not need to be fertilized, but when it gets this big, it requires copious daily watering because the soil in the container can no longer hold sufficient moisture to support all that foliage. Apparently it also likes to be grown in moist soil when planted in the ground.
I like the darker blooms on the second vine. The hummingbirds enjoyed this column of flowers all summer, too.
This plant is native to Madagascar, Africa and Asia, so it’s perennial in Zone 10 or warmer, which Rhode Island is most definitely not. It will be tossed when its season ends, after adding considerable color and interest to the deck for several months.
