Gardeners' Notes:

I bought this plant at Hilltop Garden Center in Perry, Ohio and have kept it indoors since February and it has been blooming nonstop since. I wasn't sure how it would do inside the house, but wanted some color and love this plant! I will put it outside this summer and bring it in again this fall and see how it does, but so far, I haven't had any problems. I leave it in a sunny, south-facing window and give it lots of water. It is definitely an annual in our zone 5 here, but love that it does well inside during cold weather!

I live in fullerton Ca (Zone 10a). I puchased this plant at lowes approx 4 months ago. It was about a 12 inches high. 4 to 6 months later its almost 6 feet high. I have it planted up againts my bird feeder. The sun hits the vine via east and west. It has climbed perfectly. The flourescent like orange flowers are awesome. This plant loves full sun and good watering. Water once a week in mild temps and twice a week in hot weather.

Buyer beware, if not taken care of properly it is known to be really evasive.

I love this vine..
