I wanted to add that I have this plant growing outdoors in zone 9 and it is doing just fine. It has some die back in winter but comes back bigger and better in Spring. I had blooms for the first time last summer and they are wonderfully fragrant!
The seed pods that formed in fall did not make it thru the winter frost but, the vines seem to root nicely where ever they touch the ground so its easy to propagate.

If you like fragrant plants, you will want this vine. It is easy to grow here in full sun in Florida. The vine has very nice heart shaped dense green leaves. I have it planted in the ground in a rich acidic soil, growing up a trellis on a fence. You can also eat this plant-new, young leaves & flowers/buds can be eaten fresh (in a salad) or flowers & buds can be battered & fried. Plants flower very heavily for me in late spring/summer with clusters of small, nodding yellow flowers. The heavy, rich fragrance permeates the yard and is wonderful.

Received a 6 inch potted plant from Zone 9 Tropicals in dec 2005. Planted it next to my spa the same day it was received. Plant is approx 12 feet tall and has shot out 5 new runners. Due to the intense sun load it is in an area of part shade and high humidity. Soil is slightly alkaline but humus rich due to composted mulch. Garden bed is raised and fairly well draining. Irrigation is from a low flow 1/2 gallon emitter.

I live in Colorado and amazingly able to keep my pakalana alive for 3 years now. It has been a lot of hard work though. I was even told by the UH botanists that I would be unsuccessful because of the soil,climate and altitude. The 1st yr. was very pitiful. Since then, my plants have had flowers and it seems that flower production has increased slowly. I have 2 plants in different size pots. I noticed that my plant in the much larger pot seems so scrunny and straggly where the smaller pot is much more fuller and healthier looking.

I live at 850' alt. on the Island of Hawaii....and am struggling to grow this vine. I have read that it is best grown at sea level and think this may be the reason I am having trouble. We are 3-4deg. cooler than sea level and our nights are definitely cooler.

This vine is known as "pakalana" in Hawaii. It thrives in the heat and full sun (which is pretty strong in Hawaii), but can be grown in half-shade. It propagates well from 3" cuttings dipped in Rootone. In Hawaii, it goes dormant in late Fall or Winter, and during that time about half the leaves fall off, and it puts out 4-6" seed pods shaped sort of like Anaheim peppers.
