PlantFiles: Bengal Clock Vine, Blue Sky Vine
Thunbergia grandiflora 'Variegata'

My purple flowering vine seems to be a Bengal Clock vine, aka Blue Sky vine. - thunbergia grandiflors, however mine has a plain green leaf, not a variegated leaf. The leaves are around 5" long, pointed at the bottom and heart shaped at the top, same shape as in the photos. It 20' tall. Is this a Bengal Clock vine with plain leaves? It is growing in Seabrook, TX.

I bought my Sky Vine at Lowes here in Sumter, S.C. It grew to at least 20 feet the first year , covering a built on trellis across the front porch . It was beautiful ! Cars would stop to look at it . I've not seen another one here . I went back to Lowes to see if they could order another one but they couldn't seem to get any more in . I'm still trying to root some pieces for family members but so far , I've only had one piece to root . Mine died back in the Winter but came back in the Spring . It gets the afternoon sun and only shade in the morning . I think it's a great vine , very showy and easy to grow , as long as you maintain the new shoots that appear every day !

I don't grow this, yet...but have watched it on a trellis here for the past five years. It seems to be quite hardy in zone 8A. It is growing in full sun with no shade and seems to bloom from mid June until hard frost.

We purchased this plant about 2 weeks ago. It had several pale blue flowers at the time. It has started growing and the newest blooms are decidedly darker blue that the ones that opened last week. I wonder if they fade to light blue or if the trend will continue.
