Princess vine or Curtain Ivy belongs to Vitaceae (Grapevine family). It is an evergreen perennial vine that is native to Florida, south Texas, Mexico south to Central America and Caribbean. This vine occurs in brushy areas and rainforests, and produces a dense mantle that covers other vegetation. Mature stems have swollen nodes and thin peeling bark. Long reddish aerial roots droop down from the axils. Leaves are broadly rounded or ovate, and entire. Yellow-green flowers are seen in the cymes that extend from the axils.
Anyway, these neighbors would have these vines above a pergola. They look nice with the hanging threads that have pinkish tips. The house below has a thick bushy vine on top of a pergola.
It's funny coz under this pergola, there's even a garden set and a hammock. I see the occupants having beer or snacks even when there's a slight drizzle! So yeah, the vines are really thick and leafy enough to ward off light rain. Here's a magnified view of the hanging threads with pink tips.
Not all pergolas with thick Millionaire's Vines work well though - at least in my opinion. Below is a house whose wooden pergola is close to a wall corner. The plant is very bushy and it's already dark under it. See how gloomy it appears? You couldn't even see the hanging threads.
Since I don't have a pergola, how will I plant the vine then? Well, my blank wall has a ledge near the top and I figure, that space would be enough for the vine. Hmmm. We'll see.
