Beginner Gardening: New California balcony planter idea and recommendation, 1 by perig

Hi,

I have had these planters on my patio wall facing east (lots of sun) with some cacti (and a dead plant) in them but they don't look too good at this time (see the photo attached, the first floor patio wall). I've decided to take on the project to making these beautiful to give my condo a nice curb appeal and give it some colors.

I'd like to start with one planter in the photo below and start with putting something that will grow over the years and do a waterfall effect over the planter and down toward the street.

I was thinking about using White Potato Vine (Solanum Jasminoides) to do this job. My wife and I like the flowers and I read that it is heat resistant and grows pretty fast.

The planters are 34" wide, 8" wide and 9" deep. Would this work well to grow at least 3 ft down the wall over time.

I will put some other perennials or annuals behind these to make it colorful on the top. Eventually I also want to put a Bougainvillea on the first floor balcony.

What do you guys think?
