That one will remain mostly shrub like, it was formerly(IMO, appropriatly) known as a dipladenia, they are all considered mandevilla now...
Dips have small thicker shiny leaves, they overwinter just fine inside!
Mandes have larger thin quilted leaves and scramble up and around anything! Including you if you fell asleep too near it!
They are generally much less reliable indoors!
The only pest bug that feeds on em is mealy bugs, that I've seen, thrips and whiteflies can get in Mandes too but rarely on the slick leaves of dips...
I enjoy the rare bug that comes in with my tropicals. Except the pill bugs! They can just roly poly right the hell on!
Seriously, they can seriously damage soft fleshy plants like cacti and some tropicals, not your plant so much... Keep pots outta the grass and they are much less of a problem!
