Tree Mallow - invasive?

[ArtichokeAardvark]

A quick question that Google isn't proving much help with- if I plant a lavatera / tree mallow alongside my gravel drive, am I going to find baby mallows popping up everywhere for ever more? I know common mallow is a nightmare, but does the same apply to its much bigger cousin?

My other thought was hibiscus but ideally I'd like something semi evergreen as it's to screen the road from view! Needs to be happy in full sun and fairly drought tolerant. Heght-wise anything up to 2metres is ok.

I had one which didn't produce any offspring. But iirc you're meant to prune them hard in spring and I didn't think they were 'semi evergreen' so not sure they'd be an ideal screening plant. (Maybe it depends on variety and location though)

I am no gardening expert but I had a 4 year old lavatera in a raised planter in the corner of my garden. We had to dismantle the planter and therefore move it. Unfortunately it didn't survive the move and I planted a new one on the same spot later, in the last month or so have noticed new sprouts from some of the old lavatera roots that we missed. I'm leaving it to do its thing now, but hoping it doesn't invade the neighbours with their artificial grass and hatred of all living things.

Thank you both!
