| Don't know about cultivars but the ones in my clients garden are the deep red ones.
Echium is definitely more of a problem but Dodonea is still a pain

I don't notice the Dodonaea reseeding to be nearly as much a problem here in the SF Bay Area. Yes, it does occasionally reseed, but nothing like Pittosporum undulatum, Eriobotrya japonica, Ligustrum lucidum, Acacia melanoxylon or Hedera canariensis. In my opinion, these are the worst introduced ornamental plant culprits in an irrigated landscape here in the East Bay. The ones that have berries that birds like to eat are typically the worst spreaders for me in my garden, especially in areas under trees or power lines. I suppose I should also add Quercus agrifolia and Black Walnuts, but the squirrels and blue jays do more to spread these around than the others.
Same here near Monterey. Our neighbors have a few of these and while I do find seedlings, they're never as extensive as Echium fastuosum is (that seeds a LOT more than Dodonea does). I still wouldn't find them a pest though even if they seeded a lot here, unless you insist on a well manicured garden. I let them reach knee height and then they're easy to pull for me. Even when I see Dodonaea growing wild outside of town it's always in disturbed soils.
