Thunbergia alata
Thunbergia alata has a vine habit, and can grow to a height of 6-8 ft (1.8-2.4 m) in tropical zones, or much less as a container plant or as an annual. It has twinning stems with heart or arrow-shaped leaves. It favours sun to partial shade. The flowers typically are warm orange with characteristic dark spot in the centre. However, different varieties can be red, orange, red-orange, white, pale yellow, or bright yellow, with or without the characteristic chocolate-purple centre which inspires the common name. Black-eyed Susans are also known for producing flowers as early as six weeks after germination.

I have noticed a lot more in parks around my area
I have some morning glory that I love and hate. It requires weekly (if not daily) control. I will take a look at how Thunbergia likes it here in CA.
I've never seen them go feral here in New England, but they seem to do very well where they're planted. I've even considered planting some around my dooryard, but I do have some concerns about them escaping.
Oh really? Interesting. Are they as aggressive as Morning Glory?
Agreed, Thunbergia. These seem to be becoming a popular replacement for morning glories in people's yards.
