the 1st and 3rd are Clerodendrum thompsoniae (Bleeding Heart Vine),

the third one is 'Delectum' cultivar.

The last photo is Snakeweed, Stachytarpheta species. It's a really bad weed and very invasive. Even small plants start flowering and shedding seed continuously. Very difficult to get rid of. But butterflies love them.

Nice photos, Matt!

That last bloom is more often called Blue Porterweed where I live. I guess it keeps it from being confused with the several other plants with "snake" in the name. It does indeed reseed itself easily, but I've found that to be a bonus.

Thanks for sending the link, I love Florida plant guide! That's my go to. I thought it was different the way the flowers grew up like that.. I am on the hunt for a bleeding heart vine tho for sure :)

i can't see the detail of the flowers on the 2nd one.

it's possible it's Justicia chrysostephana 'Orange Flame'

i assume you are in Canada?

here's the quebec site with many tropicals.
