Looking for "cottage look, perennial & annual platns that will do well in my zone 10a S.W. Fla. heat & humidity garden. As if that's not tough enough I have a mostly southern exposure with very little shade built in, located in front of house.& naturaly would like as easy care as possible.

Zinnia, Cassia/senna bushes, dill, parsley, lavender, Black & Blue Salvia, Bird of Paradise, Plumbago, Blanket Flower, Russian Sage, Coneflower, Coreopsis, Asiatic lily, passiflora vines .... just to name a few,

Also, succulents such as sedum, flap jack (Kalanchoe), aloe, etc. do well year round.

Good luck Dave! You are in for a "World of Heat!!" Heat like you can't imagine!
I spent 9 years recently from 2009-2018 at SW 10th Place in the Cape. And from my experiences there, it can be a struggle to grow much of anything! The sun from mid April through mid October is extremely intense! And I can't emphasize that too much.
I tried Coneflowers, they fried like sautéed onions in a pan!! Zinnias? Fry them too! Salvias ? Fried as well.

I would advise you to visit a place like Home Depot on Veterans and Skyline drive and just see what type of plant material they sell. Then plan accordingly! I found that from February through November, it was 88-94 for days on end. High humidity and searing sun! The sun was almost right overhead and very intense!! My last 3 years my front flower beds facing east became a succulent garden. I had lots of gravel and put in bromeliads and loads of other succulents and it was kind of cool! But Hurricane Irma made me realize that I needed to be closer to family.
Also, I can recommend Riverview Nursery in East Fort Myers, great advice, great plants. They will "shoot you the straight skinny!" on what you can grow there. Honestly.
Good luck!!!!

Those cottage gardens would have included tropical plants... They certainly grew enough of them inside of their conservatories...

I think you are missing the boat if you don' t embrace the wonderful plants that the rest of us drool over.

Things like banana, ginger, turmeric, brugmansia avocado...

Also, lantana, salvia microphylla "hot lips"... To name a couple that thrive here...

Also... Tithonia, and what about climbers? Lima beans, other climbing beans, moonflower, cypress vine...
