. There are a ton of very beautiful flowering plants that will grow like demons in PA and more north of the Southern tier that we cannot ever hope to grow here. I have a friend who lives in PA, she is a plant friend of 25 years at least...her property is simply a dream in the growing season. All this stuff I have never even seen and do not know what it is, both flowering and foliage. All I know is out heat zone is way too high for it so it is never sold here. I wanted desperately to grow HOSTAS 15 or so years ago, I could just see beds of many gorgeous varieties...I bought some mail order and made trades for others and guess what? It was way too hot here in summer and they all just melted.
People always want what they cannot have, or cannot EASILY have. People who live outside the warmer climates want tropical plants, people who live in the oppressive heat and humidity of the Spring-Summer-Fall and even some days in winter that is Florida would be tickled pink to be able to grow cooler growing plants. It was 81 degrees here on Monday, almost that high yesterday...the humidity was so high it was condensing on the windows and sidewalks. The low Monday night was 67. We have a cool front for 2 days, then the warm weather comes back for 2 days, then another cool front. We have yet to freeze, we had a light frost a couple weeks ago but that's it. 20's are always a possibility, but it all depends on if a cold front with enough oomph makes it here or not. For the last 3 winters, none have. We have 90's as daytime highs sometimes in February in this part of FL, because we are 50 miles inland from each coast and get no sea breeze. South Florida is actually cooler than we are here in the warm months, but they stay warmer than we do in the cooler months. Its a trade off. If you looked at red Ti plants, Strelitzia, bananas, palms, gingers and crotons growing in just about every condo complex and apartment house in town, and Hibiscus varieties and Thaumatophyllum selloum (tree philodendron) in practically every yard in town, you would become blind to it. It wouldn't be new to you anymore. I greatly admire people who make little tropical plant havens inside their homes. But its not done by accident. It takes nurture and paying attention to the needs of each individual plant. Watering practices can differ from plant to plant even within the same Genus (Alocasia come to mind). Humidity needs can also vary greatly. And so can light needs. The people who are most successful realize that there is no blanket policy that can be applied to every plant. Which is why people in the aroid community especially have thrown out the 'water the the top inch or so of the medium feels dry' axiom. And started addressing the planting substrate, not the amount or frequency of water.
