I've been researching to buy plants for my rooftop. We live in the Caribbean, so the plants will receive at least 6 hours of direct sun. The heat is also unbearable.
With that said, I saw an ad where the owner is selling several
Areca Palms for USD $10 each. Here's a picture in the ad:
The palms are 3-4ft high, and they're in 1.5-gallon pots.
Will this outgrow their pot?
Also, how large will these grow?
Will this plant survive in hot, humid weather with lots of sun? It's been raining a lot lately, but you can really feel the heat and humidity when it stops and there's full sun at noon. When it's not raining, the temperature mid-afternoon, on a sunny day, can reach over 90°F.
Finally, assuming I decide to buy a few of them, is there anything I would need to look for in the plant to make sure it's healthy?
