There are so many plants included in the forums..it would be difficult for me to pick a favorite..brugmansias..morning glories ..tropicals..plumeria...eppi's...or perhaps my favorite wouldn't be a plant forum...perhaps it's where something is grown...up north...the Deep South...Floridia ...or maybe how it is grown....it could be the container forum...each a new learning experience..full of folks to instruct...assist...and even sending plants...cuttings..and starts to get you going....growing...,too much fun with each of them ...for me to pick just one....sorry....
