I have a small Northfork Pine in a pot that I got around Christmas. Can they survive the Oklahoma year round weather, and if so - when is the best time to move them outside?
Unfortunately, the Norfolk Pie is not hardy here in our zone. They are only hardy to zones 10-11, being native to a small island in the South Pacific. In their native habitat they can reach heights of 200'. Wow!
They have an interesting history, and I'm attaching information regarding this lovely houseplant.
Here is a link that might be useful: Araucaria heterophylla or Norfolk Pine
They survive outside in Southern California. I saw a very large one--about 2 feet in diameter--in Pasadena when I lived there. It never occured to me at the time that it would be grown as a houseplant, but my daughter started with one a foot tall and now it is over 5 feet. What do people do with them when they outgrow the living room ceiling?
Dorothy, lol, I don't know - build another story onto their house? These pines that really aren't pines at all, can be hardy in South Florida and warmer zones of California and grow very, very tall.
Many of our tropical houseplants grow much larger in their native landscapes. Split-leaf philodendrons, for example, can grow 70' up a tree in its native habitat. They are big houseplants, for sure, but get even bigger where they are allowed to do their own thing, which is climb.
Classy - view your Norfolk Island Pine as a houseplant. You can put it outside in late spring and summer but bring it back inside before winter. Cold weather will kill it.
Dorothy - I've seen huge ones in southern Florida - so big and dramatic, I didn't recognize them as Norfolk Island Pines. Southern CA and southern FL = no freeze zones.
I bet they are a sight to see! I've been to Florida on several occasions, but before I became interested in anything other than ornamental Begonias (all the types other than the bedding varieties).
They are very pretty houseplants IMHO!
Dorothy, I suppose they either have to give them to someone with a taller ceiling height indoors---or top them, although I think that would spoil their shape.
Classy they are an easy houseplant because I had one for years until it took up too much space. I kill all houseplants except succulents. They not only get tall but they get wide and that was my problem with the plant.
