Kathy, some of the easiest outdoor plants for me are passionflower (Passiflora incarnata), dianthus, brugmansias, cannas, Red Bay trees, cypripedium parviflorum ( shhhhh ), gardenias, closed gentian, manfreda, the ubiquitous yucca, weigila, edible fig, etc. along with so many others with our mild climate in the Fall/Winter.
The house plants I find easiest to grow is one which I ordered just y'day: Murraya paniculata, cereus, string-of-pearls (sorry, don't know the botanical name), pothos,
That's all I can think of at the moment. Thanks for asking this and thanks to all who might read it. Lee

I have a few passionflowers but I have to haul them in and out. Wish I could grow figs here but we do have currants, tons of blueberries, peaches and red raspberries so I'm content. I grow clivias, amaryllis (really hippeastrums), epiphyllums (orchid cacti) and rhipsalises, succulents and cacti, and many hoyas indoors as well as chinese and brazilian irises and more. I just got a camellia seedling and hope I don't kill it! This place just teams with plants all winter!
I just looked up Murraya paniculata and it was a bush. How large do they get indoors?

Boo, the one I had grew up to about 3 feet and was luxuriant in its foliage. Of course, the great thrill was the scent of the blossoms: just like orange flowers. A common name is Orange Jessamine but I detect nothing of jasmine, just oranges.
I had no problems with the roots or the leaves. Even after a good pruning, it sprang back no worse for the wear. Too, I just used Miracle Grow potting mix for it but gave it excellent drainage.
I think I just used something like Miracle-Grow on it at 1/4-1/2 tsp. every couple weeks.
I feel sure I'd still have it had I not acted as if I knew so much and put it in full sun without ANY acclimation at all. Weren't I just real bright?
Anyway, I'd consider getting one and I think you'll enjoy it as the flowers for most of the time are present and since you have a greenhouse, it would be perfect for you.
Take care, Lee
P.S. I haven't tried the one which smells and tastes like curry as I don't like curry.

MMMmmmmm. I do. I used to have a curry plant but it didn't taste like curry. I don't have a greenhouse and I shy away from large plants since they have to be moved a lot here with my bad back but since I adore the smell of orange flowers I will keep it on the wishlist!! Thanks for telling me more about it!

Kevin, what zone are you in? I never post on this thread because all of those plants you mention are not houseplants here. My only houseplants are orchids!

LOL. Carol, I'm in zone 7-a. But I just say zone 7 as it simplifies things for me.
No, I don't suppose they would be house plants there, you lucky lady. But for us they are.
We have a little snow each yr. with bitterly cold northern winds and freezes. I'd
be like a kid in a chocolate store to be able to grow some of the things outside which we must grow inside.
However, I am able to grow gardenias outside esp. August Beauty and Radicans. To me, the South wouldn't be the South without Gardenias and tuberoses which I can grow. LOL, my mother used to say tuberoses reminded her of a funeral home.
I'll look through one of my books and see if you are able to grow some of the ones listed. If so, you and I simply must swap houses for a couple seasons.
I find that on some occasions I can buy a plant which says it is a zone 8 grower but I can push it up a point with extra care from the cold wind. It just takes a little planning. Sometimes it works and at oher times it doesn't. Lee.
