Sweet smelling and tropical hmm... Azeales are beautiful and are pretty tropical looking

A huge one I can think of for tropical loking would be pineapple lily--zone 7+
Canna doesnt smell amazing but look great
Crape myrtle is a bush with toooonnnsss of bright colorful blooms
many roses are very fragrant-- Floribunda series

Hope this gives you an idea!

Sorry, I was just looking for indoor plants that smell good and found these two but have no humidity here. I already gave up on the Sweet Olive (too big and high maintenance) but a Texas gardener suggested using a bell jar or terrarium for the Maid of Orleans Jasmine, which apparently does well here. That sounds great but they sure are expensive when you need one that is big enough for this plant which gets 1 to 2 feet tall. I mean, it's just glass and metal but costs $300!?

Thanks for the other outdoor suggestions. I have tropicanna canna, 5 crepe myrtles, and about 21 roses :) and tried azealeas before that died, but pineapple lily sounds intriging. Do they smell like pineapples because I love pineapples?

Oh yes! wow what a rose collection.

Pineapple lilies actually dont smell very nice to me, im neutral I ment rather as a foliage plant this is what it looks like, very unique
