Thank you, Dollythehun. This is the kind of answer I'm hoping for. I hope to get some more responses like this, and I'm sure some of them will work for me.
Not to be a wet blanket, but this really should have been "This one is always in bloom for me."
Here is the original poster's request: "If you have plants that have shorter bloom times but that reliably bloom more than once a year, please share their names--especially if they're beautiful and fragrant!"
