Julie!!!!!
Have I got a daylily (dl) for you! Fragrant? YES! Pretty? YES! This dl takes a lickin' & keeps on tickin'. I grew it in zone 10 in coastal south Florida & it was my second best performer. It took the heat, the sun, the drought -- everything! She's a beauty. Oh & she's only 16" so perfect for your patio. And I might mention that even though she's listed as a dormant; that's relative to where it's growing & it never went dormant on me ---- maybe semi evergreen.

And my very best performer was Ming Toy. Bright, not fragrant, the first to bloom & went off & on all the way till Oct. AND it makes proliferations (baby plants on the scape). Bright pops of color & only 20" scapes so again, great for your patio.

I found both of these to increase fast so you will be giving fans to your friends.
