what to put in railing boxes?

[kvet]

Hi:

Would you all be kind enough to suggest some plant ideas for my 3 railing boxes?

Original setup: one with early bloom wildflowers, another had alpine strawberries, and third had nasturtiums. The wildflowers were pretty but died quickly because I spread the entire seed packet over a 2sqft area. The bushy nasturtiums were mutants, twisted, ugly, and I did not like their taste. The strawberries began nicely but now they look terrible, browning leaves, the berries are very fragrant but "meh" in the flavor department. I am over them, just not worth the trouble.

The location gets full sun but subject to heavy wind. In inches, two boxes are 36*12*10, other is 24*12*10 (width, height, depth). I'm zone 10a, coastal southern california.

Ideal plant: something shorter, edible, and perennial with pretty blooms Bonus points if the blooms have an aroma! Am I greedy? Yes.

I read up on herbs, most seem to be annual, or, maybe grow tall so wind will be problematic? I tried growing some outdoors years ago and they became a haven for all sorts of bugs that made me switch to growing herbs indoors.

Perennial chamomile? Maybe some sort of tuber plant or berry bush or ?? Hmmmm.

Thanks for any ideas
