Creeping Herbs

Four of our raised beds are made out of stone, and I really wanted to add some cascading herbs to it.  It took about 5 months, but the creeping rosemary is finally starting to flow over the edge.

Decorative, drought-resistant, and edible... what more could I want?

The purpose of growing plants down the stones is two-fold.  

On one hand, it reminds me of old castles and fairy tales.  I've just always loved old mossy rocks with greenery peeking through.  There's a sort of magical timeless quality to old buildings that are being slowly reclaimed by nature.

On the other hand, it is extremely practical because it frees up a lot of sun for the rest of the plants.  A typical rosemary bush would be high and wide, taking up a lot of valuable space in the raised bed.  The creeping rosemary stays fairly flat, and I've trained it to grow toward the edge.  It is growing happily under a large kale, since it is still getting plenty of sun along the side of the rock wall.  This is similar to the space-saving tactic of growing plants upward on stakes to save space.

I used a similar tactic with the sweet potato... once the plant was healthy and began producing long vines, I tossed them over the edge of the bed, trimmed the vines to 4 feet long, and used all that space it had been claiming (about 10 square feet!) for the fall crop.  The sweet potato is still happily chugging along, since it is still getting everything it needs.  I even used some of the vines as a partial shade cover for the fall crop while the seedlings needed some protection.


I definitely need to find more trailing herbs.

The rosemary was the only herb I could find at the time that would trail down the side of the beds, and I need to find a few more types.

What herbs would you recommend?
