Herb Spiral Thriving

This Spring I built an herb spiral at my parent's house in Delaware.

This is just after planting the herbs:

This is a few weeks later:

I got some Parrot's Feather, Water Hyacynth, and water-cultured Peppermint for the pond.

And here it is today, looking great!

I followed the plans here:

Soon I plan to build a smaller version with smaller bricks.  I also want to see how cheaply I can build this in a community garden in Philly with discarded cinder blocks.
