I'm sure I'm not the only driver on East Harbor Road (south Whidbey Island) who has pulled over to check out the succulents and self-seeding flowers growing atop a series of old stone piers. For several hundred feet along this scenic road, passersby are treated to the site of these handsome old piers sprouting weird and wonderful plantings, obviously thriving on their own out there, without supplemental water. There's something self-sufficiently modern yet curiously hobbit-like about the display... have you ever seen lustier hens-and-chicks (Sempervivum tectorum)?
A snapdragon managed to seed itself amid the hens-and-chicks colonizing top and sides of the pier.
A single willowy foxglove gives a Dr. Seuss-like feel to the scene
I love how the plants creep down the sides of the pier and cluster around the wood railing
