We went to the Growing Place last weekend, and I spotted this little plant among the herbs. It was a little windy, so it was hard to get a decent shot without cranking up the ISO and losing some detail, but the colors were very nearly this vibrant.
Borage (also known as “starflower”) is an annual herb which originated in Syria, but also appears in the entire Mediterranean region. Sometimes also has pink or white flowers, but the blue ones (most common) are amazing. Blooms continuously through most of the year, even.
Amazing little plant!
