Kale and chard in the flower beds?

Strolling through Bear Creek Gardens, I did a double take. Where I am accustomed to seeing summer flowers, I saw kale and chard.

Both are beautiful plants, but it's the first time I've seen vegetables in the flower beds.

Is it the drought? Perhaps these need less water than the flowers would.

By the look of the picture though, I'd say the wilt is setting in. Someone is going to have to water them soon.

And if someone pinches some chard, the park gardeners shouldn't be surprised. That and the kale look so tempting. To those who recognize these vegetables, that is.
