The dianthus in the background are part of an annual mix called Merlot. They somehow overwintered this past winter, setting up this picture

Stunning! Thank you for sharing.

Beautiful! I've had mine for several yrs. It survived the Camp Fire in 2018 and has come back beautifully. As for your dianthus... they really are perennials. The plant suppliers sell them as annuals because in some colder zones they don't come back. I've had some of them live for many yrs.

@Beth Hana I know that in warm climates that dianthus are a perennial. i was surprised to see them over winter in the 5b/6a zone that i am in
