Useful flowerbed Staple!
Lovely flowers with blooms that keep popping up all season. Try making calendula oil or tea picking the flowers at full bloom and letting the petals dry.
I believe they were in one of a pollinator mix that I got and they are some of the most impressive flowers in my garden, will definitely be singling these out for next year. Beautiful bright yellow to orange and attractive for bees and insects.
