Chives are perennials. If you want seeds, let the flowers set them. Some people find they self-seed quite readily. If you don't want the seeds, eat the flowers! Either way, it won't hurt the plant. Chives will often die right back to nothing in winter, but they will resurrect come spring.

Thanks DaisyD. You must be looking over the fence. My chives were doing really poorly in winter and I thought I might need to plant more. Next thing I turn around and they are standing tall, looking much bushier, with the aforementioned flowerheads. They do appear to like the spring. The spring onions I planted on seed tape aren't doing so well, though. Very slow to grow.

Hi all
Does anyone you know have red flowering chives
cheers
