About three years ago I planted these chives and every year since I’ve been either harvesting these pink chive buds & adding them to salads (they taste like an onion) or I’ve let them get pollinated, then wait a couple weeks, and harvested their tiny black seeds in order to grow more chives. I’ve read that they’ve been used throughout history as a means to naturally prevent bugs from eating different plants in the garden. In practice, however, I haven’t seem chives be very effective combating the aphids.
