If you want them to be used in any sort of feed capacity, I would say that you would need more than a few plants. I recently started a hundred or so seedlings in order to make a feed hedge for the future. They are easy to grow from seed and are very hardy. They grow pretty fast and don't need any attention. The flowers are nice and attract many pollinators in the early spring.
Maybe start with a few plants and then use them to produce seeds for later propagation if they work out for you and you needs.
