Greens come in sets of 6 for $6 total ($1 a piece) and can be mixed and matched. Some Kale plants are $3 because they are strong plants in 4” pots. Starting now, they each have a few leaves and will continue to grow quickly. They are currently smaller than the plants you buy at the store which is why they are $1. With most of these greens, I harvest the outer leaves every week or so and they last for months. You can also let them grow to maturity and harvest all at once.
