Pine Cone Mulch - an attractive border and maybe a practical way to keep dogs and cats out of your garden beds. As they breakdown, they will add nutrients to your garden too. Pine cones also look great as a decorative mulch for container gardens.
Herbs like rosemary, lemon grass & garlic chives can feature as the star attraction in large pots. Partner with a cascading plant like variegated mother of herbs, sweet potato vine or licorice vine. Should help with mosquitos as well.
