Deciding which plants to place together can be made easier if one has a specific theme in mind from the beginning. For some, the decision is little more than a random act of planting. For others, the specifics of the garden's location and conditions dictate what should be planted and where. And for others, every plant is chosen and situated according so a grand plan--the theme. Presented here are some themes (some purely asthetic, others purely practical) that may inspire you. If you have a favorite that we have not included, please mail it to me (keith@ahners.com).
