Annuals vs Perennials

Keep in mid that most annuals do not tolerate frost, and transplants will do better if planted into soil that has a bit of time to warm up after that cold winter. Many hardy perennials however can be planted quite early in the spring, especially if they have been kept outdoors at the nursery and are well acclimated to the weather, or if you recive them as bare root plants - meaning unpotted plants with their roots washed clean. (Perennials can also be planted in the fall with great success.)
