Perennials are mulched in late fall to protect roots and rosettes from winter injury. Many herbs grown in containers can be brought inside to provide a fresh supply of herbs during the winter months. Some herbs are harvested, bunched, and dried for later use. A cool well-ventilated dark area is good for drying. Herbs are useful for a multitude of projects from making herb vinegars to sachets and scented pillows.
Culinary herbs can also be ornamental.
Some provide color like the purple-leaf basils or texture, like curly parsley. Many herbs have delicate flowers which can be pleasing up close, while others such as chives are quite showy. A border of herbs can make the vegetable planting more pleasant to work in. Mixed with annuals in a window box, herbs become a delightful retreat from household chores. One attractive way to display herbs is the knot garden, in which the various colors and textures of herbs are used to create the appearance of cords looping over and under each other.
