Centranthus, or Jupiter’s beard, is a great perennial, but be prepared for its rather vigorous self-sowing. It is very tolerant of most conditions and needs little water.

The leaves are strap-like with flowering stems that vary from eighteen inches to five feet, depending on the variety.
Tulbaghia, or society garlic, is an evergreen perennial with narrow green or green and white variegated leaves. Clusters of small lavender flowers top stems that are one to two feet tall. Provide regular water. Because of the garlicky odor of the leaves, deer tend to leave it alone.
