Tulbaghia violacea
Nursery Pro tip: Grassy clumps, lilac blooms for months, and the garlic scent keeps deer and rabbits off.
Clumps of slim gray-green leaves topped by lavender flower umbels on tall stems from spring to frost. The foliage smells of garlic when brushed, which is why deer and rabbits leave it alone — a genuinely useful trait here.
Full sun to part shade; any drained soil. Space 12–18 in apart. Excellent as an edging plant or in pots.
Spring or fall. Hole twice the pot width, ball at grade, native soil, Root Stimulator, mulch.
Weekly through summer; it tolerates drought but blooms better with regular water.
Light spring feeding.
Cut spent flower stems at the base. Trim damaged foliage after a freeze — it's root-hardy and returns. Divide crowded clumps in spring every three or four years.
Nothing serious. The garlic smell bothers some people right next to a patio. Foliage burns in a hard freeze and regrows.
Edging a walk or a rose bed, or massed with daylilies and salvia. Its deer resistance makes it a good front-line plant where deer browse.
