Tulbaghia fragrans (now widely treated as Tulbaghia simmleri) is a small bulbous perennial from South Africa, grown for its showy, dome-shaped umbels of soft pink to mauve flowers that carry a genuine sweet fragrance, unusual for the genus. The strappy, grey-green leaves form a neat clump and release a mild garlic-like scent when bruised, giving rise to the common name sweet or fragrant society garlic.
In India it performs best as a container or border plant in cooler northern plains during winter, in hill stations, and in the milder months elsewhere. It is easy to grow, multiplies readily from its bulbs and tolerates a fair amount of neglect once established, making it a rewarding low-maintenance ornamental for fragrance gardens.

Growing tips
<p>In the north Indian plains, grow in pots and enjoy its main flush through the cool winter and spring months; shift containers to bright, sheltered spots and protect from frost. In hill stations it can stay outdoors year-round.</p><p>During hot, humid monsoon and peak summer, move pots to a brighter, airy, rain-sheltered position and cut back on watering to prevent bulb rot. Lift and divide overcrowded clumps after flowering to maintain vigour and increase your stock.</p>
