A spring-flowering bulbous perennial with narrow three-angled leaves and delicate white flowers marked with green veining. It spreads readily and can naturalize in lawns and borders, thriving in cool, moist conditions.
Why grow it
Three-cornered garlic offers earlier spring color than many alliums, flowering when few other bulbs have emerged. It tolerates partial shade and moist soils better than Mediterranean alliums, making it useful for naturalization in cool-season gardens. The foliage provides a fine texture and the flowers attract early pollinators.
Watch out for
In mild climates or where conditions favor vigorous growth, monitor establishment to prevent excessive self-seeding in areas where you want to maintain other plantings. The bulbs may take time to reach flowering maturity when grown from seed or small divisions.
