The allium flower, a striking edible bloom from the same botanical family as onions, garlic, leeks, and chives, is both visually captivating and culinary-friendly. Tasting notes reveal a delicate onion or garlic-like flavor.milder than the bulbs or stems.with a slightly sweet, grassy undertone and a gentle pungency that doesn.t overwhelm the palate. The petals can be sprinkled over salads, roasted vegetables, or savory pastries, lending both color and a light aromatic sharpness.
