Ornamental Onion 'Ambassador', Ornamental Garlic 'Ambassador', Spring Bulbs, Spring Flowers
Award-winner Allium ‘Ambassador’ is one of the tallest and most architectural onions with its large globe-shaped inflorescence, 8 in. across (20 cm), densely packed with hundreds of small, star-shaped purple flowers. Blooming for up to 5 weeks from late spring to early summer, this spectacular bulbous perennial enjoys one of the longest blooming seasons. It remains ornamental in the garden well into summer.
Hundreds of Allium species exist, but only a few have made a name for themselves as garden plants. The ornamental onions distinguish themselves by their remarkable diversity in color, inflorescence, and flowering height. Many species bloom in early summer – just after the spring-flowering period and just before the exuberant full bloom of summer. Certain small species are just perfect for a rock garden, and several lend themselves to naturalizing. All species can be used in the border.
