Other Names:  Flowering Onion

Description:

A compact ornamental onion producing a clump of grass-like narrow foliage; lavender-purple florets appear in globular clusters on stalks above the foliage in summer; mildly fragrant; impressive when massed in groupings; great as a long lasting cut flower

Ornamental Features

Peek-A-Boo Ornamental Onion has masses of beautiful balls of lightly-scented lavender flowers with purple overtones at the ends of the stems from mid to late summer, which emerge from distinctive white flower buds, and which are most effective when planted in groupings. The flowers are excellent for cutting. Its grassy leaves remain green in color throughout the season.

Landscape Attributes

Peek-A-Boo Ornamental Onion is an open herbaceous perennial with tall flower stalks held atop a low mound of foliage. Its relatively coarse texture can be used to stand it apart from other garden plants with finer foliage.

This is a relatively low maintenance plant, and should only be pruned after flowering to avoid removing any of the current season's flowers. It is a good choice for attracting butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Peek-A-Boo Ornamental Onion is recommended for the following landscape applications;

• Mass Planting
• Border Edging
• General Garden Use
• Container Planting

Planting & Growing

Peek-A-Boo Ornamental Onion will grow to be only 6 inches tall at maturity extending to 12 inches tall with the flowers, with a spread of 15 inches. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 5 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen! As this plant tends to go dormant in summer, it is best interplanted with late-season bloomers to hide the dying foliage.

This plant should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments. This particular variety is an interspecific hybrid. It can be propagated by multiplication of the underground bulbs; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Peek-A-Boo Ornamental Onion is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a mass of flowers against which the larger thriller plants stand out. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
