Allium Serendipity (Pw)

Compact, upright clump of glossy blue-green, thick leaves which emit a slight smell of onion when crushed. This makes a striking accent plant. Flowers are suitable for fresh cut arrangements. Stunning, round heads of purple-violet flowers. Full sun in a well drained site. Will tolerate some afternoon shade.  Does not want to be wet.  Zone 4-8.
