Growing and Maintenance Tips

Allium 'Serendipity' is a low maintenance, well behaved perennial that will attract pollinators. It is easy to grow in average, dry to medium moisture, well-drained soils in full sun to part shade. It performs best in full sun but will tolerate some light afternoon shade. It tolerates a wide range of soils including sandy soils but will not grow well in heavy clay. Although ‘Serendipity’ is a true bulb on a stout rhizome, it forms a clump which can be lifted and divided in either spring or fall.
