Allium Sphaerocephalon This unique & understated allium with unusual oval-shaped, violet-green flower heads perches atop tall, slender stems. Like all Alliums, this bulb is easy to grow on well-drained soil, & will pretty much take care of itself. Sphaerocephalon must be planted in bold groups to appreciate it at its best. Grow them in dense clumps among other perennials – they associate particularly well with swaying grasses. The perfect choice for sunny borders & gravel gardens.
