An excellent choice for novice gardeners, Salvia guaranitica ‘Black & Blue’ (anise sage) offers deep blue flowers throughout the intense heat of summer. Hummingbirds love this low maintenance plant that blooms from June to frost. The dark purple flowers contrast nicely against the black stems and light green foliage.
In the landscape, anise sage pairs well with other summer blooming perennials such as Rudbeckia (black-eyed susan), Solidago (goldenrod) or Perovskia atriplicifolia (Russian sage).
Where hardy, anise sage can spread to over 5 feet wide in only 4 years. The perennial can easily be controlled through division of the shallow roots. When planted in full sun anise sage stays around 3 feet tall, but when planted in too much shade the plant tends to elongate towards the sun and can grow over 5 feet tall. Cut back the plant to encourage dense grow that will not fall.
Anise sage is hardy to from zones 7 to 11, and can be used as an annual in northern climates.
