Description from First Editions: Delta Blues™ Chastetree is an intermediate sized shrub that has fragrant, dark blue-purple flowers that attract butterflies and other pollinators. Dark green, fragrant leaves contrast against the colorful flowers that bloom from June to October. Delta Blues™ is deer resistant, salt tolerant, and adapts to acid or alkaline soils as long as the site is well drained. Fun fact: Delta Blues™ was the first intermediate Vitex in the market!
