    Features

    I'm more LOW MAINTENANCE than your OTHER relationships.

    Watch in spring as incredibly dark stems emerge from the ground. Olive green leaves have silver veins. Star-shaped, periwinkle blue flowers appear atop of the wide, mounding, shrub-like habit.

    • I planted two of these, one late autumn 2017, and one mid-summer 2018. The planted-2017 grew, had foliage, didn't bloom though until spring of 2019. The planted-2018 bloomed in 2019. Both have done really well, but the planted-2018 plant is stronger, healthier, and its blooms were far more numerous, the foliage fuller. The difference may be that the healthier one is planted in a close to full sun place, whereas the other is planted in an almost part shade spot. The plant is extraordinary, regardless.
