Agapanthus are typically grown in warmer zones, but Walters Gardens has introduced a collection of vigorous varieties that are hardy to zone 6! Agapanthus 'Galaxy Blue' was originally tested in Michigan and overwintered for the more than 7 years. They also survived the Kansas cold blast of February 2021 (temperatures reaching -16 degrees F) with no problems. They're out of this world with globular clusters that are produced on tall stems over large, rounded clumps of foliage. 4" clusters of dark blue flowers are produced and rebloom occurs if watered regularly in the summer. True blue is an especially rare flower color in the garden. Foliage resembles daylilies and turns yellow in the fall. To be safe with any "hardy tropical", apply a heavy 3-4"mulch layer for the first few years.
