Agapanthus ‘Xera’s Cobalt’

Our own seed strain taken from the very darkest blue flowers in the Agapanthus kingdom. Prolific blooming, long lived, cold hardy perennials that require rich, well drained soil with regular summer water. Full sun to very light shade. Blooms of the deepest cobalt to black rise on average to 30″ tall for 4-6 weeks in mid-summer. Completely deciduous in winter. Wonderful in the middle/back of a border and a natural with ornamental grasses and Kniphofias. Add a handful of lime to the hole at planting time and put the Agapanthus right on top of it. The parents of this strain are all naturally very hardy and do not emerge until all threat of frost has past. Hummingbird plant.
