got this plant from a friend - multiplies like crazy in the sunny, sandy site I chose. Don't know best time to dig bulbs and replant, but it has tolerated several experiments! Beautiful old stock, very hardy, lots of huge flowers on tall stalks. Even the foliage alone is nice.

Excerpt from Plant Delights catalog: There are many plants parading around under the moniker H. x johnsonii. Most of the plants actually seem to be this old hybrid between H. aulicum and H. x johnsonii. H. 'Ackermanii' is an extremely hardy and vigorous cultivar. The wide, glossy green leaves are topped in late April and May with 20" spikes ending in star-shaped, red flowers with a white star central pattern.

Mine was rescued from a construction site in Pensacola, FL but has adapted well to Raleigh, NC. Very easy to grow and multiplies nicely.
