This is a (new to me) hybrid of two great species. T. recurvifolia var subsecundifolia is a personal fav with nice recurved leaves and very nice bright orange flower spikes. T. bergeri is big, vigerous and hardy. This hybrid looks to have inherited the best attributes of each parent. It has orange flower bracts and very light blue flowers.
I have some very nice clumps of this available.
A really nice dense clump of a good size
