gladiolus byzantinus "cruentus" not the lesser gladiolus communis
Searching for the beautiful heirloom Mediterranean corm-forming Gladiolus Byzantinus "cruentes" summer blooming with glowing magenta flowers w/dense irislike clumps of foliage that support its heavily laden flower spikes.
All my searches for this have turned up the inferior Gladiolus Byzantinus communis which is a small, runtier form and a pale color.
