I planted a collection of 36 6 ea. of 6 dif types. They all came up they all flowered but not a one reached 2'. Not Emberglow or even Lucifier. I will be in touch with the vendor. Perhaps Too much sun? Something I said. Maybe next year.

Pottsii X Paniculata
1970, Bloom. Sultry-Red interspecific hybrid from Bressingham Gardens bred by Alan Bloom, the main species in this is Pottsii, hence the flowers. H 90cm. Sets seed readily and fruiting stems sold as cut flowers in Netherlands
Planted this variety in my garden in Green Bay, Wis. Zone 4
bloomed from mid June to the end of September. The grower that I bought it from said I could leave it in the ground if I put a heavy mulch on it for winter. I dug it up the end of October and found my one plant had about 10 new corms. I was very pleased with the summer show!

Plant corms in spring after last frost date approximately 3-4” deep and 6” apart. In colder zones, mulching is necessary to ensure they are protected from winter's harsh weather. In warmer climates, keep in a somewhat shady area for hot afternoon temps.
