It would be nice to see one of these many corms bloom! > Hi Matt, Single corms in 5-6 inch diameter pots (deep style) planted 1 inch below the surface in our bulb mix (3b+perlite+pine bark chips or expanded shale) but the best specimen (dark form) is in a concrete block on the greenhouse floor in nondescript recycled mix. I can send you a picture pf a blooming size corm if you want. A one inch corm will grow to over 2 inches in two years and then bloom it's head off. Freddi loves this flower.
