Hi Gastil, Since I know you are careful to look at the seeds and photograph them, perhaps this key will help you sort out what you have. The seeds of all three are orange. Both Chasmanthe aethiopica and C. bicolor have the reputation of being weedy/legacy plants depending on how you look at it. From Crocosmia and Chasmanthe by Goldblatt, Manning, Dunlop Key: Stem curved at the base of the inclined to horizontal spike and flowers carried on the upper side of the axis, usually in one rank; slender part of the perianth tube spirally twisted; seeds fleshy when first exposed, later becoming dry and wrinkled, the inside of the capsule reddish to purple = Chasmanthe aethiopica versus Stem and spike erect, often branched and flowers carried in two ranks; slender part of the perianth tube not spirally twisted; seeds dry, shiny, with a hard seed coat, the inside of the capsule straw-colored If the latter, either: Tepals orange to scarlet, the lower more or less spreading, except the lower median; capsule warty and with a nipple-like apex; the upper tepal arising 1/8-1/4 inch (3-7 mm) beyond the lower tepals = Chasmanthe floribunda Upper and lower medial tepals orange to scarlet but the lower laterals green, all directed forward; capsule smooth, rounded at the apex; all the tepals arising at about the same level = Chasmanthe bicolor Mary Sue
