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
