Besides Green Milkweed, what are other green flower natives? May garden has rainbow of colors, yet no green flowers.
Some of the more common types with green flowers are:
Ginseng (Panax quinquefolium)
Wild Sarsaparilla (Aralia nudicaulis)
Alumroot (Heuchera americana)
Jack-in-the-pulpit (Arisaema triphyllum)
Green Dragon (Arisaema dracontium)
Black Snakeroot (Sanicula canadensis)
Smooth Solomon's Seal (Polygonatum biflorum)
Ragged Fringed Orchid (Habeneria lacera)
Greenfly Orchid (Epidendrun conopseum)
Green Violet (Hybanthus concolor)
Indian Cucumber Root (Medeola virginiana)
Rattlesnake Master (Eryngium yuccifolium)
There are others, some aquatic, but many are considered noxious weeds.
These are from Texas:-
Schoenocaulon drummundi (green lily)
Funistrum cynanchoides (climbing milkweed
matelea reticulata (green milkweed vine)
What about thalictrum diocum (early meadow rue) or blue cohosh
Some of those plants I had tried in my garden or grow. Those milkweeds do not do well in my garden, and the vines are not right for city, do to growing over to neighbors yards. I mainly seeker green flowing natives that are not too big, not very weedy by roots.
