Dietes bicolor, perhaps. Here is a link that might be useful: dietes bicolor

i was told.. and call it.. a woodland poppy ... which i believe is a common name for what carol said they ramble around my hosta bed ... in a non-irritating way ... ken

Wow, you people have such an experience with it. I love that plant and while it does spread around a bit it is nowhere close to being the pest you describe! This year was first year I actually dug out few pieces to give away after having it for 3 years. It is not hard to remove where I do not want them either. I also have variegated lyshimachia Alexander which also behaves. Again my garden is informal so I really do not care if they do not form clump or migrate a little, have not noticed them migrating more than couple of feet from original placement. Maybe it is because I grow them in the shade but have not had any problems from them. I have bed of lysimachias, tiger and asiatic lilies,aconitums, macleya cordata, corydalis lutea which reseeds like crazy but very happy and blooms all summer and dwarf yellow and variegated bamboo. Those ones do try to get into walking path grass but not invasive enough due to being not fully cold hardy here. Out of all of the only bamboo is kind of hard to dig up.

Nkt, removing flower stalks opposed to allowing them to remain is mostly done to save berries/seeds for germination. I too read removing the stalk soon after flowers fade, strengthens the following years buds. If you want to sow seeds from your Clivia, use the brightest, mosts mature, red berries. I had an old 10 gallon aquarium filled w/a couple inches of soil. Odds andd ends were rooted inside. One year, I left the flower stalk on until berries reddened. I didn't want to toss them, so I removed each seed, and inserted in the aquarium soil. Months passed, 'can't recall how many,' and baby Clivia seedings grew. When each stood about 7", with 4 or more leaves, I gave them to friends. Give seeds a try....Toni
