Is there a small pea sized bulb that is down in the soil about two inches and connected with a single tap root. This is why pulling them up does not work. You are leaving the bulb inside the ground. If you mow these flowers then a new bulb will grow everywhere the flower lands. Also the bulbs will have babies and they will be further down as far as 6 inches and will develope a clump of babies.
It took me forever to rid my yard of these at the old house. You must dig each one and make sure you go deep and get the whole bulb system.

I had a big scare last month when I followed a link from someone I did not know. Thankfully, I have an antivirus program. The computer went crazy then shut it self down then rebooted itself and all was fine. I count myself lucky because my program was able to take care of the virus. Nothing personal, but I have developed a fear of links!
