I have 3+ of these in the front garden of a home I just purchased. I'm trying to figure out what they are as I am considering removing them. Is this a plant that I should just remove and throw away or do these hold any value? My main concern is safety. Each "leaf" (as you can tell, I know nothing about plants) has one large and extremely sharp spike on the end. Sharp enough that it went through the sole of my shoe and threw my jeans on numerous occasions. These are right at eye level for kids and and worried about someone getting seriously hurt.
Anyway, short version...can anyone identify this?
