Spear Thistle is fine to feed to tortoises, but the bigger spines might be a problem for smaller tortoises, so you can just snip them off with a pair of scissors.
This is a large growing thistle that forms a rosette in the first year and then shoots up and flowers in the second year. It is invasive so you should remove the flowers before they set seed.
Do not confuse with the other plant called Scotch Thistle
