I bought a pack of seeds from wilkos that are called butterfly annuals, it ssays they are a mixture of garden annuals to attract bees and butterflies. It does not state the names of the individual flowers but has a caution on the back that says harmful if eaten. I have pet tortoises that roam my garden during summer time, and am worried that these will cause troubl efor them. do you think they would be harmful to humans or just animals. If so I have a vacant space at my lottie can I just chuck them all down there and let them grow wild
