I'm about as plant/flower illiterate as you can get. So, no. I haven't tried them. Let me know how it goes. I'm always looking for "treats" for my little babies.
:I saw on your list that I can feed "wandering Jews." I got acres of these things in my yard! I will try to feed some tomorrow and see how it goes. Do you know if they like them as much as gazania rigens or the others?
