various garden varieties. The second picture is a double form where the reproductive parts are replaced by spurred petals.
No interactions present.
It is difficult to give correct cultivar,they are short lived perennials that seed readily but you get various colours from seed unlike division or vegetative propagation,you could probably narrow it down if you have photo's of the leaves as they do differ between cultivar's.
Hope this help's
