I am not sure this is good for the envirnoment. sometimes wildflowers can be weeds. you should check it out first.

if a seed is not local to the area you want to plant it, it is best not to plant it unless its in a private garden and you can control its spread.

flowers are all very well but often when things go wild, if they are more vibrant than some of hte local plants, they will take over and the local plants could die out.

iwth teh case of vines, which is something i am currenlty having to deal with, they can take over a tree adn kill it.

its best to leave nature look after itself unless you know what you are doing.
