Here is an idea. Use clover for a bunch of something green and fresh and lovely to fill your vase.
It has so many positive connotations and it lasts for such a long time.Every day it will be there to greet you rather than a bunch of expensive flower that last a day or two an then wilt and fade.
Clover just stays fresh an green and perky, and for me, has a sense of luxuriousness.
A field of clover always evokes such a truly delightful image.
And the best part of all of this idea is that clover is FREE to us all to pick!
Go and pick some clover.
And celebrate the sense of joy that it brings.
