I used a lot of Baptisa foliage in these bouquets. I also used Sweet Annie (Artemesia annua) in a few of them. Other than that it is still the same flowers just combined in different ways. Here is an example of the Baptisa foliage. It is almost as blue as eucalyptus, and certainly easier to grow but of course does not have that great scent.
I am getting more comfortable using the silver artemesia foliage. It looks really nice with blues and pinks, it might even work with yellow but I have not tried that. Artemesias all have a sharp, herby scent. I find it invigorating but some people might not like it.
I really liked this simple bouquet of white lisianthus and statice with orange zinnias. I keep meaning to do more like this but orange has generally been in short supply this year. Too much cantelope color and not enough orange.
