Welcome to the boards from Texas.
Here's a free orchid paper pieced quilt block that you might try for the groom. I'm still looking for a sprig of thyme. Maybe you could find some fabric that had thyme in it & fussy cut around it & applique it on a block for the bride. Maybe even do the same thing if you don't want to paper piece. I'm sure orchid fabric would not be to hard to find.
Here's a fabric with orchids in it:
