Yellow and gray are the Pantone colors for 2021. The following floral designs make beautiful use of these colors.
The featured image, from Art Floral Francais, 96 Rue Raymond Poincare, Bordeaux, France, has beautiful rhythm. This would possibly be the first quality commented on were it to be judged. The vine appears to be a bundle of fine reeds that are tied and shaped, probably with some wire within. Calla Lily stems can be easily shaped when wet. The Aspidistra leaves are also flexible and have been manipulated.
The elements have been skillfully combined. There is probably a piece of oasis hidden in the center for hydration as all the Calla Lily stems emerge from the center.
This second design has a tube like sculpture for its base or container. The interesting foliage consists of palms that have been manipulated and braided. After drying they probably were colored with gray since their natural color when dried is tan. The blooms are heliconia. Heliconia is easy to use in creative designs as it is sturdy and long lasting. This design has a creative combination of forms and textures.
The final design is a creative horizontal design. I’m not sure what the base is underneath the attached dried leaves and yellow fabric, but it has a 
pleasing form. The manipulated foliage and yellow roses create a restful design with the horizontal line. One criticism has to do with scale, or the relationship in size of one material to another. I find the tiny pieces of plant material do not relate well with the other forms–they are fussy and detract from the total.
