Ladies, It is time to let your Plant Lust come alive ! You KNOW you want to hit the garden centers. GO for it !
With NO length of ownership requirements for Pot et Fleurs (fancy name for compatible plants arranged in a container with a few cut flowers to make it even prettier) and only one month for Terrace planters and NO length of ownership for a Living Picture, you can jump in as soon or even as late as you wish. Just remember that the focus of the Pot et Fleur is on the plant material, not Great-Aunt Minerva's container.
SURELY you will have a cute pot of flowers by your door (not to exceed 24" diameter). And you can repurpose that 8 x 10 or smaller picture frame with a take-out container taped to the back and sporting a fun combination of plants. Page 20 has the rules but Google has some ideas to get you started.
Call Helen Schreiber if you have questions. Not only does she have answers, experience and examples, she has more fun ideas than you can shake a stick at.
While you are at it, pick up some things that will be in bloom in Mid-ish June so you can cut them for the arrangement in the Mason Jar class. (page19, Section E) You will have the tags so knowing their names to fill in the entry card will be easier.
