this looks like a great mothers day/grandparent gift/ teacher gift idea. Lots of options with flowerpots, buckets, etc to put it in and with the types of flowers or stems to use and filling in the pail.
Could also be used in a spelling center.Lego-out the words. Lego learning games - exploring Lego and play dough. This is a great activity for sensory play, imaginative play, letter recognition and sight words.
