This form is similar to a butterfly cinquain except the syllable count is not reversed in the second cinquain. The closest format I could find to this example would be a cinquain swirl which can be any number of repetitions in the pattern of 2-4-6-8-2-4-6-8. I think I'll just call it a twin cinquain in that the last 2 words of the first cinquain are repeated for the first 2 lines of the second cinquain, joining both poems. It consists of two stanzas.
ELIXIRS
(A Twin Cinquain)
Flowers
petaling out
their wares. Fantastic shapes
and colors you can't live without
Each spring,
each time that jumps
forward, I remember
how you said you would leave me with
flowers.
