Multi Blue is a very unique sport of the
Clematis 'The President'. Flowers are double and superb deep blue, topped with
many other shorter petals tinged in white. The flowers go through many stages creating a
different look in each stage. The center petals are small when the flowers first appear,
then expand as the guard petals expand. The photo below shows Multi Blue in its first
stage with the guard petals closed. Blooms first appear in late spring with another
showing in late summer to early fall.
