Parzifal is one of the more compact mophead hydrangeas, noted for variable colours between pink and mauve, and best in strongly acidic conditions when a good dark blue is said to develop. Our plant is in the most acidic prepared bed, beside Enziandom, but only towards the end of the 2005 season have we seen anything bluer than muddy mauve - at last a lilac colour has developed. The rooted cutting in a pot has shown better colours. Quite often there are five sepals to a floret, but the flower heads are always fairly tidy: fringed edges of the sepals are, so far, so fine as to be un-noticeable.
