About Anemone coronaria 'Mr. Fokker'

Anemone coronaria 'Mr. Fokker' · also called Mr. Fokker anemone, blue poppy anemone · flowering

Mr. Fokker is a classic single poppy anemone from the De Caen group, with rich violet-blue petals encircling a black centre ringed by dark stamens. Grown from soaked corms planted in autumn or late winter, it flowers in spring on slender stems and makes an excellent cut flower. Being a buttercup relative, it is toxic to cats and dogs.

Mature size: Around 25-35 cm (10-14 in) tall in flower, spreading 15-20 cm (6-8 in) per plant.

Watch for — Botrytis (grey mould): Grey fuzzy rot on flowers and leaves in cool, damp weather. Ventilate, remove affected growth, and harvest flowers before they fully open.

Indoor size vs how big it gets in the wild

Anemone coronaria 'Mr. Fokker' reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect around 25-35 cm (10-14 in) tall in flower, spreading 15-20 cm (6-8 in) per plant.. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.
