Vigorous growing, sturdy shrub that can grow up to 5' and possibly becoming wider. Saucer-shaped corymbs are covered with irregularly placed red to purple ray-flowers. The sepals are large, slightly dentate. Flowering time is from August to September. Suitable as a pot plant and for outdoor cultivation as well. It must be fed aluminum sulfate to turn the flowers blue, even when the plant is grown in acid soil. Mowe means "seagull." Dirr reports that this is the lacecap version of 'Ami Pasquier' type and color and could possibly be the same plant as 'Geoffrey Chadbund'.
