This white mulberry cultivar is distinctive in its columnar manner of growth. Thus 'Pyramidalis' has become a much-used solitary tree. The crown is open and the branches grow more or less straight upwards. Sometimes a few branches bend outwards as they grow. It can eventually attain a width of approx. 3.5 m. The irregularly shaped leaves can grow to a length of approx. 15 cm. Young leaves are lobed, older leaves often smooth-edged. The leaves are a glossy light green and rough to the touch. This exclusively dioecious tree bears unremarkable female flowers. The small fruits resemble raspberries and are edible. The white fruits are slightly sweet to the taste. This is a tree for a sunny, warm, sheltered site. Saplings are sensitive to frost. Likes chalky soils and grows in poor soil.
