This subspecies of Magnolia kobus is perhaps the hardiest of all magnolias. Just as beautiful as M. kobus but the tree form is quite a bit larger and has a spreading sinuous form (12 m tall and twice as wide in 50 years). White slightly fragrant white blooms open mid April. Flowers and seed from this subspecies are some what smaller than M. kobus,var kobus but the seed is significantly smaller but this doesn't hinder germination one little bit. Never lime magnolias (EVER!). Use acidic fertilizers if you need to. All magnolias love bark mulch.
