Magnolia macrophylla ssp ashei (Bigleaf Magnolia) seeds

Description

One of the last magnolias to bloom in spring, its incredibly sweet fragrant creamy white cup shaped flowers can reach 30cm across, far out sizing M. grandiflora. This hardy species looks deceptively tropical with its massive mid green leaves which have a silvery white reverse. A medium sized tree reaching 10m in height with near equal spread. Being relatively thin for their size, the delicate leaves can be damaged in strong winds so its best to seat the tree in sheltered sites. Wide spreading branches make it an ideal shade tree. Its been known to bloom at a very young age (5 years is one quote).

How to germinate Magnolia macrophyll ssp ashei seeds:

Stratified seed. Never let stratified magnolia seed dry out as this kills the embryo. Sow immediately 2 cm deep, keep moist, keep the pot outside to finish the cold stratification cycle of 120 days. Sunlight inhibits germination. Most seed will germinate in May with the remaining the following May. Newly emerging seedlings need indirect light/dappled shade at first then stronger light as they put down a larger root system. Protect from nibbling pests two years. If you baggie sow these provide room temps with no supplemental warmth as they don’t seem to tolerate this. Once you see them crack open, transplant into a pot 15 mm deep as they don’t like being in the bag at this stage and mortality can be high.
