Magnolia grandiflora seeds (Southern Magnolia seeds)

Description

This lovely eastern North American native evergreen magnolia species with large glossy leaves with a russet fuzz on the underside. Huge 20cm single creamy white sweetly fragrant flowers(reminiscent of sweet lemonade) perfume the air in June to frost. The petals are so thick and so firm they probably can withstand their seasonal hurricanes. Fast growing in the right spot. It is not uncommon for mature trees to reach 20 meters tall with half the spread. Of course there are smaller cultivars but here we offer the species in all its glory.

How to germinate Magnolia grandiflora seeds:

Stratifying seed. Never let 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 for too long and mortality can be high.
