I sowed several varieties of Magnolia from 2003/06 and was overwhelmed with the results. I had great success with Wilsonii, Sieboldii, Watsonii, Campbellii and Sprengeri. So many seedlings came up that I had to find homes for them. Eventually I found a home for 37 Sieboldii with someone I knew with a 10 acre garden. We thought that an avenue would look rather spectacular, but, given the time it takes to flowering, probably neither of us will see it !
