MAGNOLIA sieboldii 'Colossus'
|
Parentage: Kehr
Description: A polypoloid form of M. sieboldii created, selected, named and registered by Augie Kehr in June 1997. This selection is thought to be a hexaploid. It arose by doubling the chromosomes of seed from the cross of M. 'Genesis' (a tetraploid sieboldii) by a diploid
sieboldii. The flowers are large, often 5 to 6 inches in diameter
with 10 to 17 heavy-textured tepals, and very fragrant. The tree flowers profusely. The leaves are up to a foot in length and 6 inches wide. The original tree was 8 to 10 feet high by 10 feet wide at 7 years of age.
