It is often the case that no two seedlings will be exactly the same. We believe this phenomena to be one of the more interesting facets of propagating trees from seed - botanic surprises, uniqueness and variation in leaf colour and habit in tree seedlings are welcomed as strong diversity in the garden is a natural and interesting botanic condition in its own right. It should be understood that many vegetatively propagated, widespread 'named variants' originated from open pollinated seedlings. It is a misperception to assume that 'named variants' have a corner on the beautiful and unique. A tree doesn't need a vanity tag to be both beautiful and unique.
Diversity is a natural condition and a worthy botanic end in itself.
