    Confusion between two dahlias named 'Mary Jo'.
    The one described here matches the one listed by Dahlia Addict and offered by Swan Island (a miniature orange/pink or light blend semi-cactus), and the photos here agree with this description. The problem is that the date of introduction (given here as 1976) and the hybridizer/introducer (Abellara) seem to belong to a different 'Mary Jo' dahlia. Piecing together year of introduction from Swan Island, who sells the Min SC form, 1968, and the information in Dahlia World's master list, I deduce that the 'Mary Jo' in the garden.org database is 'Mary Jo(I)' in Dahlia World's list, and was introduced in 1968 by Franz. The other one, 'Mary Jo (II)' is a large, orange SC introduced in 1978 by Abellara. I didn't want to offer a data change for year of introduction and name of the introducer without explaining the basis for this change.
