[ Rhododendron 'Aglo' | Posted on September 19, 2020 ]

I haven't been able to trace the exact parentage of this cultivar, but one source describes it as 'A hybrid rhododendron with close ties to the PJM group'. It is even sold as 'PJM Aglo'. Another source simply says it's "an inter-species hybrid'. From the Missouri Botanical Garden page for it, "PJM Group is a series of rhododendron hybrids that resulted from crosses between R. carolinianum and R. dauricum var. sempervirens."

[ Dahlia 'Mary Jo' | Posted on September 10, 2020 ]

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.

[ Dahlia 'Enchantress (III)' | Posted on August 5, 2020 ]

The Dahlia World master list has ten entries under the name 'Enchantress'. This garden.org entry gives size/form/color data for that matches one of these, the one attributed to Hacek (a large red formal decorative cultivar, number III on the Dahlia World list), but most of the photos seem to be of a semi-cactus, dark blend cultivar. In the Dahlia World list, there's a similar entry (number VIII) that is attributed to Swan Island, and Dahlia Addict's entry under 'Enchantress' seems to be of the same or a similar cultivar. There is also an orange water lily form (Dahlia World number VI for 'Enchantress, attributed to Miller). This explains the different types of flower form and the different colors specified in this single garden.org entry. They describe three different cultivars!!!

This mixed database entry for 'Enchantress' is very confusing. Honestly, I don't know the best way to handle the situation short of creating different entries for the different cultivars of the same name. Somebody, help!
