There is much confusion regarding marketing of 'Black Mulberry' in the nursery trade here in the USA. True black mulberry - Morus nigra - is largely limited to being grown in areas with a Mediterranean climate... it does not fare at all well in the eastern US, as fungal diseases favored by our hot humid summers do it in. Even Dr. Bullard had long ago despaired of growing M. nigra here in the east. But there are many nurseries which advertise 'Black Mulberry' varieties, which are merely black/purple-fruited selections of Morus alba - including 'Persian Black', mentioned in your article.

There are numerous 'everbearing' mulberry varieties which are naturally-occurring hybrids of our native Red mulberry, Morus rubra, and the introduced Morus alba. These hybrids' fruits - while they may never approximate the depth of flavor of a true Morus nigra - have a much deeper flavor profile and better sweet/tart balance than those of M. alba, and are more productive than M. rubra. 'Illinois Everbearing', 'Collier', 'Lawson Dawson', and one of Dr. Bullard's own favorites, 'Silk Hope' are shining examples of these tasty M.rubraXalba hybrids.

There are a number of NAFEX members who have in-hand, and are continuing to propagate, many of Dr. Bullard's selections, including the rescued antebellum mulberry varieties, 'Hicks Everbearing' and 'Stubbs', which were mainstays on southern farmsteads as food sources for poultry and pigs. But, with regard to NAFEX taking conservatorship of Dr. Bullard's collection, I think that is not to have been a possibility.
