This hosta was once thought to be a species (H. fortunei) but was changed to cultivar status (H. 'Fortunei') by Schmid in 1991. There are many, many cultivars which also had their names changed from, for example, H. fortunei 'Gigantea' to H. 'Fortunei Gigantea' at that time. These plants were often used as parent plants for others which means that H. 'Fortunei' would be in the Genetic Background of all of these cultivars. There are also many hostas called 'Fortunei'-Type.

This is a group of medium size, intensely blue-green hostas which were developed by English hybridizer, Eric Smith in the 1960s. They were the result of an unusual cross when a normally early season blooming H. sieboldiana 'Elegans' produced flowers in late summer. That allowed Smith to cross it with late season blooming H. 'Tardiflora'. Recently, what was then considered the species, H. sieboldiana has been changed to cultivar status as H. 'Sieboldiana'.

In our database, H. 'Tardiflora', 'Sieboldiana' and 'Elegans' have been included in the Genetic Background of 159 hostas which are either part of the original Tardiana Group or are noted as being a "Tardiana-Type" plant. This indicates that the person giving this designation felt that one of the original Tardianas was in a plant's genetic background.

This is another plant that was once considered a species (H. tokudama) but was changed to cultivar status (H. 'Tokudama') by Schmid in 1991. There are many cultivars which had their names changed from, for example, H. tokudama 'Aureonebulosa' to H. 'Tokudama Aureonebulosa'. These hostas were often used as parent plants for others which means that H. 'Tokudama' would be in the Genetic Background of all of these plants too.
