Hosta 'Tardiflora' Group

Note: The plant label above is incorrectly written as if this hosta were still considered a species and not a cultivar, its current status.

H. 'Tardiflora' has thick, slug resistant green foliage on a medium size (12 inches high) plant. Its lavender flowers appear late in the season and may not have time to mature and set seed before frost in many northern gardens.

This plant has been the mother plant of many sports and seedlings. The famous blue-green H. 'Tardiana' Group which was developed by English hybridizer Eric Smith is a cross between H. 'Tardiflora' x Hosta sieboldiana 'Elegans.'

It may have been sold in the past as Mackwoods No. 17.

In 1991, the then most comprehensive book about hostas, The Genus Hosta by W. George Schmid, was published. It was the first intensively researched book about the entire genus which, until that time, suffered from a lot of misinformation and name confusion. As the result of his research, Schmid determined that several of the plants previously treated as separate, naturally occurring, species were, in fact, cultivated varieties, i.e. cultivars, created by nurseries and hybridizers or of unknown origin.

This hosta is one which was historically considered a natural species but was changed to a cultivar by Schmid.
