Hosta 'Opipara' Group

In 1991, the 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 or hybridizers.

This is one of the hosta groupings that was shifted from species to cultivar status. For more on this process ...

Species switched from species to cultivar status in 1991 include:

Hosta 'Opipara'

In 1937, Fumio Maekawa first described this plant from Japan and named it as a species, Hosta opipara. W. George Schmid later determined that it did not meet the requirements for a species and reduced it to the level of cultivar in 1991 (see above). Subsequently, The American Hosta Society registered the cultivar on behalf of Dr. Maekawa in 2002.

The plant forms a rhizomatous mound about 24 inches tall by 64 inches wide. Its foliage is medium green in color with a yellow marginal variegation. They are ovate-shaped, wavy and have above average substance. It bears medium purple flowers in August.

According to The Hostapedia by Mark Zilis (2009), "'Opipara' (or 'Bill Brincka') should be in every hosta collection...In the 1980s, however, I would not have given this plant such a glowing recommendation. Nearly every plant of 'Opipara' the United States was infected with a virus (probably Hosta Virus X). Fortunately, Bill Brincka...obtained a clean selection of this plant, which was marketed under his name..."
