I love hostas, but they have a reputation for being difficult, not least because of their attractiveness to slugs and snails. They are commonly thought to do best in moist partial shade, but this shockingly dry year has been a surprise. As Chris Beardshaw points out, there are several that do well in dry shade, the sieboldiana types in particular. Although many of mine in direct sunshine for most of the day have scorched this year, there are also several that have done surprisingly well in quite dry and sunny conditions.
Hostas were originally named in honour of the Austrian botanist Nichloas Host, but in 1817 the name Funkia was used by a German botanist in honour of botanist Heinrich Funk. The name Funkia remained in use for some time and there are a number of horticultural texts written over this period which refer to Funkias. In 1905 Hosta was reinstated as the genus name by the International Botanical Congress.
I quite like the name Funkia. It makes me think of the plants secretly having a good time after I have gone to bed.
