There is an image of this cultivar on the Hosta Library. From the photo on the HL website, it appears to be a small size hosta with green leaves and a wide creamy yellow medial (center) variegation. Later in the summer, it becomes an all-green leaf. 'Mieke' is noted as an early emerging hosta and may be susceptible to late spring frosts. This non-registered cultivar was originated by Dirk Dupré of Belgium.
