This slow growing cultivar is a seedling of H. 'Rosedale Black Hole' which was registered by Jim Husemann of Iowa in 2009. It grows to a large size about 20 inches high by 45 inches wide with deep blue-green foliage which stays throughout the summer. The leaves are very broadly ovate, cupped and heavily corrugated. Near white flowers bloom from late June into July.

From the Field Guide to Hostas by Mark Zilis (2014), "If your hosta tastes run toward intense corrugation, a deep blue foliage color that lasts almost the entire growing season, and great slug resistance, then 'Taurus' is a must. It is part of Jim Husemann's "Signs of the Zodiac" series of hostas and is one of his best."
