This cultivar is part of the "Sherborne Series" of hostas from Eric Smith. It is a second generation of Smith's famous Tardiana seedlings (TF1 × 1) × (TF1 × 4) and it was registered by the British Hosta and Hemerocallis Society on his behalf in 1988.

The dense mound grows into a small size hosta about 10 inches in height with a spread of around 22 inches. It has a slow growth rate and medium blue-green colored foliage. The leaves are slightly rippled, slightly cupped, slightly wavy and dull on top. Pale lavender flowers with light colored stripes bloom in July but seed set was unknown at the time of registration.

According to The Hostapedia by Mark Zilis (2009), "As of 1992, Peter Ruh of Ohio owned the only plant of 'Sherborne Swallow' in the United States. Since that time, a few others have obtained it, but it is still rare. The largest specimen can be found at Wade & Gatton Nurseries in Bellville, Ohio."
