-Ready late March- A most genteel selection done by Maedyth Martin a while ago. She brought one for display at the APS National Show in Portland OR, around 2014 or so and 'Silver Bell' was my favorite. Delighted, she kindly gave me a piece and finally we have a few to share. Grows in most well drained garden soils; this one needs extra drainage. Full sun is fine in higher elevation and/or cooler regions, otherwise needs a place without afternoon heat.
