Hosta Robert Frost will form a large mound of 20"-24" in height, with a spread of up to 50", at maturity. It is breathtaking in spring when the frosty blue-green leaves are bordered by a nice yellow margin. By late summer the mound is green with a streaky white margins. This large Hosta would be a highlight in any shade garden, easy to grow, erect habit,  forming a nice large clump. Can be a little slow to get going but it will get there. This Hosta has pale lavender, almost white, flowers held on tall scapes of up to 36" tall, from July to August. It can be sun tolerant and fairly slug resistant.
