Visit your local nurseries. Hostas are very popular and you can expect to find a good selection, including some fancy varieties.
Nothing beats being able to see and touch them. Talk to the staff and ask for their recommendations.
If you’re a “hosta junkie” and enjoy collecting unusual specimens, you already know that they can be very expensive. Join the American Hosta Society and connect with other hosta lovers to get their opinions on cultivars you’re interested in.
Finally, I recommend these specialty mail order nurseries for their exceptional selection, expertise and friendly service: Wayside Gardens, Glenbrook Farm, Klem’s Song Sparrow Nursery and Naylor Creek.
