of new and different hostas has exploded
over recent decades.
One of the early hosta pioneers,
Paul Aden author of
Hosta Book, stated that in 1988, "...at least 600 hosta cultivars have been formally
In a 2010 presentation, Mark Zilis,
hybridizer, author of
on hostas and former owner of Q&Z Nursery commented
are now over 8,000 identified types of hostas and around
5,000 hosta cultivars registered
with The American Hosta Society."
That is an increase of nearly 10
fold in that 22 year period. Of these new
cultivars, many, many differ from others in only one
minor trait making it difficult to
differentiate between certain sets of cultivars. In fact, unless you are willing to make
a lifetime study of hostas like Mark Zilis, most of
us will be unable to tell hundreds of hosta varieties
Helper Collection - In our ongoing
efforts to help people select hostas for their
gardens, we have
photographed many, many hostas on our journeys around the
So far, we have included information
on 8,425 species and named cultivars both registered and
non-registered. We also include pictures of
that we have taken in public and private
gardens, nurseries and leaf shows over the years.

as we have sifted through the huge amount of
information in The Hostapedia, we have made
note of the best and the worst hostas in the opinion
Mark Zilis. These are listed in our
Mark Zilis NO-Star listings.
Hosta Numbers: As we have sifted through
tons and tons of information about hosta cultivars,
it has become apparent that some of the numbers
thrown around are a bit deceptive. For instance,
Mark Zilis in his wonderful publication
The Hostapedia (2009)
discusses around 7,000 named hostas that he has personally observed
over 30 years or more. However, this does not mean
that you can go to a nursery or online shop and buy
that many different hostas.
Actually, many, many of the named plants
exist only in the garden of the originator or a few
collectors and will never be introduced into the
marketplace. Others are under long term evaluation
and some are noted as "not existing" anymore.
Hosta cultivars for which we have
information are listed by alphabetical order.
