Mark Zilis has been working with hostas for over thirty years as an avid grower, hybridizer and nursery owner. In 2009, he published the most comprehensive book on the genus to date titled, The Hostapedia. In this massive publication, he makes personal observations and comments on around 7,000 thousand hosta species and cultivars.

Taking this amount of information and making sense of it quickly becomes a dizzying problem. So, we at PGC thought it might be helpful to sift through the pages and pull out many of the most highly praised, outstanding hostas according to Mark Zilis' opinion. We call each plant a" Mark Zilis All-Star".

Mark also occasionally found some problems with certain hostas which warranted a negative review. We have called these losers a "Mark Zilis NO-Star".

Of course, Mr PGC agrees with each designation (good or bad) and recommends that all of you serious Hostaphiles buy a copy of The Hostapedia today!!

Mark Zilis'Comments from The Hostapedia

H. No Star:
H. 'Lunar Eclipse' "When I found the first sport out of 'August Moon' in the early 1980s, I was quite excited...Then, after naming, registering and marketing the plant for a few years, it became evident that, with maturity, the margins developed the dreaded "drawstring" effect. In fact, that term was introduced to "hostadom" to describe what was happening to 'Lunar Eclipse'."
H. 'Moon Shadow' "...develop spots that can occupy anywhere from a small portion to a majority of the leaf surface...the spots mar the beauty of 'Moon Shadow', making its widespread usage debatable."
H. 'Mostly Ghostly' "...emerges whitish in the spring, then slowly turns green. Like the others in this class, it has interest only to the ardent hosta collector and is not a good garden plant."
H. 'Nutty Husband' "...develops drawstring effect. By midsummer, the white margin usually tears and turns brown. Another one to avoid."
H. 'Panda Bear' "Like other plants infected with Hosta Virus X, 'Panda Bear' has a kind of exotic beauty. Still, it should not be propagated or cultivated to avoid bringing a source of this virus into your garden."
H. 'Pooh Bear' "I cannot recommend this cultivar for landscaping purposes...it does not have a fast growth rate. Even worse is the fact that the gold leaf center develops a significant amount of spring desiccation burn. There are better choices."
H. 'Retread' "...undergoes numerous color changes throughout the growing season...makes a poor garden plant and should be treated as a curiosity."
H. 'Sea Yellow Sunrise' "I consider this one of Mildred Seaver's "lesser" introductions."
H. 'Snow Cap' "...difficult to grow; margins often tear (not draw stringing); smaller than 'Northern Halo'; not recommended."
H. 'Something Good' "...has also been sold as 'Sumthing Good' and 'Sum Thing Good'...it's not, or at least all of the plants I've seen are not...good. The variegation is difficult to discern, even from a close distance and is not worth the ample amount of space that it needs in the garden."
H. 'Spotted Janet' , "...same as 'Janet' except for dark green dots and splotches due to an infection with Hosta Virus X..."
H. 'Walden' "This virus-infected cultivar can still be found in some gardens, though few collectors will admit having it. To some it is beautiful, though I think quite the opposite...If you somehow have a specimen, destroy it."
H. 'Watercolours'
aka 'Kiwi Watercolours'
"...another cultivar named as a result of its infection with Hosta Virus X...Like all other infected cultivars, it should not be grown as it poses a potential risk to any nursery or hosta collection."
H. 'White Shoulders' "Unfortunately, it has been a failure as a garden plant because the margins disappear with a few years of planting."
H. 'Winning Edge' "Unfortunately, it often drawstrings, tearing along the margin. For that reason, I do not recommend growing this cultivar. If you do own it, cutting off the first flush of foliage will produce a second set of leaves that should not exhibit the drawstring problem."
