if you have june ... the leaf should be an exact duplicate.. in every aspect but coloration .......

i find it nearly impossible to tell any solid blue from any other ... i could list a couple dozen it might be ...

but i can tell June from across the yard ... so if the leaves match.. bingo ...

ken

PS: something for scale on a leaf might help also ... next time

May is also a duplicate other than coloration. I have May, June and Halcyon next to each other since I like the leaf shape and form.

Halcyon has 49 registered sports.

I do not think that's Halcyon. My Hal does not have any folding to the leaves as this one does.

I bet that is Blue Cadet. I don't think it is Halcyon.

Thanks, all. I don't think it is 'Halcyon.' It's close enough but for color, that one can understand how a labeling mistake could have been made.

I did look up every single 'Halcyon' sport before posting and this plant isn't like any of the photos I saw.

The leaves are glaucus silvery-white underneath.

Its leaves are the same shape with more substance, just a bit smaller than 'June's' and, same shape and substance but a bit larger than the leaves on my juvenile 'Touch of Class'.

And there is the pesky issue that my plant has 9 (at most 10) vein pairs whereas 'Halcyon' and the others have 11.

I have several 'Blue Cadets.' That's a good guess, as the leaf and overall plant size is similar to mature 'Blue Cadet.' But this plant is much more upright (like 'Halcyon'), and the leaves have greater substance, the pointy tips and distinctive V-shape, whereas my Cadets grow lower and mounded, leaves are more rounded and most tend to turn down slightly, the Cadet petioles are not as stiff, and the Cadets also are more blue.

I don't recall that it has beautiful blooms like 'Blue Cadet.' I will note the bloom time, and take pictures of buds and blossoms and revive this thread. Maybe that info will give us another hint.

Nameless or not, it's an attractive healthy plant so for now I will just enjoy it as h. 'Anonymous.'

i have never been impressed with vein counting meaning much of anything ... except that you are in some mysterious ballpark ....

i mean really ... differing number of veins based on how mature it is.. that just doesnt help ...

All my Halcyons have uniform color. Those leaves appear, at least on my monitor, to have a slightly darker edge. Also those appear to be slightly cupped, and the Halcyons I've seen don't have that. It looks too small for a 6yr. old too. Hmmmmmmmmmm.

Halcyon is the bluest here. It flattens out and the leafs seem larger and rounder than in your picture.

I don't think it's Blue Cadet either. BC is almost a dark blue-green color.

Ya know, the form kinda reminds me of Gold Drop.... maybe try going down that path to see if it has any siblings/cousins.

It sorta reminds me of Blue Wedgwood, except for that darker edge...

-Babka

Ken, thanks for your comments on vein count. I have another misnamed unknown (and it's "a big green one" so I have little chance of identifying it with any degree of certainty). I won't rule out candidates based solely on vein counts any longer.

Thanks, everyone for your helpful suggestions.

'Gold Drop' form is close (but it's not gold or chartreuse, and the leaves are not quite as long or narrow). 'Blue Wedgwood' is a very close match, except that mine has no rippling whatsoever on the margins and it lacks blueness, comparatively.

It most resembles 'Tardiflora.' So it must be somehow related to the 'Taridiana series' (of which, one is 'Halcyon').

Here is a leaf with 'Touch of Class.'

The typical leaf on my TOC and on the mystery hosta measure the same, 6" long by 4" wide. The clump in the top picture in my original post is about 14.5" high and 35" in diameter (according to a cloth tape measure from my sewing basket that I tossed over it. It's really squishy out there so I couldn't measure carefully without wading in and crushing the soil). Ordinarily, this mystery hosta is dull, not shiny, but it's still raining lightly as I took the picture.
