Yup, what tj said. Then it needs to come back the next year still looking different. Much wider/thinner edges, different colors, different shape, etc.

if you think you have one.. lets see a pic ...

its rare that it is the same variegation ... but only a matter of a little bit wider or thinner ... more like a solid in a variegated plant [which is usually a reversion back to what it came from] ... or a var. out of a solid plant ... [sporting forward to something new]

hosta are rather unstable ... and do weird things all the time ... and we as mavens.. notice it ...

but a single leaf is an anomaly ... and usually wont return.. what we are looking for is a whole plant ... a whole piece of crown ... that we could detach ... and grow into a new plant ...

I'm sure it had one sport/reversion, which we've divided off and replanted in its own spot. I'm not sure what else it might have going on in it.

Here it is (minus its sport) ... it's big:

What is the name of the hosta you started with? Your first pic shows one with two different color shades. Undulata??? That is one confused plant. Got something familiar to throw in there for size? Those leaves could be 2" or 8" long from here.

Babka, I think that's different sun exposures in the first pic. BlueberryBundtcake, you'll get better garden pictures on a hazy day or early or late when there's no direct sun. I keep trying to catch special sun effects on camera, mainly to no avail.

Okay, I finally got out with a camera at a time when the whole hosta is in the same light. I don't know what variety it is. My mum got it as division from a neighbor's hosta something like 25 years ago.

I'm not sure why houzz is rotating my photos now ... but here it is:

It look likes an undulata. They do that all season. I don't think that's a sport.

I think you have a sport in that last photo from the first set - the all-green one with one funky leaf. In all the years I've grown mine, I haven't had the luck to run across an all-green sport.

I agree that it is Undulata but it is a very unstable one displaying 'Univittata' traits (the all-white centre) as well throughout the plant (the leaf in your hand).

The "misting" appearance is a transitional phase in subsequent flushes of growth which next year will appear normal. As Kathy stated, it will do that all season. I have three or four different Undulata cultivars including a Univittata among them. An old plant but never a dull moment with this one! :-). It looks beautiful in the absence of slug holes or other imperfections imo.

The rotation might have come from your iPhone/iPad? (just an assumption) I use both devices to take my photos and it took me a few tries until I got the hang of it...you could edit your photo rotation and resubmit that clump photo. It is the nicest one I've seen ever!

The green in that one was the sport, and then it's going back to the variegated pattern or something funky like that. It got removed from the main plant. It used to be in that divot next to the daffodil. So now it's a green hosta with a variegated leaf as opposed to green leaves on a variegated hosta.

Thanks! It's one of several around the yard. It's actually not the biggest; that honor belongs to the one next to the house, since it doesn't have to cope with deer nibbling at it. (Deer would be the reason the green division is missing leaves.) Just can't seem to spritz them with anti-deer concoction fast enough when they first emerge and after rain; we've been doing better at making them distasteful to deer this year, though.

That is called "viridescent". Undulata does that.
