Just as a comparator for colour, here is my BME. I am in zone 5, Ontario and this hosta gets morning sun until around 1:30. BME will keep its blue longer with less sun exposure but it naturally takes on some green during the summer...its final colour for me is a green/blue.

FWIW, I wouldn't recommend full sun in your zone 7. Even if you water it enough, it will bleach out from the sun. Sunlight does promote vigour but it also melts the blue wax off hostas under prolonged exposure.

Yes, when it comes back next year it will look better than you've ever seen it look thus far....I would recommend moving it anytime...as long as it has time to anchor itself - for roots to take hold....anywhere up to a month is how I gauge it.

Also, do the Mine alreadl flowered and it still had the long stalks.

Did it release seeds near the plant that i can look for and try to grow?

It should produce seed pods. Allow them to ripen on the stalk. If any are viable, you may have some seedlings next spring. I've never left them on so I wouldn't know. But I did leave spent flower scapes on two or three other hostas last fall and this year I have many, many green seedlings per each.

Your seedlings will probably be green...if anyone has BME seedlings, they will hopefully chime in.

I would move it and not worry with seedlings this year. Once it settles in a shadier spot, you can see if it sets seed next year. If I understand correctly, even if it produces seedlings they won't look like BME anyway...

Jo, I'm in zone 8 and most of my hostas get full sun, it's a matter of the angle of the sun, i.e. latitude and not the zone that makes the difference. I'm just north of the 49th parallel, don't know exactly where you are in Ontarario but I'll bet you closer to the 44th or 43rd parallel and the angle of the sun in your garden is steeper and therefor stronger than it is in mine in sunny Richmond, B.C. I like to grow mine in the sun as much as possible for the increased vigour, in particular the green ones...

Your seedlings will probably be green...if anyone has BME seedlings, they will hopefully chime in.

I have had a couple of BME seedlings, indeed they were all-green and from their leaf shape and texture there was no doubt of their heritage. BME is a poor seed-setter FWIW, I've had the variety for almost a decade and have had maybe a handful of pods over the years.

beany ....

replant IMMEDIATELY ...

any sun.. except the heat of the day .. call that noon to 6pm

the blue is a waxy coating... try to water with a wand.. not the leaves ... so as to avoid wearing off the wax ... same with sprinklers ... and especially during the heat of the day ...

it will NOT come true from seed ... expect about 80% greens .. of all sizes and maybe some blues ... the genetics will indicate relative sizes available back in time .... they may not all end up small ... and then of course.. you would have to think about what the bee brought to the flower ...

the pods will not ripen until late fall ... when the first opens... thats the bottom one ... the whole stalk can be harvested ...

there is quite a tutorial in the hosta library about growing seeds indoors in winter ...

Pieter, Jo is in Ontario. The person with the BME doesn't say where they are, other than zone 7.

So, what we're all trying to say, is that the amount of sun depends on where you live. I'm in zone 8 in Texas. I keep BME protected with 70% shadecloth. I'm at 32 degrees. It would be really ugly, if not fried in full sun here.

Pieter is in zone 8 on the west coast of Canada and is at about 49 degrees. He can put lots of hosta in full sun. England is the same way, they can grow in full sun as well.

So, how much sun it tolerates depends on how hot the sun is where you are.

While I am in z5a, in Northern Colorado, and can't put many hostas at all in full sun because of the strength of sunlight at 5,600' or so elevation.

Im in Arkansas.

Pieter, had you posted the OP's question, I would have realized your BC weather immediately as I am familiar with it. :-) I took a wild guess and assumed the poster was from a warmer zone 7 outside Canada....

Tlbean, thank you for clarifying your location. The short of it, in my opinion, is that you recognized that the plant was reacting from too much sun...you stated the label indicated "no direct sun" yet you decided to plant it in the sun. Simple answer - move it if you want it to look better next year. :-)

Maybe by then you might have acquired a companion or two for your Blue Mouse Ears? This forum is a dangerous place, lol! I joined two years ago...I had 67 hosta varieties...today I have 160. ;-)

==>>> yeah.. beany likes to do his own thing ...

like pear trees.. etc

LOL

btw ... back in the day ... wholesale producers .. grew hosta in mile long rows... in full blistering sun ...

first.. hosta are only shade TOLERANT ...

but ... as you have found ... they get ugly pretty fast in a lot of sun ...

double BUT .... they grow roots like all get out in sun .. so the producers did not care what they looked like by late summer ... but they had huge ugly clumps.. that could be divided down for sale ...

of course.. back then, i dont think z7 and higher.. was a big market ...
