Hi Maggiepie! Welcome! Don't apologise - we aim to please. You need to know about Don Rawson's lists - there is a list for every hosta connected topic you can think of, including sun tolerant cultivars! Here's the link.

Here is a link that might be useful: sun tolerant hostas

Thanks for the link, Jan.
The only one of my new hosta/s on Don's list is Plantaginea.
I could be in a bit of bother.

Well, hi there Maggiepie....

Plantaginea is the species plant, and it can take a good bit of sun. Your Ginsu Knife is a fragrant hosta as well, and it has plantaginea genes in it, so consider it a sun tolerant until proven otherwise.

The amount of sun hosta can take depends on your growing zone quite a bit. What zone for you? I'm in zone 9a, where no way can even sun tolerant hosta take the full sun all day long, morning sun is the best here.

If you are talking afternoon sun late in the day in a hotter zone, it takes a lot of water to keep the hosta going.....and they might fry on the leaves, but the roots will grow big (as long as you keep them watered).

My hosta (over 300) are kept in containers, and I can fine tune the amount of sun they get by moving them around as the sun pattern changes, and as the intensity increases. I also use large market umbrellas to provide shade, and I have container shrubs that I move to make a shade screen for late in the afternoon.

Plantaginea, Ginsu Knife, and Bridal Falls are three on your list that I grow. In my zone, they get mostly morning light, and get shade but good light conditions the rest of the day.

exposure to sun.. is dependent on how far south you are .. where are you...

needless to say.. they all benefit to being out of the sun during the heat of the day ... they simply can not pump enough water.. to keep those big floppy leaves looking nice ... so try to avoid noon to 5 ....

regardless.. none will die in sun.. they will just get uglier... faster ...
unless you dont water them.. then they will die...

heat doenst help either ...

where are you

moccasinlanding ,thanks for the advice.
The place where I was planning on putting these hostas are pretty much in sun until around 2.30-3pm.
Can't even imagine moving 300 pots of hostas around to get out of the sun, sounds like a huge amount of work.

Ken, I am in North Eastern New Brunswick, Canada.
Zone4b.
People around here have hostas growing in full sun that don't seem to suffer too much but I have no idea what they are but suspect they are varieties that have been around for donkey's years.

Oh my, 4B Canada?
Well, I know it gets hot up there too, but how long could the summer last if one of your winters is ready to begin.

In my climate, it is an endless summer. Or else it is almost summer. Spring lasted longer this year, almost 6 weeks. Now we have summer. Which will go on until November, and then the hosta will begin going dormant.

You have a good place to test out "full sun." Good luck with it.

Summer does not last very long at all.
Bit of a change to an Oz summer, not sure which is worse, 8 months of summer or 8 months of winter.

Will plant most of them in the sun and hope for the best.
Cross fingers we get lots of rain.
Thanks, moc.

Yeah, I can appreciate too much of anything is not the best.
My DH gardened up in MA for his whole life. He was used to things taking full sun there. He was not concerned either about not air conditioning his house, because the hot season lasted such a brief time. Now he is here in Alabama full time, and I cringe when I see him locating seedlings from his veggie garden in full sun. Like the artichokes he planted for me. He starts the seedlings and then I help him locate a good spot.

Presently he is on a mission to remove camphor tree roots and old azalea roots from a long wide flower bed near the street. He had to stop because the soil was too wet down a foot or so, for him to use the SawzAll (reciprocating saw) to cut the huge roots.(It rained two days ago) But once that bed is clear, I am looking forward to adding hosta IN THE GROUND to that spot. Beneath the palm trees. Near the banana trees. He said it was a lot cooler at that end of the bed than the end near the street with day lilies, which tends to be drier as well as more exposed to the western sun.

I suppose every small bit of land has microclimates that welcome a diverse group of plants.

Your hub sounds like he has to learn the reverse of what I had to learn when I came to Canada.
Camphor, banana and palms reminds me of Oz too.
Camphor Laurel? trees are the absolute worst things to get rid of.
My hub has a sawzall too, will have to remember that word.
He's waiting to use it on the roots of a ninebark I had to kill recently.
Am sure life will be much easier for you once you can get some of your treasures into the ground.
The good thing with pots is you can arrange them every which way until you find the combinations you like most for planting.
