Are Hostas really for shade?

I have several Hostas in my garden - all growing under the dappled shade of my Japanese Acers. One of them has a flower spike forming but it is the only one! I have looked closely at the amount of light that may be going on this particular and it is very little more than the other seven plants are receiving. In another part of the garden I have a further 4 Hostas and they haven't flowered at all this year although in full leaf. Have I read it all wrong - all the books say shade!

I have one hosta called Gold Edger which can cope with sun but most prefer dappled or full shade depending on how thick and coloured their leaves are and they usually need plenty of moisture if they do get sunshine or their leaves will crisp up.
It's a bit too late this year but I would sugegst that next spring you give each emerging hosta a generous feed of slow release fertiliser such as blood, fish and bone or pelleted chicken manure and maybe a tonic of liquid rose or tomato food for extra flowering oomph. If your hostas are new, or young, they may just be getting themselves established with good root systems before they expend energy on flowers.
Hostas' principal interest is their leaves rather than their flowers. In the vast majority of cases, leaf colour is better in shade.
Going back to flowers, many flower quite late in summer, and will probably be even later this year because of the poor weather.
Hostas can grow perfectly well in both sun and shade, although they need more moisture in sun. They make two kinds of leaf depending upon their situation, so if you move a hosta from shade into sun, the leaf-buds it made the previous year will be for shade, not sun and may result in leaf burn. It also depends on the species, but generally speaking, hostas with blue leaves dislike too much sunlight or just lose their colour and turn green in sun.
As already stated, hostas are principally grown for foliage, and some people cut off the flower spikes since some varieties will pretty much die back once flowered. (these tend to be the big ones) whilst other varieties will have a second growth spurt after flowering and make a new flush of leaves. (these tend to be the fast growing ones) although there are exceptions to these rules.
Flowers or not, sun or shade, they are worth growing however you like enjoy!
I have hostas alll over the garden. Id say theyd like a mulch at their feet rather than worrying about sun or shade.
A few weeks ago, Monty Don said it was a fallacy that hostas need shade. I agreed with him, as mine are in full sun all day, and flower well every year. He said full sun is fine as long as they get lots of water. Mine are in pots, standing in saucers of water.
What do people have planted next to their Hostas? I want to plant some in a shaded border.

I have hostas planted on a shady bank amongst ferns, pulmonarias, dicentra alba, foxgloves and ajuga.
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
I also have mine among ferns and pulmonaria plus mecanopsis poppy, poor mans gunnera, candleabra primulas, astillbe etc
i have some in the shade and they are very happy and some in tubs in full sun all day..they are the same breed and are also very happy..thou water everyday...
the ones in the sun have more flowers than those in the shade.. and their leaf colour is not so bright.. so you can get the best out of them in both positions.
in th shade they are next to astibillies, ferns, helebores, woodruff, cowslips, primrose and jacob ladder and pulmonaires..
my five hostas are all under the shade of great big conifers, and doing fantastically well, they are in fact the only thing in my garden I can actually feel smug about!!!
