Advice on heuchera please

Hello Pennyfarthing :)

I have 8 different Heuchera, some are planted in sun and some in shade and they all do equally well.
I have the very dark purple ones in full sun positions and they don't fade, i have Marmalade in full sun and that one doesn't fade either.
The one that does though is Key Lime Pie and ..... it only fades if it's starved of water, i've neglected one of my KLPies and that's what happened.
I have green Spice in full sun, i don't have Tiramisu but i would place them where you want them and if they show signs of unhappiness move them.

Great plants PennyF....Tiramisu was featured at 'chelsea flower show' this year'....Louise is right....i also have them planted in shade and sun.....:>)

Pennyfarthing - I am growing 'Tiramisu' but it is showing signs of scorch on the leaves - I think part shade might be better for this one

I bought Tiramisu from the Gardeners world show the other week.

Where it is planted it gets sun with dappled shade throughout the day.

Thank you all very much for these replies. I shall plant them in partial shade with tiramisu in the shadiest spot.
