They do the best grown in full sun through growing season. Winter sun has no effect on them because they are dormant.

All the cultivars that you list fall within these parameters.

Yes you can grow them in filtered shade but their growth and appearance will be less then desirable.

i have globosa and ??? knight .. in almost full shade .. with my hosta ...

growth rate is severely reduced.. which is a plus in their space ....

color is somewhat muted .. as compared to full sun ...

and as time goes by .. they are less full than they should be ...

so basically .. they will live .. but they will be stunted and muted in some manner..

i would experiment with your location.. but i wouldnt spend 100 bucks on the experiment ... but that is your call ...

but hey .. if you got a spot.. what the heck ...

Thanks for the info. It is far from full shade. I gets even full sun from time to time. I will follow your advice and experiment probably. I found them at Girard Nurseries at $18 for the two year graft, so it is not that bad...
Thans again!

I have a St. Mary's Broom (also from Girards's BTW) that I started out in the same dappled shade you describe. It colored up ok but not like it is now in nearly full sun. The growth rate seems slightly better now too. So, yes, full sun is better, but it will still look good in dappled shade.
