when does the spot you have.. get the sun ..

dawn and dusk sun.. are quite different than noon to 5 sun ... which involves direct sun.. and heat ...

and in your zone .... that is very important to define ...

white tissue has no chlorophyll ... read that.. no pf factor.. as in suntan lotion ...

if the plant gives off more moisture.. thru transpiration.. sweating ... than its roots can process.. in a given period.. then the white tissue will burn/brown/dessicated ... so you have to play this game of protecting it.. during its most dangerous time of day ... which is usually the heat of the day ...

I'm rather partial to Cryptomeria japonica 'Sekkan.'
The new growth is creamy white, and the foliage colors up really nicely in the Winter.
There may be some initial burning on young or establishing trees, but I have one in full sun,
morning to evening, in my back yard - and it's doing great.

Sekkan sometimes burnes, much better is the a bit more golden or yellowish Hungarian Gold syn.Barabits Gold.
Never burnes here in full sun the whole day.
But maybe it differs from location to location.

No burn on C. 'Sekkan' here, for what it's worth. If by white you mean pale yellow, you could try Picea pungens 'Gebelle's Golden Spring'. Not particularly noteworthy summer-winter, but in spring the lemon yellow new growth is so lovely that it makes up for it! See photo below.

Here is a link that might be useful: Spring foliage

I have Picea orientalis 'Early Gold' which fills the same role as your GGS. It's the earliest of the new growth fireworks and the color glows in the dark! (almost ;-) Plus it has incredible bright red cones, people have actually asked if I glued them on!

Yes! I love 'Early Gold', too! Spring is so great with new foliage like those, and those cones...I have both the GGS and the 'Early Gold' in the same area and it is my favorite spot in spring. Who needs flowers....

Chamaecyparis pisifera 'Snow' is the white or yellow foliage conifer for that matter that didn't or had minimal burning which wasn't noticed until close inspection.

12 hours of full during the hottest summer of record keeping.

Are C. p. 'Snow' and 'Snowkist' the same plant?

"Are C. p. 'Snow' and 'Snowkist' the same plant?"

No, The 'Snow' is a Chamaecyparis pisifera cultivar.

The 'Snowkist' is a Chamaecyparis obtusa 'cultivar, which is simular to 'Tonia'.

Thank you Edwin!

Two that perform perfectly well in full sun here are Chamaecyparis obtusa 'Mariesii' and Juniperus chinensis 'Kaizuka Variegata'.

FWIW, a lot of the white (not cream, not yellow) variegated Hinokis are extremely sun tolerant in my climate - 'Moonshine', 'Mastin', 'Snowblast', 'Baldwin's Variegated'. Even Ch. lawsoniana 'Barry's Silver' does well in full sun here with no tip burn. Not sure how well they would hold up in hotter summer climates.

Has anyone tried cryptomeria japonica 'Nana Albospica' in full sun?
