Awesome. Great variegation, really obvious up close and still beautiful at a distance. I can't answer to full sun, particularly in your harsher climate, but it handles half-sun here perfectly: no burn, plenty of color.

It's a keeper.

Thanks Will. "Awesome" and "great variegation" sounds good to me.

I think I read somewhere on Talon's Flora Wonder Blog that he mentioned that it was a great tree and they were going to see how their M.g. 'Lightening' compared. 'Lightening' is still under observation and looks almost all white. As awesome as it looks I don't think I have a shady location for such a tree that would surely burn. I can't wait so if Will and Talon like the 'Silhouette' it must be good unless my midwest weather hinders it's performance for some reason.

I may try it in full sun and make sure it gets plenty of water until it's established. My ogon never burns so I'm thinking this one will do the same once it has enough root mass. Then again I'm not sure how much white or cream variegation it has and if that would make any difference to sun exposure compared to entirely yellow foliage.

I'll just have to quite rambling and try it out =^)

Any known growth rates on these two?

It doesn't burn at all here and mine is in full sun and super dry clay, and, I don't water it. I can't really comment like Will has because I've allowed it to grow many-multiple-leaders and it's deformed so, I really don't look at it.

I'm going to hack them for scions at a future date.

Growth rate...... I suppose so far 1/3+ meter a year. I believe I've had it in the ground for 4-years. It's about 6' tall is a guess from the 1/3 M whip when I planted it. I'm sure it'll grow quicker, later.

My plant is not a good one to be estimating for the reasons I mentioned above.
