I know it's late, but I love our Russian Olive Tree.
(It's late because the blooms, and the aroma, are long gone. But I loved it while they endured.)
Why you ask. Because of the leaf color; blue/gray. And the aroma while it's in bloom; unbelievably sweet scented. Impossible to ignore.
In our area it's basically a weed tree, but we really enjoy it.
And this is for you especially, Genie, our Moongarden is doing well and being utilized;Three of the roses are blooming in this photo; Iceberg, Constance Spry and Blanc de Coubert.
I've even roasted some marshmallows in there lately.
And work related: I've recently been switched to mornings (per my request), so I'm now required to move myself out of bed at 4:30AM if I want to fit in my exercise routine pre-work. (And yes, it's best to do it BEFORE work.) So, I've been re-scheduling my day; again.
