While the amsonia excitement of
the past week was largely luck, I think I've completely choreographed the performance-to-be of this extraordinary variegated holly.
Colorful evergreen leaves? Check! Contrasting red berries? Check! But those are just the obvious opening steps in our little show here...
...the mere baseline of competence for this performance: It's a
variegated holly, Samantha. If this plant isn't going to lead off with showy foliage and berries, what the heck is it doing on stage in the first place?
Rest assured, Ladies and Gentlemen, this luscious American holly and I have cooked up quite a
pas de deux for your viewing pleasure. And foliage and berries are, indeed, just our opening steps, our casually exciting warm-ups for the death-defying moves to come. (Which display of staggering talent and inspiration we will nonetheless make look easy, shocking,
and inevitable.) And while our finish is years away, we promise it will be worth the wait: A sensation, a true
coup de theatre.
[After
that beginning, I think I need a gin fizz and a fan. Back in a minute.]
As I say, this is a duo performance of a variegated holly and a dancer-choreographer, yours truly. Let me introduce my partner, this female variegated holly. She's a rare bird indeed because she's a variegated
American holly—the only one in an otherwise dull-green family. (That's why her Latin name is, with rueful honesty,
Ilex opaca. "Opaca" means dull; yes indeed, it's a cousin of "opaque.")
She's clearly still a youngster, all knees and elbows, not yet even hinting at her voluptuous as well as statuesque maturity.
Even so, many of her gifts are already before us:
— Leaves heavily margined in cream and white (and displayed so nicely against the backdrop of green boxwood and frost-killed hardy hibiscus foliage).

And, of course, just like the rest of the American holly family, these leaves are evergreen as well as spiny enough to be completely deer-proof.
— Hardiness through Zone 5, so you gardeners in low-land Vermont, plant away.
— Red berries through Fall and (well, let me track this for you this year) mid-Winter.

Hollies with berries are always females, and they (almost) always need the stud service of a lowly male holly to berry their best. This holly's still a bit sparse in the berry, so to speak. Is that the nature of the girl? Or perhaps she needs a man nearby, not just a dancer-choreographer.
Checking out the neighborhood for male American hollies...and there's a massive one not fifty feet away in the adjacent property. It doesn't have any berries at all, even while this one does. If even this young variegated female has berries, the far larger and older tree would also have them...if it were also a female. And so it's a male—and so either this variegated tree is just getting into a berrying mood or isn't all that interested in the first place. (More on holly berries in today's post.)
— A preference for full sun that doesn't rule out a long and happy life with some shade.
— A remarkable flexibility about (Spring) pruning: Do it a lot, a little, or never, and she's still enthusiastic. And while heaven forfend that you would ever need or want to get out the chainsaw and stump the old girl, she'll sprout forth promptly if you do.
Not to worry: I'm never going to recommend more than a nip and tuck for my baby girl, because she's
soooo special already. Yes, she may well be a child of the shininess-challenged
Ilex opaca family, but that's the reason why her given name, Stewart's Silver Crown, is all the more tantalizing. Even more astounding, the reality of the "silver crown" only exceeds whatever you're imagining: As she matures, the foliage at top of the tree (and only the top) will be
entirely cream-white. The bark on the young twigs too. All of it,
pure ivory white.
By the second year, that creamy foliage acquires some chlorophyll (and the bark of the young twigs matures to boring tan), but the new foliage growing up from it is the new generation of all-white growth. Year after year, the tree is never without a "silver crown."
[Back to my David Merrick impersonation.] But even this silver crown—unique not just in the world of hollies but in the world of plants overall and everywhere—
still isn't the finale of the act.
Ladies and Gentlemen, kindly recall that this is a
pas de deux, a partnership. Having a silver crown, then, is only the beginning of climax. That part of our performance comes right from the casting. So what could possibly top it?
Three clues: 1. Holly is amazingly amenable about being pruned. 2. The way to encourage any holly to grow the maximum amount of new growth is to prune it in early Spring. 3. Stewart's new growth is pure white—but only at the top of the tree.
And so, the envelope, please: Year by year I'll prune away my Stewart's lower branches, whose foliage is "only" the usual variegation. And year by year (starting this very Spring), I'll lightly prune the very top of the Stewart, so it branches into two, four, eight, sixteen, a zillion tops, all crowding together. Each of which will produce its own "silver" crown.
In who-knows-how-many years, then, the tree will be a broad mound of pure-white foliage atop a thick trunk. This Silver Crown will have grown into its essence: It will be all crown, or rather, all
crowns. A full set of crowns, a collection, a congeries: A crowning glory indeed.
Or at least that's the plan. Admittedly, it's more of a high-wire act than a Fred-and-Ginger sashay. There's suspense involved, not just sparkle, not just skill. How much of the "normal" variegated foliage is needed to sustain the growth of all of that pure-white (and therefore chlorophyll-free) new growth each Spring? Will the look therefore be more like a giant and thickly sour-cream-frosted green cupcake on a stick? Or will the outer crowns be nodded outward by density of the more central crowns, so that the cupcake will become frosted on the sides too?
In truth, who can say? To my knowledge, my lifelong dance—pruners at the ready—with this Stewart's Silver Crown is a "Star Trek" moment. Stewart and me, holly and gardener, we're both Going Where No Man Has Gone Before.
