I've been having bodacious success with my
Bidwill erythrinas. For a plant that's a big tree in the tropics when left to its own choices, Bidwills are surprisingly easy to handle here in pots, by being cut down to the stump each Fall, in chilly New England. And even if they were pain-in-the-ass difficult, what wouldn't you do—moral or not, legal or not, expensive or not—to have their lengthy spikes of bloom, as colorful as they are unique, right in your own gardens?

Yes indeedy, this here is one of my bidwills, doing what it loves to do each July.

And then there are those weird swollen trunks — "weird" and "swollen" both being good things in this case.
Wow are these erythrinas fun, quirky, reliable, incredible.
And, oh yes, heart-stoppingly beautiful.
More, please.
And so it was with a quickening pulse that, last year, I saw at
Seneca Hill Perennials an erythrina I'd never heard of,
Erythrina zeyheri.
What? Bidwills aren't enough? (And I have four of them, remember.) Is there truly more joy, amazement, beauty, even
shock that's possible in a garden? Let me know after you've been introduced to Zeyheri.
Let's start off easy. Too much excitement can be a shock to the system. Zeyheri is a perennial, not, like Bidwill, a tree. So on that score alone, ho-hum. Another perennial? I've got hundreds already. But take a look at this colony of Zeyheri in its native South Africa.

A real show, isn't it. Even moreso as a new citizen of my New England gardens, where vertical spikes are always welcome.
And in close-up, the flowers seem more like
kniphofias.

Fine by me: I'm working up to a "knip" collection of, oh, a modest dozen.
Here's another Zeyheri plant entirely. The color of the flowers can vary from intense red through orange and salmon clear to pinkish. Reds and oranges predominate. So then: Vertical
red spikes? Oh yes, am I interested!

When you can tear you eyes from the flowers, notice the huge leaves.
This potted youngster's leaves completely dwarf the plant itself.

I'm guessing in a more established plant that they are a weed-smothering mound of foliage three or four feet across. Heavens. One reference commented that "the leaves are long-stalked and increase in size as the summer progresses." I know just how that feels.
More on the "perennial" thing: It leads to the real kicker. Zeyheri is a "normal" perennial in that it's a committed leaf-shedder, fully expecting and even relying on a long cold-season dormancy. It retreates to a massive, woody, swollen base for the Winter.

But that base is, oh my gawd, just the tip of the iceberg.

With such leg-sized woody roots, it's no wonder that Zeyheri is "What, me worry?" about getting through several months of off-season cold and drought. I'm hoping it's the reason that the Zeyheri will also be content to snooze in my basement for six months each Winter. The low above-ground profile of the massive roots gives no warning that the plant is nearby: No wonder that one common name is "plowbreaker."

(I can't make sense of why another name is "Prickly cardinal", though. Yes, the foliage is prickly, but the cardinal thing? I leave that mystery to those with a more direct connection to the Church.)
That, then, is the list of Zeyheri's charms: Rare, prickly, big of leaf, glorious of bloom, funny of name, an easy keeper in a pot, and with what looks like the potential to be my biggest and most alarming swollen roots ever. And just like with my Bidwills, each Spring before the growth starts up I'd scrape away another inch or two of soil from the top of the pot, and, in effect, put it at the bottom of the rootball. Then those limb-like roots would arise out of the soil year by year, inch by inch, foot by foot. Ta da! Another shamelessly-manipulated
caudex for my collection.
Cearly, I was, and am, in plowbreaker lust. I had to have it. But now that I was good and ready for a Zeyheri to call my own,
Seneca no longer lists it. Drat!
Back to Google, where—huzzah!—
Penroc Seeds & Plants popped up at the top of the page. But Zeyheri's caudexs quickly get too big to ship. A relief actually: Penroc is in South Africa. Thank goodness, the plant is (they say) easy from seed.
So I e-mailed for the seed list. (Still waiting to hear from them; perhaps they're out on the veldt discovering even more wild stuff. I would be.) Meanwhile, there's time on my hands (and, I'm hoping, on yours) for some further Zeyheri research.
1. A Zeyheri
reference page (with very washed-out pictures; don't be discouraged).
2. And what I think is the
ne plus ultra reference site for plants with swollen trunks. (I can here you sigh of relief, "Finally!")
