I’m not going to end 2024 by muttering, “How can it be December?!” So let’s start like this: Happy holidays! Much love to you and yours! And thank goodness we’ve had some rain, so by the time you read this, the devastating Mountain fire that began Nov. 6 should finally be doused.

But the wreckage remains — some 243 structures destroyed, a quarter of Ventura County’s avocado groves blackened, power lines downed, miles of irrigation pipes melted … and a beloved perennial nursery in Somis burned and nearly shuttered.

Yet incredibly Greenwood Daylily Garden’s colorful irises survived, along with many other of its flowering perennials bred specifically to bloom and thrive in Southern California.

It’s hard to believe that plants like irises, with their frilly and frothy flowers, could be resilient enough to survive a moisture-sucking Santa Ana wind storm followed by a fire that blackened hundreds of mature avocado trees a few dozen feet away.

But the truth is, for all their delicate beauty, irises are super tough. One fall, while I was living in Central Washington, someone gave me a pile of iris rhizomes — the fleshy tubers that hold their roots. I put the pile under a tree with the best of intentions and then forgot it, only to discover the following spring that the rhizomes had rooted during the winter, under the snow, and were preparing to bloom.

You’ll find quite a list of plant-related activities in the calendar below, but first a few things I discovered about growing irises in Southern California, and why you should be growing some too:

Four of the many deeply colored, shade-dwelling native Pacific Coast iris cultivated by Bob Sussman at Matilija Nursery, named (clockwise from upper left) Red Planet Iris, Golden Honeycomb Iris (bee not included), Matilija Blue Iris and Harry’s Rootbeer Iris.

• California and the Pacific Northwest have gorgeous native irises, known as Pacific Coast irises (see the selection from Matilija Nursery above) that are shorter than their tall bearded cousins but come in an eye-popping array of dramatic colors. They grow best in shade — such as under sprawling oaks or in small, well-drained planters on a townhouse patio. Keep them out of full sun and relatively dry, since they’ll rot if they get too much water.
• Non-native bearded iris are taller than their Pacific Coast cousins and prefer full sun. They come in a multitude of colors and last a week or longer as a vibrant cut flower because there are so many buds on a single stem. I’ve had a mahogany-colored stem known as Bernice’s Legacy in a vase for eight days now — Greenwood’s owner, John Schoustra a plucked it from his garden after the fire — and the last buds are finally beginning to fade.
• However, many bearded iris varieties need freezing winters to abundantly flower in the spring and fall, which is why SoCal gardeners can be disappointed unless they seek out low-chill varieties. (Schoustra has a helpful explainer on his website.)
• December is prime time for SoCal gardeners to plant these exotically beautiful, rugged flowers, which multiply over a couple of years so you can divide them, plant more or share with others.

Which led me to the most sobering bit of news:

• Two of the region’s premier iris growers, who specialize in irises designed for SoCal’s warmer climes, were right in the path of the Mountain fire.

Matilija Nursery, a Moorpark nursery owned by “Matilija Bob” Sussman, was surrounded by the fire, which somehow skirted around the edges of his property but left his plants unscathed. The nursery lost power, which meant Sussman couldn’t refill his water tanks. He had to truck in water to keep his wind-parched plants alive.

Sussman grows and sells many native plants but specializes in native Pacific Coast irises, which produce short dramatic blooms in the spring. You can admire photos of his beautiful irises online — as sumptious and sensuous as flowers painted by Georgia O’Keeffe — but you have to visit the nursery in person to buy.

Less than a mile to the west, Greenwood Daylily Gardens fared far worse. Although the fire missed owner Schoustra’s home at the top of his hilly property, it scalded nearly half of his 40-acre avocado orchard, destroyed most of his tools and nursery equipment and reduced his covered one-sided sales area and storage buildings to charred rubble.

Heat from the Mountain Fire melted black plastic nursery pots right off the root balls of perennials at Greenwood Daylily Gardens.

Schoustra’s wholesale nursery specializes in low-chill flowering perennials such as bearded irises, day lilies, geraniums and lilacs. As a longtime landscape designer and horticulturist, Schoustra said he got tired of purchasing plants developed for colder climates and watching them underperform for his SoCal clients, which in the case of irises meant lots of sword-shaped leaves but relatively few blooms.

So in 1989 he opened the nursery to cultivate low-chill varieties that thrived in our region. He continued his landscape design work for a while but now has a day job as orchard manager of Apricot Lane Farm in Moorpark (made famous by the award-winning documentary “The Biggest Little Farm”). He also sits on the board of the Southern California Horticultural Society as past president.

Evenings and weekends are devoted to his nursery, which is mostly wholesale except on Saturdays during April, May and June. That’s when he opens up the property to tour groups and gardeners who for years have come to bask in his nursery’s blooms and buy.

Peach-colored tall bearded iris known as ‘Peggy Sue’ bloomed profusely last spring at Greenwood Daylily Gardens. “They’re probably the best ‘landscape’ pink peach for Southern California,” owner John Schoustra wrote in a text, “more vigorous, with more reblooms and better year-round foliage than the popular ‘Beverly Sills.’” The garden’s ‘Peggy Sue’ iris were recently divided and repotted, so they won’t be available to purchase until April 2025, he said.

It was hard to visualize all that lush growth a few days after the fire. Plastic pots had melted off the root balls of day lilies and irises. Hand tools like shovels were burned to nibs. Fences were twisted and blistered, rustic plywood fruit bins used for displays incinerated.

But somehow, Schoustra’s irises, daylilies and many other perennials survived. In fact, fresh green daylily shoots were poking out of the soil just days after the top leaves were charred.

The nursery does a brisk business in online sales, and that won’t change, Schoustra said. He has plenty of healthy plants to sell and was already preparing to ship out orders, just a week after the fire. He is eager for the income, because he figures that replacing his irrigation lines, avocado trees, tools and buildings will easily cost more than $100,000.

There were some plant losses, of course, beyond his avocado trees. When the fierce Santa Ana winds began before the fire, he’d moved trays of rare itoh peony seedlings to the nursery’s covered sales area to keep them from drying out. The partially enclosed rustic shelter had a handsome wood floor salvaged from an old barn, where nursery visitors could purchase plants or just rest out of the sun and admire the view.

“I thought they’d be safe here,” he said, but the shelter and its old barn floor became fuel for the fire. The plastic trays holding about $15,000 worth of peony starts were obliterated and the tiny balls of soil scalded in the heat. Some of the seedlings might survive, he said, “but we won’t know until the spring.”

However, Schoustra said he considers himself lucky. Nearby neighbors lost their homes. His home was saved, along with most of his nursery stock. And people have been incredibly kind.

Fellow horticulturists have dropped off hand tools and piles of black plastic pots to replace the ones he lost. Sean Henderson, manager of Aqua-flo’s Moorpark office, left him $5,000 worth of irrigation supplies while parts of the orchard were still smoldering, Schoustra said, and well before he had money to cover the cost, with instructions to pay when he could.

John Schoustra has found little sprigs of new growth in pots of burned daylilies. Overall, he said he feels pretty lucky.

(Jeanette Marantos / Los Angeles Times)

John Chester, his boss at Apricot Lane Farm, brought the farm’s water truck to the nursery during the fire to douse as big an area as he could, and then started a GoFundMe campaign to help Schoustra recover from his losses.

Schoustra admits that he’s bone weary right now, up before dawn, in bed around 8 p.m. and going nonstop in between, but he said all the support is inspiring.

“We’ll be ready to open again this spring,” he said confidently, poking around the ruins of his sales area. “It’ll just look a little different than before.”

After talking to Sussman and Schoustra, I realize that SoCal gardeners were lucky too. The fire could have consumed all those irises bred to flourish in our climate, so it’s kind of a holiday miracle that we still have the chance to add those flouncy pompadour flowers to our yards.

Check out Schoustra’s tall bearded options online, wait to shop in person this spring or, sometime this month take a drive to visit Sussman’s native plant nursery in Moorpark and buy yourself a gift of stunning spring color.
