Worldwide Exotics Nursery

It was that article in the Los Angeles Times sometime in the ’90s, accompanied by a photo of Gary Hammer crouched in a rock crevice or slot canyon with a curtain of waterfall flowing behind him. The article that christened him the Indiana Jones of plant explorers. I can’t find the photo, but I did find another article written by Susan Heeger in 1992. Maybe I imagined the photo? Shortly after the article appeared I visited Gary’s Montebello retail nursery mentioned in the article and brought home an Ecuadoran polygonum that ate my parkway then climbed up the jacaranda — on no supplemental irrigation With climate change forcing record heat and prolonged drought, I appreciate more and more Gary’s scouring the world for beautiful plants tough enough for Southern California gardens. (Although the knotweed turned out to be a little too tough, even for a hell strip, and was removed.)

Gary eventually left California and moved to Mexico. And it was while he was delayed in transit, awaiting a rescheduled flight back to Mexico, that he was struck by a car on an Arizona highway in 2011, when he was 57. Like T.E. Lawrence, years of dangerous, bone-breaking adventures in foreign countries were survived to end in a vehicular accident near home.

In this 2013 tribute to Gary in Pacific Horticulture, some of the plants attributed to him include Dymondia margaretae, Cotula lineariloba, and he is credited with introducing lomandra, westringia, phormium, juncus, among so many others to SoCal gardens. Shelley adds ledebouria to the list. And considering its ubiquity, it’s astonishing to be reminded that Gary introduced Euphorbia tirucalli ‘Sticks on Fire’ here.

For a time capsule snapshot of those heady times, pre-Internet, this excerpt from the article in Pacific Horticulture sums it up:

Remember the plant lust of the mid-1980s through mid-1990s? When you would drive hours out of your way to a plant sale in another county or an out-of-the-way nursery to find something you’d never grown before? And head back home with a smile on your face because your vehicle was crammed full of things your gardening cronies would never even have heard of and couldn’t help but envy? And wasn’t it glorious?…In Southern California, Gary Hammer created that fever almost single-handedly.”

And in the intervening years since then, I somehow assumed the nursery was closed. In fall of 2020, on one of those rambling pandemic reading jags at the computer, I discovered that Worldwide Exotics, run by Gary’s friend and business partner Shelley Jennings since the ’90s, was still in business and continued to offer Gary’s plants. I immediately made the hour-long trip and met Gary’s friends and eventual business partners, Shelley and Ken Jennings. Shelley and Ken were Gary’s neighbors, working in aerospace and finance, respectively, when they jettisoned those careers and joined forces with Gary, who seemed to be having a lot more fun. Worldwide Exotics had been running for years five days a week, but the huge operation is slowing down, now open only on Saturdays from 10-4.


From Worldwide Exotics website: “By the early 90s, Shelley founded Worldwide Exotics Nursery and began collecting with Hammer. Over the years her collection has been displayed at farmers markets, botanical gardens, amusement parks, Disney Concert Hall, schools, local zoos, wildlife habitats, commercial and residential gardens, movie sets, and many more. To this day we are still propagating unusual specimens and farming 6 acres in the San Fernando Valley.”

Shelley says this agave was obtained on Gary’s last collecting trip. It reminds me of Agave ellemeetiana but that’s not a confirmed ID. The leafy plant on the right is an aroid Pinellia tripartita

I made that first trip to Worldwide Exotics maybe six months ago, taking no photos, just wandering the grounds. I may have been projecting a misplaced tinge of tragedy onto the nursery, especially with loss the leitmotif of the pandemic, and I found the subject difficult to write about. But how could the nursery be written about without mentioning Gary? And this was someone I knew only from newspaper articles! Yet apart from Gary’s untimely death, it also fills me with emotion to be transported back to my younger gardening self, one of the devotees who chased down Gary’s plants in a time prepandemic that seemed filled with more physicality, more jitterbugging around, more adventures, more wonder — just more.


This trip last weekend I was determined to shake off that introspective mood, take some photos, and just enjoy this remarkable nursery, which Shelley and Ken work tirelessly to maintain. The weather was mild, having been in the 90sF just a few days before. Yet when the timed misters went off near the office, there was a shout of approval from customers as they swarmed to the hydrated air. The grounds get baking hot, especially on the open, unshaded succulent side.

Under the shade cloth you can find bromeliads, begonias, plectranthus, ferns, hardy orchid bletilla…

The dry garden herbaceous plants are grouped at the entrance to the nursery. You drive past the succulents to the end of the dirt road to reach the office, where you can park. A hand-picked selection of plants are grouped for sale near the office, but you don’t want to miss exploring the entire nursery, because there are some real gems to be discovered.

Most plant IDs I could guess at, but for this tutti-frutti number I’ve got nothing
(Edited to add ID offered by Randy Baldwin of Eremophila racemosa)
Possibly Sea Squill, Drimia maritima
I thought I’d finally found a variegated foxtail lily but it was NFS (not for sale)

Shelley has plans to gather every plant named for Gary and take them to the horticultural department at his alma mater, Cal Poly San Luis Obispo. (In my garden, Tecomaria ‘Hammer’s Rose’ grows against the east fence.) Both Shelley and Ken are keenly aware of his legacy that permeates their remarkable nursery. But you don’t need to know any of this to enjoy one of the prime plant shopping experiences in Los Angeles on Saturdays, 9:30-4.

    WOW! Just wow. It looks like the best kind of nursery because it allows you to explore and discover. I love nothing more than NOT knowing what I might find. Needless to say, this is EXACTLY my kind of place. I’ll organize my next trip Southern California around a visit. Maybe we can go together?

  2. Denise says:

    Gerhard, it would be a blast to explore this nursery when you’re next in town. Bring a hat and good walking shoes!

  3. Elaine says:

    Oh to live closer and be able to tag around with you two. You both are so knowledgeable and I would act like the proverbially sponge. Amazing nursery. Love to poke around places like this and see what there is to find.

  4. Kris P says:

    Wow. I grew up in the SF Valley but then I was out of the area long before the nursery opened. Still, I’m surprised I wasn’t aware of it before this. Thanks for sharing your trip and the history of the place, Denise.

  5. Denise says:

    @Elaine, I wish you were closer too!
    @Kris, I’m surprised this nursery escaped my notice too up til now, but they do a lot of work with institutions and I don’t think they were advertising to the retail crowd much.

  6. Randy Baldwin says:

    Denise, Nice pics and always great to be reminded of the many plants Gary was involved with introducing. Think your Tutti-Fruitt plant is Eremophila racemosa. We called it Easter Egg Bush when we were growing it.

  7. Denise says:

    @Randy, glad you enjoyed it, and thanks so much for the ID!

  8. WOW, just wow. Thank you for the extensive photo essay and well written accompaniment.
