Today's Show Notes
May is National Salad Month.
And if you've never grown a salad garden, this is the perfect time to begin.
An honest salad garden starts smaller than you might think.
Soft bib lettuce.
Red and green.
Mustard greens.
Arugula.
Spinach.
And Swiss chard that just keeps coming in all those glorious colors.
And don't forget the herbs.
Dill.
Flat-leaf parsley.
Cilantro.
And mint — which will take over a bit.
And you should let it.
Along with chives.
And chervil.
And then, of course, the radishes.
For the weeks before the heat sets in.
And then — don't forget the edible flowers.
Nasturtiums are worth growing for two reasons.
First, they're peppery.
And beautiful.
Second, they're a trap crop.
Plant them near whatever the aphids love.
And the aphids will find the nasturtiums first.
Other edibles include calendula.
And pansies.
Both are hardy.
Both are beautiful.
And both are right at home in a salad bowl.
Or a summer drink.
And if you don't know where to start, don't worry.
We'll come back to that.
Today's Garden History
1828 José Jerónimo Triana was born in Bogotá.
He grew up in a country of steep contrasts.
River valleys below.
And high, wind-swept uplands above.
Colombians call those uplands páramos.
Treeless alpine moorlands near the top of the Andes.
From an early age, José understood that plants belong to place.
Altitude matters.
Climate matters.
Survival shapes form.
José's father was a schoolteacher.
And he learned the way good teachers teach.
Through the senses.
Through touch.
Through naming the living things growing just outside the door.
As a young man, José joined the Chorographic Commission.
A government expedition sent across Colombia to map the land.
And catalog its natural resources.
It was during this work that José focused on quinine.
In the nineteenth century, quinine was the most reliable treatment for malaria.
It comes from the bark of the cinchona tree.
José studied cinchona closely.
Learning to distinguish species.
To identify potency.
To understand which trees truly held the medicine the world needed.
That work mattered deeply to him.
And it mattered to Europe.
In 1856, the Colombian government commissioned José to go to Paris.
To promote Colombian plants of economic value.
Especially cinchona.
Two weeks after marrying Mercedes Umaña, the couple left for France.
Paris was one of the great centers of nineteenth-century science.
Alive with botanical gardens.
Scholars.
And exchange.
José entered that world fully.
Over more than three decades, José and Mercedes built their family in Paris.
Their children were born there.
Paris became home.
All the while, he continued his botanical work.
And served as Colombia's Consul General.
José also used his plant knowledge in practical ways.
Developing plant-based remedies for everyday ailments.
Corn plasters for sore feet.
Tooth powders.
And a popular cough remedy known as Triana Syrup.
He was versatile.
Attuned to the needs of the moment.
Comfortable working at the intersection of science and daily life.
At the end of his life, his family endured a dark chapter.
He had been struck by a horse-drawn carriage.
And never fully recovered.
José died on October 31, 1890.
And just days later, his twenty-six-year-old daughter, Liboria, died in childbirth.
Two funerals in one week.
Today, José is buried in Paris.
At Père Lachaise Cemetery.
But his name lives on.
Inside Colombia's national flower.
Cattleya trianae.
2021 Cornelia Hahn Oberlander died in Vancouver.
She was ninety-nine years old.
Cornelia was born in 1921 in Germany.
In an industrial city along the Ruhr River.
Three moments shaped her life.
The first came when she was five.
Her mother, a horticulturist, gave her a small section of the family garden to tend.
Cornelia planted peas.
And her mother said:
You are going to be a landscape architect.
Seven years later, her father died in an avalanche.
Her mother raised the family alone.
Then, in 1938, Cornelia survived Kristallnacht.
She and her family fled Germany.
Eventually settling in New England.
At twenty-six, she became one of the first women admitted to Harvard's Graduate School of Design.
There, she met and married the urban planner Peter Oberlander.
The couple made their home in Vancouver.
A coastal city between the Pacific Ocean and the Coast Mountains.
Over the next seventy years, Cornelia helped shape Vancouver into a city rooted in nature.
She wrote:
I work with a concept driven by the idea that people want to be surrounded by nature — it's in our genes.
She designed more than seventy playgrounds.
And helped shape landmarks like Robson Square and the Museum of Anthropology.
"There's no froufrou here," she once said.
Pragmatic.
Clearheaded.
Her philosophy was simple.
Everyone deserves access to green space.
After her husband died, she kept working.
Continuing the projects that defined her life.
She described her work as invisible mending.
Restoring native plants so seamlessly they seemed to have always belonged.
Vine maple.
Douglas fir.
Wild ginger.
Still visible all over the Pacific Northwest.
Just four days before her death, the city awarded her its highest civic honor.
She died on this day in 2021.
And fittingly, she is buried in a cemetery she designed.
In the shade of a cedar grove she had planned decades earlier.
Unearthed Words
In today's Unearthed Words, we revisit a newspaper feature from May 22, 1937.
It appeared in The Hutchinson News.
The headline read:
Woman Mixes Fun And Work! Dr. Florence E. Meier Is Expert On Algae.
The article begins:
"It's a dark day when the elevator refuses to run to the office of Dr. Florence E. Meier of the Smithsonian Institution staff.
She has a little hexagonal room on the top floor of the flag tower, which makes it the highest office in Washington."
That line was a nod to the Smithsonian Castle.
Built in 1855.
With towers and turrets rising like something out of a storybook.
Florence worked in the tallest one.
The Flag Tower.
Getting there was no small thing.
"But sometimes the asthmatic elevator rebels, and then Dr. Meier… has to trip lightly up 11 floors on an iron ladder…"
Eleven floors.
Inside a stone tower.
Up an iron ladder.
Through a trapdoor.
Often carrying trays of specimens.
Up in that tower, Florence studied algae.
Microscopic plants gathering in green films along the edges of ponds.
The article praised her as a "pure scientist."
Someone free to follow her curiosity wherever it led.
She wrote letters to colleagues in Hungary, France, and Japan.
Debating her findings.
Building knowledge.
And she believed in balance.
Scientists can become very dull if they don't arrange a well-balanced life.
The reporter visited her apartment.
Tennis rackets by the door.
Schubert on the piano.
Books stacked beside her chair.
But later that same year, something changed.
While giving visitors a tour, Florence demonstrated the ladder.
As the elevator carried her guests downward, she stepped backward.
Waving goodbye.
Forgetting the trapdoor had been left open.
She fell through.
And broke her back.
She survived.
At the hospital, she was treated by Dr. William Wiley Chase.
Two years later, they married.
The tower that nearly ended her career.
Became the beginning of her marriage.
Florence continued her work.
Raised a family.
And lived a long life in science.
She died in 1978.
At seventy-five.
Book Recommendation
This book is part of Garden Mysteries Week.
Which means all this week's book recommendations feature tales of intrigue, plants, and poison straight from the garden.
Professor Eustacia Rose is done with murder cases.
She has a partner.
Matilde.
She has her university work.
She is ready, finally, for a normal life.
But then a murder victim turns up poisoned with hemlock.
One of the plants stolen from Eustacia's own illegal garden.
Bella Donna is the second book in Jill Johnson's series.
And by now, Eustacia feels like someone you already know.
Brilliant.
Difficult.
And completely unable to leave a poisonous mystery alone.
Botanic Spark
And finally, here's something sweet to ignite the little botanic spark in your heart.
1909 Margaret Mee was born in Chesham, England.
Her earliest memory of flowers came from walking the Chiltern Hills with her father.
He taught her how to truly see wildflowers.
By 1945, Margaret was thirty-six.
Divorced.
And searching for her purpose.
She found her footing in night classes at St. Martin's School of Art.
There, she met Greville Mee.
A fellow artist.
And her lifelong companion.
In 1952, they traveled to São Paulo, Brazil.
What was meant to be a short stay became a lifetime.
About every other year, Margaret traveled into the Amazon.
Painting plants where they grew.
She called the rarest ones "botanical dodos."
Plants she feared would vanish.
For nearly thirty years, one flower eluded her.
The Amazon Moonflower.
She saw it in bud once.
But lost it in the dark.
By morning, it had bloomed and faded.
Gone.
The flower blooms for just one night.
Open for twelve hours.
Then collapses at dawn.
In May of 1988, on her final expedition, she found one again.
This time, still in bud.
Margaret was seventy-nine.
She didn't let it out of her sight.
When darkness fell, she used a flashlight.
Watching the petals move.
She wrote:
The first petal began to move…
I was spellbound… by dawn, the flower was limp and dying.
She painted through the night.
Later that year, her book was published.
And days later, she was gone.
Killed in a car accident.
Margaret left behind more than four hundred paintings.
And a record of plants that may no longer exist.
Final Thoughts
I promised you a place to start.
Here it is.
One red bib lettuce.
One green bib lettuce.
That's your foundation.
Add one herb you'll actually use.
Parsley.
Chives.
Or mint in a pot.
Then one edible flower.
Nasturtiums are easy.
They spill.
They bloom all summer.
And you can tuck them into salads.
Or float them in lemonade.
Start there.
Because a garden doesn't begin big.
It begins with one thing in the ground.
And the decision to keep watering it.
Thanks for listening to The Daily Gardener.
And remember, for a happy, healthy life, garden every day.
