What seeds to plant now for unforgettable spring blooms

Published Nov. 1, 2024 Updated Nov. 6, 2024 2:38 PM PT

• Seeds for sweet peas and native California wildflowers should be planted in November to get the best blooms this spring.
• Sweet peas have a delicate, unforgettable fragrance that has never been successfully duplicated artificially.
• They are easy to grow in the ground and containers, and should be a part of everyone’s garden, if only to imprint their lovely scent on the senses of passersby.

At long last, November. The presidential election hasn’t helped my anxiety, but it’s been great for my garden. I can’t wring my hands while pulling weeds and planting seeds.

It’s also made me think a lot about my father, James Marantos, a patriotic military man who introduced me to the miracle of seeds. He was the son of Greek immigrants, born in tiny Caliente, Calif., and raised in Bakersfield. He spoke only Spanish and Greek when he entered first grade. He ultimately earned a college degree (in English) and fought in World War II, Korea and Vietnam. He was a lifelong Democrat who spent most his career in the Air Force, retiring as a lieutenant colonel.

I so wish we could discuss this election. He died in 2012 just before his 95th birthday, so I can only guess at what he’d say about seeing his beloved country so divided.

But I know for certain what my dad’s final word would be:

VOTE!

There are plenty of plant-related activities below to distract you from hand-wringing this month, but first, let’s talk about the seeds you should plant now to create beautiful blooms this spring: native California wildflowers and sweet peas, one of the most delicate and fragrant flowers in the world.

My father introduced me to sweet peas when I was 5, and I was stunned that something so small and fragile could have such a powerful perfume. I believe every child should have the same exposure, to imprint their senses forever with its indelible fragrance.

November is the optimum time for SoCal residents to plant these seeds, even if you’re only gardening in containers. Planting now allows the seeds to take advantage of our winter rains and develop strong root systems. Once temperatures warm up in the spring, the plants can put all their energy into blooms.

Wildflowers are easy

We have excellent SoCal sources for wildflower seeds at the Theodore Payne Foundation in Sun Valley and the Tree of Life Nursery in San Juan Capistrano, both of which sell their seeds online. The Plant Good Seed Company in Ojai also sells wildflower seeds specific to Southern California.

And one nice bonus about wildflowers: Once they bloom, most will reseed themselves, so you don’t need to keep buying new seeds every year.

The trick to successfully planting wildflower seeds is consistent moisture, said Genevieve Arnold, Theodore Payne’s seed and conservation program manager. Ideally, you mix your tiny wildflower seeds with three parts horticultural sand to one part seeds and broadcast this mix just before a good soaking rain.

But the rains don’t always happen on cue, and most of us don’t have easy access to horticultural sand, so Arnold recommends mixing the seeds with a lightweight cactus potting soil, then scattering it over ground you’ve dampened with a hose.

You can lightly rake the area afterward, “but it’s key to remember that most California wildflowers should be sown no deeper than an eighth of an inch,” she said. “And if it’s not raining, then lightly water the seeds in,” taking care not to wash them away.

If the rains don’t come, keep the area moist, but don’t soak the site, Arnold said, “because if it’s waterlogged you can create rot or conditions where fungus will form.”

The plants should sprout, but don’t expect much above-ground action until the spring, she said. What’s important is happening underground as the roots get established. If the area where you’re planting is weedy, understand those weeds will be in competition with your flowers next spring, so try to plant on as much bare ground as possible.

Sweet peas are magic

At least, that’s what I thought the first time I smelled them. The fragrance is not easily described, “but it is unforgettable,” said Glenys Johnson, who’s been been growing and selling seeds for the English Spencer variety of sweet peas through her mail-order business, Enchanting Sweet Peas, for 26 years in Sebastapol, Calif., north of San Francisco.

“People remember the scent from their childhoods; it’s a scent that connects you to other memories even if you can’t describe it,” said Johnson.

Note that all parts of the sweet pea are inedible, despite their yummy fragrance, and the flowers are extraordinary too — delicate crepe-papery blooms growing thickly on vines in a wide range of colors, like creams tipped in violet, dainty pastel pinks, near blues, deep purples and vivid oranges and reds.

The more you pick these flowers, the more they bloom, so you can easily collect many bouquets, and never worry again about air fresheners, since even a handful can fill a room with delicate scent.

“It’s never cloying,” said Renee Shepherd, whose Felton, Calif.,-based nursery Renee’s Garden offers a large selection of seeds online and at many retail SoCal nurseries.

Sweet pea fragrance “is light, like orange blossoms with a touch of honey, but you have to grow them to experience it,” Shepherd said. “They’ve never been able to make the fragrance into a perfume because it’s so undefinable. People have tried, but it never smells right. You really have to grow the real thing.”

Most sweet peas like to climb, so plant the seeds by a fence or some kind of trellis, even if they’re growing in a large container, unless you choose a couple of windowbox varieties where the sweet peas are bred to spill out of pots. Those varieties are fragrant enough to perfume a patio or balcony, but the flowers are short-stemmed, said Shepherd, so they don’t make good bouquets.

If you want flowers for cutting, choose the long-stemmed climbing varieties — both Johnson and Shepherd offer many colors and styles. (Fig Earth Supply nursery in Mount Washington also sells seeds and seedlings.)

Shepherd said in her experience, the showy Spencer varieties can struggle in hot inland areas, but other varieties flourish even in high-temp spots like Bakersfield.

Johnson likes to use bamboo poles and her teepee pole ring to create a small trellis when she sows seeds in containers. She prefers fabric pots, “the larger the better,” around 30-gallon size, to give the roots room to grow and enough weight to keep the plants from tipping over, since they can grow up to 9 feet tall.

Plant sweet peas about a half-inch deep in compost-enriched soil and keep the area moist but not soggy. As the tiny plants emerge, keep a sharp eye out for birds, gophers, snails and slugs who might find the seedlings tasty, Shepherd said.

If you have a real problem with pests, sow the seeds in flats outside to more easily protect them from critters, Shepherd said, and then plant the established seedlings in the ground in the early spring, when they should be sturdy enough to withstand nibblers.

It’s an easy tradition to establish, and you’ll be a hero with your neighbors when you offer them bouquets. “I met a woman who told me she always plants her seeds on Thanksgiving,” Johnson said. “She says she puts her turkey in the oven and her seeds in the ground while the turkey is cooking. It’s a good memory jog.”

Which reminds me: Wishing you all a safe and delicious Thanksgiving with as many friends and family as you can crowd around a table.

What we’re reading

SoCal’s Santa Ana “devil winds” have always been a given for this California native, but I never had a clue how they happened until I read this fascinating article by atmospheric scientist Ned Kleiner. Mind-blowing hint: Those hot, dry, dusty winds start with cold dense air in the high desert of southern Nevada.

“They took Knut’s teacher, you know.” So starts the chilling story by L.A. Times Letters Editor Paul Thornton about his grandfather’s teacher in Norway, Lars Nødtvedt, who was murdered by the Nazis during World War II for resisting the “Nazified curriculum” being forced on the schools. It’s just the kind of story my father would have clipped for us to read, especially with all the threats and accusations against teachers today.

A tawny handsome cougar known as P-22 looking into a remote camera in Griffith Park.

Remember the Wallis Annenberg Wildlife Crossing inspired by L.A.’s late great cougar P-22? They’ve finally constructed a near football-field-sized structure that spans the entire 101 Freeway in Agoura Hills, but there’s still much to be done before animals can cross. Next step? Adding tons of soil and 5,000 hyperlocal native plants.

And speaking about P-22, here’s a nonpolitical question to chew on over Thanksgiving dinner: If Lassie has one, along with Kermit, Godzilla and now, even Batman, why can’t L.A.’s most famous feline celebrity get a star on the Hollywood Walk of Fame?
