Add Wild, Show-Stopping Height to Your Garden with Cleome Seeds

Ever walked past a garden and done an actual double-take because something tall and wispy and absolutely gorgeous was towering in the back? Chances are that was cleome. Sometimes called Spider Flower — yeah, the name's a little weird, but once you see those long, delicate stamens reaching out from clusters of frilly petals, it totally makes sense. There's nothing else in the garden world that quite looks like it.

At SeedOrganica, we carry fresh, quality-tested cleome seeds for home gardeners who want that effortless drama without the fuss. These plants shoot up 3 to 5 feet tall, bloom from midsummer all the way to frost, and attract butterflies and hummingbirds like crazy. Whether you've got a big cottage garden or just a sunny strip along the back fence, cleome fills that space with color and movement like nothing else can. It's one of those plants that looks like it took a ton of effort — but honestly? It kinda grows itself.

Explore Our Cleome Seeds Varieties

Cleome might not have the hundreds of cultivars that roses or tomatoes do, but what it lacks in sheer numbers it absolutely makes up for in personality. Each variety brings a slightly different color or growth habit to the table, and mixing them together is where the real magic happens.

Cleome Hassleriana is the classic species you'll see in most home gardens, and it's the backbone of our collection. Within this species, you've got some truly beautiful color options. Violet Queen produces rich, deep purple-violet flower heads that absolutely pop against green foliage. It's bold, it's dramatic, and it makes a statement from across the yard. If you want that "wow, what IS that?" reaction from visitors, this is the one.

Rose Queen is a little softer — think warm, rosy pink blooms that have this romantic, old-fashioned cottage garden feel. It pairs beautifully with white flowers and silver foliage plants like dusty miller or lamb's ear. Super pretty in a mixed border where you want height without heaviness.

White Queen (sometimes called Helen Campbell) is pure elegance. Crisp white flower clusters on tall, sturdy stems. It's gorgeous planted on its own in a moon garden where the white blooms practically glow at dusk. Or throw it in with the Violet and Rose Queens for a tri-color display that looks like you hired a garden designer. You didn't, but nobody needs to know that.

And then there's our Cleome Mixed packets — which give you a random assortment of pinks, purples, whites, and everything in between. Scatter 'em along a fence line and let them do their thing. The mixed planting look is honestly my favorite because it feels wild and natural and alive, like a little patch of meadow showed up in your backyard.

One thing all these varieties share? Those iconic long seed pods that dangle below the flower heads as the season goes on, giving the whole plant this layered, textured appearance. It's architectural in a way most annuals just aren't.

Gardening Insights — Growing Cleome Without Overthinking It

Here's the thing about cleome — it's basically the "set it and forget it" flower. It originally comes from South America, so it's built for warmth, handles drought pretty well once established, and generally doesn't need a lot of hand-holding. That said, a few tips will help you get the most out of it.

Sunlight: Full sun is ideal. Cleome wants at least 6 to 8 hours of direct sunlight a day for the strongest stems and the most blooms. It can tolerate a bit of light afternoon shade in really hot climates, but too much shade and you'll get leggy, floppy plants that don't flower as heavily. Sun is where cleome does its best work.

Soil: Average, well-draining garden soil is perfectly fine. Cleome isn't picky at all here. Sandy, loamy, even somewhat clay-ish soil — it'll work with what you've got. It doesn't need rich, heavily amended beds. In fact, super fertile soil can sometimes make it grow TOO tall and top-heavy, which leads to flopping over in storms. So don't overdo it with the compost. A neutral to slightly alkaline pH is great, but honestly, cleome isn't going to throw a fit over soil chemistry.

Watering: Water regularly when the plants are young and getting established. Once they're up and growing strong — maybe a foot or two tall — you can back off quite a bit. Cleome is surprisingly drought-tolerant for something that looks so lush and tropical. Deep watering once a week during dry spells is usually plenty. Overwatering is more of a risk than underwatering with this plant, so when in doubt, let it dry out a little between drinks.

Spacing & Support: Give each plant about 12 to 18 inches of room. They get bushy. If you're growing the taller varieties in a windy spot, a little staking doesn't hurt, but most of the time the stems are sturdy enough to hold their own. Planting them close together actually helps too — they kinda lean on each other for support. Garden teamwork.

Pro tip: Cleome seeds need light to germinate, so don't bury them deep. Just press them gently onto the surface of moist soil and keep 'em warm — around 70 to 75°F is the sweet spot. They can be a little slow and uneven with germination, so don't panic if things seem quiet for a couple weeks. They'll show up. Also, fair warning — the stems and leaves have small thorny spines and a slightly sticky texture. It's not a big deal, but maybe don't plant 'em right next to a walkway where people brush past constantly. Learned that one the hard way.
