If you’re searching for a flower that offers height, drama, and a burst of color, look no further than Cleome, also known as the spider flower. With its long, spindly petals and towering presence, cleome can transform an ordinary garden into a show-stopping display.
I still remember planting my first batch of cleomes in a sunny corner of my yard. Within weeks, their unique blooms attracted bees, butterflies, and even hummingbirds. The best part? They were surprisingly easy to grow and required little fuss once established.
Why Choose Cleome for Your Garden? 🌸

- Visual Drama: Known for their unusual spidery flowers.
- Pollinator-Friendly: Attracts bees, butterflies, and hummingbirds.
- Low Maintenance: Grows in average garden conditions with minimal effort.
- Versatile Use: Works beautifully in flower beds, borders, or as a backdrop.
Starting Cleome from Seeds
Direct Sowing Outdoors
One of the easiest ways to grow this flower is to plant seeds directly into well-draining soil in full sun, pressing them lightly into the soil surface. Germination can take a little patience, usually between 7–14 days, but once the seedlings appear, they grow vigorously.
Indoor Sowing
If you want an early start, sow cleome seeds indoors in moist seed starting mix. Plant them about 6–8 weeks before the last frost. Transplant outdoors once the weather warms up.
👉 Personally, I prefer indoor sowing because it gives me stronger seedlings to transplant, ensuring earlier blooms.

Choosing the Best Location
The key to healthy cleome is picking the right spot.
- Full Sun: Cleome flowers grow best in full sun, producing the tallest plants and most vibrant blooms.
- Soil: The spider flower grows best in full sun in moist, well-drained soil.
- Flexibility: While Cleome performs best when planted in a spot that has well-drained soil and receives full sun, it can handle partial shade in hotter regions.
From my experience, cleomes placed in my sunniest border outperformed those in shaded spots, both in height and flower production.
