3 planted behind white Astilbe, 1 nearer the wall behind a folxglove. Also 1 over in the bed between Magnolia and Pyracantha. 1 left to maybe go in one of A’s beds.
Cleome’s can grow quite tall, up to 4 feet in some cases.
Flowering season can last for 2-3 months.
When young protect from slugs and snails.
Once established they can reproduce at a quick rate.
May need staking as susceptible to windy conditions.
Has spiny stem which needs gloves to pull when older but ok when seedlings. Good for insects.
Apparently look and smell skunky like a cannabis plant so I’m sure the neighbours will be talking.
Can be nipped back for bushier plants.
Supposed to do well on clay soil and self seed.
Self sown seeds need to be thinned, in order for the plants to become tall and bloom to their fullest capacity.
They don’t like to be transplanted.
Seeds must be thoroughly dried before storing, they mold quickly otherwise.
Cleomes make excellent, long-lasting cut flowers, but beware of the sharp little thorns when you’re picking and arranging them.

How to Start Cleome Seeds Indoors
It helps to toss the seeds in the frig for 5-7 days before you start germinating them. Do NOT freeze them, the crisper is fine for chilling.
Cleome seed is a touch particular (and different) in that it loves hot day time temperatures of 85F soil temperatures and night time temperatures of 65F.
If you keep it at a constant soil temperature of 72F (as we try to do with most annual seeds) you’ll have miserable luck getting it to sprout.
Sow and barely cover the seed.
Water with warm water in the morning to kick up the soil temperatures.
Even at the best of times, cleome is an erratic germinator so take each seedling as it develops 4 true leaves and transplant it into its own pot. Leave the seed starting pot to continue germinating.
You should see seedlings in 10 days if they’re coming and should be ready to transplant in approximately 4 weeks from putting into the seed starting soil.
How to Start Seeds Outdoors
This plant prefers to be planted outdoors and if you’re having trouble with it, try this method.
In a small “nursery” area, sow the seed the first week of May.
Use a nursery area so you can keep them watered (barely cover the seed when planting) and can transplant them from this area to their growing area. You’ll likely find the outdoor temperature fluctuations kick them into growth better than indoor growing.
You’ll be able to move them to their own growing spot in about 3-4 weeks and they’ll bloom in late July.
Once you have this plant started, it loves full sun and good soils.
The dwarf varieties will tolerate some light shade but the taller (old-fashioned) plants will flop in the shade.
