How to grow Cleome

Cleomes are half-hardy annuals native to South America. Their common name is ‘spider flower’ because of the spray of the stamens. It’s one of my favourite flowers to add to borders as there is brilliant height and a unique shape. 

Instructions: Cleome germinates best with lots of temperature changes from hot to cold, so we sow these early in January-March under cover (I usually plant mine in Feb) and leave on your windowsill or in your greenhouse. Plant into pots in multipurpose compost. Ensure they are watered occasionally and don’t dry out. Plant out after last frosts. They may need staking if you live somewhere particularly exposed!


Flowers: July- November

Plant Position: Part to Full Sun 

Height: 1.2m

Spread: 45cm

 Tip: The stems have small spikes on them so be careful when planting them out from pots into borders.
