Cleome Flowers

Cleome flowers (Spider flowers) are warm-season annuals in the Cleomaceae, famed for their airy, spidery blooms in pink, lavender, and white. They flower from midsummer to frost, attract pollinators, and self-seed readily; the common ornamental is Cleome hassleriana (syn. Tarenaya hassleriana).

Presentation Etiquette

Wrap stems (fine spines and sticky hairs) and include a note about the musky scent and shorter vase life. Strip lower leaves for bouquets and pair with airy companions (e.g., grasses, cosmos). For scent-sensitive settings, gift as an outdoor potted plant instead of a cut bouquet.

Ideal Delivery Time

Early morning on the day of display, during cool hours (Cleome wilts in heat and has a short vase life as cut flowers).

Care & gear

Growing tips

Cleome flowers are relatively easy sun-loving annuals, best for gardeners who can provide bright conditions and regular watering without waterlogged soil.

AspectRecommendation
LightPlant in full sun for best flowering and strong, upright growth.
WaterWater regularly to keep the soil lightly moist, allowing the top layer to dry slightly between waterings.
SoilGrow in well-drained garden soil or potting mix; avoid heavy, waterlogged sites.
TemperaturePrefers warm conditions; plant outdoors after danger of frost has passed.
Care levelModerate; requires sun, occasional feeding, and removal of spent flower heads to tidy plants.
FeedingApply a balanced, slow-release fertiliser or light liquid feed during the growing season to support continuous blooms.

Give Cleome a bright, airy position with well-drained soil so tall stems stay sturdy and flower freely all summer.

Recommended tools

  • Hand trowel - helps plant Cleome seedlings or young plants at the correct depth without disturbing roots.
  • Watering can with fine rose - delivers gentle, even watering so young Cleome plants are not flattened or waterlogged.
  • Pruning shears - makes clean cuts when deadheading tall stems, encouraging fresh blooms and keeping plants tidy.
  • Garden gloves - protect hands from potential skin irritation and provide grip when handling tall, slightly sticky stems.
  • Support stakes - steady taller Cleome plants in windy spots, preventing stems from bending or snapping.
  • Liquid fertiliser - offers quick, balanced nutrition during the growing season to support continuous flowering.
  • Mulch or bark chips - helps conserve soil moisture around roots and reduces weeds in sunny Cleome beds.
