🕷️ White Queen Cleome

What it looks like

Why this variety

White Queen is the cleome for evening gardens: tall, airy plants with pure white spider flowers that glow at dusk, when the violet and pink cleomes have faded into shadow. White flowers reflect moonlight and twilight better than any color, so a White Queen drift is the backbone of a moon garden, and by day it is a crisp, clean white against green foliage and silver companions. It blooms from summer until frost, draws night-flying moths as well as day butterflies, and asks for almost nothing beyond sun and drainage.

The trade-off is the same as all cleomes: thorny, sticky, pungent foliage, and free self-seeding. Wear gloves, plant it where its scent will not offend a patio, and edit volunteers in spring. White flowers also show every speck of dirt and every visiting insect up close, which is part of their charm in a moon garden — at dusk, all you see is the glow.

If you are new to choosing between cultivars, the Varieties Matter guide explains why the name after the plant matters as much as the plant itself. White Queen is a perfect example: it is not just a cleome in the abstract, it is a cleome with a specific job, a specific history, and specific strengths.

Florida honesty: cleome is a genuine statewide annual in Florida, and White Queen is a superb Florida moon-garden plant — it loves heat, blooms until frost, and glows on warm Florida evenings when the garden is actually usable. Give it sun and drainage, let it self-sow, and plant it where you sit in the evening, so the glow is yours.

How to grow

Start seeds indoors 6 to 8 weeks before the last frost, or sow directly after frost danger — cleome seed germinates with warmth and patience. Set plants out after frost in full sun and well-drained soil, work worm castings into the bed at planting, and give them room: a mature cleome is 3 to 5 feet tall and airy, not a bedding plant. Wear gloves when handling it — the stems carry small spines — and let a few plants self-sow for next year’s drift if you want one.

Set plants 18-24 inches apart in soil with a pH around 6.0-7.5. Work worm castings into the bed at planting and mulch to hold moisture. A well-fed cleome plant rewards that care directly: steadier growth, better bloom, and a show that actually shows up.

Water & feeding

Water to establish, then water sparingly — cleome is heat- and drought-tolerant once established and sulks in wet soil. Water at the soil line, do not mulch heavily, and feed lightly: castings at planting is usually enough, because rich soil makes leggy cleome with fewer flowers. In a drought, occasional deep watering keeps it blooming; in a wet summer, drainage is the care program.

Common problems

• Thorns and pungent foliage — wear gloves when handling cleome, and plant it away from seating areas where its musky scent might offend.
• Enthusiastic self-seeding — volunteers appear freely; deadhead if you do not want them, or edit seedlings in spring.
• Wilting in dry soil — cleome wilts fast in drought; water deeply in dry spells, and do not let a young plant dry out.
• Leggy growth in shade or rich soil — lean soil and full sun make sturdier cleome; do not overfeed.
• Whiteflies and aphids in hot weather — blast with water and encourage predators before reaching for sprays.

Harvest

Cut stems for bouquets all summer, when spikes are fully colored — cleome flowers last well in water and their spidery blooms suit tall, airy arrangements, though the foliage scent means you should sniff before you commit to a dining-table bouquet. Deadhead only if you do not want self-seeding; otherwise, let a few plants seed for next year’s drift. At season’s end, pull annual plants and compost them, and edit volunteers in spring.

Saving seeds

White Queen is the cleome for evening gardens: tall, airy plants with pure white spider flowers that glow at dusk, when the violet and pink cleomes have faded into shadow. White flowers reflect moonlight and twilight better than any color, so a White Queen drift is the backbone of a moon garden, and by day it is a crisp, clean white against green foliage and silver companions. It blooms from summer until frost, draws night-flying moths as well as day butterflies, and asks for almost nothing beyond sun and drainage. It is open-pollinated — the Queen lines are true-breeding seed strains, and the Free Library notes that seeds of ‘White Queen,’ ‘Violet Queen,’ ‘Cherry Queen,’ and ‘Rose Queen’ are readily available — so seed saved from it comes true to White Queen. Cleome self-seeds freely: let a few plants go to seed for next year’s drift, and edit volunteers in spring — wearing gloves, because the stems carry small spines. The full method is in the Saving seeds section of the Cleome guide.
