Typically, during the growing season, watering thoroughly once a week with approximately 1 to 1.5 gallons of water per plant should be sufficient. However, in very hot weather or if the plants are in containers, they may need water more frequently, even daily. Decrease watering in the fall as the plant prepares for dormancy. It's important to water at the base of the plant to avoid wetting the foliage, which can promote disease.
- Light
Spider flower thrives in a spot where it can receive full sun for at least six hours a day. The best lighting condition for Cleome hassleriana 'Helen Campbell' involves placing it in an area where it benefits from bright, direct sunlight, which promotes vigorous growth and abundant flowering. Partial shade is tolerated, but fewer flowers may be produced in lower light conditions.
- Temperature
Spider flower prefers warm temperatures and performs best when daytime temperatures are between 70 to 85 degrees Fahrenheit. Cleome hassleriana 'Helen Campbell' can survive minimum temperatures down to around 40 degrees Fahrenheit but is not frost-tolerant. The ideal growing condition is a warm environment with stable temperatures and protection from cold drafts and sudden temperature drops.
- Pruning
Pruning is not necessary for Spider flower, but occasional deadheading of spent blooms on Cleome hassleriana 'Helen Campbell' can encourage more blossoms and extend the flowering period. If desired, light pruning can be done throughout the growing season to shape the plant or control its size. The best time to prune is after flowering has diminished, usually in late summer or early fall.
- Cleaning
As needed
- Soil
Spider Flower prefers well-drained, fertile soil with a pH range of 6.0 to 7.5. A mix of loamy soil, peat, and perlite or sand is ideal for good drainage and aeration. Adding compost or a balanced slow-release fertilizer can enhance growth.
- Repotting
Spider Flower does not typically require frequent repotting as it is often grown as an annual. However, if grown as a perennial, consider repotting every 2-3 years to replenish the soil and accommodate root growth.
- Humidity & Misting
Spider Flower thrives in moderate to high humidity levels but is quite adaptable to different conditions. Aim for around 50-70% humidity for optimal growth, but the plant will tolerate lower levels without significant problems.
- Suitable locations
Indoor

- Life cycle
The life of Cleome hassleriana 'Helen Campbell', commonly known as Spider Flower, begins with seed germination, which is highly dependent on temperature and soil conditions, but generally occurs in spring. Following germination, the seedlings grow rapidly, developing a characteristic bushy foliage with trifoliate leaves. As the plant matures, it produces tall spires of white, pink, or violet flowers from summer through to fall, which are highly attractive to pollinators like bees and butterflies. After pollination, the flowers develop into elongated seed pods that eventually dry and release seeds for the next generation. The Spider Flower is an annual species, meaning its life cycle from germination to seed production is completed within one growing season. With the arrival of winter, the above-ground parts of the Cleome die, but the plant may self-seed, thus ensuring its presence in the garden for the following year.
- Propogation
Propogation time
Spring to Early Summer
The Spider Flower, or Cleome hassleriana 'Helen Campbell', is most commonly propagated through seeds. To propagate by seeds, it is best to sow them directly into the garden after the last frost when the soil has warmed, typically in late spring to early summer. The seeds should be scattered sparingly on loosened soil and lightly covered with about an eighth of an inch of soil. Regular watering will help ensure germination, which usually occurs within 10 to 14 days. Once seedlings are large enough to handle, they should be thinned out to prevent overcrowding, allowing for healthier growth and better air circulation among the plants.
