About Spider Flower Mix, Cleome Seed, Cleome Seed

The Spider Flower Mix is a blend of beautiful elongated white, purple and pink annual Cleome, or spider flowers, that have been a favorite since the 1800s. This unique variety got its name for having long, thread-like individual flower clusters and seedpods. This tall flower mix can reach up to 6 feet tall and can grow equally as wide, so make sure it has enough space to thrive. Enjoy the beautiful Spider Flower blooms from early summer until the first frost. Use the striking blooms as cut flowers in an arrangement or dried.

Before Planting

Prepare for Cleome by selecting a full-sun site with well-drained soil and good air circulation. Remove perennial weeds, loosen compacted ground, and incorporate modest compost without making the bed overly rich. Prepare a fine, firm seedbed. No seed pretreatment is normally required; use fresh seed and follow the sowing conditions in the Planting guidance.

Planting

Start cleome indoors 4–10 weeks before the last spring frost, or direct sow after frost where the season is long. Keep the medium warm and evenly moist until emergence, then provide strong light and airflow. Harden seedlings gradually before transplanting into warm soil. Space cleome 18–24 inches apart.

Watering

Water cleome regularly until established, then irrigate deeply only when the soil becomes dry. Avoid frequent shallow watering and saturated conditions, which encourage weak growth or root disease.

Fertilizer

Established cleome may receive a diluted balanced or bloom fertilizer when soil fertility is low or growth begins to fade. Excess nitrogen produces soft foliage and fewer blooms.

Harvesting

Cut cleome flowers when blooms are well colored and at the opening stage best suited to display. Harvest during the cool morning with clean shears, leaving healthy foliage for continued flowering.

Tips

Stake tall cleome plants before stems lean, using loose ties that allow growth. Pinch branching types when young, deadhead regularly, and leave selected seed heads for wildlife if desired.

Pests & Diseases

Powdery mildew, downy mildew, rust, Botrytis, and damping-off may occur on cleome. Older lower leaves often show disease first; removing them opens the planting without sacrificing bloom. Avoid saving seed from plants with persistent leaf spots or distorted growth, which may indicate a transmissible pathogen.

Watch cleome buds and foliage for aphids, thrips, spider mites, Japanese beetles, slugs, and caterpillars. Look closely beneath leaves and inside buds, where early infestations are easiest to control without broad-spectrum products.
