Cleome, commonly known as spider flowers, are beautiful and unique flowers that add a splash of color and texture to any garden. These annuals are known for their tall, spiky blooms and delicate, spider-like appearance, making them a favorite among gardeners. In this guide, we will explore how to grow and care for cleome, ensuring they thrive in your garden and provide a stunning display throughout the growing season.
Understanding Cleome: A Quick Overview
Before diving into the details of growing and caring for cleome, it’s important to understand what makes these flowers unique.
– **Scientific Name**: Cleome hassleriana
– **Common Names**: Spider flower, spider plant
– **Family**: Cleomaceae
– **Plant Type**: Annual
– **Height**: 3 to 5 feet
– **Bloom Time**: Summer to fall
– **Flower Colors**: Pink, white, lavender, purple
– **Sun Exposure**: Full sun
– **Soil Type**: Well-drained soil
Cleome plants are native to South America, and they thrive in warm, sunny climates. They are often used in borders, cottage gardens, and as background plants due to their height and striking appearance.
Choosing the Right Location for Your Cleome
The success of your cleome depends largely on where you plant them. Here are some factors to consider:
Sunlight Requirements
Cleome plants love the sun. They need full sun to thrive, which means they require at least 6 to 8 hours of direct sunlight each day. Choose a location in your garden that receives plenty of sunlight throughout the day.
Soil Conditions
Cleome prefers well-drained soil with a neutral pH. While they are adaptable to various soil types, they do best in soil that is rich in organic matter. You can improve your soil by mixing in compost or well-rotted manure before planting.
Space Considerations
These plants can grow quite tall, reaching up to 5 feet. Ensure you have enough space in your garden to accommodate their height without overshadowing shorter plants. Plant cleomes about 18 inches apart to allow for proper air circulation.
Planting Cleome: Step-by-Step Guide
Planting cleome is straightforward, but timing and technique are key to ensuring a successful growth cycle.
When to Plant
– **Seeds**: Start cleome seeds indoors 6 to 8 weeks before the last frost date. Alternatively, you can sow them directly in the garden after the danger of frost has passed.
– **Transplants**: If you buy young plants from a nursery, wait until the risk of frost has passed before planting them outdoors.
How to Plant Seeds
1. **Prepare the Soil**: Loosen the soil to a depth of 12 inches and mix in compost.
2. **Sowing Seeds**: Scatter the seeds on the surface of the soil and lightly press them down. Do not cover them with soil, as they need light to germinate.
3. **Watering**: Gently water the seeds using a fine spray to avoid washing them away.
Transplanting Young Plants
1. **Dig Holes**: Make holes that are twice the size of the root ball of your plants.
2. **Place Plants**: Carefully remove the plants from their containers and place them in the holes.
3. **Fill and Water**: Fill the hole with soil and water thoroughly to settle the soil around the roots.
Caring for Cleome Throughout the Season
Once your cleomes are planted, proper care will ensure they flourish throughout the growing season.
Watering Needs
Cleomes are drought-tolerant once established, but they need regular watering during dry spells. Water them deeply once a week to encourage deep root growth. Ensure the soil is dry between watering to prevent root rot.
Fertilizing Tips
Feed your cleomes with a balanced, all-purpose fertilizer once a month. This will promote healthy growth and vibrant blooms. Avoid over-fertilizing, as this can lead to lush foliage but fewer flowers.
Pest and Disease Management
Cleome plants are generally pest-resistant, but you should watch out for:
– **Aphids**: These small insects can be controlled with insecticidal soap or a strong spray of water.
– **Powdery Mildew**: Ensure proper air circulation and avoid overhead watering to prevent this fungal disease.
Pruning and Deadheading Cleome
Pruning and deadheading are essential practices to keep your cleomes looking their best.
Why Prune?
Pruning helps maintain the shape of the plant and encourages more blooms. Trim back any leggy or overgrown stems to promote bushier growth.
How to Deadhead
Deadheading, or removing spent flowers, encourages the plant to produce more blooms. Use clean, sharp scissors to snip off faded flowers just above a set of healthy leaves.
Companion Planting with Cleome
Cleomes make excellent companions for many other plants in your garden.
Ideal Companions
– **Zinnias**: These flowers complement cleome’s tall stature with their bold colors.
– **Marigolds**: Both plants benefit from similar growing conditions, and marigolds can help deter pests.
– **Sunflowers**: The towering height of sunflowers pairs well with cleome, creating a dramatic backdrop.
Plants to Avoid
Avoid planting cleome near vegetables or plants that require more shade, as cleome’s height and sun needs can interfere with their growth.
Harvesting Seeds from Cleome
If you wish to grow cleome again next year, consider harvesting seeds from your existing plants.
When and How to Harvest
1. **Wait for Seed Pods**: Allow the seed pods to dry on the plant. They will turn brown and begin to split open.
2. **Collect Seeds**: Use a paper bag to catch seeds as you gently shake the pods.
3. **Store Seeds**: Store the seeds in a cool, dry place in an airtight container.
Overwintering Cleome
Since cleome is an annual, it completes its life cycle in one growing season. However, you can save seeds or protect the roots in warmer climates.
Saving Seeds
Harvest and store seeds as described above for planting next spring.
Protecting Roots
In zones 10 and above, you might try mulching heavily to protect the roots and encourage regrowth. However, this is not guaranteed as cleome is not typically perennial.
Cleome, with its striking blooms and tall stature, is a wonderful addition to any garden. By following these steps, you can enjoy a vivid display of spider flowers that will captivate and delight all season long.
