• Perennial herb growing 1-3 feet tall
• Produces clusters of small white flowers from May to October
• Drought-tolerant and attracts pollinators
• All parts of the plant contain a milky sap that can irritate skin

Collecting and Preparing Seeds

Collecting Seeds:

1. Wait for seed capsules to turn brown and start to split open
2. Collect the capsules in a paper bag
3. Allow capsules to dry completely, releasing the seeds

Preparing Seeds:

1. Clean seeds by removing any plant debris
2. Store in a cool, dry place until ready to plant

Germination Process

Euphorbia corollata seeds require a period of cold stratification to germinate successfully.

Cold Stratification:

1. Mix seeds with moist sand or peat moss
2. Place in a sealed plastic bag
3. Refrigerate for 60-90 days

Sowing Seeds:

1. Fill seed trays with a well-draining seed starting mix
2. Sow stratified seeds on the surface of the soil
3. Lightly press seeds into the soil, but don’t cover them (they need light to germinate)
4. Keep soil moist but not waterlogged
5. Maintain a temperature of 65-70°F (18-21°C)
6. Germination should occur in 2-4 weeks

Caring for Seedlings

Once your seeds have germinated, follow these care instructions:

1. Provide bright, indirect light
2. Keep soil consistently moist
3. Fertilize with a diluted, balanced fertilizer every 2-3 weeks
4. When seedlings have several true leaves, transplant to individual pots

Transplanting to the Garden

When seedlings are about 4-6 inches tall and outdoor temperatures are consistently above 50°F (10°C), they can be transplanted to the garden.

Transplanting Tips:

1. Choose a location with full sun to partial shade
2. Ensure well-draining soil
3. Space plants 12-18 inches apart
4. Water thoroughly after planting

Ongoing Care

To keep your Euphorbia corollata thriving, follow these care instructions:

1. Water: Drought-tolerant once established, but water during prolonged dry spells
2. Soil: Prefers poor to average, well-draining soil
3. Fertilizer: Generally not needed; can apply a light fertilizer in spring if desired
4. Pruning: Cut back stems in late fall or early spring
5. Winter care: Mulch to protect roots in colder regions

Potential Problems and Solutions

While Euphorbia corollata is generally hardy, watch out for these issues:

1. Root rot: Ensure well-draining soil and avoid overwatering
2. Aphids: Remove with a strong stream of water or insecticidal soap
3. Deer browsing: Plant near deer-resistant species or use repellents

Using Euphorbia Corollata in Your Garden

Once established, Euphorbia corollata can be a versatile addition to your garden:

• Use in wildflower meadows or naturalized areas
• Plant in rock gardens or dry slopes
