Seedling
2-3 weeksSmall green plants with simple leaves; coloring has not yet developed
Keep soil consistently moist but not waterlogged. Provide bright, indirect light indoors. Thin or transplant when 2-3 inches tall
Vegetative Growth
2-3 weeksPlants establish strong stem and leaf structure; lower leaves remain green while upper leaves remain green
Transplant outdoors after last frost danger. Space 12 inches apart. Water regularly and fertilize every 2-3 weeks with balanced fertilizer
Color Development
3-4 weeksUpper leaves begin showing distinctive red, pink, or white patches and markings; coloring intensifies over time
Ensure full sun exposure for best color intensity. Reduce nitrogen fertilizer to encourage more vibrant foliage coloring. Continue moderate watering
Peak Foliage
6-8 weeksPlants display maximum color with painted upper leaves in full shades of red, pink, or white contrasting with green lower foliage
Maintain consistent care; deadhead any flowers if grown for foliage. Continue regular watering and occasional feeding. This is the peak ornamental stage
Late Season/Decline
Until frost or season endFoliage color may fade as temperatures cool or plant approaches end of season; flowering may increase
Enjoy remaining foliage color. If growing as perennial in warm zones, light pruning can rejuvenate plants. In frost-prone areas, prepare to remove or let frost kill plants

Harvest Tips
Painted spurge is grown ornamentally for foliage, not harvested. Cut stems for arrangements once coloring is fully developed (peak foliage stage). Wear gloves when handling as the milky sap can irritate skin. Seeds can be collected in fall if allowed to mature; they self-seed readily
