Germination & Seedling
2-3 weeksSeeds sprout in 7-14 days with warm temperatures. Seedlings develop simple leaves and begin establishing a taproot system.
Keep soil lightly moist but not waterlogged. Provide bright light and protection from intense heat during first few weeks.
Vegetative Growth
4-8 weeksYoung plant develops branching stems with small, succulent-like gray-green leaves. Growth is slow to moderate.
Water sparingly; allow soil to dry between waterings. Begin hardening off transplants before moving to final location. No fertilizer needed.
Establishment & Branch Development
2-4 monthsPlant develops woody stems and spreads laterally. Foliage becomes denser and more silvery-gray. Can reach 3-6 feet tall and wide.
Minimal water after first season. Prune lightly to encourage bushier form if desired. No fertilizer required; tolerates poor soils.
Mature & Flowering
Ongoing, 6+ months after plantingEstablished shrub produces small, inconspicuous flowers (greenish or reddish) that may develop into small berries.
Continue drought management. Harvest mature leaves regularly to encourage new tender growth. Tolerates neglect well.
Harvest Ready
6+ monthsPlant produces abundant usable foliage throughout the year in suitable climates. Leaves are tender and flavorful when young to semi-mature.
Pinch off young leaf tips regularly for culinary use. This encourages bushy growth and provides continuous harvest.
