Water regularly, mulch base, protect from extreme heat/cold in first year. Do not harvest leaves.
Vegetative Growth
Years 2-3Plant produces multiple stems and dense foliage with glossy, serrated leaves
Prune lightly to encourage branching. Light harvesting of leaves can begin in year 2.
Maturation
Year 3 onwardEstablished shrub with full canopy; begins flowering and berry production
Maintain regular watering schedule. Prune after flowering if desired. Sustain harvesting.
Flowering
2-4 weeks in springSmall greenish-white flowers appear in leaf axils; tiny but fragrant
Flowering typically occurs in spring. Note: female plants produce berries; male plants needed for pollination.
Fruiting & Harvest

Uses
Native Tea Beverage
CulinaryYaupon leaves are traditionally brewed into a caffeinated tea called 'cassina' or 'yaupon tea.' The drink is smooth, slightly herbaceous, and naturally contains caffeine comparable to green tea. [source]
Digestive & Energy Support
MedicinalTraditionally used by Timucua and other Native American tribes to support digestion, circulation, and mental clarity. Contains naturally occurring caffeine and antioxidants. [source]
Sustainable Beverage Crop
HouseholdGrowing yaupon locally reduces dependence on imported tea and coffee. A single established plant can provide years of leaf harvests with minimal maintenance. [source]
Wildlife Food & Habitat
WildlifeBright red berries feed songbirds and wildlife through winter. Evergreen foliage provides year-round shelter and nesting sites for birds and insects. [source]
Ornamental Evergreen
CraftAttractive glossy foliage and bright berries make yaupon a beautiful ornamental shrub for landscapes. Can be pruned into formal shapes or hedges. [source]

Harvest Tips
Harvest young leaves and leaf tips year-round once plant is established (year 2+). Best harvest is in spring and early summer for optimal flavor and caffeine content. Use fresh or dry leaves for tea. For dried leaf storage, harvest in morning after dew dries, dry slowly in shade to preserve green color and flavor. Female plants produce bright red berries in fall; harvest berries by stripping branches or picking individually.
Fun Facts
- 🌱 Yaupon Holly is the only native North American plant species that naturally produces caffeine—the species name 'vomitoria' refers to its traditional ceremonial use in purification rituals, not that it causes vomiting.
- 🌱 Native American tribes, particularly the Timucua and Creek peoples, cultivated and traded yaupon extensively; early Spanish colonists adopted the beverage and it remains popular in the Southeast today.
- 🌱 A mature yaupon plant can produce harvestable leaves for over 50 years with minimal maintenance, making it an excellent permaculture investment.
