Members of the nightshade family, petunias are flowering plants that originated in South America and have since spread to Europe and North America. The name comes from the word "petun," an indigenous Brazilian term for tobacco. These plants are good at attracting pollinators - in fact, some species of insects and even hummingbirds have evolved to pollinate petunias specifically! There are 35 different species that range in height from less than 15 cm to over 1.2 m.
Water:
Petunias thrive in subtropical-like environments, needing consistent moisture in evenly moist, well-drained soil. They should be watered twice a week, ideally benefiting from rainwater during the growing season to promote healthy growth.
Propagation:
Propagation of petunias uses seeds and cuttings, requiring proper light, temperatures (18-24°C or 65-75°F), and nutrient-rich soil. Seed germination may need stratification or light; cuttings benefit from rooting hormone and humidity. Challenges include damping off and root rot. Maintain moisture and warmth for success.
