Description

Aristolochia tagala, known as Philippine Aristolochia, is a tropical vine native to Southeast Asia. Its glossy heart-shaped leaves and distinctive maroon and yellow tubular flowers set it apart. These flowers, resembling a curved pipe, serve as a natural pollinator trap. Thriving in well-draining soil and partial shade, it can reach heights of 10 feet. Aristolochia tagala offers a blend of tropical allure and ecological value, making it a noteworthy addition to gardens with proper care.  Zones 9-11

Germination

To germinate Aristolochia tagala seeds, begin by preparing a seed starting tray or small pots filled with a well-draining seed starting mix, such as a blend of peat moss and perlite. Ensure the soil is evenly moist but not waterlogged. Since Aristolochia tagala seeds have a hard outer coat, scarification is beneficial for better germination. Lightly scarify the seed coat with sandpaper or a sharp knife. Then, soak the seeds in room temperature water for about 24 hours to further soften the seed coat. After scarification and soaking, sow the seeds evenly over the surface of the soil and gently press them into the soil with your fingertips. Cover them lightly with a thin layer of soil. Place the tray or pots in a warm location with indirect sunlight, maintaining a temperature between 70-80°F (21-27°C). Keep the soil consistently moist but not waterlogged by misting regularly or using a gentle watering can. Germination typically occurs within 2-4 weeks. Once the seedlings emerge, provide adequate spacing if growing in trays or transplant them into individual pots when they have developed a few sets of true leaves. Continue to care for the seedlings with proper watering, light, and nutrients as they grow into mature Aristolochia tagala plants.
