The flowers of Hydrocera plants are trumpet-shaped and can range in color from white to pink or purple. They are very fragrant and attract a variety of pollinators, including bees and butterflies.
Care Guide
Hydrocera plants are relatively easy to care for, but they do require some basic needs to thrive. Here are some tips for caring for your Hydrocera:
- Water: Hydrocera plants are aquatic and need to be submerged in water. Make sure to keep the water level consistent and avoid letting the roots dry out.
- Fertilization: Hydrocera plants do not require much fertilization, but you can add some aquatic plant fertilizer to the water every few weeks to encourage growth.
- Soil: Hydrocera plants do not require soil, but you can place them in a container with some aquatic plant substrate if you prefer.
- Sunlight: Hydrocera plants prefer bright, indirect sunlight. Avoid placing them in direct sunlight, as this can cause the leaves to burn.
- Hardiness Zones: Hydrocera plants are hardy in USDA zones 9-11.
Common Pests & Diseases
Hydrocera plants are relatively pest and disease-free, but they can be susceptible to root rot if the roots are kept too wet. To prevent root rot, make sure to keep the water level consistent and avoid overwatering. If you notice any yellowing or wilting leaves, this may be a sign of root rot. Remove any affected leaves and adjust the water level accordingly.
Habitat
Hydrocera plants are native to tropical and subtropical regions of the Americas, Africa, and Asia. They can be found growing in freshwater ponds, lakes, and rivers. Hydrocera plants are often considered invasive due to their fast growth rate and ability to crowd out other aquatic plants.
