From care tips to propagation methods, here’s everything you need to know about Dahlia Imperialis.
What Is Dahlia Imperialis?
Dahlia Imperialis, commonly referred to as the Tree Dahlia, is a perennial plant known for its impressive height and large, vibrant blooms. Native to Mexico, this dahlia can grow up to 10 feet tall, making it a striking addition to any garden. The plant produces beautiful, daisy-like flowers that come in shades of pink, purple, and white. Its towering stature and abundant blooms make it a standout in both garden beds and floral arrangements.
How to Care for Dahlia Imperialis?
Caring for Dahlia Imperialis involves a few key practices:
- Location: Plant your Dahlia Imperialis in a spot that receives full sun. It thrives in well-drained soil and needs at least 6-8 hours of direct sunlight each day.
- Watering: While this plant is somewhat drought-tolerant once established, regular watering is crucial during its growing season. Ensure the soil remains moist but not waterlogged.
- Fertilizing: Feed your Dahlia Imperialis with a balanced, all-purpose fertilizer every 4-6 weeks during the growing season. This helps promote healthy growth and vibrant blooms.
- Pruning: To encourage bushier growth, pinch back the tips of the stems in early spring. Remove any dead or damaged leaves to maintain plant health and aesthetics.
How to Propagate Dahlia Imperialis?
Propagating Dahlia Imperialis can be done through a couple of methods:
- Division: In late fall or early spring, you can divide the tubers. Carefully dig up the tubers, separate them, and replant them. This method helps produce new plants that are true to the parent.
- Cuttings: Take stem cuttings in early spring. Select healthy stems, cut them to about 4-6 inches in length, and remove the lower leaves. Dip the cut ends in rooting hormone and plant them in a well-draining potting mix. Keep the soil moist and provide indirect light until roots develop.

Dahlia Imperialis pairs well with a variety of other plants:
- Grasses: Ornamental grasses like Miscanthus or Pampas Grass complement the towering stature of Dahlia Imperialis and add texture to the garden.
- Perennials: Combine with perennials like Echinacea or Rudbeckia to create a colorful and dynamic garden bed.
- Shrubs: Planting it near shrubs such as Buddleia or Hydrangea can provide a lovely contrast in height and form.

Dahlia Imperialis is not considered toxic to humans or pets. However, it’s always a good practice to monitor pets and children around plants, as ingesting large quantities of any plant material can cause digestive upset.
