Dahlia and zinnia are two popular varieties of flowering plants. Both are members of the Asteraceae family, which also includes daisies, chrysanthemums, and sunflowers. Dahlias are native to Mexico, while zinnias originate from South America.

The main difference between dahlia and zinnia is their appearance. Dahlias have large, showy flowers that come in a wide range of colours, while zinnias have smaller flowers that are typically yellow or orange. Dahlias also have leaves that are lobed or divided into sections, while zinnia leaves are generally lance-shaped or oval.

When it comes to caring, dahlias and zinnias share some similarities. Both prefer full sun and well-drained soil. They also need to be watered regularly, especially during periods of hot weather. However, dahlias require more attention than zinnias when it comes to deadheading (removing spent blossoms) and staking (supporting the plant so it doesn’t topple over).

If you’re looking for a low-maintenance plant with colourful blooms, then zinnias might be the way to go. But if you don’t mind spending a bit more time caring for your plants and you want something really eye-catching in your garden, then dahlias are definitely worth considering!

All parts of the Dahlia plant contain toxins that can cause vomiting, diarrhea, and even death if ingested in large quantities.

If you suspect your pet has ingested a zinnia, it is important to contact your veterinarian or local animal hospital immediately.
