Dahlias vs. Zinnias
While both Dahlias and Zinnias are unquestioningly beautiful blossoms, that doesn’t mean they are ideal for every garden. Both possess their own set of pros and cons, and it is essential to know what they are before adding them to the fragile ecosystem that is your verdant sanctuary.
- Dahlias can be grown annually in any hardiness zone.
- Dahlias are easy to care for and compact.
- Dahlias will easily rebloom throughout the summer.
- Dahlias will attract butterflies.
- Dahlias are perennials as long as they are grown in their ideal hardiness zone.
- Some species of the Dahlia are protected under the Plant Patent Act from asexual reproduction.
- Dahlias will only bloom throughout summer. Although, some species of Dahlia can bloom as early as late spring.
- Zinnias can be grown annually in any hardiness zone.
- Zinnias are known to be more resistant to disease.
- Zinnias bloom early and rebloom throughout the season.
- Zinnias will bloom from late spring to frost.
- Zinnias will attract bees.
- Zinnias need to be pruned regularly, especially tall varieties.
What Hardiness Zones Do Dahlias Grow In?
Depending on the type of species, Dahlias can be grown as annuals in any hardiness zone. However, depending on their species, they can be grown as perennials in hardiness zones ranging from 8-10 or 9-11. So, that means they require a frost-free environment. Hardiness zones 8-10 and 9-11 compromise states and locales from Texas to all of California.
Dahlias require that their soil is consistently kept moist while growing.
All species of Dahlias require full sunlight, meaning they need direct sunlight on them throughout the day.
Dahlias grow well in enriched, well-drained soil. Their ideal pH level ranges from 6.5-7.0.
What Hardiness Zones Do Zinna’s Grow In?
Zinnias can grow as annuals in any hardiness zones. However, they prefer hardiness zones from 10-11. Hardiness zones 10-11 compromise states and locales of the southern United States, such as central Florida and most of California.
Zinnias require that their soil is kept moist but never allowed to get soggy.
Zinnias do well with both full sunlight and partial sunlight. Partial sunlight means they can withstand four to five hours a day without direct sunlight.
Zinnias grow well in average, well-drained soil. Their ideal pH level ranges from 5.5-7.5.
Where Are Dahlias Native To?
Dahlias are native to the highlands of Central America and Mexico. Over 200 years ago, Dahlias traveled from their native land to Europe, beginning its spread from their homeland to the rest of the world. The warm climates they are indigenous to are why Dahlias require a frost-free environment if you want to grow them as perennials.
Where Are Zinnias Native To?
Zinnias, like Dahlias, are native to Central America and Mexico. But, thanks to Johann Gottfried Zinn, which the Zinnia is named, the Zinnia began its spread to the rest of the world from its homeland in the 1700s. The warm climates they are indigenous to are why Zinnias are fond of hardiness zones from 10-11 and may not do so well in colder climates especially if frost is forecast.
Dahlia vs. Zinnia: Conclusion
Since both Dahlias and Zinnias can be grown in any hardiness zone as annuals; they can bring a temporary but no less stunning addition to any garden.
All you need is the right amount of patience and time to help them bloom to their fullest. While Dahlia vs. Zinnia have their own strengths and weaknesses, whether or not to incorporate them into your garden depends on which blossom you prefer.
