Darling Flowering Dahlia Plants at Nature Hills!

dahlia flowers

Native to Mexico, Dahlias are tuberous, herbaceous perennial plants that range from miniatures that are a few inches tall, to towering flowers that are the size of dinner plates!

Dahlia and their many varied forms are show-stopping flowers that bring a stunning rainbow of color to any garden!

There are over 40 species of Dahlias, and these plants come in a multitude of heights, sizes, colors, and petal forms that come in a dizzying array of shapes and sizes!

These include spiky Cactus, Waterlily, Single to Decorative, Pompom, Orchid and Ball, Anemone-Flowered, Collarette, Dinnerplate, and Peony flower forms of Dahlia - we're sure you'll find the right one for you!

Dahlia In The Landscape

Add Dahlias to either a garden bed or a large planter to easily create a brilliant focal point in your garden! These are vivid landing pads for pollinators and Hummingbirds!

Dahlia has leafy stems that range in height from 12 inches to more than 8 feet! Featuring a single flower per stem, but Dahlia has multiple stems on each plant and keeps pumping out the blooms until frost!

The more you cut for bouquets or deadhead the flowers as they fade, the more they will produce! No Pollinator garden, Perennial bed, cut flower border, or proper English Cottage garden should be without these magnificent extended-bloom flowers!

Planting & Care of Dahlia Tubers

care for dahlia bulbsEven though they are often referred to as "bulbs" the roots of this plant are tubers (like potatoes) and sprout from their 'eyes' and have shallow roots.


It is best to plant Dahlias in an area that gets at least eight hours of direct sunlight a day. If you live in a hot summer climate, choose a location that provides morning sun and afternoon shade.

The morning sun is best due to its drying power to clear the leaves of dew. Dahlia foliage also appreciates very good air circulation!

Choose a location that is well-drained and enriched with plenty of organic matter and water regularly. Preferring consistently moist but not soggy conditions. A 3-4 inch deep layer of arborist mulch and/or compost helps hold in moisture, reducing watering frequency, and insulating the roots.

  • Plant Dahlia about the time you plant Tomatoes in the late spring after the threat of frost
  • Or - Start indoors 4-6 weeks before your area's last frost date
  • Plant Dahlia tubers between 10-12 inches deep in loosened, enriched soil
  • Space tubers apart based on their mature spread so they have plenty of room to grow
  • Cover with soil and water in well - just enough to remove air pockets and prime the soil
  • Water again once you see new growth (the tubers need little until they are growing)
  • Transplant indoor starts once the threat of frost has passed and water in well

Tubers planted directly in the ground will start to sprout in about 3 weeks depending on your climate and weather. Once they do get growing - they take off!

Using a layer of mulch around the plant (not pushed up against the stem) will prevent water from splashing onto the leaves - carrying with it potential fungal and disease issues. This also helps keep the vegetative leaves looking cleaner! Water your plants only at the root level to avoid getting excess water on the foliage.

Deadhead blooms as they fade to encourage new blooms to quickly follow.

For larger Dahlia or gardeners that grow them in windy/storm-prone areas, a bamboo stake, trellis, or other structure will help keep your flowering stems standing tall. 

Dig and Store Dahlias For The Winter

Dahlias can be grown as perennial bulbs in the ground year-round in USDA planting zones 8 and up, but Dahlias grown in colder than Zones 2 to 7, need to be lifted in the autumn after the foliage begins to die back after a light chill. Do not let them be exposed to a hard frost where the ground freezes, as this will damage the tubers.

In very cold climates, to save your tubers for the next year, dig up the plants, remove the wilted leaves, and snip back the stems. Let them dry a bit and remove excess soil. Store in a cool, dark place in a paper bag for the winter. Mist occasionally with water to prevent them from drying out too much.

Warmer climates can leave them in the ground and simply trim back the stems in the fall. Fresh growth will appear in the spring.
