Dahlias are spectacular large flowers that bloom from late summer until well into fall.

They come in a range of shapes, sizes and colors including pink, purple, yellow and orange.

Dahlias can be grown from seed or tubers and some varieties can reach 5 to 6.5 feet (1.5 to 2 m) in height. [1]

They love full sun and need at least 6 hours of sunlight each day. It’s best to plant them where they’re protected from strong winds.

Sunflowers are well-known for their massive bright yellow flowers.

As well as yellow, they also come in red, orange and white varieties.

Alliums are low maintenance perennials with large purple flowering heads measuring up to 3 to 4 inches (8 to 10 cm) that really stand out in the garden.

8. Peony

Peonies are popular perennials with beautiful big flowers in a variety of colors including pink, red, purple and white.

Zinnias are fast growing annuals with big brightly colored flowers in a range of colors including pink, yellow, orange, red and purple.

Dwarf zinnia varieties only reach 6 to 12 inches (15 to 30 cm) tall, while giant varieties can grow up to 4 feet (120 cm) tall.

    Ornamental onions are a favourite of mine. Everything about them is so striking. There are a lot of them in my neighbourhood and every year, I photograph them. A lot. I have at least 100 pics of ornamental onions. 🙂

    We are huge fans of Hibiscus and Hydrangeas. I learned recently that the acidity of your soil can have an effect on the color of your hydrangeas. I wish I lived somewhere warm where I could enjoy these flowers outside year round. Our peonies open like clock around Mothers Day and get crushed by rain by late May. I love the way they smell. My wife and I both enjoy sunflowers if we can keep the squirrels from stealing the seeds.

    I just planted Hydrangeas in the garden last summer! I absolutely love large flowers and plants because they tend to be so showy in a garden bed. I tend to grow sunflowers that become monsters which is always a good conversation starter when we have company over!

    Great post – thanks for sharing!

    Beautiful flowers! I have a hard time choosing which ones to plant. As the weather is pretty hot where I live I will have to choose one that would grow with a lot of sun.

  5. Lyosha

    Such beautiful flowers! I would enjoy having them in my garden as well when I actually have a garden, hehe

  6. Subhashish Roy

    Camellia, Protea and Sunflowers are my most favorite. Though love all. The Dahlia mostly found is the yellow color here.

    This post is SO NEEDED! I know absolutely NOTHING about growing plants and flowers and when I wanted to plant flowers or bushes along the front wall of the house that I bought 3 years ago, my first house, I did a search and, really, they give you so much information that I couldn’t consume it all. I couldn’t take it all in. I basically needed something that I could just plant and water and it would take care of itself! Even though I would love to learn about cultivating a garden because, really, gardening could be a work of art and I am an artist. But I just don’t have the time!

    You put nice big pictures so we could see what the plant looks like and then you briefly described what information we need to make an informed decision right underneath. This is a very good post for the novice like me who just wants to make her home look pretty. Thanks!
