Flowers are the show horses of the garden. Some gardeners grow plants solely for their colorful beauty. Some of the blooms with the most impact are also the biggest. There are a lot of options for large flowering plants if you’re looking to add giants to your beds this year. Read on for some ideas on using plants with big flowers in the garden.

Plants with Big Flowers

Sometimes bigger is better, and while a mix of flowers is nice, make sure to add some of these massive blooms to your beds for maximum impact:

  • Dinnerplate dahlia: Called dinner plate varieties, these plants produce pretty flowers of 8 to 10 inches (20-25 cm.) across. There are several types in any color you can imagine. Cultivars like ‘Hamari Gold’ and ‘Penhill Dark Monarch’ are massive dinnerplate dahlias.
  • Sunflower: This is the classic big flower for gardens and for good reason. Sunflowers are cheerful, dramatically tall, and (in the case of ‘Mammoth,’) up to a foot (31 cm.) wide.
  • Delphinium: Some varieties of delphinium, such as ‘Cobalt Dreams,’ can produce flower spikes up to 2 feet (61 cm.) tall.
  • Oriental lily: An oriental lily like the ‘Casablanca’ will produce 10 inch (25 cm.) wide flowers. Even more impressive are the tree lily types.
  • Water lily or lotus: If you have a water garden or pond, consider certain species of water lily, like Victoria amazonica, with flowers as large as basketballs. Sacred lotus also grows in water and produces large, pretty flowers.

How to Use Giant Flowers in the Garden

The best big flowers for gardens are a matter of personal taste combined with what you have room for. Follow these simple tips for basic huge plant bloom care. Before putting in plants, make sure you map out beds and determine that they can fit using appropriate spacing.

Big plants and flowers can overshadow smaller, more delicate blooms. Arrange with medium-sized flowers or large clumps of smaller flowers. The tall varieties, like sunflowers and delphinium, make a great backdrop for other plants. Of course, many of these flowers are perfect for cutting and arranging.

Huge plant bloom care is not necessarily different from that of other plants. Check the growing conditions specific to each type of plant to determine what it needs. The size of these large flowers may cause some drooping, making some type of support (such as staking) is necessary in these cases.
