Red flowers in a garden is a classic and timeless look that never grows old. Fortunately, there’s a wide selection of red perennials that gardeners can select to add boldness and vivaciousness to your flowerbeds or landscapes.
There are so many different options to choose from, the hard question becomes – where do you start?
We’ve decided to make things a bit easier for you by picking out our favorite red perennials that are suitable for different levels of gardeners across a wide array of different hardiness zones. Let’s dig in and take a look at our favorites!
Amaryllis
Scientific name: Amaryllis
- Plant Size: 4-10 inches
- Sun Exposure: Partial Shade
- Bloom Time: Late December until the end of June
- Plant Zone: 8 to 10
The Amaryllis has beautiful bell-shaped flowers that bloom in deep red. This perennial can grow for many years, with flowers reappearing late fall and winter. They’re great for both indoor and outdoor growth. Because they bloom in the winter, they often make great holiday gifts that brighten up any gloomy winter day.
These plants thrive in USDA Plant Hardiness zones 6 to 8 and prefer direct sunlight. They don’t need a lot of water until their stems appear. Once you see the stem, you can gradually increase watering.
After the flower fades, make sure to cut off the flower from the stem. When the stem yellows, you can cut down to the top of the bulb. Cutting them will help them restore their energy.
Once the leaves also fade in autumn, cut them back and remove the bulb from the soil. Store the bulbs in a cool, dark area, such as a refrigerator. They’ll be ready for planting after six weeks of storage.
Anthurium
Scientific name: Anthurium
- Plant Size: 2-3 feet

They require a coarse potting mix that stays relatively moist. These plants need a good balance of bright and indirect sunlight to encourage their flowers to bloom.
In the wild, Anthuriums often anchor themselves onto other plants. So, if you notice that an Anthurium starts to bend and fall over, it’ll benefit from having additional support from a stake.
Make sure to remove browning leaves and faded flowers to help this plant to bloom again. However, if you want to collect seeds, leave the flower on the stem, and seeds will eventually appear.
