Columbines – How to Grow Eastern Red Columbine, Aquilegia Canadensis
September 20, 2018
Simple steps for how to grow and care for Columbine
Columbine, or any variety of Aquilegia are beautiful perennials that will self-seed in good growing requirements. They are hardy plants that are native to the United States. Although this article primarily focuses on Eastern Red Columbine (since that is my favorite), the conditions required for Columbine to thrive and be happy are the same for all the different varieties available. But in a nutshell, to sucessfully grow Columbine:
Columbines are generally hardy in zones 3-8. Fine your garden zone here.
Columbines prefer partial shade, and will thrive in this. But they can grow in full shade. I’ve also grown them in full sun but they will require regular watering
Will typically grow to about 2′ (70 cm) tall, but can reach 3′ (1m), and about 1-1.5′ spread (30-60 cm)
Prefer well drained soil
In the wild, or in a meadow, they don’t handle competition well and can be crowded out
Columbines will bloom for about a month, up to 6 weeks in late spring to early summer
Columbines are loved by hummingbirds (particularly the red variety) and bees
Eastern Red Columbine Facts and General Description
Columbine is a great spring garden plant, and one of our native perennials. Also known as Canada Columbine, Aquilegia canadensis, the numerous blooms are attractive and interesting to look upon. Hummingbirds love the nectar, and I’ve found that they are generally drawn to the color red. And since it is an early bloomer, having Columbine in your garden can encourage hummingbirds to build their nests nearby. The lobed leaves are attractive all summer long with different shades of green, blue, and purple. This is a great way to get some early red color into your garden, and is particularly nice for shady areas or rain gardens. I’ve grown columbine in both full sun and shade without issue. So, I’ve found them to be adaptable to a large number of environments. Columbine is one of the three flowers described in our Early Spring Wildflowers article, which can provide your garden color from March-June (depending on your zone).
The blooms of columbines look like some form of Chinese lantern or lampshade to me. It is quite beautiful to see them dangling upside down in a gentle breeze. Watching a hummingbird go from bloom to bloom, hovering underneath to reach the nectar is fun to watch, and the more you have the more hummingbirds you should see.
There are many types of Columbines
Since I live in the Mid-Atlantic I primarily focus on Aquilegia Canadensis, or Eastern Red Columbine. That is the native variety where I live, so it has evolved to thrive out here. But there are many beautiful varieties that are native throughout the USA. A few that come to mind are the blue/purple varieties of Auilegia Aplina or Olympica, and the yellow variety Aquilegia chrysantha. Your local garden center likely has several in stock throughout the Spring/Summer, and there many different seed varieties available.
How long do Columbines live?
Columbines are classified as a perennial, meaning they should come back year after year. Some varieties act more like biennials, meaning that they grow the first year, bloom the second, and then die. So, it is always a good idea to leave some of the seedlings. But I’ve had mine live for at least 3 years, and if they come back for a fourth I will be sure to update this article. There is plenty of variation in nature, so it probably depends on the species more than anything.
Columbine Growing Requirements
I’ve found this plant to be fairly tough, growing in a variety of soil. They seem to be drought tolerant, but it helps if they at least have partial shade. If they are planted close together, and there isn’t much airflow between plants you can get powdery mildew – but this generally doesn’t harm the plant. The leaves just don’t look as nice.
You should plant these in well drained soil. I’ve never really found a need to fertilize them, as they always seem to produce plenty of blooms.
I have found that the main threat to these plants is competition from other plants. In nature, they tend to grow in areas where not many plants can grow. I’ve seen them in the wild clinging to a rock on a cliff, where you wouldn’t think any plant could grow. If you put them in a flower bed, with possibly aggressive plants nearby, they may get overcrowded.
So, you can grow them in a wide variety of places, but one of the least maintenance locations for these plants is at the base of trees, or anywhere that gets shade in the afternoon. I’ve grown them in full sun many times, but know that you will likely need to water these periodically. Just inspect the leaves, and if they look thirsty, water them,.
Growing Columbine from seed
Columbine need to have cold/moist stratification before germinating. The seed requires sunlight to break the dormancy, so I usually just plant them on the surface of the soil, pressing them in. I’ve found the easiest way to germinate them is to winter sow them. You just plant them in small pots as you would with any other seed. But, you do this in the winter and set them outside to finish wintering, but keep them covered with some translucent cover.
I use a regular starter six-pack, along with other seeds that need cold stratification. Then, keep them moist, but cover them with a clear plastic cover/dome. I secure this with twine and duct tape, and set it outside. After this, the only risk you have is if you get some exceptionally warm days in the early spring. Since the plastic cover will act like a green house, you need to make sure it doesn’t get too hot. If the temperature is forecasted to get ~60 F (16 C), then you should consider moving it to the shade. If it is in full sun in this or greater temperatures, you might cook the seeds and kill them.
From germination to transplant….
Once the seeds germinate, after they get their first true leaves (after the two that are present at germination), I transplant the whole cell to a larger pot. And then just grow them until they are large enough for transplant to the garden.
Alternatively, if you collect seeds from mature plants in the summer (~July) you can just sprinkle them in a clear area. I’ve found they will germinate if they are fresh seeds from blooms. In fact, this plant will make many, many new plants through self-seeding. So, if there is not much competition it can fill in an area quite nicely.
How long will it take for a Columbine bloom if growing from seed?
You can expect a Columbine grown from seed to bloom the following season. I’ve not seen any bloom their first year, as they generally seem to just focus on getting a good root system and establishing themselves. The first year you can expect to have a small, compact plant of deep-lobed leaves.
Should you deadhead Columbine flowers?
Deadheading Columbine flowers will prolong the blooming period. I generally don’t bother, as I am a pretty busy guy. However, anything you can do to encourage more blooms should keep that area of your flower bed prettier for a longer period of time. Logically it should also bring more hummingbirds to your home to visit.
Since this plant is herbaceous, meaning that it doesn’t have a woody stem or any foliage that stays over winter, you can remove dead foliage after the plant has gone dormant. If you grow Columbines in a well kept flower bed, and wish to keep it tidy then you can remove the foliage after the plant has turned brown after you’ve had freezing temperatures. Alternatively, you don’t have to do anything. The following Spring this plant will send up new shoots/leaves weather or not you clear away the dead leaves from the previous season. So, it is just kind of up to you and what kind of garden you have.
How to collect and save Columbine Seeds
Saving columbine seeds is incredibly easy! After the blooms have finished, and the pods are dried up and crispy, the seed should be ready for harvest. Just snip off the pods and place them in a brown paper bag. Let them dry in a cool dark place for about a week, then just shake the bag up. The seed will just fall right out of the pods. 1-2 plants should produce hundreds of seeds. The seeds are very tiny, black, and very shiny. I’ve always wondered why they looked so polished. This video shows the overall process very well:
Alternatively, if you just want to get some more plants this year, you can scatter the seed where you want more Columbines to grow. They self-seed vigorously. Even if you do nothing, you are likely to get dozens of volunteer seedlings the same year the plants first bloom. These can be transplanted to other areas or shared with friends when they are very small, or in the following early Spring when the plants begin emerging.
Threats from animals eating Columbines
The other risk to these plants are rabbits eating them. I have found that if they are browsed by rabbits they can recover if they are large enough. In my gardens, I spray them with liquid fence when they emerge every week for about a month. This keeps the hungry animals away, allowing them to grow large enough to bloom nicely. Also, they typically aren’t eaten by deer – but it can happen. However, liquid fence has always worked for me, as long as I keep up with the applications.
So, plant them where they can have their own area, It can be in full sun to shade, as long as the soil will drain. Then, enjoy the early spring blooms from this flower, and keep an eye out for hummingbirds, as they are very likely to visit. As another benefit, they will self-seed heavily, so you should have no shortage of plants in your garden.
Typical Columbine Uses in Garden
As stated, Columbines are very adaptable to a wide variety of conditions. They can be great for a shady area that doesn’t get much sun or a rain garden. Due to their size, they can make a nice border on a shady side of your house. I use them under trees, and out in the open in a more ‘general’ meadow. However, if you plant them near other plants keep an eye on them to make sure they don’t get ‘crowded out’ as they don’t handle competition well.
A must for attracting hummingbirds
Growing Columbines will help to attract hummingbirds to your garden. It is one of the earliest nectar sources for them, and can encourage them to build nests nearby. If you really want to attract hummingbirds, grow multiple specimens. It is a pretty simple principal – more food, more hummingbirds!
