A Blooming Delight: Growing Columbine Flowers Indoors

Columbine flowers (Aquilegia spp.) are cherished for their striking, bell-shaped blooms and unique, delicate appearance. These perennial beauties are native to North America and have become popular garden plants worldwide. While commonly grown outdoors, columbine flowers can also thrive indoors, allowing enthusiasts to enjoy their mesmerising colors and elegant forms year-round. In this article, we will explore the steps and considerations to successfully grow columbine flowers indoors, bringing a burst of natural splendor to your living space.

Selecting the Right Columbine Variety

Before embarking on your indoor columbine journey, it is essential to choose the right variety. Columbine flowers come in a wide range of colours and sizes, allowing you to tailor the bloom to your personal taste and available space. Some popular indoor-friendly columbine varieties include the delicate Aquilegia alpina with its blue and white blooms, the vibrant Aquilegia flabellata ‘Nana Alba’ with its white flowers, and the striking Aquilegia vulgaris ‘William Guinness’ with deep purple-black petals.

Indoor Growing Requirements

Creating a conducive indoor environment is crucial for the successful cultivation of columbine flowers. Here are the key requirements to consider:


Columbine plants thrive in bright, indirect light. Place them near a south or east-facing window to provide the necessary sunlight without exposing them to harsh, direct rays that could lead to sunburn. If natural light is insufficient, consider using fluorescent or LED grow lights to supplement their lighting needs.

Columbines prefer cooler temperatures, ideally ranging between 55°F to 70°F (13°C to 21°C). Avoid placing them near heaters or air conditioning vents, as extreme temperature fluctuations can be detrimental to their growth.


Maintain moderate humidity levels around your columbine plants, as they are accustomed to the moister environments of outdoor gardens. Use a humidifier or place a tray filled with water and pebbles near the plants to raise humidity levels.

Air Circulation

Good air circulation is essential to prevent the buildup of moisture and discourage the growth of fungal diseases. Ensure proper ventilation in the growing area without exposing the plants to drafts.

Potting Mix

Choose a well-draining, lightweight potting mix with a neutral to slightly acidic pH. A mix that contains peat moss, perlite, and vermiculite will provide adequate aeration for the roots.

Propagation and Planting

Columbine flowers can be propagated through seeds or divisions of established plants. Here’s how to go about it:


Start by filling a seed tray or small pots with the chosen potting mix. Sprinkle the columbine seeds evenly over the soil surface and lightly press them down. Cover the seeds with a thin layer of fine vermiculite or additional potting mix. Keep the soil consistently moist but not waterlogged. Germination usually takes 2 to 4 weeks.


If you already have a mature columbine plant, you can divide it to create new plants. Gently dig up the plant, taking care not to damage the roots. Divide the plant into smaller clumps, ensuring that each division has a sufficient root system. Replant the divisions in separate containers with fresh potting mix.

Watering and Fertilisation

Maintaining appropriate watering and fertilisation practices is vital to the health of your indoor columbine flowers:

  • Watering: Columbines prefer consistently moist soil, but they do not tolerate waterlogged conditions. Allow the top inch (2.5 centimetres) of the soil to dry out slightly before watering again. Use room-temperature water and avoid wetting the foliage, as this can lead to fungal issues.
  • Fertilisation: Feed your indoor columbines with a balanced liquid fertiliser every 2 to 4 weeks during the growing season (spring and summer). Reduce or stop fertilisation during their dormant period in fall and winter.

Pruning and Deadheading

Regular pruning and deadheading will promote bushier growth and prolong the blooming period of your columbine flowers. To deadhead, simply remove spent flowers by pinching them off at the base. Cut back the stems by a third after the main flowering period to encourage new growth and potential blooms.

Dealing with Pests and Diseases

While columbines are generally resilient plants, they can occasionally face pest and disease challenges indoors. Keep an eye out for common indoor pests such as aphids, spider mites, and whiteflies. Treat any infestations promptly with insecticidal soap or neem oil. Additionally, ensure proper air circulation and avoid overwatering to prevent fungal issues like powdery mildew and leaf spot.

Overwintering Indoor Columbines

Columbine plants require a period of dormancy during the winter months to thrive in the long term. When the weather starts to cool down, reduce watering and allow the plants to enter dormancy naturally. Place them in a cool location with indirect light, such as an unheated room or basement, where the temperature stays between 35°F to 45°F (2°C to 7°C). Resume regular watering and move the plants back to their original location in early spring when signs of new growth appear.
