Description
Introduction to Aquilegia Mc Kennas Giant
Aquilegia (Aquilegia vulgaris), commonly known as Granny’s Bonnets or Columbine, is a herbaceous perennial belonging to the Ranunculaceae or buttercup family. Native to Europe, Aquilegia forms clumps from a woody rootstock and features fine-stemmed, often blue-green foliage. The leaves are divided into small, fan-shaped leaflets, resembling fern fronds. Above the foliage, bell-shaped flowers are borne on long stems, showcasing a variety of bi-coloured blooms in hues of pink, red, purple, white, and yellow.
Growing Aquilegia ‘McKenna’s Giant’ in Different Climates
Aquilegias can be grown across Australia but particularly thrive in temperate climates with cool to mild summers, moderate winters, and ample moisture. They excel in regions that avoid excessive heat and humidity. They typically perform best in locations with full sun to partial shade, though in warmer climates, they benefit from some protection against intense afternoon sun. Regular watering to maintain consistently moist soil is crucial, especially during active growth and flowering.

Plant in full sun to partial shade, providing afternoon shade in hotter areas. Use well-drained, organically rich soil and apply a thick layer of mulch in early spring to conserve moisture and regulate soil temperature while the plant establishes. Regular watering is essential, especially during dry summer months. In winter, provide light watering if rainfall isn’t sufficient and the soil becomes significantly dry, but avoid overwatering to prevent root rot. Protect the plant from strong winds and extreme heat throughout the year to support its health and vigour.
Arid Climates
In arid climates, such as those in parts of South Australia, Western Australia, and the Northern Territory, Aquilegia ‘Mc Kenna’s Giant’ requires extra care to ensure adequate moisture. These regions experience hot, dry conditions with minimal rainfall. Plant in partially shaded areas to shield the plant from intense afternoon sun. Apply a thick layer of mulch in early spring and refresh it in late autumn to conserve soil moisture and regulate temperature. Frequent watering is essential to keep the soil consistently moist, especially during the growing season. In winter, when moisture may be scarce, monitor soil dryness and water lightly if needed to prevent the soil from becoming too dry.
Semi-Arid Climates
In semi-arid climates, such as parts of New South Wales, Queensland, and Western Australia, Aquilegia ‘Mc Kenna’s Giant’ thrives with attentive watering and soil care. These regions have hot summers with occasional rainfall. Plant in partial shade to protect from intense sun and apply a thick layer of mulch in early spring to conserve moisture and keep roots cool, refreshing it in late autumn. Regular, deep watering is crucial to maintain soil moisture, especially during growth and flowering. In winter, when conditions may still be dry, check the soil regularly and water sparingly if it becomes too dry.
Tropical Climates
Aquilegia isn’t ideally suited for tropical climates, but with careful attention, it can still thrive. Choose a location with partial shade to shield it from the intense midday sun and plant in well-drained, organic-rich soil to retain moisture. Regular watering is crucial, especially during dry spells. However, due to the rainy season, it’s important to monitor watering to avoid overwatering, as frequent rain can lead to root rot. Mulch helps conserve moisture and keeps the roots cool; apply it in early spring and refresh it in late autumn. In winter, keep the soil slightly moist but not soggy, as tropical winters can still be dry. Protect the plant from strong winds and excessive heat to ensure it remains healthy and vigorous.
General Care Tips
- Soil: Ensure the soil is well-drained yet moist and rich in organic matter.
- Watering: Keep the soil consistently moist, especially during growth and flowering, while ensuring it remains well-drained.
- Sun Exposure: Full sun to partial shade, with protection from intense afternoon sun in hotter climates.
- Mulching: Apply a thick layer of mulch to conserve moisture, regulate soil temperature, and protect roots from extreme conditions.
- Fertilising: Apply a balanced, slow-release fertiliser or well-broken-down animal manure in early spring.
- Pruning: Prune old foliage once it has turned brown, after the flowering season, typically in late summer or early autumn.
By tailoring your care practices to your specific climate, you can enjoy the beauty and charm of Aquilegia ‘Mc Kenna’s Giant’ in your garden.
Receiving and Planting Aquilegia
When you receive your Aquilegia ‘Mc Kenna’s Giant,’ it’s best to plant them as soon as possible to ensure they remain in top condition, with winter being an ideal time. This will help minimise transplant shock and allow their root systems to establish before spring growth.
Begin by inspecting the plants for any damage or disease, and check that the roots are healthy—not too wet or dry. For bare-root plants, soak the roots in water for 1-2 hours before planting. Choose a sunny to partially shaded spot (refer to your climate requirements) to protect them from harsh afternoon sun, especially in warmer climates. Plant in well-drained, organic-rich soil, and enhance it with compost or well-rotted manure to improve fertility and structure.
Space the plants 30-40 cm apart, ensuring the roots are just below the surface and the crown is level with the soil. After planting, water thoroughly and keep the soil consistently moist until the plants are well-established. During the growing season, water regularly to maintain even soil moisture, aiming for about 1 inch (2.5 cm) per week through rainfall or irrigation. Once established, Aquilegia can tolerate some dryness but performs best with consistent moisture. Mulching will help retain soil moisture and reduce the need for frequent watering. Avoid letting the soil dry out completely, as this can stress the plant and reduce blooming. If needed, you can apply a balanced, slow-release fertiliser in early spring to support vigorous growth and flowering.
While resilient, providing shelter from strong winds and staking taller varieties can prevent damage to their delicate stems.
If immediate planting isn’t feasible, store the roots in a cool, dry place to prevent them from drying out. To keep them in good condition until you’re ready to plant, you can wrap the roots in damp newspaper or sphagnum moss. For rehydration before planting, soak the roots in water for 1-2 hours. Aim to plant them as soon as possible to minimise stress and ensure they get the best start.
How to Divide and Replant Aquilegia
While they can thrive undisturbed for several years, dividing them every 3-4 years rejuvenates their vigour, ensuring strong flowering seasons and preventing diseases.
To divide Aquilegia ‘Mc Kenna’s Giant,’ start in early spring or late autumn when the plant is not in active bloom. Water the plant thoroughly the day before dividing to ensure the roots are well-hydrated. Carefully dig around the plant, lift the clump out of the ground, and gently shake off excess soil to expose the root system. Use a sharp, clean knife or garden fork to divide the clump into smaller sections, ensuring each section has a healthy portion of roots and at least one or two growth buds. Replant each division in well-drained, organically rich soil, spacing them 30-40 cm apart and keeping the crown level with the soil surface. Water the newly planted divisions thoroughly and maintain consistent soil moisture until they are well-established. Apply a layer of mulch around the new plants to retain moisture and regulate soil temperature.
please note: These plants may self-sow, meaning they can propagate naturally by dropping seeds that germinate and grow into new plants.
Managing Pests and Diseases in Aquilegia
If they become overgrown, Aquilegia can be susceptible to powdery mildew. To address this, remove affected plants and improve air circulation by thinning out crowded growth. Additionally, keep an eye out for thrips and aphids, as they can occasionally pose problems. Protect new growth from snails and slugs, which may also be a concern.
Achieving Drought Tolerance in Aquilegia Plants
Aquilegia plants typically take about 1 to 2 years to become drought tolerant once they are well-established. During the first growing season, it is crucial to provide consistent moisture to help them establish a strong root system. Once established, Aquilegia can tolerate some periods of dryness, although they will still perform best with regular watering, especially during prolonged dry spells.
In winter, Aquilegia generally requires less water due to cooler temperatures and reduced evaporation. However, if the winter is particularly dry and the soil is not receiving enough moisture from rain, you should water sparingly to keep the soil from completely drying out. Ensure that the soil remains just moist enough to prevent root stress, but avoid overwatering as the plant’s growth slows down during the colder months.
Summary
Aquilegia is perfect for both beginner and experienced gardeners. Whether used as foreground plants, in pots or borders, or for indoor arrangements, they consistently deliver beauty year after year.
