Columbine White Barlow

Columbines crossbreed with each other very willingly. If you let 'White Barlow' self-seed freely and other varieties grow nearby, the offspring from seeds will likely not be pure white or double-flowered. A mixture of colors and shapes will result. If you want to maintain a pure variety, you must remove spent flowers in time and not rely on self-seeding.

Columbines are not extremely demanding regarding nutrients. It is plenty if you heap a layer of compost around them in the spring (in March or April). If you want to support flowering, you can use liquid fertilizer for flowering perennials in May. Watch out for over-fertilizing with nitrogen – the plant would create many leaves but few flowers.

Yes, it is possible, but it requires a container with sufficient depth because Columbines have a taproot. The pot should have a diameter of at least 20-25 cm and good drainage. You must monitor watering much more carefully in a container than in a bed; the substrate must not dry out completely.

It depends on your intention. If you don't want the Columbine to self-seed in the surrounding area, cut off the spent flower stalks right at the ground immediately after flowering. This also often promotes the growth of new, fresh leaves that stay pretty until autumn. If, on the other hand, you want a wild planting and don't mind the Columbine multiplying (and offspring colors may vary), let the seed heads ripen and shed their seeds.

Columbine is classified as a so-called short-lived perennial. One plant usually lasts on a site in full strength for 3 to 4 years, after which it may start to weaken. However, because Columbines easily self-seed, they often 'travel' in the bed and renew themselves continuously, so you won't lose them.

This perennial is not demanding regarding soil, but it thrives best in common, permeable garden soil with humus content. It does not like permanently waterlogged clay soils, where roots could rot, nor extremely dry sandy soils. Before planting, we recommend mixing a little matured compost into the hole.

Columbine is a very adaptable perennial. White Barlow will bloom reliably in both sun and partial shade. In full sun, it will likely have more flowers, but it requires more regular watering so the soil doesn't dry out. Partial shade (for example, under the canopies of taller trees) is ideal for a longer flowering time and fresher leaves. Deep shade does not suit it; it would bloom very little there.

After removing it from the pot and planting it in the bed, watering is key. Keep the soil slightly moist for the first two weeks so the root ball doesn't dry out and connects with the surrounding soil. If you are planting in a sunny spot on hot days, we recommend lightly shading the plant for the first few days to prevent sun scorch shock.

'White Barlow' Columbine seedlings in containers can be planted throughout the growing season, but the best times are spring (April to May) and autumn (September to October). During spring planting, be careful that the plant isn't used to the heat of a greenhouse – if frosts threaten, it is better to harden it off gradually. Autumn planting allows the plant to root well before winter, ensuring a stronger start the following year.

The 'White Barlow' variety grows to a height of approximately 60 to 80 cm at flowering time. The leaf rosette is lower, approx. 30-40 cm. It is therefore an ideal plant for the middle parts of perennial beds, where its flowers 'levitate' above lower plants.

This is the work of the larva of a tiny fly called a leaf miner. Although it doesn't look aesthetic, it usually doesn't threaten the plant's life. You can simply pick off and dispose of the affected leaves (do not put them in the compost). Chemical spraying is usually not necessary in a common garden; mechanical removal of leaves is sufficient.

Yes, bear in mind that the entire Columbine plant is poisonous. It contains alkaloids that can cause nausea, vomiting, and heart problems if ingested. The plant is safe during normal handling and gardening, but it is important to ensure that small children or pets do not consume it. Always wash your hands after working with the plant.

The 'White Barlow' Columbine is fully frost-hardy in our conditions and requires no special winter protection. In autumn or winter, the above-ground part of the plant dies back (retracts). In spring, it sprouts again from the roots. You can remove dry leaves during the pre-spring cleaning of the bed.

Definitely yes! The 'White Barlow' variety with double white flowers is excellent for cutting. The flowers add lightness and airiness to bouquets. They last fresh in a vase for approximately 7 days. Cut the flowers when the buds are colored and beginning to open.
