About

Aconitum x cammarum 'Eleanora' is a herbaceous perennial that can reach heights of up to 1 meter. It features robust, upright stems and deeply lobed green foliage. From midsummer to late summer, it produces spikes of hooded white blooms with blue-violet margins. These flowers attract bumblebees, especially those with long tongues, which are not harmed by the plant's toxins.

Care notes

Cultivation

Grows best in deep, cool, moisture-retentive soil in partial shade, but will also tolerate most soils and full sun if soil is humus-rich and protected with mulch to ensure that it is moist throughout the growing season; use protective gloves

Pruning

No pruning required except cutting back dead stems; use protective gloves

Propagation

Propagate by division in autumn or late winter; division every few years may encourage good flowering stems, though plants may be slow to re-establish; use protective gloves

Pest resistance

Generally pest-free but may be susceptible to aphids

Disease resistance

May be susceptible to fungal stem rot, powdery mildews, and Verticillium wilt
