Campanula versicolore, Campanule parfum

Campanula versicolor, the blue bellflower or fragrant bellflower, is a perennial that belongs to the Campanulaceae family. It is native to south-eastern Europe, present in southern Italy, Greece and as far as Bulgaria. It usually grows on rocky soils, often limestones, or in open forest environments of low and medium altitude.

Why this species, edible and ornamental, is it still so rare in cultivation? The blue bellflower, delicious on the plate, is also an ornamental enough species to find its place in all gardens. It is superb in clumps as in rockery, quite reliable and therefore perpetual as a vegetable.

Description of Campanula versicolor

The blue bellflower is a perennial which produces a somewhat woody stump with thick and deep roots. It develops one or more basal rosettes of leaves which not only persist, but grow slowly in winter; it widens over 50 cm over time. Its leaves are long-stalked with a relatively triangular and toothed blade, quite similar to that of the pyramidal bellflower.

In summer, from July to September, it blooms on stems 50 cm to 1.20 m high, taking up to 5 years to reach its final height.

The flowers of the versicolor bellflower are quite large, and open almost completely flat, its 5 lobes drawing a star in shades of blue: a dark heart, then very pale blue, and finally darker around the edge of the corolla, d ‘where the Latin term versicolor. The corollas are oriented slightly upwards, with a long, prominent pistil.

Their shape is reminiscent of the primrose-leaved bellflower, with which it is sometimes confused. But his perfume, rare in bellflowers, is quite characteristic: spice, He recalls clove.

The narrow flower candles of Campanula versicolor are mellifères, they nourish and attract many pollinating insects. Autofertiles, they turn into small cupules which open in September / October on fine seeds.

How to cultivate blue bellflower?

This bellflower appreciates rich and a little cool soils, which allow it to grow favorably, while also being drought tolerant and able to survive in a rock garden.

The campanule versicolore settles over time, it is reliable, but it takes a few years for it to give the best of itself from an ornamental point of view, it becomes imposing, tall and wide with the years. In addition, she does not like the transplant.

She is preferably planted in the garden in autumn or spring. From seedlings, she will be able to flower for the first time in the second year of cultivation, then she will be more and more beautiful.

To take advantage of both the flowers and the leaves, it will be interesting to plant several feet so as not to exhaust the foliage in winter to the detriment of flowering and eventually leave all the leaves on a plant cultivated for flowers.

Otherwise leaf harvests can be done the first winter on sown plants of the year, as long as you have a certain number of them.

Flower stems and seeds

Removing the deflowered flower stalk generally leads this bellflower to rise again.

Obtain seeds: in order not to exhaust the strains more than necessary, you should not allow all the seeds to mature, but only keep the amount you think you need.

The leaves are eaten raw or cooked. The raw leaves are pleasant on the palate with a flavor reminiscent of fresh peas. They are added to salads or bring a note of freshness, very appreciable in winter, placed at the last moment on the dishes.

How to multiply Campanula versicolor ?

The seeds germinate in the spring, taking advantage of the slow warming. They are very fine and are sown on the surface on a rich and draining substrate (land lightened with sand). Although the seedlings are tiny when they are born, they grow quite quickly and will benefit from being transplanted into an individual pot as soon as possible, then when they are large enough, they will be established in the garden in the spring or fall, before the roots set. a bun in the pot.

In good conditions, either on draining soil, spontaneous sowing can be expected.

Plants that are a few years old grow in several basal rosettes which can be taken with as much underground stem length as possible. This cutting takes place in the spring.

Divisions are not effective, because the fleshy roots of Campanula versicolor take too long to recover. This bellflower prefer not to be disturbed.
