Nigella damascena : semis, culture et entretien

Botany

The love-in-a-mists include around twenty species of annual plants native to Europe, Asia, and North Africa. The most well-known is the Love-in-a-mist, Nigella damascena. It can be found around the Mediterranean, in southern Europe, and in North Africa. It grows wild in France, alongside a few other species of love-in-a-mist. It is commonly found in fields, fallow land, along roadsides, and in rocky areas.

The name “love-in-a-mist” comes from the Latin niger: black, referring to the colour of its seeds. In French, it is sometimes called Cheveux de Vénus (Venus’s Hair), due to the fineness of its feathery foliage, which is divided into linear segments. In English, love-in-a-mist is known as Love in a mist (referring to the misty foliage) or Devil in the bush.

The love-in-a-mist belongs to the family of buttercups, the Ranunculaceae. This is a large family, comprising over 2,000 species of predominantly herbaceous plants, many of which are toxic. Hellebores, aconites, columbines, clematis, delphiniums, and anemones are all part of this family.

The Love-in-a-mist is a small plant: it measures between 20 cm and 50 cm in height, sometimes reaching up to 60 cm, with a width of 20 to 25 cm. It grows taller when cultivated in a substrate rich in organic matter. It is best positioned at the front of borders, in front of taller plants. It forms clumps that expand over the years, consisting of upright stems, sometimes branched, but can also be single.

The love-in-a-mist flowers in summer, typically between June and August, sometimes extending into September. The flowering period can be earlier or later depending on when you sowed the seeds. It does not last very long… but it is quickly followed by decorative fruits!

The love-in-a-mist bears flowers in rather soft, pastel shades. They are often light blue, but can also be white or pink, sometimes almost red, or mauve-purple. For instance, the varieties ‘Persian Rose’ and ‘Mulberry Rose’ have stunning pink flowers. The eastern love-in-a-mist, Nigella orientalis, stands out with its yellow flowers! There are also seed mixes that produce an assortment of flowers in various colours. It is common for love-in-a-mists to display beautiful nuances, with their shades varying from one flower to another. Similarly, it often happens that the colour of a single flower changes slightly over time. For example, the flowers of the ‘Mulberry Rose’ variety are initially soft pink when they bloom, becoming a more pronounced pink later. In the case of the ‘Dwarf Moody Blue’ variety, they are violet-mauve, evolving into a blue shade. Sometimes, the flowers provide a stunning contrast between the sepals, which are often white or light blue, and the pistils/stamens, which can be very dark, black, or burgundy.

The love-in-a-mist has very beautiful star-shaped flowers, usually solitary and borne at the ends of the stems. They measure between three and five centimetres in diameter. They consist of five to twenty-five petaloid sepals (which resemble petals), coloured. These surround five to ten petals, often smaller, which sometimes contain nectar consumed by insects. Love-in-a-mist flowers are hermaphroditic: each has male (stamens) and female (pistils) organs. Thus, at the centre of the flower, there are five to ten pistils gathered and upright, surrounded by a large number of stamens. The styles, long and thin, resembling the segments of the leaves, are often curved towards the stamens to facilitate fertilization. The pistils and stamens are generally very decorative, adding more detail and refinement to the flower, and they sometimes offer a beautiful contrast with the lighter sepals. Directly beneath the coloured sepals, the love-in-a-mist bears five bracts divided into fine strips, resembling the rest of the plant’s leaves. They are all inserted at the same level. The flower appears nestled in a silky bed of very fine leaves. Some love-in-a-mists stand out with very different flowering, such as Nigella ‘Blue Stars’, which has small five-petalled blue-violet flowers, with numerous stamens at the centre. They have a much simpler appearance than other love-in-a-mists!

Feel free to use love-in-a-mist flowers to create bouquets! They hold up quite well in a vase.

The leaves of the love-in-a-mist are divided into extremely fine segments. They are laciniate, making them very decorative. They have a misty, light, feathery appearance. Their fineness gives the plant its name Cheveux de Vénus. The leaves of love-in-a-mist are alternate, arranged one after the other on the stem. They measure between 8 and 15 centimetres in length and are light green in colour. The foliage of the love-in-a-mist is quite characteristic, allowing for easy identification of the plant, even when it is still in the seedling stage.

The fruits of the Love-in-a-mist are very decorative. They are large, globular capsules, swollen, and turn brown at maturity. They are surrounded by dried, very fine bracts all around, and they also bear thread-like, upright styles at their tips. The capsules are divided into different chambers that contain the seeds. They open when ripe, releasing numerous small black seeds. These seeds have three faces and are wrinkled, bearing striations. Although it is an annual, the love-in-a-mist self-seeds spontaneously, allowing it to persist in the garden. You can cut the stems bearing the capsules and incorporate them into dried bouquets. They are very decorative and original! However, do leave some fruits in place to allow the love-in-a-mist to self-seed spontaneously!

Sowing

Where to sow nigella de Damas?

Sow nigella directly in open ground, in full sun or in a slightly shaded position. In too dense shade, its flowering may be less generous. Nigella prefers rich soils but can also thrive in poor soils. It is a relatively undemanding plant that can grow in any type of soil. It will be taller in nutrient-rich soils, but may develop more foliage at the expense of its flowering. Nigellas prefer soils with a neutral pH.

Nigella de Damas appreciates well-draining substrates, where water easily infiltrates. It grows very well in sandy soils. If your garden soil is heavy, compact, and retains water, we recommend adding draining materials: pumice, gravel, or coarse sand. Nigella is an easy plant that requires little: it is perfect for occupying areas of the garden where the soil is poor and dry, rocky. You can sow it on a slope or in difficult corners of the garden.

Nigella is a relatively low plant: place it preferably at the front of flower beds, just in front of taller plants. It can also help fill gaps in the flower beds. Don’t hesitate to sow it alongside other annual plants (poppy, cosmos, etc.)

You can grow it in a pot or in a planter, which you can place on your balcony or on a windowsill.

When to sow?

Nigella is often sown in spring, from March to May. However, it can also be sown in autumn, especially if you live in a region where winters are relatively mild; in this case, it will flower earlier. The ideal is to stagger the sowings, so that the flowering occurs over a longer period!

How to sow nigella de Damas?

Sowing nigella is very easy! Preferably place it directly in its final location, as its roots are fragile and do not like to be disturbed.

In open ground:

1. Prepare the soil by breaking up clumps and removing the largest stones, roots, and weeds, to obtain a homogeneous surface made of fine soil. Optionally, add some well-decomposed compost. Level the ground so that the sowing surface is flat.
2. Sow by scattering the seeds on the surface of the soil. We recommend broadcasting for a fairly natural effect. You can also use a seed drill.
3. Cover with a thin layer of potting soil, then lightly firm down.
4. Water gently, in a fine spray.

Keep the soil moist until germination, which will occur in one to two weeks. Then, thin out the seedlings by removing some of the young plants. Those that remain should be spaced about twenty centimetres apart.

In a pot:

If you wish to grow it off the ground, you can sow nigella de Damas in a pot or planter. Place a layer of drainage (gravel, broken pot pieces, or clay balls) at the bottom of the pot to allow water to drain. Then, add a mixture of potting soil and coarse sand, scatter the seeds on the surface, and water in a fine spray.

Maintenance

Love-in-a-mist requires very little maintenance, apart from occasional watering during hot weather and some weeding. Those grown in pots will need more frequent watering than those in the ground, as the substrate dries out more quickly.

We advise you to leave the faded flowers on the plant, without pruning them, to enjoy the decorative capsules that will form and allow the plant to produce seeds. You can either let it self-seed or collect the seeds for your own sowing or to give away! Although love-in-a-mist tends to self-seed spontaneously, it is not invasive… It generally fills in gaps in borders.

You can weed the clumps of love-in-a-mist by removing the weeds that sometimes sneak in. Weeding is especially important when the capsules are present, to allow the seeds to settle on bare soil and self-seed easily. Conversely, it is easy to spot the young shoots of love-in-a-mist, so you can remove them if they spread to an undesired location.

Feel free to harvest love-in-a-mist flowers for bouquets! There is a chance that cutting them will slightly prolong the flowering; however, this will prevent you from enjoying the decorative capsules. Try to always leave a few flowers in place, both for them to self-seed and to have some capsules. Moreover, these can also be used in dried bouquets! Cut the stems while they are still fresh, and tie them all together. Then hang them upside down to dry.

Love-in-a-mist is not susceptible to diseases. It does not require any treatments! The only issue might come from slugs and snails, which sometimes eat the young shoots.

Multiplication

Nigellas multiply very easily by sowing, which you can do in open ground or in pots. When they are ripe, the capsules turn brown and begin to open slightly. This is the time to harvest them to collect the seeds! You can also let the nigellas self-seed, and possibly take the spontaneous seedlings from the garden when they are still very young. Similarly, if you need to transplant the nigellas, do so when the seedlings are still small, as they do not tolerate being moved well.

It is possible to store the seeds for later sowing. Place them in a paper bag or an envelope, which you will keep in a dry, cool, and dark place. Remember to label them (plant name and harvest date). In theory, nigella seeds remain viable for two years, but it is preferable to sow them within the year.

Over the years, the flowers of horticultural varieties may slightly change colour. It may be interesting to buy them again to return to the original variety.

Association

Love-in-a-Mist pairs perfectly with other annual plants to create a wildflower-style border that looks very natural. You can, for example, combine it with cosmos, especially those with white flowers (like the ‘Purity’ variety). Blue and white are colours that go very well together. It will beautifully accompany cornflowers (Centaurea cyanus), the intense red flowers of poppies, or the stunning flowering of Oriental poppies. Scatter these flowers among the fine foliage of grasses (Penisetum, Stipa pennata…), and enjoy the very delicate spikes of Briza media. Plant Love-in-a-Mist alongside wildflowers, which have a lot of charm and lightness. In fact, Love-in-a-Mist is often found in wildflower meadow mixes! It can be combined with centauries, marigolds, sainfoin (Onobrychis viciifolia), wild chicory (Cichorium intybus), and especially with flax, Linum perenne. You will feel like you are in a real flower field!

Love-in-a-Mist can be paired with the fine spikes of the grass Briza media (photo Hajotthu), as well as cornflowers (photo Tauri Pärna), and poppies

Love-in-a-Mist can also find its place at the front of a perennial border. With the delicacy and very refined nature of its flowers, it pairs wonderfully with bush roses. You can place it right in front of them. Don’t hesitate to combine it with marigolds, California poppies (Eschscholzia californica), or Lychnis coronaria. It is perfect for filling gaps in borders, spaces unoccupied by other plants! Their elegance and natural charm allow Love-in-a-Mist to beautifully complement lilies (Lilium candidum, Lilium martagon, Asiatic lilies…). With this type of combination – Love-in-a-Mist, roses, lilies… – you can easily create stunning bouquets to decorate your home!

Take advantage of the different varieties of Love-in-a-Mist to play with colours! Those with white flowers will soften the brighter blooms of other plants. They have a very elegant appearance, and, when combined with roses, astrantias, and gypsophilas, you can easily achieve a very romantic garden! Plant blue-flowered Love-in-a-Mist with other blooms in similar tones: blue, mauve, and white. For an intense and deep border, Love-in-a-Mist can be associated with plants in dark shades: purple, black, brown, midnight blue…

As Love-in-a-Mist tolerates poor, dry, stony soils well, you can plant it in a rockery, alongside other sun-loving and well-draining plants. For example, with grasses, yarrow, or lavenders…

Did you know?

• A spice and a medicinal plant

Seeds of cultivated nigella, Nigella sativa, are often consumed as a spice, with a fragrance reminiscent of both strawberry and pepper. Already used in ancient Egypt, they are known as black cumin and are sometimes found in the spice blend raz-el-hanout. They can be sprinkled on salads or in dishes based on rice or vegetables… However, they should be consumed in moderation, in small quantities. Similarly, avoid consuming those from Damascus nigella; they are inedible and may even be toxic. Nigella oil is also produced, particularly interesting for its antioxidant and anti-inflammatory properties. It is used externally for skin or hair care, but also internally, where it can be added to salads or various dishes.
