Cyclamen HEDERIFOLIUM

Cyclamen HEDERIFOLIUM - Ivy-leaved cyclamen, Neapolitan cyclamen, Cyclamen hederifolium, Cyclamen neapolitanum.

Cyclamen is a genus of perennial tuberous plants in the family Primulaceae, comprising about 20 species distributed across the Mediterranean, Asia Minor, the Caucasus, and adjacent regions of Europe and North Africa. In nature, representatives of the genus occur in montane and foothill terrains, woodlands, forest edges, and among shrubs, preferring loose soils with seasonal moisture.

The plant forms a flattened tuber from which leaves develop on long petioles. The leaf blades are most often heart-shaped, rounded, or kidney-shaped, green, often decorated with silvery or marbled patterning. A compact rosette is formed, with leaves and peduncles emerging directly from the tuber.

The flowers are solitary, nodding, situated on tall flower stalks, and distinguished by petals reflexed backwards, making the silhouette of the plant easily recognizable. Coloration varies from white to pink, purple, and lilac. Flowering in different species is observed in autumn, winter, or early spring. After pollination, the flower stalk coils spirally and presses the fruit to the soil.

The fruit is a spherical multi-seeded capsule opening by valves. The seeds are small, frequently equipped with a nutritious appendage (elaiosome) that promotes dispersal by ants.

Ivy-leaved cyclamen is one of the most common and ornamental species, with pink or purple flowers and very beautiful notched leaves resembling ivy foliage. The shape of the flower is distinguished by small showy auricles (horns) at the base.

The root system is shallow, allowing it to be planted at a depth of no more than 10 cm (4 in). It grows along the Mediterranean coast from France to Turkey, where it is considered a cold-hardy species and cultivated as a park plant. In indoor conditions, it can be grown as a houseplant.

Cyclamen seeds are small, about 2-3 mm (0.08-0.12 in) long, rounded or slightly angular, light brown or brown, form in capsules, and are usually convenient for manual sowing. Germination rates typically range between 40-70%.

Before sowing, seeds can be soaked for 10-12 hours in warm water or a weak biofungicide solution with the addition of a growth stimulant: SUPERthrive, HB-101, Aminozol, Epin, or Zircon. A loose, sterile seedling substrate based on sifted peat, leaf mold, fine perlite, and a small amount of washed sand is used. Seeds are buried approximately 5 mm (0.2 in) deep, the sowing is moistened with a spray bottle, covered with a transparent lid or placed in a mini-greenhouse.

Germination is carried out in darkness or heavy shade at a temperature of 15-18 °C (59-64 °F). Crops are briefly ventilated daily, condensation is removed, and the substrate surface is kept slightly moist but not wet. Waterlogging and overheating are undesirable, as they increase the risk of rot in seeds and young tubers.

First sprouts can appear in 21-30 days, but germination in cyclamens is often prolonged and can take 6-12 weeks, with some seeds taking longer. After emergence, the crops are gradually moved to bright diffused light without direct sun. Pricking out is performed after the formation of several true leaves and a noticeable small tuber, when seedlings are convenient to handle with a small soil clump. Young plants are grown in cool conditions with moderate watering to develop a dense, healthy tuber.

Cyclamen is provided with bright diffused lighting without prolonged direct midday sun. East-facing, northeast-facing, and cool bright windows, as well as loggias without overheating, are considered most suitable. With a lack of light, leaves stretch, peduncles become weak, and flowering declines. In a hot room, the plant loses ornamental appeal faster and enters dormancy earlier.

During active growth and flowering, cool conditions at 10-15 °C (50-59 °F) are maintained. Higher temperatures are permissible briefly, but under constant heat flowers fade faster and leaves yellow more quickly. After flowering and leaf maturation, the plant gradually transitions to summer dormancy. During this period, watering is reduced, and the tuber is kept in a cool or moderately warm spot free from dampness and overheating.

Watering is carried out moderately, along the rim of the pot or by bottom watering, after slight drying of the topsoil layer. The substrate is kept slightly moist but not wet. Water getting into the center of the tuber and petiole bases is avoided, as this increases rot risk. Excess water from the drip tray must be drained after 15-20 minutes.

The soil used is loose, humus-rich, moderately fertile, and well-drained: leaf mold, a small amount of peat, fine perlite, coarse sand, and a small mineral fraction. A drainage layer is mandatory at the bottom. Shallow pots with drainage holes suited to tuber size are chosen, avoiding excess moist soil volume.

Repotting is performed infrequently, usually once every 2-3 years, after the dormant period or before active growth begins. The tuber is positioned so that the upper part remains close to the surface, without planting too deeply. Fertilizer is applied during leaf flush and flowering once every 3-4 weeks with a weak solution of flowering plant food. Excess nitrogen is undesirable because it promotes soft leaf growth and elevates tuber rot risk.

Shaping is not required. Spent flower stalks and old leaves are best gently twisted off at the base after natural wilting rather than cut, so as not to leave rotting stumps. Tuber division is rarely used because wounds take long to heal and easily rot. Sowing seeds is more reliable for obtaining young plants.
