Light Requirements
Helichrysum lentii Volkens & O.Hoffm. typically requires full sunlight exposure to grow and thrive properly. This plant prefers at least 6 hours of sunlight per day. Lack of adequate sunlight may result in stunted growth, weak stems, and fewer flowers.
Temperature Conditions
These plants are well adapted to hot and dry climates. They grow best in a temperature range of 25-30°C (77-86°F) and can tolerate temperatures as high as 40°C (104°F). Helichrysum lentii Volkens & O.Hoffm. is not frost tolerant and cannot withstand extreme cold temperatures.
Soil Requirements
The ideal soil for Helichrysum lentii Volkens & O.Hoffm. is well-draining, sandy, and rich in organic matter. This plant thrives in slightly acidic to neutral soils, with a pH level of 5.5 to 7.5. This plant can grow in poor soil but may require regular fertilization to maintain its growth and health.
Cultivation methods
Helichrysum lentii, also known as the immortelle plant, is native to the island of Crete. It prefers a warm, dry climate and well-drained, slightly alkaline soil. When growing immortelle, it's important to choose a location with full sun exposure, preferably on a slope to allow for improved drainage.
The seeds should be sown in early spring, spaced out at least 8 inches apart in the soil. The soil should be kept moist until the seeds germinate, which usually takes around two weeks. Once the plants have grown to around 2 inches in height, they can be transplanted into their permanent location, with at least 18 inches between each plant.
Watering needs
The immortelle plant is drought-tolerant and prefers to be watered infrequently but deeply. Watering once a week is usually sufficient, but it's important to ensure that the soil doesn't become waterlogged. Aim to water the base of the plant rather than the leaves, as this can encourage the growth of mildew and other diseases.
Fertilization
Helichrysum lentii doesn't require a lot of fertilization. In fact, applying too much fertilizer can actually harm the plant. It's best to avoid using chemical fertilizers, as these can affect the taste and scent of the plant. Instead, add some compost or slow-release organic fertilizer to the soil in early spring before planting.
Pruning
Pruning the immortelle plant is not essential but can help to encourage more bushy growth. It's best to prune the plant in the early spring before new growth appears. Cut back around one-third of the plant, taking care not to cut too close to the woody stems. Deadheading spent flowers regularly can also help to prolong the blooming period of the plant.
Propagation of Helichrysum lentii Volkens & O.Hoffm.
Helichrysum lentii Volkens & O.Hoffm. is propagated through both sexual and asexual means.
Propagation by Seeds
Seeds can be collected from the plant when the flowers have dried on the stem. The seeds should be air-dried and stored in a cool, dry place until planting. When planting, the seeds can be sown directly into the soil or started indoors. The soil should be well-draining, and the seeds should be pressed lightly into the soil. Germination should occur within two to three weeks, and the seedlings can be transplanted after they have established several leaves.
Propagation by Cuttings
Helichrysum lentii Volkens & O.Hoffm. can also be propagated by cuttings. Cuttings should be taken from a healthy and established plant during its active growth phase. The cuttings should be taken from the tips of the stem and should be at least 8-10 cm long. Remove the lower leaves and insert the cuttings into a well-draining soil mix. Water the cuttings thoroughly and cover them with a clear plastic bag to create a humid environment. The cuttings should be kept in a warm and bright location but out of direct sunlight. Rooting should occur within 2-3 weeks, and the new plants can be transplanted after they have established roots.

Common Pests
Helichrysum lentii is also susceptible to various pests, such as aphids, spider mites, and whiteflies. These pests feed on the sap of the plant and weaken it, leading to stunted growth, wilting, and deformation of leaves and flowers. These pests can also spread diseases from one plant to another.
Pest Management
Regular monitoring of the plant and early detection of pest infestations can help prevent their spread. Pest control methods can range from natural remedies, such as spraying the plant with a mixture of soap and water or neem oil, to chemical insecticides. However, it is important to use these methods only as a last resort, and to follow the instructions carefully to avoid harming beneficial insects, animals, and the environment.
