Description of Helipterum (Acroclinum)

Acroclinium, also known as helipterum, gets its second name from the Greek words "helios," meaning "sun," and "pteron," meaning "wing." The origin of this name is still unknown, but it may refer to the shape of the pappus or leaflets, which resemble insect wings. This plant is very diverse, and some varieties actually resemble insect wings.

Acroclinums can be annual or perennial herbaceous plants. The genus contains up to 250 species. 🌱🌿

The main attraction of the acroclinium is its flowers, collected in baskets, which can be individual or gathered in inflorescences. 🌸💐 When the flowers bloom, the baskets turn toward the sun to maximize the light. Each basket contains numerous small flowers. 💫

The petals of the baskets are vibrantly colored and petal-shaped. They can be silver, white, yellow, pink, or purple. 🌺🌈

When the fruits ripen, small seeds with a ribbed surface and a feather-like tuft form. Acroclinium blooms in early summer and continues until frost, typically lasting about 30–40 days. 🌻❄️ Seeds remain viable for 2–3 years.

Sowing Helipterum for seedlings

The best time to plant helipterum seeds for seedlings is mid-April. The soil doesn't require any special preparation. You can use a special substrate for flower seedlings, which is available at gardening stores. When planting, don't bury the seeds too deeply. Simply cover them with a thin layer of soil. 🌱🏡

After sowing, it's important to water the seedlings thoroughly and cover the pots with plastic wrap. This will help create favorable conditions for seed germination. 🌱 Remove any accumulated liquid every day and open the pots for 10-15 minutes to aerate the soil. 💧 Regular misting is also important to prevent the top layer from drying out. 🌿 If you follow these rules and create comfortable conditions, the seeds will begin to germinate in two weeks, or maybe sooner. 🌱 After this, you can remove the plastic wrap and continue misting to maintain optimal humidity. 💦

Once the seedlings have a couple of true leaves, they should be transplanted into small peat pots. 🌱 In mid-May, prepare a planting site in the flowerbed and transfer the seedlings there. 🏡 It's important to remember that the older the seedlings, the more difficult and time-consuming it will be for them to adapt after transplanting due to their fragile root system. 🌿 If the top of the plant breaks off during the process, don't throw it away, as if the dried flowers take root, they will become bushier and more beautiful. 🌸

Sowing and planting helipterum in open ground

The best time to sow helipterum seeds is early May. Before planting, it's important to choose a suitable location for your plant. Make sure it's a sunny spot in your garden, as helipterum requires ample sunlight for healthy growth and vibrant blooms. Keep in mind that helipterum doesn't tolerate alkaline or overly fertile soil, so it's best not to add fertilizer before planting—it could be harmful to your plant.

Once you've chosen a suitable location, prepare the soil by making shallow furrows that are easy to place the seeds in. Then, carefully cover them with a thin layer of substrate, about 0.5 cm thick. If the weather is too dry, it's recommended to cover the plantings with a special material such as lutrosil or spunbond. If such material is not available, regular newspaper sheets will also work. 🌱🌞

After a week, you'll see the first young plants. If they're planted too close together, separate them, leaving only those 15-20 cm apart. You can transplant the separated plants to another location. To help them establish better, water the soil before transplanting and carefully dig them out with a small trowel or fork. After transplanting, water the established plants thoroughly and cover them with a shelter for a short time.

Late May is the ideal time to transplant helipterum outdoors. By this time, the soil has already warmed up, and you don't have to worry about frost. To ensure bushy, beautiful growth, leave 20-30 cm between plants. After planting, remember to water thoroughly and pinch out the top shoots to promote healthy growth. 🌱💧🌿

Caring for Helipterum

Caring for helipterum is not difficult, as this plant is unpretentious. 🌼

Watering

This plant should be watered moderately to avoid excess moisture, which can lead to root rot. 💧 The flower should be watered once a week, and less frequently during rainy season, about twice a month. 🌧️ Neglecting watering can cause the flowers to shrink. 🌺 After each watering, it is important to gently loosen the soil to ensure oxygen reaches the roots. ☁️🌱

Top dressing

💡 For feeding dried flowers, it is recommended to use fertilizer once a month. Florists recommend using complete mineral complexes, but before flowering begins. At the beginning of the growing season, nitrogen-based fertilizers are preferred, applied every 10 days. Organic fertilizers are not recommended. It is important to maintain a balance to avoid overfeeding the plant, which will lead to excessive foliage growth and insufficient flowering.

Trimming

When caring for this plant, the most important thing is to remove faded flowers from the bush. If they are left on the shoots, the blooms will quickly weaken, and new buds will not appear because all the energy will be spent on seed maturation. To avoid this, regularly trim old flowers. Ideally, this should be done once a week or even more frequently—every 3-4 days.

Care tips

Acroclinum doesn't require much care, but it's still recommended to remove weeds several times during the summer and loosen the soil before watering. This will help maintain its health and promote better growth. Covering the soil with mulch will prevent weed growth and retain moisture. Materials such as peat, compost, straw, grass, sawdust, or bark are ideal as mulch. They also help maintain looseness of the soil, which is beneficial for the plant's roots. After planting the helipterum in its permanent location, it's recommended to mulch the area and replenish the mulch periodically to maintain optimal growing conditions.

Diseases and pests of Helipterum
