Types and varieties of Ammobium

Ammobium is a small genus, comprising only three natural species. However, many original cultivars have been developed from these, enjoying great popularity among gardeners and plant enthusiasts. 🌿✨

Ammobium alatum

It gets its name from the distinctive wing-like shape of its leaves. 🍃 The stems of this herbaceous shrub can grow up to 0.7 meters in height, are straight and branched, and their surface is covered with downy hairs. The leaves are elongated with pointed tips.

In summer, basket-shaped inflorescences 🌸 appear at the ends of the stems, consisting of small tubular flowers surrounded by scales, giving them a petal-like shape.

There are various cultivars of this species, varying in flower size and stem height. Some have larger flowers and shorter stems (approximately 40 cm), while others retain similar flower and leaf sizes. 🌼

Variety	Description
Large-flowered	It is distinguished by tall shoots, reaching 72 cm or more. The flowers are large, with a diameter of 1.9 to 2 cm. This variety is grown from seedlings.
Bikini	Characterized by its compact size, the shoots do not exceed 40 cm. The flowers of this variety are uniform in size and shape. Cultivation is also carried out using seedlings.

Ammobium craspedioides

Also known as the Yassian daisy, this perennial forms rosettes with simple, single-headed stems. 🌼 The surface of their stems may be covered with hairs. The basal leaves have a variety of shapes, from oblong to lanceolate, and sometimes spoon-shaped. 🍃 The leaves range in length from 3 to 12 cm, and in width from 10 to 17 mm, with an acute apex. The upper surface of the foliage is covered with scale-like hairs, and the underside is woolly. The petiole is winged, ranging from 10 to 30 mm in length.

The stems rarely bear leaves, and these may be edged with narrow "wings." The rosettes die after flowering. The leaves on the stems are few and tiny. 🌿

The spring flower heads of this species are hemispherical, button-like inflorescences up to 10–20 mm wide. They are surrounded by papery, leaf-like bracts. The solitary flower heads on unbranched stems reach a height of 30 to 60 cm. The inflorescences are straw-colored, with bright yellow tubular flowers inside.

After flowering, the plant produces seeds that are 4 mm long. Their surface is smooth and pale brown, with a calyx ranging from 1 to 1.5 mm in length, and awns that can reach up to 1.5 mm in length or are absent. 🌾

Ammobium calyceroides

A fairly rare species, distinguished by its short stems, never exceeding 20 cm. 🌿 In the wild, it is found in the alpine and subalpine meadows of New South Wales. The shoots of this plant are thick, pubescent on the surface, and have a greenish tint, sometimes turning reddish toward the tip. The leaves form rosettes at the base. The leaves are a rich green color, oblong, ovate-elongated, and pointed at the tips. 🍃 They may have hairs on their surface, or the foliage may be bare.

In summer, capitate inflorescences appear on unbranched flower stalks arising from the center of the rosette. They consist of numerous small whitish flowers. Each flower has a tubular corolla that opens into five lobes with pointed ends. Stamens with yellow anthers emerge from the flower. 🌼

Features of sowing and growing ammoubium seedlings

In southern regions with warm winters, ammoubium seeds are sown directly into flowerbeds, either in the fall or spring. However, in more northern latitudes, it is preferable to grow seedlings.

You should start growing seedlings in March or April. Fill the seedling trays with a special seedling substrate or a mixture of equal parts sand and peat. Since the seeds are very small, it is recommended to pre-mix them with sand to ensure even distribution over the soil surface. Then lightly dust them with a thin layer of the same substrate. Gently spray with warm water from a fine-mist spray bottle to prevent the seeds from being washed out of the soil.

Place the seed trays on a well-lit windowsill, but protect them from direct midday sunlight. You can cover them with a piece of glass or transparent film. Maintain soil moisture by regularly misting with warm water and ventilate the trays.

In a week or ten, you can expect the first shoots to appear. Once the ammoubium seedlings have two true leaves, they can be transplanted into individual pots or returned to their seedling trays, leaving approximately 7 cm between plants. It's preferable to use compressed peat pots for transplanting to avoid damaging the roots when subsequently transplanting them outdoors.

Transplant the ammoubium outdoors after the last frost, around the end of May. When planting, provide the plants with ample water and fertilizer to ensure successful establishment. 🌼

Rules for caring for ammoubium

To successfully grow ammobium, it's important to follow certain care guidelines, including choosing the right location, the right soil, watering, fertilizing, and pest control. In this guide, we'll cover the basic steps for caring for ammobium, helping to ensure healthy growth and beautiful blooms.

Location

When planting dried flowers, it's important to choose a well-lit location, so it's best to choose a flowerbed in an open area protected from drafts. Avoid locations where water can accumulate after rain, as the ammoubium can rot due to over-watered soil. If the soil is too wet, you can create a raised bed for growing this plant.

Priming

Ammobium, also known as "immortelle," prefers dry, well-drained soil. 🌱 It thrives in sandy soil with few nutrients. However, it can generally grow in soil with a slight clay content. 🏜️ Avoid overly wet or clayey soils, as this can cause root rot. 🚱 Good drainage can be ensured by adding coarse sand or fine expanded clay. ⚒️ The optimal soil pH is approximately 5.5–6.5, which provides conditions for the healthy growth of Ammobium. 📏 Before planting, it is necessary to thoroughly prepare the soil by removing root debris from other plants and digging it. 🌱

Watering

After planting, ammoubium requires moderate watering to help the bushes adapt. 💧 After this, the plant is usually quite drought-resistant and receives sufficient moisture from natural precipitation. 🌧️ Additional watering is only necessary in cases of severe and prolonged drought. 💦 The general rule for watering ammoubium is moderation. 🌱

Top dressing

For Ammobium, it is recommended to apply fertilizer one week after planting outdoors. 🌱 Nitrogen fertilizers, such as nitroammophoska, are suitable for stimulating foliage growth. 💧 It is important not to overdo it with nitrogen, so as not to suppress flowering and stimulate excessive foliage growth. 🌿 After another two weeks, you can switch to using complete mineral complexes, such as Fertika, Agricola, or Kemira-Universal, to feed the mature bushes. 🌼 Mullein infusion also has a positive effect on Ammobium growth. 🐄 Fertilizer should be applied only once during the growing season. 🌿

Rules for planting ammoubium

Planting Ammobium at the end of May is ideal, especially if using seedlings. 🌱 The planting hole should be a suitable size to accommodate the seedling and ensure the root collar is level with the soil. 🕳️ If the seedlings were grown without containers, they should be watered thoroughly before planting. 💧 It is best to remove the plants from the seedling tray with a tablespoon to maintain the soil ball around the roots. 🥄 The distance between seedlings should be approximately 30–35 cm. 📏 Before placing the plant in the hole, add drainage material and soil. 🌱 After planting, water thoroughly. 💦 If you are creating a raised bed, you can create it using the mounding method using a drainage layer and suitable materials. 🏞️ This will create optimal conditions for Ammobium growth, even if the soil is not ideal. 🌱 After preparing the bed and planting the plants, give it a few days to settle, and then you can do additional planting, if necessary. 🌿

Potential problems when growing ammoubium

Ammobium delights gardeners with its pest resistance, but improper watering can lead to rot. 🌿 If care instructions are not followed, a whitish or grayish coating may appear on the plant, and the leaves will begin to turn yellow and fall off. 🍂 To combat rot, remove the affected parts of the plant and treat it with fungicides, such as Fundazol or Topaz. 💧 After this, replant the bushes and adjust the watering schedule. 💦

Using Ammobium in Landscape

In the gardening world, ammobium may not command the same attention as exquisite roses or fragrant peonies. However, its presence can liven up the atmosphere in rock gardens and alpine gardens. 🌿 Plants of this species can complement each other beautifully, creating unique compositions. Ammobium is also suitable for dried bouquets, retaining its freshness and beauty for many years. 🌼

Harvesting ammobium

For dried arrangements with Ammobium, it's best to select buds just beginning to open. At this point, the flowers are not yet fully open, and the tubular flowers are protected by marginal scales. When collecting Ammobium stems, choose those that are approximately 25 cm long. Bundles of stems are hung in an attic or other dry, well-ventilated area, with the flower heads facing downwards and protected from direct sunlight.

However, it's worth remembering that after drying, the bright yellow color of the flowers darkens, so to preserve the attractiveness of the inflorescences, you can perform a belinia procedure. This involves treating the ammobium stems with sulfur vapor in an airtight box, where hot coals and sulfur powder create a special atmosphere. After this procedure, the inflorescences acquire a glossy white color around the edges with a bright yellow center. 💨

These dried ammobium flower "bouquets" can be used to create phyto-arrangements that will delight the eye for a long time and add a cozy touch to your home or office. By combining them with other plants, such as eryngiums, physalis, or helichrysum, you can create beautiful arrangements that will retain their beauty for a long time. 🌼
