Dangerous but Beautiful Dictamnus, or Ashen
Known under the popular nickname "burning bush", ash-tree, or dictamnus, is a herbaceous perennial from the category requiring careful handling. It leaves burns on the skin, is able to flash in a matter of seconds, is toxic, which imposes significant restrictions on the possibility of use. But those who replenish their garden ensembles with at least one dictamnus bush will never abandon the luxurious flowering of this dangerous handsome. After all, a little caution is not such a big price for amazing tenderness and ease of cultivation.
Unhappy perennial character
Ash tree is able to create spectacular thickets. How these plants just do not call! And wild ankles, and ash trees, and an indelible bush. And every nickname culture has earned for unique talents. In the hot heat, if you bring fire to the plant, it will break out in a bright flame. Yes, and on the skin leaves almost the same burns as the flame. Many associate with the dictamnus the biblical legend of the burning bush. And given the ease of ignition of dictamnus, the assumptions about the possibility of its self-ignition under the rays of the desert sun are quite logical. But you shouldn’t be afraid of the fire: the thing is volatile essential oils, which are flammable and quickly go out without harming the plant itself or its neighbors.
Fraxinella (Dictamnus) Is a small genus of decorative Eurasian perennials. Rhizome and large, upright, up to 1 m in height, they look most attractive during flowering, but their greens are very good.
In the genus of dictamnus, 6 plants were previously isolated. But they are all so similar to each other that modern scientists have found the perfect compromise and combined individual forms into one kind - dictamnus white (dictamnus albus) Plants formerly known as Caucasian ash-tree (dictamnus caucasicus), as well as less popular fluffy (dictamnus dasycarpum), holobolbikovy (dictamnus gymnostylis) narrow-leaved (dictamnus angustifolius) dictamnus today are not even classified as plant forms (all old names are synonyms for white dictamnus).
Dittany (dictamnus albus) - the most famous representative of the genus, and according to scientists, also the only one. This is a spectacular tall perennial growing up to 1 m (during flowering). It has a branched, powerful rhizome and straight shoots covered with a thick edge. They are beautifully in harmony with whole basal and unpaired stalk leaves, sitting on long petioles. Greens reminds an ash-tree in the form, forms magnificent curtains, dense, with a cold-gray color. On flower beds, especially at the height of summer, ash trees look fresh, as if they had just been watered. The serrated edge, glandular fringe and dense texture of the leaves are as if specially created by nature in order to unfold the delicate flowering.
Flowers up to 2.5 cm in diameter with 6 pointed petals are white or pinkish, stamens are yellow-green, sometimes colored, elegant. Inflorescences-brushes up to 20 cm long seem lacy, sparse, but very elegant and large. The flowers in them are clearly visible, perceived as massive, veins more typical for leaves are visible on the petals. The color is complex, as a rule, the veins are contrasting, and large stamens only add to the asymmetric flower of grace. The undoubted advantages of dicmanthus include aroma: this plant is very fragrant, and during flowering it is easy to recognize even from a distance. True, the scent of ash, reminiscent of something like dry orange peel, not everyone likes. After flowering, capsules are formed that hide the black shiny seeds.
White ash has separate garden forms - pink and dark red. The color scheme of dictamnuses is generally limited, but not at all uninteresting. An ash tree produces either white or pink flowers, and pink colors are always surprisingly complex. Against the background of light petals, dark pink veins appear brightly, making the whole plant seem graphic and watercolor at the same time. We, under the guise of a separate plant, often continue to sell Caucasian ash-tree - a smaller pink-flowered and elegant dictamnus. The best of the white-flowered varieties “Albiflorus” seems to be a grassy relative of magnolias, very elegant and gentle.
Dictamnus blooms in June and July, flowering is long and equally effective for almost a month and a half.
Ashman requires a special approach
The main characteristic of dictamnus is its aggressiveness. This is a super-toxic beauty, contact with which leaves severe burns and wounds on the skin. Moreover, the effect of toxins is not felt immediately. Work with dictamnus, its landing and trimming require extreme caution and complete protection of exposed areas of the skin of the hands. Close leaning toward the plant, inhaling the aroma of flowers is also not worth it (chemical burn of mucous membranes is no less dangerous than epidermal). But the myths that it is impossible to approach the plant are not justified: firstly, the plant leaves serious burns only in sunny weather, and secondly, let the healing of irritations take time, they are not irreversible. Like any toxic or poisonous plant, ash tree just requires a neat approach and candor.
But dictamnus will pleasantly surprise not only with beauty, but also with durability, they do not require a transplant for a decade. And if you give them enough space so that there is no need to restrain the plant and limit its distribution, ash can be completely planted and almost forgotten.
Ash-tree in decorative gardening is used;
- as a visual peak, the highest emphasis on flower beds and flower beds;
- as a background culture on flower beds and to fill the middle plan of bilateral rabatok;
- single bushes as decoration of "flat" flower beds and small groups in the role of high flowering decoration of texture flower beds;
- as one of the most catchy country style plants;
- in romantic ensembles with a focus on the original flowering and pink palette;
- in landscape groups and massifs;
- in the design of rockeries and rock gardens;
- in mixborders with flowering relay.
On flower beds and in decorative compositions, dictamnuses should be placed away from the tracks so that they are not in the “contact zone”. You need to be careful when placing ash in mixborders or in recreation areas: despite the aroma and beauty, the plant is too toxic for carefree placement.
Best partners for dictamnus: heicher, monard, kermek, daylilies, lyatris, gypsophila
One of the main advantages of ash-tree - a place for this plant can be found in every garden. After all, dictamnus grows well in the bright sun, even on the southern sides of rock gardens and rockeries, and in secluded partial shade. True, strong shading is better to avoid (it negatively affects flowering), but the ash tree practically does not notice light partial shade.
In order for the ash-tree to reveal all its decorative talents, it needs to be provided with alkaline or at least slightly calcareous soils. Even on neutral ground, the Sentsi bloom weaker. But the other characteristics of the soil should be paid attention to: dictamnus likes gravel and sand, light, rocky soils, loose and loose. This plant feels great in rocky gardens and is not too demanding on soil nutrition (but on medium-fertile soil it grows better than on poor soil). Ash-tree does not tolerate moist and swampy soils.
This plant can be planted only on cloudy, non-hot days, exclusively in early spring or September. Diktamnus seedlings respond better to transplants, but it is better to transfer them to a permanent place in a favorable period. Delenki, transferred in the heat, die: in the summer, any transplant is unacceptable.
Since the ash tree itself is actively growing, it can not be planted too close to neighboring plants. The optimal distance is about 50 cm. Dictamnuses are planted in the simplest planting pits, maintaining the same level of penetration. After planting, the plant needs to be provided with abundant watering and systematic procedures should be made until there are signs of growth (but excessive dampness should not be allowed).
Ash tree is more than an easy-to-care plant. Thanks to drought tolerance and endurance, it is content with really minimal maintenance. Watering for the plant is carried out only in a too prolonged drought during the flowering period, when extreme dry soil can stop flowering earlier.
Feeding dictamnus as such is not necessary, but it is better to maintain at least a light soil nutrient and its alkaline characteristics. For this purpose, it is enough to introduce a standard dose of alkalizing universal fertilizers once a year, in early spring (start with the 3rd year on good soil and the second on depleted).
Otherwise, caring for ash trees comes down to ordinary procedures - weeding weeds on flower beds and periodically loosening the soil after heavy rainfall. If dictamnuses grow in landscape groups, in large massifs, in rockeries or rock gardens, then they will not need such care. But on flower beds and flower beds you can save yourself from unnecessary worries by simply mulching the soil.
Dictamnuses need pruning, but when to carry it out - you choose. If you want dry shoots and open seeds of ash to decorate your garden under hats of snow, leave pruning in early spring. And those who do not want to add to themselves the hassle of the most active season of gardening can cut dictamnus at the end of the year, in late autumn.
Wintering of an ash-tree
Dictamnus are completely winter-hardy plants that are not afraid of even the most unexpected changes in winter temperature and do not need any special preparation for the coldest time of the year.
Pest and Disease Control
In garden culture, as in nature, ash is practically not sick. The only thing that threatens the plant is an improper planting.
Dictamus breeding methods
Dictamnus is a very easy-to-breed culture. It is so actively distributed by self-seeding and growing that new copies can be obtained annually.
Propagation of lamb by seeds
Seeds, preferably freshly picked. To prevent seeds from spilling, you need to constantly monitor the plant in August, because they crack literally in a matter of days. For this crop, sowing immediately after harvesting directly into open soil is more suitable. There are alternative methods - sowing in the winter or in the middle of spring, but part of the seeds can germinate only after a year. Dictamnus is sown in seedlings, and not in a permanent place. Seedlings that appear in the spring break out, leaving 15 cm between the plants and grow them with at least rare watering for 2-3 years (dictamnus will bloom only 3-4 years after sowing, so you should not rush to transfer it to a permanent place).
Propagation of ash by dividing the bush
For this method, it is critical to comply with the deadlines: if you divide the ash bushes in the summer or in hot weather, you will not be able to save parts of the plant. Therefore, the procedure for separating curtains should be carried out not only reliably protecting hands with gloves, but also strictly adhering to the favorable period: in the early spring to the third decade of May or in autumn, exclusively in September. In order for rootlets to take root, they must be large, and in a new place the plants will have to provide abundant watering.
Propagation of lamb by cuttings
Non-lignified, young shoots are easily rooted in ash, provided that they are treated with growth accelerators after cutting. You can root cuttings under caps in boxes or pots, and in the soil in greenhouses.
