Amaryllis family. Homeland - South America, mainly Peru and Ecuador. 10 species and one hybrid are widespread in nature. You will not find Ismene species in Russia, but the hybrid is of interest to us. This Ismene bent Ismene x deflexa - synonymous with Ismene x festalis or earlier Hymenocallis x festalis Hymenokallis festive (early). It is Ismene bent that is most common as an indoor, greenhouse and garden plant.

It was obtained by crossing Ismene long-petaled Ismene longipetala and Ismene narcissiflora Ismene daffodil.

It is a deciduous perennial bulbous plant. The bulb is ovoid, on average 10-12 cm in diameter, thin light brown integumentary scales. The leaves are belt-shaped, dark green in color, 50-60 cm long and about 7-10 cm wide, form an erect false stem. It is the formation of a pseudostem that distinguishes representatives of the Ismene clan from the Hymenokallis.

Peduncle single, leafless, about 40-45 cm long, umbellate inflorescence of 3-6 flowers. The perianths form a crown at the base (the lower parts of the stamens have grown together, there is a thin membrane between them) with a diameter of about 5 cm. The crown is white, large, wide, with a fringed edge. Six petals are slightly spirally wrapped. Anthers are yellow-orange. The flowers are very fragrant. On the basis of this hybrid and other species, breeding work is underway, the Zwanenburg Zwanenburg variety has been bred, which is distinguished by a larger bush size (about 80-90 cm high) and larger flowers - the crown reaches 8-10 cm in diameter.Ismene bent is not capable of seed reproduction (flowers are sterile). Bloom from about May to June for two weeks.

Another popular hybrid that can be seen on sale Ismene hybrids 'Sulfur Queen' Ismene Sulfur Queen is an interspecific hybrid from crossing the Peruvian Ismene amancae and Ismene narcissiflora. It has a pronounced pseudostem, bush height up to 60 cm. Very effective fragrant flowers, similar to narcissus flowers: yellow (canary) petals, yellow crown on the inside, with green stripes along the bottom of the stamens. From the moment of blooming, the color of the flower brightens and by noon it becomes white, only inside the crown, yellowness remains around the green stripes of filaments. This hybrid appears in European forums and markets under the names Golden Peruvian Daffodil Golden Peruvian Narcissus and Sacred Inca Lily Sacred Lily of the Incas.

This interspecific hybrid was first described by the English botanist William Herbert in 1837 as Ismene x spofforthiae. But this name is not official, in addition, initially the interspecific hybrid did not have much effect. The Dutch floriculture company CG van Tubergen, founded in 1868 by the Van Tubergen brothers and selling bulbs and seeds (it is still doing it), began experiments on crossing Ismene species, and received several beautiful varieties, one of which is Sulfur Queen to this day conquers the world.

The difference between Ismene and Hymenokallis: the first clear sign is the presence of a pseudostem in Ismene, moreover, it becomes noticeable even in a very young plant. Hymenokallis leaves always grow as a rosette. In addition, there are other differences that can be found at the time of flowering: in Ismene, the bases of the staminate filaments inside the calyx are always painted greenish, in the species Hymenokallis never. In Ismene, the flowers in the inflorescence look to the sides and even down (Ismene hawkesii), i.e. pedicels deviated from the peduncle axis horizontally. In Hymenokallis, the flowers in the inflorescence are directed upwards, i.e. pedicels in a bundle:

Temperature

During the growing season, the optimum temperature is 20-22 ° C, Ismene does not like heat, therefore, it is better to shade flowering bushes at temperatures above 26-28 ° C. During the dormant period, Ismene bulbs are stored at 12-14 ° C (not lower than 10 ° C), dry, in the same pots that they were grown. It is permissible to dig up the bulbs and store in smaller pots or boxes in sawdust, but at the same time, you cannot touch the roots (cut or break off). Storage at a higher temperature disrupts the dormant period and the bulbs may begin to germinate ahead of time. In March, Ismene can be transplanted into fresh soil, trying not to injure the roots. Watering can be resumed 2-3 days after transplanting.

If Ismene is planned to be grown as a garden plant, then at the end of March the bulbs are moved to warmer conditions - optimally 18-20 ° C (not higher), and left until they leave dormancy on their own. They are planted in the ground in early May, mixing well-rotted compost into the ground. It is impossible to water the onion itself, if the soil is too dry, then before planting you need to thoroughly shed the hole, then add a layer of dry sand or sawdust and plant, sprinkling with dry earth 2-3 cm above the bulb. After flowering, the peduncle must be cut off. And from the second half of September, if the bulb has grown, even before the onset of frost, Ismene can be dug up for storage, even if the leaves have not begun to turn yellow. If the onion has not grown enough, you can wait until the first frost. Dig up carefully so as not to damage the succulent roots.Do not break off the children formed over the summer with Ismene (we postpone reproduction for the spring). Shake off the soil, how much will fall off by itself (do not shake much). Put on its side to dry on a wire rack or mesh - the earth will dry out from the roots and crumble. The leaves begin to turn yellow and dry out on their own. In about two weeks, the bulbs are ready for storage - dry leaves can be cut off.

Lighting

Ismene are very light-loving, they need a sunny place with a southern orientation, but at the same time, light shading is needed in the hottest hours. It is better to cover the windows with a mosquito net from about 12 to 15 hours. It is very hard for Ismena, not just from the scorching sun, but from stuffiness and heat. Therefore, do not forget to keep the windows open. If there is not enough light, the Ismene bush stretches out, the pseudostem becomes indecently long, and tilts towards the light, the leaves are like whips, pale or yellowish, the flowering is poor. If this happens, it is more humane to plant the plant in a garden, in a sunny place protected from the wind. For example, on the leeward side of fruit bushes.

Watering

Watering plentifully during the growing season - the soil should be slightly damp all the time inside the pot. Those. you need to water as soon as the top layer of the earth has dried. During the resting period, watering is very limited, depending on the storage temperature. If at a temperature of 15-17 ° C - approximately 1 time in 5-6 weeks, little by little, at a lower temperature of 8-10 degrees we do without watering.

Air humidity: Ismene resistant to dry air, does not need to be sprayed.

Fertilizer

Ismene is fed with a special fertilizer for bulbous plants, diluted at a concentration recommended by the manufacturer. Top dressing begins as soon as young leaves appear, and ends when the plant has faded. At the beginning of growth, fertilizing with organic matter, diluted in a lower concentration than for ordinary flowers, is possible. During flowering and after its end, it is impossible to feed organics, the bulbs must ripen and prepare for the next dormant period.

Transfer

Soil for growing and changing: from a mixture of 2 parts of turf, 1 part of leafy soil, 1 part of humus and 1 part of sand or vermiculite. The acidity pH is close to neutral. The pots are usually large, 5-7 liters, drainage is desirable at the bottom and large holes for water drainage. When transplanting, the Ismene bulbs are buried in earth, deepening 3-5 cm.If the onion becomes bare over time, it should be mulched with fresh earth.

When planting Ismene in the garden, there are no special requirements for soils - these plants just do not like strongly alkaline and strongly acidic soils. Vigorous plants are changing, they build up green mass well and quickly with the beginning of the growing season, therefore, well-rotted compost is added to the pit during planting. But since the bulbs are very sensitive to waterlogging, the soil must be very airy. To do this, you can add sand, vermiculite, bark, straw, whatever you like to the soil, so long as a dense layer of earth does not form after rains.

Reproduction

Ismene is propagated by daughter bulbs during transplantation. Ismene bent baby grows well, sometimes to the detriment of flowering, does not reproduce by seeds. It has been noticed that bulbs located close to the surface of the earth are more prone to budding, so sometimes it is advisable to bury the bulbs deeper, but monitor the condition of the soil - it should not be waterlogged. Onions rot from high soil moisture.

Diseases and pests

Ismene can infect aphids, thrips, whitefly, they do not disdain this plant, especially in indoor conditions, scale insects and whiteflies. There is only one measure against all pests: removal of colonies, larvae and pest secretions with an alcohol solution using a cotton swab, watering with aktar or confidor.

Ismene bulbs, like any others, can be damaged by rot from excess moisture in the soil, if the weather is too rainy, when frequent watering or heavy clay soil.
