Such an ornamental deciduous plant like arundinaria (Arundinária) is a perennial and is directly related to the cereal family. This plant comes from Japan and China, but at present it can be found in natural conditions in Western Europe and the United States. It is also called reed or indoor bamboo. This genus unites 20 different species. Some of them are very popular with florists and gardeners. Depending on the species, the height of the arundinaria can vary from 0.5 to 8 meters. At home, as a rule, only dwarf species are grown, the height of which varies from 0.4 to 3 meters.
Such a plant has hard, belt-shaped leaves that adjoin the base of the shoot. In the process of growth, such leaf plates gradually bend away from the shoot and become drooping. These leaves are not very large in size, and they also have a petiole. On their surface there is a clearly visible pattern of veins. The color of shoots and foliage directly depends on the species, and can be of any shade from silver to purple, dark green or cream. Drooping or creeping (with nodes and internodes) shoots that form a bush or thickets grow directly from the rhizome. The inner part of the stems is hollow, and the shoot itself is tree-like to the touch. Due to these characteristics, the stems are widely used in the creation of toys, as well as hedges.
A brush-shaped inflorescence (paniculate) bears small flowers. Spikelets are long, loose, one-flowered.
Arundinaria is a tropical plant, in this regard, he needs to try to create conditions close to natural. The greatest difficulty for flower growers in caring for such a plant is the correct wintering, since the required temperature should be at around 6-8 degrees.
The optimum temperature in summer is from 18 to 20 degrees, and in winter - about 10 degrees (preferably from 6 to 8 degrees). At a high (more than 15 degrees) room temperature in winter, such a plant begins to grow worse. Wintering in warmth depletes arundinaria, which can lead to its death. In the summer, experts advise moving the plant outside. It is also necessary to systematically ventilate the room where it is located.
Under natural conditions, such a plant prefers to grow on lake and river banks, in marshy lowlands. But despite this, in room conditions, it does not need high humidity. Experienced growers recommend that the need for air humidity in arundinaria should be determined empirically. So, if at low humidity it grows and develops normally, then humidification with a sprayer can rarely be carried out. If the air humidity is too low, then you need to spray the foliage every day. Only soft water is suitable for this purpose.
In the spring and summer, you need to water 2 or 3 times every 7 days. The soil in the pot should be moist at all times. The earth ball should never dry out completely. In winter, watering is severely limited. So, at this time, it is recommended to water the plant only after the top layer of the substrate has thoroughly dried.
Top dressing is carried out systematically 1 or 2 times a month. For this, mineral fertilizers are used. To improve the growth and development of young specimens, phosphorus-containing fertilizers are used, and nitrogen-containing fertilizers are used to increase the amount of foliage. An adult specimen needs rather rare dressings, which are produced only if the plant has signs of nutritional deficiency. In autumn and winter, fertilizers are not applied to the soil.
Important! Such a plant blooms only once and this, as a rule, occurs at 33 years of age. After flowering ends, the bush dies.
Such a plant should be protected from direct sunlight. It grows best in diffused lighting or partial shade. In this regard, it is recommended to place it on a north or east orientation window. If you put it on the west or south window, you will need shading from the scorching midday sun rays.
Arundinaria feels best in a room of western and eastern orientation. It can also be placed in a southern room, but it should be cool. She will feel great in the greenhouse, on the veranda or in the foyer of the institution.
You can buy commercial potting soil for palm trees, for dracaena, or for dracaena and yucca. The most suitable soil should have a pH of 6.8. To prepare the soil mixture, it is necessary to combine in equal parts compost and clay-turf soil, as well as sand. It is recommended to add a little leafy earth.
It can be propagated by dividing the rhizome, while this procedure is recommended to be carried out during the transplantation process. You can also root cuttings that are obtained by pruning a bush. However, remember that pruning is not necessary.
Cutting of green cuttings is done in summer or spring. They are planted in the soil, while it is necessary to provide the bottom heating of the container. These cuttings need warmth and high humidity.
The rhizome freed from the soil should be divided with a sharp knife into the required number of divisions. After that, each piece is planted in a separate container filled with a moistened earth mixture. Cover the stalk with a transparent bag and place in a well-lit and warm place. You need to remove the shelter after 2 or 3 days.
The plant is transplanted in the spring, as a rule, once every 2 or 3 years. You can transplant only when necessary, for example, when the roots fill the entire container. It is recommended to transplant the flower by the transshipment method without disturbing the earthen lump. A wide and not too high pot is suitable for planting.
Basic tips for grooming:
Interesting! In the United States, the east coast has become a site of widespread distribution of such a plant, which greatly worries local residents.
The main problems with growing:
Whiteflies and spider mites can settle on foliage.
This species has become known only recently. In nature, such a plant can be found in North America in the Appalachian Mountains. It is also called mountain reed. The bush is usually not very tall, but rather bushy. It is often used as a ground cover plant. Grows best in partial shade of large garden plants. It grows very rarely at home.
This plant comes from China. It has a very effective appearance, but it is more popular with gardeners than with florists. Under natural conditions, it reaches a height of 10 m, and when grown in a house - from 80 to 100 centimeters. Shiny, smooth, belt-like leaves are rather tough to the touch. When grown outdoors, a whitish bloom or randomly located spots of a silvery color appears on the surface of the foliage. This plant branches quite strongly, due to which it forms a very lush bush, which looks extremely impressive. Young shoots of such arundinaria also have a very attractive appearance due to their reddish-brown color.
Such a plant is a perennial. Its rhizome goes quite deep into the soil. Shoots can reach a height of 6 m. On the surface of the shoots there is a coating of wax. They are cylindrical, straight and have protruding nodes. The plant branches quite strongly. Quite large leaf plates, painted in dark green, have a lanceolate or lanceolate shape. Inflorescences have racemose or panicle shape and consist of single-flowered, long and rather loose ears.
The shoots are purple-green. The leaf plates reach 18 centimeters in length, and stripes of yellow color flaunt on their surface. Has a height of about 150 centimeters.
Narrow leaves can be up to 10 centimeters long. The shoots are colored purple. The height of the shoots can be up to 300 centimeters.
This species is most suitable for indoor cultivation. The leaves can be up to 100 centimeters long, and they have a very effective appearance.
This species is similar to the brilliant arundinaria, but this plant has yellow shoots.
Homeland are the southeastern regions of the United States. The diameter of the stems in natural conditions is 7 cm, while they can reach 10 m in height. Young shoots are slightly lignified, but as they grow, they become completely lignified. Cylindrical shoots are hollow inside. The plant is highly branched, due to which it is able to form dense thickets. The length of the leaf plates varies from 10 to 30 centimeters, and the width is from 2.5 to 4 centimeters. They have a rounded base and pointed tips. This species is frost-resistant, it is not afraid of temperature drops to minus 30 degrees, while the leaves do not fall off in winter.
Interestingly, with age, the stems are completely lignified and become similar to bamboo.
Primroses bloom in early spring, being one of the most beautiful harbingers of this time of year. However, this only applies to some species. Many species bloom in summer. How to grow a perennial primrose - planting and care, photos of the species are presented in this article.
Cultivating wild species is not an easy task, and it takes a lot of time for a plant to get the necessary traits. Despite the fact that the genus lanthanum has many species, few were suitable for breeding. One of these species is spiny lantana. Also, this type of perennial shrub, reaching a height of one and a half meter in nature, is called vaulted lantana or camara (Lantana camara). Thorny lantana got its name not by accident: its erect shoots with a lignified top layer are completely covered with small thorns. The foliage is colored deep green. The leaf plate with small denticles along the edge has an ovoid shape, in which the outer tip is slightly pointed. The front side of the plate is rough to the touch, and the inner side, hidden from the eyes, is covered with soft whitish "villi".
The plant is characterized by a paniculate type of inflorescence. The diameter of the corolla in flowers is no more than 5 cm. During the flowering period, which lasts from May to October, the plant forms beautiful lush "balls" of flowers of different colors. At first, buds appear with yellow or pink petals, and only over time, the color of the petals changes to orange, and then to red. The ripe berries formed after the petals fall off have a blue-black color.
The cultivar "Lyubava" is created on the basis of vaulted lantana. Its main characteristics are not much different from its progenitor. Green stems strewn with thorns, faceted on 4 sides, oval leaves with a greenish-gray tint, and medium-sized flowers that form inflorescences-balls. During the flowering period, the color of the petals changes from orange to pink or scarlet. Some breeders have bred hybrids with monochrome inflorescences. For the variety "Samantha" the character is lemon-yellow color of the inflorescences, and for the hybrid "Golden Apple" the flowers have a bright golden hue. White color of flowers with a slight accent in the form of a small yellow speck in the center is characteristic of the variety with the beautiful name "Naida".
Montevidean lantana (Lantana montevidensis) is somewhat different from Camara. The stems of this species are flexible and curly, and the lignification of the upper layer is observed only closer to the base. Ovate leaf plates are slightly smaller than those of the prickly species of lantana, their length does not exceed 3 cm. The flowers are smaller in comparison with the camara, the corolla diameter is within 2–3 cm, collected in spherical inflorescences, in which purple lilac and pink tones. Flowers with yellow or white color are much less common.
Variegated lantana (Lantana variegata), in contrast to the previous species, has a slightly different leaf color. Its leaf plates are variegated: pale green, whitish and silvery specks are scattered in a chaotic manner over the entire surface. To obtain such changes in the color of foliage, plants of this species undergo artificial modifications, which almost always affects the resistance of the species, which means that the resulting hybrids will be more demanding in care.
According to the structure of the flower, Phalaenopsis are divided into two groups.
Group I, Euphabenopsis, characterized by whisker-shaped processes on the lip and petals wider than sepals.
IGroup I, Stauroglottis, has petals similar to sepals and a lip without processes. In both groups, a variably shaped lip connects to a widened column base called the “leg” of the column.
Below are photos, names and descriptions of Phalaenopsis orchid varieties of both groups.
Group I, Euphalаenopsis. The lip of plants of this group has two processes either in the form of tendrils or in the form of thin horns. The petals are wider than the sepals and are compressed at their base into thin "claws".
Phalaenopsis amabilis – Phalaenopsis amabilis... One of the most popular species of the genus, together with Phal. aphrodite is the basis of most modern white hybrids. Leaves are pure green, 10-30 cm long.
Pay attention to the photo - in Phalaenopsis orchids of this species, long curved peduncles bear many flowers, each from seven to twenty in diameter:
The pure white petals and sepals contrast with the lip, which is highlighted in yellow, with red spots and stripes, and bears a pair of wavy tendrils falling from the outer end. If the peduncle is cut just below the node that gave the first flower, it releases secondary peduncles. The plant is found in Java, Borneo, Ambeina and the Philippines and blooms in autumn and early winter. There is a form with large, well-formed flowers - var. rimestadiana, as well as a form with pinkish or dark pink flowers - var. sanderiana. The two famous plants provided the basis for a hybrid line that leads to modern hybrids.
Phalaenopsis Aphrodite – Phalaenopsis aphrodite... White, sometimes with a pink blush, flowers similar to Phal.amabilis, but smaller and collected in flowing clusters. In the Phalaenopsis orchid of this variety, the lip is colored pink and yellow and has two thin, twisted antennae. Leaves are brownish green, with veins in the center, about 30 cm long. Grows in Java, Philippines. It blooms in spring and summer.
Phalaenopsis pulcherima – Phalaenopsis pulcherrima... This species is somewhat different from other members of the genus. It has its own history, for a long time it was considered a separate genus, like Doritis pulcherrima, called Phal. esmeralda. It has pointed leaves 20–25 cm long. The slender, tall peduncle bears many flowers with a diameter of 2.5–3 cm. Sepals and petals range from white to amethyst. The lateral lobes of the lip vary in color, from purple to orange to brownish-red, the middle lobe is purple, pointed. Two antennae appear behind the crest at the base of the middle lobe of the lip. This species grows in Cochin (China).
Phalaenopsis pink – Phalaenopsis equestris (Ph. Rosea)... Homeland - the Philippines, where this is the most common species of the genus grows in the valleys along the river banks. One of the miniature species of the genus. Leaves are oval or oblong, 10-15 cm long, 7-8 cm wide, dark green, sometimes reddish below. Gracefully curved, dark purple, relatively short (20-30 cm) peduncle bears 10-15 small white-pink flowers about 3 cm across, blooming one after the other in succession. Sepals are oblong, white, with a pale pink indistinct longitudinal stripe, petals are wider than sepals, the same color, but with an intense pink stripe. The lip is small, three-lobed: the lateral lobes are directed forward, pink at the base, white on the inner side, with 3-5 dark purple short lines; the middle lobe is rhomboid or ovoid, bright pink, with a brownish tint at the base, sometimes with a white tip. Anther with a long beak.
Phalaenopsis Stewart – Phalaenopsis stuartiana... This charming species has small, original colored flowers. Young leaves are variegated, mature - grayish-green, purple below. Sepals are white, with pale yellow sides on the inner half and with red spots at the base. Petals are white with light purple spots at the base. The golden yellow lip has a white, purple-spotted pattern and a pair of horns at the top. Flowers of this species are especially well preserved and are collected in branching clusters. Grows in the Philippines, blooms in winter. Used in hybridization.
Phalaenopsis Schiller – Phalaenopsis schilleriana... This remarkable species forms amazing drooping brushes, branching and bearing no less than a hundred pink-purple flowers. The plants have long leaves dotted with grayish-white stripes and purple underneath. The roots are flat and tough. Flowers are about three inches across. The pink tone of petals and sepals fades at the edges. The lip is the same color with red dots. Instead of antennae, there is a pair of diverging horns at its top. Grows in the Philippines, blooms in spring. This species is widely used in hybridization in order to combine its branched dense arrangement of flowers on the peduncle with a denser substance and large size of white hybrids.
Group II, Stauroglottis... The lip of plants of this group has no processes, and the petals are closer in size to the sepals. The plants are smaller than those of group I, and the flowers, although smaller, are usually brightly colored, often with beautiful stripes and spots.
Phalaenopsis decumbens – Phalaenopsis dekumbens... Long called Phalaenopsis amethystina, this species is a small plant with wavy leaves at the edges.
Look at the photo - in the Phalaenopsis orchid of this variety, cream flowers have a lip of a rich, amethyst-purple color with white stripes and a pattern:
Grows in Java and Sumatra, blooms in autumn.
Phalaenopsis Cornu Servi – Phalaenopsis cornu-cervi... Yellow-green flowers with brown stripes, white lip, loosely arranged on a peduncle whose shape resembles a deer horn. It is a naturally falling species, but does not require a dormant period in a greenhouse. It grows in Burma and Java and blooms throughout the year.
Phalaenopsis Linden – Phalaenopsis lindenii... A free blooming species with narrow speckled leaves and 5 cm flowers with pink petals and sepals. The lateral lobes of the lip have brown spots and the pink middle lobe has purple streaks. The species grows in the Philippines and blooms from March to August.
