The correct reading of the name of the defined plant consists of the following: First, the genus of the plant is indicated - Calathea, then the species - rufibarba (for example) and then in apostrophes - the variety - 'Blue Grass'.
If there is no indication of the variety, or rather, the word in apostrophes is not indicated, then the variety is not known. I ask you to take into account the moment that among flower growers not only in our country, but also in the world, sometimes there is a lot of confusion with the definition, if not of species, then of varieties of many marant, there is no clear classification, and therefore very often flower growers are limited only to the name of the species, for example, roseopict. In other cases, the name of the species is omitted and the plant is called by variety, for example, Calathea roseo-picta 'Medallion' is often simply called Calathea Medallion.
Genus Calatea. Perhaps among Kalatey there are much more marant than among Ktenants. In terms of the complexity of growing calathea, the most difficult. They are more sensitive to the slightest fluctuation of cold air/draught, water temperature and water hardness when watered, as well as to air humidity (required humidity is about 85-100 percent). In addition, many of the Kalati cannot be subjected to a long procedure under the shower, and some hate spraying so much, for example, Kalatey Varshevich.
- Calathea rufibarba - this calathea does not like spraying, but is easily affected by the tick, if not moist enough air. It tolerates transplantation and division of the bush (sections are sprinkled with coal). The difference between the varieties' Blue Grass' and 'Wavestar' is that the first has a green reverse side of the leaves, the second has a lilac-bard side. With a lack of light, the leaves grow small, and their petioles are long. It grows well on loose, light substrate from a mixture of leaf humus, greenhouse earth and baking powder (vermiculite and expanded clay).
- Calathea majestica - this calathea is absolutely not afraid of water (best of all warm), and grows very quickly. She is as unpretentious as she is lanceolate. And more. Perhaps she likes small pots - since I have it growing in just that, I do not think that the reason for her growth can lie in something else... I didn't fertilize her. And the ground is mixed with sand.
- Calathea lancifolia, calathea lanceolate is a herbaceous plant with no knee braces (like the marant), growing quickly, easily and naturally. It responds well to spraying. Dushik loves, and the loosening of the soil in the pot is especially. Of all the calates herself unpretentious. I have in a dry room without a humidifier, next to the central heating and does not complain.
- Calathea pseudoveitchiana, Calathea Pseudoveitchiana. This calathea needs high humidity. From my own experience, I will say that when my Pseudoveichiana grew up in a jar, she felt more than satisfactory, she just did not like spraying (and does not like to this day), new leaves appeared large and unfolded full-fledged in color and size. However, without a jar, the plant thinned, stretched out, the leaf plate became smaller and less attractive. Growth, as before, was slow, and now. The problem is visible only in humidity.
And more. You have to be very careful with it - it can easily pick up a tick, and on it it is brought out harder than from other marants. - Calathea makoyana, kalateya Makoya is just one of those kalateya that does not like spraying (personally, I killed one Makoya in this way).
- Calathea zebrina, aka striped calathea. Very jealous of air humidity, and even more to the fertility and ventilation of the soil, i.e. roots must breathe and the substrate must be selected as light as possible, but at the same time nutritious.
