A family of arrowroots. Homeland - the tropics of America. In nature, there are 15 species. Stromantu is often confused with calathea and even with ktenant. In fact, some botanists do not even distinguish stromanthus in a separate genus and do not share it with calathea.
The culture is widespread Stromanthe blood-red Stromanthe sanguinea is a tall plant, up to 1 m in height, leaves about 20-30 cm long, narrow oval or lanceolate. Its varieties differ somewhat in the color of the leaves. Some have wide light stripes and spots on the upper side, others have only a light stripe along the central vein, but all have a purple-red underside of the leaf and petioles.

Stromanthe sanguinea 'Triostar'
- Stromanthe sanguinea 'Multicolor' The blood red multicolor stromanthe has a wide range of shades on the leaves - from white, light green to dark green, the reverse side of the leaves is burgundy. Distribution of spots in the form of small splashes on the leaf is characteristic of this variety.
- Stromanthe sanguinea 'Maroon' - has a pure green leaf blade with a pronounced lighter central vein, the reverse side of the leaf is burgundy. It is rarely found as a houseplant due to its less decorative effect.
- Stromanthe sanguinea 'Triostar' - the most common variety, has characteristic alternating spots-stripes of green, white-pink, the back of the leaf is burgundy.
Temperature: Stromanthe is thermophilic. In summer for good growth, the optimum temperature is 20-30 ° C, in winter 18-20 ° C. The minimum for her at any time of the year is 12 ° C (with dry soil, up to + 10 ° C is possible), does not tolerate a directional draft. In winter, plants should not be placed close to window panes, and cold air from unsealed frames should be feared.
Lighting: Bright diffused light or light partial shade, in bright light and in a too dark place, the color of the leaves is lost. Stromanthus belongs to shade-tolerant, but not to shade-loving plants. Most types of stromante with painted tricolor leaves require more intense lighting.
Watering: Abundant when the temperature is above 22-24 ° C, moderate if it is cooler than 20 ° C. Water only with soft and warm water. Stromanta does not tolerate chlorine and fluorine in water. If your stromant has dry ends of leaves, and the air humidity is high enough, ask if your area has a high fluoride content in tap water. Try watering with bottled water. Stromanta does not like strong overdrying and systematic waterlogging.
Fertilizer: From May to August, stromante is fed with liquid complex fertilizer for indoor decorative leafy plants every two weeks, the fertilizer is taken in a half dose. The plant is sensitive to excess or overfeeding of fertilizers.
Air humidity: Stromanta, like all arrowroots, loves very humid air - not lower than 55%, but with humidity above 80%, you need to ventilate the room more often. To increase the humidity of the air, regular spraying of the leaves is necessary. During the heating season in winter, the pot is placed on a pallet with wet pebbles or covered with sphagnum moss, which is often sprayed.
Transfer: Every year in February - March, into loose, light soil, consisting of 2-3 parts of leaf, 1 part of peat, 1 part of humus soil, 1 part of coniferous soil mixed with sand. Pieces of charcoal are added to the soil mixture. Stromanta does not tolerate lime content in the soil. You can use commercially available azalea potting mix. The container for these plants should not be deep. Good drainage is a must.
Reproduction: By division when replanting in the spring. The pots are covered with a plastic bag and kept warm until the plants take root.
