How to choose flowers? Pick suitable varieties according to indoor temperature
Temperature is an important condition affecting
the growth of flowers. The suitable temperature for the growth of most flowers is between 10 and 25°C. Too high a temperature will cause the proteins in the flowers to coagulate and denature, destroy the chloroplasts, and increase nutrient consumption. Too low a temperature will reduce the vitality of the protoplasm in the flower cells and weaken the root absorption capacity, causing damage to the flowers in mild cases and death in severe cases.
To avoid these phenomena, we can choose suitable flowers and plants to grow according to the indoor temperature. Especially in winter, if you do not understand the overwintering temperature of flowers and casually bring a certain flower into the house, it is very likely that they will not be able to overwinter safely. Chrysanthemums, Japanese evergreen (Rohdea japonica), peonies, plum blossoms, pomegranates, crabapples and others are cold-tolerant flowers, native to temperate and frigid zones. They can generally withstand short-term low temperatures of -3 to 5°C, grow at 5 to 10°C, and grow luxuriantly at 10 to 25°C. Broadleaf lady palm (Rhapis excelsa), sago palm (Cycas revoluta), Chinese fan palm (Livistona chinensis) and others are warmth-loving
flowers, generally growing luxuriantly above 25°C, showing slow growth below 10°C, and entering dormancy below 5°C. White orchid (Michelia alba), Chinese hibiscus (Hibiscus rosa-sinensis), jasmine and others need 6 to 10°C to overwinter safely. Cyclamen, fuchsia, geranium and others cannot go below 10°C, while for plumeria, poinsettia, glasswort (Peperomia), and the succulent flowers such as candle plant (Senecio articulatus), epiphyllum, night-blooming cereus (Epiphyllum oxypetalum), and agave, the room temperature cannot be below 12°C.
Expert comment: Once you have chosen the right flower species, you will not need to waste too much time and energy on temperature issues in daily life. But issues such as environment, light, ventilation, and watering still need careful attention. Grow flowers according to the different growth characteristics of the plants, as well as the orientation of the room and the light duration.
Expert advice: Choose according to indoor temperature. Generally speaking, in areas without indoor heating facilities in winter, the indoor temperature can only be maintained at around 0 to 5°C. For such rooms, you can choose some flowers that are slightly tolerant of low temperatures, such as: asparagus fern (Asparagus setaceus), geranium, rubber tree (Ficus elastica), broadleaf lady palm (Rhapis excelsa), ivy, asparagus fern (Asparagus cochinchinensis), green giant (Spathiphyllum), dwarf umbrella tree (Schefflera arboricola), Norfolk Island pine (Araucaria heterophylla), and others. These flowers and plants are slightly cold-tolerant and can grow well at such temperatures.
If the indoor temperature can be maintained at around 8°C, in addition to the above flowers, you can also grow foliage plants such as money tree (Pachira aquatica), clivia, pothos, bromeliads, and Brazilian ironwood (Caesalpinia ferrea). If the room temperature can be maintained above 10°C, the range of choices is even greater. Anthurium, cyclamen, crabapple, bird's nest fern (Asplenium nidus), bougainvillea, Japanese evergreen (Rohdea japonica) and others can all be chosen for growing. A tip for you: you can place the flowers on a sunny windowsill or balcony to ensure sufficient light. In addition, pay attention to watering; the pot soil should not be too dry or too wet. In a low-temperature environment, potted flowers grow slowly and their demand for nutrients gradually decreases. At this time, apply a small amount of fertilizer, just enough to maintain nutrition. Never water or fertilize heavily, to avoid root rot and disease.
