What are the plants that can survive freezing? My house in Shandong does not have heating. If you know, please tell me.

1 Hemerocallis

Strong and cold-resistant, it can survive the winter in the open field in North China. It has strong adaptability, likes moisture but tolerates drought, likes sunshine and tolerates semi-shade. It is not very selective for soil, but moist soil rich in humus and well-drained is suitable.

2 Phlox

It likes warmth, is cold-resistant, and avoids intense heat. It can survive the winter in cold beds in North China. It prefers well-drained, loose loam soil that is not drought tolerant and avoids waterlogging. Commonly used for propagation are sowing in autumn in warm areas and spring in cold areas. The optimum temperature for germination is 15-20℃. Seed viability can be maintained for 1-2 years. After sowing in autumn, the seedlings can be transplanted to cold beds to survive the winter in early or mid-October. They can then be moved to the ground in early spring and fertilized in time. They can be planted in mid-April. The flowering period is longer. The maturity stages of the capsules vary. To prevent the seeds from scattering, the inflorescences can be cut off when most of the capsules turn yellow, dried and threshed. Phlox plants are short and have rich flower colors. They can be used as plant materials for flower beds, flower borders and rock gardens, and can also be used as potted plants for indoor decoration. Varieties with taller plants can be used as cut flowers.

3 Rose flowers

It has strong adaptability, is cold and drought tolerant, and has no strict soil requirements, but slightly acidic sandy loam rich in organic matter and well-drained is best. It likes light, but too much direct light is detrimental to the development of flower buds. The petals are easily scorched, and high temperatures in summer are detrimental to flowering.

4 Dianthus

It likes sunshine, is cold-tolerant, tolerates drought, avoids waterlogging, and prefers well-drained, fertile sandy loam.

It is cold-tolerant but not intolerant to heat. It likes sunny, high-dry, ventilated, and well-drained fertile loam. Sowing and cutting are used for propagation. The optimum temperature for seed germination is 21 to 22°C. Sow in autumn and plant in the following spring. For double-flowered varieties that are not easy to bear fruit, divide or cut in autumn. The whole plant of Dianthus dianthus is medicinal and has the effect of clearing away heat and diuresis.

Dianthus is a perennial flower of the Caryophyllaceae family, and is now mostly cultivated as a biennial flower. Plant height 30-50 cm, white-green. Stems are bushy, smooth and hairless. Leaves are strip-shaped or lanceolate. The flowers are solitary, single or double, in light red, red, light purple, purple, white, complex colors, etc., with serrated edges on the petals; the flowering period is from May to September. The capsule is oblong and the seeds are black. Another one produced in Europe is called American Dianthus, and its flowers are cymes.

In addition, there are also plants such as wisteria, golden-leaved fragrant vine, American thorn, aquatic iris and arrowheads, which all meet your needs.
