Fragrant evening-primrose is native to environments where temperatures range from 68 to 100 °F (20 to 38 ℃). It is particularly partial to such climes. Seasonal adjustments may be needed to meet these temperature demands, reflecting its native habitat's conditions.

Native to North America, common blanketflower grows well in a temperature range of 32 to 95℉ (0 to 35 ℃). In the hot temperatures of summer, a shaded location and a soil pH of 6.0 or higher will help the plant thrive. In the cooler temperatures of fall, cutting back the stems to 6 inches should be done to promote new growth in spring.

Japanese callicarpa is indigenous to environments with temperatures in the range of 41 to 89.6 °F (5 to 32 ℃). It favors moderate climates and can adjust to the changing seasons with minimal care.

The native growth environment for golden currant is diverse, ranging from grasslands to forests across North America, and is tolerant of temperatures between 41 to 90 ℉ (5 to 32 ℃). The plant prefers a temperature range between 50 to 77 ℉ (10 to 25 ℃), and may wilt or drop leaves if exposed to temperatures outside its preferred range. In hotter temperatures, mulching around the plant can help retain moisture and regulate soil temperature.

Lesser calamint is native to temperate environments and prefers a temperature range of 41 to 95 °F (5 to 35 ℃). Seasonal adjustments may be necessary to maintain this range, providing warmth in winter and cooling in summer.

Black mullein is known to thrive in temperate climatic conditions, particularly within a temperature range of 68 to 95 °F (20 to 35 ℃). For optimal growth, keep it in an environment close to this range, adjusting when necessary throughout the year.

Asthma-plant is originally found in environments that have a temperate climate with temperature ranges from 68 to 95 °F (20 to 35 ℃). To replicate these conditions, maintain this temperature year-round, but take extra care during colder season to preserve its warmth.
