Spiranthes tuberosa

Little lady's tresses, or Spiranthes tuberosa, thrives best in regions with mild temperatures, favoring a temperature range of 50 to 95°F (10 to 35°C). To ensure the plant remains healthy and vibrant, it is recommended to regulate indoor heating or make similar adjustments during colder seasons to maintain this preferred temperature range.

Despite its strong cold resistance, 'Little lady's tresses' may need special care when winter temperatures are expected to drop below -25°C. To protect the plant in such conditions, you can cover it with materials like soil or straw. Additionally, it's advisable to water the plant abundantly before the first freeze of autumn, ensuring the soil is moist and ready to freeze. This preparation helps to prevent drought and water scarcity for the plant during the winter and the early spring months.

Temperature stress in 'Little lady's tresses' manifest differently under low and high temperatures. When temperatures fall below -25°C, the plant may show delayed sprouting or fail to sprout at all come spring. The recommended solution is to remove any non-sprouting parts in spring. On the other hand, when temperatures climb above 35°C, especially exceeding 41°C, you might notice the leaves turning lighter, curling, getting sunburnt, or the plant wilting and drying out. Mitigating this involves trimming sunburnt or dried parts, relocating the plant for shade during peak sun or using a shade cloth, and ensuring the soil remains moist with morning and evening watering.
