Hothouse plant is a term used to describe a plant that requires a lot of care and attention to grow and thrive. Some synonyms for this term include delicate plant, exotic plant, fragile plant, high-maintenance plant, and tropical plant. These types of plants typically require consistent watering, high humidity, and specific temperatures to survive, making them difficult to care for outside of a hothouse or greenhouse environment. Hothouse plants range from orchids and ferns to succulents and cacti, each with their own unique requirements for growth and survival. Whether you're an experienced gardener or a novice, tending to hothouse plants requires patience, knowledge, and a lot of TLC!
