Tropical Houseplants That Need Warmth and Humidity

Most of the plants sold as houseplants come from tropical forests, where the temperature rarely drops below 15 °C and the air is humid year-round. Indoors that translates into two rules: keep them warm, and don't let the air get too dry. The species below all have a minimum preferred temperature of at least 15 °C (59 °F) and a minimum preferred humidity of 50% or more in PlantoScan's data — alocasias, anthuriums, calatheas, monsteras, philodendrons, begonias and many more.

Cold is the main killer. A night on a single-glazed windowsill in winter, a cold draught from a door or a spell next to an air-conditioning vent can scar leaves or cause them to drop. Keep tropical plants away from glass in winter, and don't let them sit outdoors once nights fall below their minimum. Humidity is easier than it sounds: grouping plants together, a pebble tray, a humidifier or a spot in a bright bathroom or kitchen all help. Most of these plants prefer bright indirect light and evenly moist but well-draining soil, and many grow fastest from spring to autumn — reduce watering and skip fertiliser during winter.

Frequently Asked Questions

What temperature do tropical houseplants need?

Most need at least 15–18 °C (59–64 °F) and do best between about 18 and 27 °C. Each care guide shows the plant's own temperature range; the minimum for every plant on this list is 15 °C or higher.

How do I raise humidity for tropical plants?

Group plants together, stand pots on a tray of wet pebbles, run a humidifier, or keep them in a bright bathroom or kitchen. Misting only raises humidity for a few minutes.

Can tropical houseplants go outside in summer?

Yes, once night temperatures stay above the plant's minimum — typically 15 °C for this list. Start in shade to avoid sun scorch and bring them in before autumn nights cool down.
