Plants That Start With R

Rabbit’s Foot Fern prefers low to medium indirect light at 50 to 150 μmol·m⁻²·s⁻¹ PPFD. A PAR meter or PAR meter app can measure this light level.

• Placement: keep it 8 ft / 2.5 m from a north, east, or west-facing window.
• Low-light option: a spot is suitable if you can comfortably read a book there without artificial lighting.
• Too much light: direct sun can bleach or scorch the delicate fronds.
• Too little light: new growth becomes sparse and weak.

Rattail Cactus needs bright direct light at 250 to 1000 μmol·m⁻²·s⁻¹ PPFD. Give it 6+ hours of direct sunlight each day.

• Placement: set it within 2 ft / 60 cm of a south or southwest-facing window.
• Keep its view of the sky unobstructed. A PAR meter or app can confirm the light level.
• Too much light: sudden exposure can scorch stems, so increase direct sun gradually.
• Too little light: stems become weak, stretched, and less likely to flower. Grow lights can help during shorter winter days.

Rattlesnake Plant grows best in bright indirect light at 150 to 250 μmol·m⁻²·s⁻¹ PPFD. A PAR meter or app can help verify this range.

• Placement: keep it 5 ft / 1.5 m from a south, west, or east-facing window.
• The leaves should not have a clear, direct view of the sky. Use a sheer curtain if sunlight reaches them.
• Too much light: direct sun can fade the patterns and scorch leaf tissue.
• Too little light: growth slows, stems weaken, and the foliage may lose some contrast.

Rex Begonia needs bright indirect light at 150 to 250 μmol·m⁻²·s⁻¹ PPFD. A PAR meter or app can be used to check the available light.

• Placement: position it 5 ft / 1.5 m from a south, west, or east-facing window.
• Prevent a direct view of the sky. Filter unavoidable sunlight with a sheer curtain.
• Too much light: leaves may bleach, scorch, or lose their rich colors.
• Too little light: growth becomes weak, and the foliage may look dull or less patterned.
