Plant Name
Oxalis Purple
Scientific Name
Oxalis triangularis
Overview
Oxalis Purple is a compact ornamental plant commonly grown as a houseplant or container plant. The plant is known for its triangular purple leaves that move in response to light, opening during the day and folding closed at night.
Oxalis Purple care focuses on providing bright light, moderate watering, and soil that drains well. When planted in suitable conditions, the plant maintains steady growth and produces occasional flowers.
Plant Description
Oxalis Purple forms clumps of slender stems emerging from underground bulbs. These stems support distinctive triangular leaves that display deep purple coloration.
The plant maintains a compact size and gradually expands through clump formation.
Flower Description
Small flowers may appear above the foliage on slender stems. These blooms are typically pale pink to white and appear periodically during active growth.
The flowers are delicate and contrast with the dark foliage.
Foliage Description
Leaves are triangular and composed of three leaflets that form a butterfly-like shape. The deep purple color creates strong contrast with surrounding plants.
The foliage opens in bright light and closes during nighttime or low-light conditions.
Deciduous or Evergreen
Herbaceous perennial that may enter a dormant period during part of the year.
USDA Grow Zones
Perennial outdoors in zones 8–11. Commonly grown indoors as a houseplant in all regions.
Mature Height and Width
6–10 inches tall
8–12 inches wide
Growth Habit
Compact clumping plant with upright stems and spreading foliage.
Native Range
The species Oxalis triangularis is native to South America, particularly Brazil.
Sun Exposure
Bright indirect light provides the best growth. The plant tolerates partial sun but should be protected from prolonged intense direct sunlight indoors.
Soil Requirements
Oxalis Purple growing conditions require soil that drains well. A loose potting mix that allows excess moisture to drain freely supports healthy roots.
Heavy or poorly drained soil may cause bulb rot.
Water Requirements
Provide moderate watering during active growth. Allow the top layer of soil to dry slightly between watering cycles.
Reduce watering during dormancy.
Fertilizing
Light fertilization during the active growing season can support steady foliage development. A balanced houseplant fertilizer applied periodically is usually sufficient.
Pruning and Maintenance
Minimal pruning is required. Remove damaged or aging leaves to maintain plant appearance.
During dormancy, foliage may naturally decline before new growth appears.
Pests and Problems
Oxalis Purple may occasionally experience aphids, spider mites, or fungus gnats. Maintaining proper watering and airflow helps reduce pest problems.
Disease Resistance
When grown in well-drained soil and proper lighting conditions, the plant shows good resistance to common plant diseases.
Heat Tolerance
Oxalis Purple tolerates moderate indoor temperatures and warm outdoor conditions during the growing season.
Cold Tolerance
The plant is sensitive to freezing temperatures and should be protected from frost.
Landscape Uses
Oxalis Purple is commonly used as a houseplant, container accent plant, or shaded garden plant in warm climates. The foliage color adds contrast to mixed container plantings.
Container Growing
Oxalis Purple performs very well in containers and indoor planters. Use containers with drainage holes and a well-drained potting mix.
Container-grown plants may require periodic repotting as the clumps expand.
Companion Plants
Oxalis Purple pairs well with other foliage plants including:
Ferns
Caladium
Begonia
Coleus
Pothos
These plants share similar lighting and watering preferences.
Wildlife Value
When grown outdoors, the flowers may attract small pollinators such as bees.
Is It Edible or Medicinal
Oxalis species contain oxalic acid and should not be consumed in large quantities. Oxalis Purple is grown primarily for ornamental use.
Why Oxalis Purple Stops Growing
Growth may slow when the plant enters dormancy or when light levels are insufficient. Providing bright light supports continued growth during active periods.
Why Oxalis Purple Gets Leggy
Leggy growth may occur when plants receive inadequate light. Stems stretch toward available light sources.
Moving the plant to a brighter location usually improves growth.
Why Oxalis Purple Dies or Declines
Overwatering and poorly drained soil are common causes of plant decline. Excess moisture can lead to bulb rot.
Why Oxalis Purple Leaves Close During the Day
Leaves normally open in bright light and close in darkness. If leaves remain closed during the day, the plant may not be receiving sufficient light.
Common Questions
Does Oxalis Purple come back every year?
Yes. It is a perennial plant and may regrow each season from underground bulbs.
Does Oxalis Purple need full sun?
No. The plant performs best in bright indirect light or partial sun.
How big does Oxalis Purple get?
Plants typically grow 6–10 inches tall and spread 8–12 inches wide.
How often should Oxalis Purple be watered?

Is Oxalis Purple a perennial or annual?
It is a perennial plant that regrows from underground bulbs.
Does Oxalis Purple come back every year?
Yes. The plant may enter dormancy but typically regrows during the next growing cycle.
How fast does Oxalis Purple grow?
Growth is moderate and steady during active growing periods.
Does Oxalis Purple need full sun?
No. Bright indirect light or partial sun provides the best growing conditions.
How often should Oxalis Purple be watered?
Water when the top portion of the soil becomes dry while avoiding waterlogged soil.
Why is my Oxalis Purple dying?
