Mini Anthurium 'Midori'
Anthurium andraeanum 'Midori'
flowerMini Anthurium 'Midori' is a compact tropical houseplant prized for its striking deep green, heart-shaped spathes (modified leaves) with contrasting yellow spadices (flower spikes). This cultivar produces smaller flowers than standard anthuriums, making it ideal for tabletops and small spaces while maintaining the characteristic long-lasting blooms the genus is known for. The foliage is equally attractive, featuring glossy, dark green leaves that add ornamental value year-round.

Growing Conditions
Soil
Growth Stages
Establishment
2-4 weeksPlant is acclimating to new environment; growth is minimal; foliage may appear stressed
Maintain consistent humidity (60-80%), warm temperatures (70-85°F), and indirect light; avoid fertilizing for 4-6 weeks; allow roots to establish
Vegetative Growth
4-8 weeksNew leaves emerge regularly; plant develops stronger root system; no flowers yet
Provide bright indirect light, consistent moisture, and high humidity; apply diluted balanced fertilizer monthly; rotate plant weekly for even growth
Pre-flowering
2-4 weeksLeaf development slows; flower spikes may begin to form at leaf axils; plant appears more mature
Maintain warmth (minimum 60°F at night), increase humidity, and continue balanced fertilizing; reduce nitrogen slightly to encourage blooming
Flowering
2-3 months per bloom cycle (continuous in ideal conditions)Heart-shaped spathes unfurl in deep green or red with prominent yellow spadices; blooms emerge continuously from established plants
Maintain optimal conditions; provide phosphorus-potassium rich fertilizer every 2-3 weeks; gently mist foliage; provide bright indirect light to sustain blooms
Bloom Maintenance & Renewal
Ongoing (anthuriums bloom year-round indoors)Older spathes fade to green and eventually drop; new flower spikes continue emerging from healthy plants
Remove spent flowers by cutting at base near leaf axil; maintain consistent care; fertilize every 2 weeks; provide 8-10 hours of bright light daily

Uses
Ornamental Use Only
CulinaryWhile not for consumption, anthuriums are toxic if ingested due to calcium oxalate crystals. They are purely ornamental houseplants. [source]
Indoor Air Purification
HouseholdAnthurium plants help filter indoor air by removing ammonia, formaldehyde, and xylene. Their large surface area leaves contribute to air quality improvement in home and office environments. [source]
Cut Flower Arrangements
CraftMini anthuriums are prized for floral arrangements and corporate decorations. Their long vase life (3-4 weeks) and striking appearance make them valuable in the cut flower industry. [source]
Pollinator-Friendly Indoor Plant
WildlifeThe spadix of anthurium contains numerous small flowers that attract pollinators indoors. While primarily self-pollinating, they can attract beneficial insects when grown near windows. [source]
Traditional Medicinal Uses
MedicinalIn some tropical regions, anthurium is used in traditional medicine for anti-inflammatory and anti-microbial properties, though scientific evidence is limited. The plant should not be ingested due to toxicity. [source]

Harvest Tips
Anthuriums are grown for ornamental blooms rather than harvest. Cut flowers at the base of the spike once spathes are fully unfurled and can be enjoyed indoors for 4-6 weeks. Remove spent blooms to encourage new growth. Do not deadhead flowering stems completely until multiple new buds emerge.
Fun Facts
- 🌱 Anthurium 'Midori' is native to the rainforests of Colombia and has been hybridized extensively for compact houseplant cultivation; the name 'Midori' means 'green' in Japanese, reflecting its deep emerald spathe color.
- 🌱 Mini anthuriums can bloom year-round indoors under consistent conditions, with mature plants producing new flowers every 4-6 weeks; individual spathes can remain colorful for 8-12 weeks on the plant.
- 🌱 The 'flower' is actually a modified leaf (spathe) that surrounds the true flowers, which are tiny and contained on the yellow or orange spadix; successful pollination produces decorative berry clusters.
