A member of the Chicle family (Sapotaceae), which includes Mamey Sapote and Sapodilla, Miracle
Fruit is the best known of 29 species in the Synsepalum genus.
A shrub or, in its native environment, a small tree.
At least 25 years.
Slow in the first year, then between slow and moderate, depending on conditions.
Normally no more than 6' high, but up to 15' in a favorable climate.
Five white petals wrapped in a tubular shape, opening fully once pollinated. The flowers are
grouped in small clusters.
Several times a year in frost-free regions.
Yes, when hand pollinated with a tiny artist brush or a toothpick. A second plant nearby
may improve pollination rates.
Years before fruiting:
The plant starts to flower when about 1-1.5' tall, in 2-4 years, depending on growing conditions.
The flowers will set fruit when the plant is about 2' tall.
Oval with a small point or nipple, about 1" long, thin skin changing from green to strong red
when ripe, pink translucent flesh, with a single seed. The raw fruit causes one's mouth to
taste sour foods as sweet.
Months for fruit to ripen:
Storage after harvest:
This fruit can be eaten raw or frozen immediately. It spoils quickly and cannot be cooked
without losing its flavor-changing properties.
Green, elongated, smooth margins. New leaves are red and turn green over time.
Fibrous, not invasive.
The flowers do not noticeably attract insects; a native pollinator has not been identified.
The fruit attracts birds.
Toxic / Danger:
Central West Africa.
Cultivation and Uses
USDA hardiness zones:
10b-11. Young plants are killed at 32°F. Older plants will survive 32°F for short
periods. This tropical plant may experience leaf loss below 40°F.
Young plants need moist soil but become somewhat drought tolerant with age.
Outdoors, in temperatures over 85°F, all day open shade with no direct sun. All day part
shade in lower temperatures. Indoors, by a south-facing bright glass window kept closed.
This plant is best grown indoors, next to a south-facing window, in a well-draining container.
The container must contain extremely acidic soil. The plant should be repotted,
every 1-2 years, in a pot one size larger, with more extremely acidic soil, otherwise growth
Located outdoors, it needs all day open shade when temperatures exceed 85°F. It should
be brought inside when temperatures are expected to go below 40°F.
50% peat moss and 50% perlite, moist, well drained, pH 4.0-5.0 (extremely acidic). The mix
must provide both airflow and moisture, which can be adjusted with more peat moss to stay moist
longer, or more perlite to dry faster. The plant will grow in pH 5.1-5.5 (strongly acidic) soil
but will not grow as fast or be as healthy.
Apply liquid plant micronutrients to irrigation water, at a rate of 1/4 teaspoon in one gallon
of previously acidified water, every time the plant is watered. Apply a small amount of organic
fertilizer every 3 months to the top of the soil. Adding a small amount of iron sulphate to
the fertilizer will also improve growth.
Water after becoming established:
The soil must always be moist, never too wet and never too dry, when the plant is young, when
temperatures go over 85°F, and in low humidity. Adjust the soil mix so that it needs water
every 5-7 days, using water supplemented with citric acid and vinegar to lower the pH between
4.0-5.0. Use litmus paper strips (pH test strips) or a reliable pH meter to measure soil and
When the plant is grown outdoors, organic mulch spread over the root area can reduce soil
evaporation loss. Mulch should not be used indoors.
There is usually no need to prune this plant. It blooms on one year old wood.
Use fresh seed, which will take 4-10 weeks to sprout. Sprouting in pH 4.0 soil will cause
quicker germination. Seed become non-viable within 1-2 days after exposure to air and do not
survive being dried or frozen. Cuttings take a long time to root and must have low pH soil.
The fruit, when eaten so that tongue and teeth remove all flesh from the seed, change the
flavor of sour foods to sweet. Two to three fruit are needed for the full effect, which lasts
one-half to one hour.
Another name for this fruit is Miracle Berry.
This plant does not need high humidity when it has continuously moist, extremely
acidic soil. Most plants cannot handle soil so acidic.
