Both regular and large-leaf and a hairy-leaf form are known. 1
There are 2 known species of synsepalum that carry miracle fruits. Synsepalum dulcificum is a smaller-leaf version (leaves are narrow), and is somewhat slower growing plant. Synsepalum subcordatum (Giant Miracle Fruit) is a larger leaf variety, and grows into a small tree. The fruit are slightly bigger than those of S. dulcificum, and are produced more profusely, especially in first years. With age, the fruit crop amounts of these two species become about the same. 13
The Miracleberry (Synsepalum dulcificum) (family Sapotaceae) is a large shrub (reaching 2 to 5 m tall) with dense foliage clustered at the tips of its many slender branches. It is native to West and West-Central tropical Africa. This plant is best known for its red berries, which contain a glycoprotein known as miraculin. Miraculin has the remarkable property of modifying sour tastes into into sweet (Kurihara and Beidler 1968). William Freeman Daniell (1852, cited in Kurihara and Beidler 1968) provided the first report in the scientific literature of this unusual property of Miracleberry fruits. 14

The fruit is a small bright red, ellipsoid berry approximately 2 to 3 cm long and containing a single seed. Although not sweet itself, when a single fruit is eaten and the fleshy pulp allowed to coat the taste buds of the tongue and inside of the mouth, an extraordinary effect occurs. The fruit will now allow one to eat a slice of lemon or lime without wincing. The marvelous aroma and inherent sweetness of the citrus remains but the sourness is almost completely covered. The effect remains for some 30 minutes or more. 1
"In the writer's opinion, one fruit worked in the mouth long enough to remove all the pulp from the smooth, shiny single seed, gives maximum results, and consumisng additional berries does not tend to increase its potency. The sweet-inducing properties of this "taste-twister" can linger on for up to three hours and the flavor of fruits, such as fresh strawberries, can be greatly enhanced when certain delicate flavors, formerly masked by table sugar, are released and experienced for the first time." 6

The miracle fruit, upon attaining a height of two to three feet in four years or less, can produce fifty or more berries at one time. The main crop comes in winter, with larger plants tending to bear some fruit most of the year. Setting plants out in alkaline soils should be avoided; peat moss is one of the best mediums for potting up these acid-loving fruits. 6
How is this fruit pollinated? Some references exist that say it is ‘self pollinated’ and I found none showing insect or animal pollination. The shape of the flower, and the fact that many of them face downwards, suggests gravity as a mechanism. 18
By seed. Seeds should not be dried out before planting.
When propagating miracle fruit, sow the seeds in a rich, well-drained medium, just barely covered, and water lightly every other day. Seeds generally come up in about eight to ten weeks, but grow slowly the first year, often being only two to three inches tall at the end of almost one year of growth. It really takes three to four years before the plants reach a height of more than fifteen to twenty inches, and then they start to grow more rapidly.
Although it can be rooted from cuttings under mist, cuttings generally take a long time to root and don't seem to grow as fast as seedlings. So, in commercial production, almost all miracle fruit are still propagated from seed. On large plants, it might be feasible to attempt air-layerings, or even grafting from bearing ones to seedlings, but I don't know of anyone who has tried it. 14

An acid soil is a must for miracle fruit. They prefer a soil acidity of pH 4.5 to 5.8. This can be achieved by planting in equal parts Canadian acid peat and pine bark. Also peat and perlite mixes are said to give excellent result. 1
Growing instructions for this plant from Top Tropicals Nursery pdf
The plant should be fertilized every two to three months with a good quality balanced
Be sure that the soil is well draining as the plants do not like to sit in wet soils. Coming from a tropical climate they need highly humid conditions. 1

It is unfortunate that heat destroys the active principle, so that canning, jams, preserves, baking, drying, etc. are impossible. The fruits can be held for a short period of time by refrigeration or freezing. 12
Miraculin differs from most other "sweet-tasting" proteins in that it is a taste modifier, without itself having a sweet taste. In general, "sweet-tasting" proteins may be classified into three categories: the protein itself is sweet (thaumatin, monellin, mabinlins, pentadin and brazzein), the protein induces sweetness (miraculin), or both (neoculin, the heterodimeric form of curculin) (Hiwasa-Tanase et al. 2012). 14
Synsepalum subcordatum (Giant Miracle Fruit) is called Munga in India 16
The Synsepalum subcordatum - large leaf variety's fruit does not cause the 'miracle' or taste-twisting. 19
