Iranian seed-grown population
The seed-grown population of the Caspian provinces of Gilan and Mazandaran, planted from material introduced from India around the turn of the twentieth century and largely propagated by seed since. Iran grows and drinks a great deal of tea and appears in almost no English-language tea reference, and the plant material is a substantial part of why: there is nothing to name, no clone series to list, and a catalogue organised around named cultivars will therefore show the country as empty.
Where it sits in the botany
Iranian seed-grown population is recorded under Variety group not established, the variety group one level above cultivar. It is associated with Iran, which is where it was selected or is most widely planted rather than the only place it grows.
Where it came from
Established in the Caspian provinces from tea plants and seed brought from India around the beginning of the twentieth century, and grown since largely from seed rather than from named clonal selections.
How firm this is: Inferred rather than taken from a primary breeding or registration record. The Indian introduction and the seed-grown character of Iranian tea are consistently reported. The specific material introduced, the dates, and whether any clonal selection programme now operates were not verified against a primary source, and English-language documentation is thin.
What the plant is like
A genetically varied seed-grown population on the humid Caspian littoral, at the cold-winter margin of where tea can be grown commercially. Picked over a short season by comparison with tropical origins.
Why a grower plants it
Yield, hardiness, when it buds, what it resists and whether a machine can cut it. This is the half of a cultivar’s identity that decides what is actually in the ground, and it is usually left out of writing aimed at drinkers.
Iran sits near the northern climatic limit for tea, alongside Turkey, Georgia and northern Japan, and the constraint that defines all of them is winter rather than summer. A seed-grown population at that margin has an advantage a clonal field does not: genetic variation means a hard winter or a disease pressure culls some bushes and not others, whereas a single clone that fails, fails everywhere. The corresponding cost is the usual one — low yield, uneven flush, expensive fine plucking — and Iranian production has long been under pressure from imported tea competing on price, which makes the capital case for replanting harder rather than easier.
What it does in the cup
Iranian black tea is generally light in body and colour and mild in astringency compared with Indian or Kenyan black tea, which suits how it is drunk: brewed strong in a two-tier pot and diluted to taste, often taken with sugar held in the mouth rather than stirred in. TeaHQ states this as reported practice and general character, not as a measured profile.
How much of this is really the cultivar?
There is no cultivar claim available here at all, and that is the record's point. A country producing a meaningful share of the world's tea has no named plants to attach a story to, so it is absent from a literature organised around names — and its absence gets read as insignificance. The same shape applies to Turkey, to parts of Georgia and to a great deal of smallholder tea everywhere. What is in the cup is set by a short cool-climate season, a mild seed-grown population and a preparation method built around dilution, and none of those has a name that fits on a label.
Cultivar, growing site and processing all shape a cup, and the cultivar is very often the smallest of the three. It is also the one that fits on a label, so almost every commercial incentive runs toward overstating it. This section is on every cultivar page that has been reviewed for it, including the ones where the honest answer is “less than you would think”.
What it is usually made into
The categories this cultivar is typically processed into. It is a statement about common practice, not a limit — processing decides the category, and a cultivar can be taken down more than one route.
- Black tea — Tea taken deliberately through full enzymatic oxidation, giving the dark leaf, amber-to-red liquor and malty or brisk character most Western drinkers think of as simply 'tea'.
