Aquarium plant species: compare light and care needs

The finder is for deciding. This is for reading. Every plant the hub holds, with every field it holds, sortable on any column. Nothing is ever removed from this page, including the plants nobody should buy and the plants nobody may collect, because you cannot judge a catalog you cannot see.

Sort by the last two columns first. They carry the finding this page was built to publish. Sort by wild in Armenia and you get 42 plants with an occurrence record here, headed by 3,559 sedge records and 101 marsh marigolds1. Sort by buyable here and you get 34 named lines at one shop in one city. The two sets do not intersect anywhere. Everything the country grows, you cannot buy, and everything you can buy, the country does not grow.

Every field

Click any heading to sort. Click it again to reverse it, and once more to go back to the order the file was written in.

Plants with no published figure for the column you sorted on always sink to the bottom, in both directions, because a missing figure is not a small figure. The table scrolls sideways and the plant name stays legible. On a phone this is a wide table and it is meant to be: the alternative is hiding columns, and hiding columns is what this page exists not to do. Under each row sits the warning, the propagation method, the note and the sources for that row.

A zero in the wild column means nobody uploaded a record, not that the plant is absent. Arrowhead is the worked example. GBIF holds no records for the genus in Armenia1, and Barseghyan records two Sagittaria species from bogs, lake banks and rice paddies at Sarvanlar, Nejirlu, Zangilar, Stepanavan and Kalinino between 850 and 1400 meters2. A herbarium checklist compiled by a specialist who walked the ground beats an absent database row, so that plant is recorded as native with the occurrence count left empty. The reverse trap is in the same file: Barseghyan names Vallisneria spiralis in a passage listing what the Colchis and Talysh wetlands have and Armenia does not, and reading that as an Armenian record would be exactly the kind of mistake this hub exists to avoid.

How to read it

Five columns carry more weight than the rest.

Light

The band and its floor in micromoles per square meter per second at the substrate. Low is 15 to 30, medium 30 to 60, high 60 to 120 or more5. Those bands are hobby convention and no measurement study behind them could be found, so the number is a floor to compare your own reading against, not a specification.

Feeds via

Roots, leaves, or both. Epiphytes, floaters, mosses and stem plants feed from the water column, and root tabs are for swords, crypts, Vallisneria and bulb plants5. Measured for carbon in five species: 98 percent of photosynthesis from roots in an isoetid, 75 in Vallisneria americana, 28 in Ludwigia repens, and zero in Hydrocotyle6.

Yerevan tap

Derived, not published. All districts means the plant's own pH and hardness ranges cover the whole of measured Yerevan tap, GH 2.9 to 10.9 and pH 6.0 to 7.39. Some districts means it overlaps but does not cover, so test your own water. Yerevan tap is not one water and a plant that suits Davtashen may not suit Nork.

Wild in Armenia

The georeferenced occurrence count for country code AM, read from GBIF on 9 September 20261. A plant that grows wild here has already proved it survives an Armenian winter and an Armenian summer, and no datasheet is stronger evidence than that. It says nothing about whether you may collect it.

Behavior

An invasive warning is not a comment on how fast the plant grows in your tank. It means the plant is on the EU list of invasive alien species of Union concern7, or on the Armenian Red Book with a per-specimen tariff attached, or a documented invader somewhere that matters. Open the row and read the warning.

Six rows you should not treat as a shopping list

Everything a person would want to take from a wild Armenian pond is protected. Everything that is not protected is a pondweed or a sedge.

The Red Book of Plants of Armenia was approved by Government Decision N 72-N of 29 January 2010 and registers 675 plant species3. The per-specimen compensation tariffs come from law HO-88-N, and run 25,000 AMD for Salvinia natans and Nuphar lutea, 15,000 for Nymphaea alba and Utricularia intermedia, and 10,000 for Menyanthes trifoliata, Najas minor and Iris sibirica. Selling, buying, exchanging, exporting or importing an illegally collected Red Book plant is charged at five times the tariff4.
