Invasiveness and impact
Is the content of this section correct? It begins with the sentence "Ligustrum Japonicum is a fern with twining fronds ... (having) underground rhizomes" so it describes a fern, not a tree. @User:mirrordor Mirrordor (talk) 15:29, 27 April 2023 (UTC)

Information on the invasiveness of this plant in the US is incorrect
No reference is given for the assertions that L. japonicum is invasive in the United States. In Maryland, Virginia, North Carolina, and California it escapes cultivation frequently enough that it might be legitimately considered invasive. In other states it escapes cultivation so rarely that it is doubtful that it could cause harm to native ecosystems, and that is one requirement for a plant to be considered invasive. There are no confirmed observations in iNaturalist of its having escaped cultivation in Texas, Louisiana, or Oklahoma, and there are few if any for Mississippi and Alabama. Reports from other sources of its occurrence outside of cultivation in those states include neither photographic evidence nor documentation that the plant was not cultivated. (One voucher specimen from Alabama is clearly L. lucidum. Others describe plants that clearly are cultivated.)

Unfortunately, supposedly authoritative sources parrot the same language used for all privets—that they are spread widely by birds (not all species; not all locations), they build up long-lasting seed banks (L. lucidum does not build up a seed bank at all. L. sinense does not seem to, either. Given that it so rarely escapes cultivation, it seems highly unlikely that l. japonicum does, either.), they propagate aggressively by root colonization (L. japonicum and L. lucidum do not propagate by root colonization at all.), and that they form monocultures, shading out all sunlight, wherever they establish themselves (Within their naturalized ranges, several privets do. Several others, while definitely of concern, do not.).

The stated bloom period is also incorrect for the United States. (The correct bloom period is late March through April in more southern locations; late April through May at the northern end of its range.)

I do not have time to address these issues right now, but the information needs to be corrected to the extent possible and carefully referenced to appropriate sources. EditorCliff (talk) 04:57, 3 July 2023 (UTC)
