Talk:Rhododendron

subgenera

What titles should we have for the subgenera pages? 'Pentanthera' seems a bit ambiguous, so would 'Rhododendron/Pentanthera' or 'Rhododendron, subgenus Pentanthera' be more appropriate? The same issue will occur when we get to sections, subsections and alliances. --DWeir

Yes. I just added a stub and photo for dwarf azalea, but don't know how to link it here, because I don't know which subgenus. It's Rhododendron atlanticum. Anyone with better botany books? Pollinator 08:15, 18 Feb 2004 (UTC)

Rhododendron gardens

I removed the following two paragraphs for further checking when rewriting the page, because they (almost) contradict each other.

The largest natural rhododendron garden in the world is in Bakersville, North Carolina in the USA. The garden is situated on the top of Roan Mountain state park.

One of the largest, if not the largest, collection of cultivated rhododendrons, is in Dunedin, New Zealand, where its temperate climate is well suited. The city hosts an annual Rhododendron Festival (http://www.rhododunedin.com/).

As one of these is wild growing species and the other a collection of cultivated varieties in a garden, they dont contradict eachother but both are factually incorrect. There are far larger concentrations of wild rhododendrons in China and the Himalaya. And Dunedin's collections are much smaller than many in UK, Germany and USA. —Preceding unsigned comment added by 86.29.13.126 (talk) 12:41, 1 November 2008 (UTC)

Pakistan

Could someone please find out which (if any) of the innumerable Rhododendron species is a national symbol of Pakistan? Surely that distinction cannot be applied to the entire genus. -- Visviva 12:21, 16 September 2006 (UTC)

The national flower of Pakistan is jasmine. The government web site of Azad Kashmir does not say what the state flower is. It does say that traditional carving motifs are dragons and lotus flowers. It seems like picking a living thing as a national emblem would be contrary to strict Islam (as idolatry.) R. campanulatum ssp. campanulatum (as distinct from ssp wallichii and ssp aeruginosum) can be found in Kashmir, perhaps even Azad Kashmir. R. lepidotum also occurs in Kashmir but is unlikely to be the state flower since it only grows high in the mountains. It is likely that there are other rhododendrons in Kashmir since it is so close to Nepal and thus close to the tremendous diversity of rhododendron species in the eastern Himalayas. No rhododendron is a national symbol of Pakistan as a whole. Bob 06:58, 18 September 2006 (UTC)

The picture in the article by Molyneux shows a rhododendron in Kashmir with pink flowers. R. campanulatum has white to purple flowers. I can not find a large leaved rhododendron in that part of the world with pink flowers. My suspicion is that the painting is a romanticized vision rather than an accurate representation of rhododendrons in Kashmir. I can not confirm my suspcions since it is highly unlikely that I or anyone I know will ever visit any part of Kashmir. Bob 07:20, 18 September 2006 (UTC)

Tsutsusi

Subgenus Tsutsusi: about 15 species; type Rhododendron indicum. Is this correct? ja:サツキ is about Rhododendron indicum, and it says ツツジ, which normally romanized is "tsutsuji". "Tsutsusi" is not a normal romanization of anything, but "Tsutsushi" (or "Tutusi") would be the closest one to it. I've no idea about plants, I just came to look if there was an English article for サツキ (too bad there isn't).. -- 82.103.215.236 01:18, 12 January 2007 (UTC)

Deer

I was looking in this article to see if deer eat Rhododendron. I would like to plant on Long Island, New York, but worry about the deer population eating them. It would be good to include in the article too. -- K72ndst 23:42, 15 September 2007 (UTC)

flower is PINK —Preceding unsigned comment added by 208.98.144.98 (talk) 16:44, 9 October 2009 (UTC)

As Invasive

When I visited southern Ireland, I was struck by their rhododendron problem. Apparently, it has become quite the invasive pest there.

Oops, I see now there is a reference to invasiveness in the Classification section. I should have searched first. Still, seems like a section is warranted?

—Preceding unsigned comment added by 67.188.132.84 (talk) 01:34, 18 October 2009 (UTC) 

I agree. This plant is an invasive species in upland Britain too, and is very difficult to control and eradicate. I was surprised to find little reference to this in the article. --Ef80 (talk) 18:35, 16 May 2010 (UTC)

Grammatical considerations

What is the plural of "rhododendron"? Rhododendrons or rhododendra? JKeck (talk) 17:16, 3 July 2010 (UTC)

Supercool

I just heard that Rhododendrons can supercool their fluids to survive very low temperatures. Need to find a cite, but could be cool for the article. --Jake (talk) 17:39, 19 November 2010 (UTC)

e.g. http://books.google.com/books?id=9Eo_75CbhVcC&lpg=PA1&ots=I0x-i8IJw1&dq=rhododendron%20supercooling&lr&pg=PA21#v=onepage&q=rhododendron%20supercooling&f=false

When Do Rhododendron Flower?

I came across the article wanting to know when they flower, and I can't see any mention of this, seeing as I don't know the information I can't add it.

Would love someone to though, please :)

This is my first ever suggestion on a wiki page, I hope I've done it OK? — Preceding unsigned comment added by ClaireBoyles (talk • contribs) 10:45, 8 March 2014 (UTC)

In a colder climate, some flower in spring and some in early summer, but it varies according to species. You have to look up the species of rhododendron that you're curious about. — Eru·tuon 19:09, 8 March 2014 (UTC)

Species

Since we have a separate page for species, may I suggest that the selected species list on this page only list species that are mentioned in the text and have their own page. --Michael Goodyear (talk) 15:51, 14 June 2014 (UTC)

Since there seems to be no objection I will transfer the species list --Michael Goodyear (talk) 03:04, 28 June 2014 (UTC)

Taxonomy

This is very complex, and should eventually be split off --Michael Goodyear (talk) 03:04, 28 June 2014 (UTC)

I have a few proposed edits for additions to the taxonomy portion of the article. According to my listed sources, there are 28 different subsections in section Rhododendron and 7 different subsections in section Vireya.

Distribution Map

I have a source for a distribution map that I feel is important to the article.
IRVING, E. and R. HEBDA. 1993. Concerning the origin and distribution of rhododendrons. Journal of the American Rhododendron Society 47: 139–162.

https://www.rhododendron.org/images/Irving01.jpg

This map shows the distribution of all major subgenera of Rhododendron except for Azaleastrum.
