Polygonatum ID, please....

[mickeymuc]

Hi there,

From a friend I got this Polygonatum some time ago, I think the motherplant came from chen yi a long time ago. Stems are about 20 cm long, and the beautiful flowers just start to open now.
Thanks for any help !

Best regards from Munich !

Sorry for the so-so quality of the pics, it's just not the weather to stay outside for a long time....here's some more detail of the flowers

[Lvandelft]

Difficult to see but probably something like Polygonatum cirrhifolium,
Flowers vary from pink to red with shoots of about 2 m. long.
Mine is in bud, about the same colour but I would love to have a red one.

Hi,

I think it's maybe not this one, I have cirrhifolium also (which I love a lot!) , and it looks quite different (leaves with a pronounced tip and flowers much more closed and not singly but on branched inflorescences). This one resembles more P. prattii concerning leaves, habit and flower colour, but shoot length, single flowers and the wide opening flowers are very different to this one.

Thanks anyway for the idea !

Best regards,

Michael

p.s. I have a plant which is supposed to be "cirrhifolium red", but it grows very slowly and I haven't had flowers yet....

It's a bit like P. graminifolium maybe?

[mickeymuc]

Yes, the flowers look exactly like that species, but leaves and habit seem quite different from what I can see at the pics on the internet (I don't have a graminifolium...yet).

I just went out to take a picture of mine, to compare but it's too late. It's already died down for winter. The stems are upright and very fine leaved - finer than P. hookeri but longer. I wondered if yours was perhaps in a very damp or heavily shaded spot where it grew a bit laxer/looser. But it's probably a different species.

Hello,
 
 From what I see in the picture this looks like what Jeffery (Kew Bulletin, 1980-81) considered P.kansuense (except he says white flowers!). I believe the Flora of China authors for Polygonatum have lumped many species into one another with this entity thrown into P.verticillatum. Your plant should be scaberulose on the veins and pedicel. Not really sure on the filament details since this is one species I never received from Chen Yi, at least as a living plant.

 I am getting ready to do a Polygonatum pictorial on the forum as soon as I get the photos all resized and named.

 PM me.

That is good news, Aaron!
