Perrenial Or Biennial? That Is The Question.

Is the yellow"Evening Primose" in the photo a bienniel or a perrenial plant?

Can't find any definitive info on this anywhere!

Best regards,

Ken.

 

With this flowering habit this will be one of the biennial species. O. X glazioviana is a common cosmopolitan weed resembling yours, however I do not see the diagnostic reddish glandular hairs of that one in your picture.

 

Thanks for your quick response Ron B.

There are no "Red Hairs" Ron, I checked, so what difference this makes to your identification I don't know!!

What is the definition of "A Weed"?

Best regards,

Ken.

 

Weed is used for plants considered pestiferous. This varies with location, a plant can be enjoyed in one place and detested in another.

 

There is one called glazioviana 'Micheli' (which I have) and it looks very similar to yours. It is a fun plant (Japanese beetles love it).

You are right Ron B,.....................as always!

See below.

Any plant that is considered undesirable. One person might think a plant is beautiful and grow it in their garden. Another might think the same plant is a weed and pull it out of their garden.www.fcps.k12.va.us/StratfordLandingES/Ecology/mpages/glossary_qz.htm


In my instance though, I consider the Evening Primrose I showed in the photo to be a delight to behold, and a nice pong from it to boot!

Many thanks Ron .B.

 

Thanks Levilyla,

I'll check it out,...........As I don't live in Japan, (U.K only) should I be concerned about the "Beatle you mentioned?



Best regards,

Ken.

 

Japanese Beetles are an introduced pest to North America and like so many introduced pests, are a bigger problem in their new environs than where they originated.

Japanese Beetle

Japanese Beatles, I suppose, could be a description or name of a tribute band of Japanese origin? I guess if a member was a gardener, they might like O. x glazioviana?

 

Well my leaves do not look as nice as yours...mine always get many holes and become very ratty looking...I also cut them back when they first start so that they are shorter and fuller and no need to stake. I still love watching them open at 8:00 sharp....fun at a cocktail party!
