Re: Trachelospermum

Hi Cali,
 
As you can gather, I'm no expert on Trachelospermum...I just have a good book!  I am no wiser as to the real identity of my specimen which is not flowering at the moment and has broadly oval leaves but which are 6-7cm long.
 
Perhaps, the Hillier Manual is of some further help with your plant B. Three varieties of T. jasminoides are mentioned as colouring or turning red in winter.
 
To me just from my reading, the really diagnostic difference is whether the stamens are exserted ( ie extend out beyond the petals/corolla) = T asiaticum or not exserted = T jasminoides.
 
There is another clue....T asiaticum used to be called T. foetidum...  foetidum = "stinking / evil-smelling"... but scent invokes very different responses from different people.
 
regards
 
Brian

Thank you, Brian, though I'm afraid I'm still confused.  My old established one (A) has the larger leaves and flowers, which would make it the jasminoides, but that may be because the one I'm comparing it with (B)--which was bought as jasminoides-- is in a pot.  The only other difference is that B's leaves turn ruby red and fall in late autumn, whereas A stays evergreen.  As far as perfume goes... I find both pleasant with no hint of dog urine.

Greetings from the Algarve ( Blue sky and 21'C at 10.00hrs).
"The Hillier Manual of Trees and Shrubs" gives the following distinguishing features: 
 
T. asiaticum
leaves  oval 2-2.5 cm long.
flowers 2cm across, creamy-white with a buff-yellow centre, becoming yellow with age, and stamens exserted.
 
T. jasminoides
leaves narrowly oval 5-7.5 cm long
flowers 2.5cm across, white becoming cream with age
 
Now I must go out into my garden and check which species I have ...I had also just assumed it was jasminoides!
 
Boa sorte,

Can someone help me distinguish between jasminoides and asiaticum?  I have an established one of over 30 years that I always assumed was a jasminoides, until last month, in  a friend's garden in Italy I saw two different kinds, very similar except in perfume...my friend actually took exception to the perfume of the one most like mine, which she said was asiaticum, likening it to dog urine, and regretted having planted it.
Thank you
