Unknown scented tree

[Gerdk]

I just presented the following pics at the end of a sequel of photos from the 'Flora', Cologne.

This is a treelike shrub of  a height of about 4 m. It seems it is evergreen and the flowers are
scented.
I would like to know what species it is. Any help welcome!

Could it be Trochodendron aralioides?

I don't think so, John. Gerd's pix show petals on the flowers....and they are very white.

[johnw]

Quite right Maggi. I found a pic of the Troch flowers.

Yes, those are like little broccoli heads, aren't they?

Gerd,

I think it is a viburnum (Snowball). From the pictures you show it must be V. henryi.

[Maggi Young]

Yes, Uli,you have it there......

Uli, I take my hat off to you! It is indeed an evergreen snowball - great to have specialists
here for all kind of plants!

Gerd,

the snowballs are one of the four to five woody genus I'm very intrested. My first V. henryi I saw in the Rombergpark of Dortmund. Hope to visit the Flora in August.

Uli.... and all you other clever persons.......
another unknown scented schrub for you to help name,  please  

This was grown  from seed collected outside a hotel in Portugal..... though of course it may not be Portuguese!
It smells like a lovely Daphne, but it has five sepals  which are not connected at the base; it  looks a bit like a Drimys or Pseudwintera, but we don't really think it is one of those, either   :-\Can it be another Viburnum?  
Hope you can help!  The flower scent is delightful, almost like orange blossom, leaves evergreen, with a "don't eat me smell" when crushed.
click the pix to enlarge.....

A Pittosporum perhaps? Is it fully hardy for you outside?

[Maggi Young]

It's not mine: just given the sprig you see in the vase to identify. Survived a few winters in Scotland  so far.... so more hardy than some of the possiblities I've considered so far!!

The leaves are more substantial than most Pittosporum I know... more leathery, somehow.
Do Pittosporum have scented flowers? (I don't think I have ever seen the varieties that grow in gardens around here actually make flowers... perhaps too cold for them? Those types are manily the variegated sort with spoon-shaped leaves))

[Maggi Young]

Ian and I both studying the twig now....  Arisaema, you have got it exactly right!
Perhaps Pittosporum tobira?
It is not a plant which I have seen grown around here. Thanks!!  Marvelous what can be found outside holiday hotels, isn't it  ? !

Maggi,

I grow two Pittosporum tobira here, a normal  one and a small sized one, smaller leaves, growth etc. It's not a shrub I stop by to smell but it is a good green background filler.

Thanks for that, Paddy. The scent on this one is really fantastic.... I would think you would catch a whiff on the air and then seek out the source. Might this P. tobira be a correct "spy" , then?
