The only name I know for this plant is 'Upside Down Grass'. To propagate this plant you take off a head put it upside down in a jam jar of water and roots when they appear, grow out of the head. I assume this to be some sort reed/sedge which reproduces in water this way.
It could be Salix eleagnos but I am not sure enough to put that as an ID!
Re the ID and further to my first comment, done some further research and I am sure that this is the plant. Well that is what my wife's 'The new House Plant Expert' book seems to point to.
... a willow or a podocarp, but since it's a woody plant it's not the Cyperus.
... but Hippophae rhamnoides (sea buckthorn) is a plausible identification for the second image at least. (Vegetatively Hippophae rhamnoides can be mistaken for an osier or similar willow; the sessile pale orange berries borne densely on stems readily identify it in fruit.)
So sorry for duff info re first photo, didn't see it as a tree. The view on my tablet looked like umbrella plant.Now from the larger computer screen I must admit my mistake.
I'm not certain that is the correct identification but it looks right for Hippophae salicifolia, It is a small tree native to Bhutan, Nepal, Tibet and Northern India.
Looking at the following website (http://designersguide.hilliertrees.co.uk/shop/product/252) it seem that it is being promoted as a street tree for urban environments as well as windy and maritime sites.
