suitable fast growing/flowering shrub bush

Hi can anyone suggest a cheap fast growing flowering shrub bush?
It is to plant behind our fence(there is a railway line there about 20ft away) to add a bit more privacy Butterfly bush has come to mind ,my wife is not to keen on conifers, so any suggestions for a cheap but tough flowering shrub bush that grows to about 6-7ft I dont mind trimming to keep in check
Thanks

 

As you suggested, Buddleia...and its proximity to the railway line will be quite appropriate:D

 

Buddleia is best if cut down to about 2' every February, so you won't have much "top" until mid summer. You could leave it to grow taller though, but I don't think it will perform as well.

 

I think Eleagnus grows quite vigorously, well suited if you use buddleia too.

Perhaps you could plant a line of willow whips as well and coppice them.

 

boring but does the job - fast growing, evergreeb and flowers for about 4/6 months during the winter - Viburnum tinus Eve Price

Photina Red Robin - evergreen and new leaves are red, trim twice a year.

Forsythia - trim after flowering

Golden leaf privet - surprising good all year round

Lilac

Elderberry - can get yellow and black leave varieties

Philadelpus - get the taller varities

Leycesteria - loved by the birds

 

What about a laurel, (Prunus laurocerasus 'Rotundifolia') which will give a green background to what you have in the garden. It also has a white flower if left to grow, and will tolerate a severe hack back to stumps if required.

Hope this Helps!

 

Why not a griselina - variegated type. relatively quick to grow and makes a good hedge

Or
escallonia
Choysia
Hope this helps
