Flowering Shrub Ideas

[megfitz]

I have a South east facing shady border on chalk, unfortunately it is backed by next doors 4 Leylandii trees, so is rather dry, In spring it has Bluebells,Cowslips and Primroses, now I have Welsh poppies, bearded iris and Campanula Pyramidalis.
I would like to take these out and replace with flowering shrubs, or herbaceous perennials that flower.
Any recommendations of suggestions please.
Thanks.

Have a play with this, Megfitz:

(You don't have to complete all of the fields; just use the ones that are important to you).

Mahonia aquifolia or Forsythia, perhaps

I second mahonia and would add daphnia....
