Perennial plant suggestions

Hello,
I am new to gardening and have made a flower box which is around a meter wide and long, I am looking for some colourful perennials with more flowers than foliage and ones that will not grow too high, do you have any suggestions?

Thanks!

Lucy

 

Aubretia.... covered in purple or pink flowers and indestructible!

 

Depends whether it's in full sun or shade, @Lucya2108! There are hardy geraniums to suit most conditions, which would flower after the Aubretia. Then pinks, and dwarf asters for later in the summer...

 

Aquilegia (columbine) are beautiful, robust, and give a little height to the planting above something like aubretia, alyssum, campanula or other low-growing plants.

For something this size, I'd also recommend a centerpiece of a small non-bushy shrub. My favourite would be syringa microphylla, but a hardy fuchsia or perhaps a small rose would be something to consider.

 

How about a four o'clock flower? They are bushy, fast growing and really nice to look at.

Only downside is, you need to dig them up for winter because they are not completely resistant to cold weather.
