Tall Perennial Ideas for Containers

Hi everybody, I am looking for some inspiration for two containers for my summerhouse decking. The decking is off the ground and has a rail around it and I would like the flowers to show above the rail.

My pot sizes are 45cm high and 35cm width (although I can get taller ones if necessary).  If possible, I would like something that flowers for a long time and keeps its foliage through the summer.

Thanks in anticipation

  • Hi

    not sure if this is ideal for containers but I am planning on planting this net years to add some height in my sunny border

    Verbena bonariensis? How much sun are we talking?

    Some of the taller lilies would fit the bill.

    If the pot is 18 inches, the railings will be about 3 feet so we are looking for:

    something which is over 2 ft tall and flowers all summer.

    Not sure if Cosmos would do well in a pot but that is one. The bigger dahlias might be another. Catmint also flowers all summer. And I had flowers on my penstemons for months.

  • Hi  Mark56, the sun is on the decking in the afternoon until sunset. 

    hogweed, yes the plant needs to be 2’ or more. I like the sound of cosmos but I was not sure if it grows well in a pot. Hubby not too keen on penstemons.    

    GardenSpurs and Fairygirl, will look at lilies and veronicastrum.

    many thanks everyone
