Forum home The potting shed

Shrub/plant recommendation please.

I should be grateful if anyone can suggest a suitable plant for a corner of a raised bed that is bounded on two sides by wall and is south facing.  It will get more sun as the sun climbs higher over the surrounding rooftops.  Ideally I would like a plant that grows to above shed roof level but does not spread out, is hardy, is attractive to pollinators and has flowers in the purple through to pink spectrum.  I had thought of a buddleja but I haven't the room for a bushy, spready plant so I am a bit stumped.
Thank you.

    Amelanchier Obelisk meets some of your conditions, but has white flowers.
    I have one growing in a similar corner position.

    Thank you for the suggestion.  It does sound attractive but I think it may want to grow too bushy for. my small bed.

    Mine is about 4 years old. It is about 10ft tall, and no more than 2ft wide at the most.
    Obelisk is a fastigiate growing Amelanchier, not the bushy type.

    Thank you. I will certainly consider this plant.

    My Amelanchier alnifolia ‘Obelisk’ was planted back in 2014. Today it is reaches a height of 3.60 m and a spread of 1.20 m. I expect it has more or less reached its maturity height. It's quite easy to cut side branches (if needed only) but I confirm that it has a natural fastigiate habit. It has a lovely but very short flowering period in April, and an even shorter but lovely Autumn foliage. More pics on my garden site here.

    Thank you for the photos but my small bed is I think too small for this tree. Thank you for the suggestion.
