    Whats the average yearly growth rate? I can only find 'slow' on t'internet..
    I've fallen in love with these a bit, since @Dovefromabove suggested them to replace a tree. They have some in a local garden centre, but the trees are only about a foot tall, so if they grow too slowly for my patience rating, I'll have to get a bigger one.
    TIA.

    They are very slow...my one in a pot has been five years and barely has increased size by 20cm. I can imagine larger specimens will be hugely expensive because of their slow growth.

    If you wanted a more columnar variety I'd heartily recommend Prunus Amanogawa in the same time in the ground it has doubled in size and the spring blossom is wonderful and some lovely autumn colour.

      @amancalledgeorge that's very slow, I wonder if planted ones would be a bit faster??
      Thanks for the recommendation, if it's suitable I know I'll end up getting both. :biggrin:

      @amancalledgeorge those trees are beautiful, but I don't think I could have one - apparently the flowers can get stripped by strong winds - we're ¾ of the way down a hill, and the wind comes off it straight down the road. We're in one of those daft roads where nobody was allowed fences or hedges, so it's all open.
      Shame that.

      I haven't found the flowers to be that figutive but also we are not up a hill. Wonder if a Cersis or an Amelanchier would do better in your conditions. I'll be on a similar position in our next garden as we have to remove a massive badly planted conifer and will be looking for an ornamental specimen tree for a bit more exposed location than my current inner city plot.

        Yes there are a few trees with blossom dotted about up the road, but all small ones, and nothing tall & slim. Our horrid crab apple that's hopefully going soon doesn't have any problems either. Maybe I'm being overly cautious..
        I've got a couple in mind now, and amelanchier are a bit too big - I do like them though.

        My kojo-no-mai is about 10 year old. It was 30-40cm when bought, and moved once after planting, so had to settle twice. It's now about 210cm tall. The growth rate is not excessively slow (assuming it settles well and is happy in its spot). I recommend getting a small one and enjoy seeing it grow, as larger trees tend to be more pot bound and take longer to settle. I would pull it up a bit in the pot before buying to check the root system is not completely congested. I like the tree a lot as it slowly fills out a space without weird shoots going off - that said, I do occasionally prune it lightly, mostly to remove crossing and rubbing twigs or branches. At this stage I wonder how old it can get in good health.

          Thanks @micearguers. I will end up with one quite soon I think.

            There is a type of Amelanchier I have planted that is more shrub like and stays about 2metres in height - Amelanchier spicata.

            Can't be very precise about the growth rate of Prunus Kojo No Mai but I think the one I have growing has gone to about 2metres after about five years after being planted at about 30cm. I think the growth has been a bit faster as it has got more settled in but I think I read they don't get much bigger than the 2 metres it is at now.

            Happy gardening!

              They grow faster than I thought then. It's not so much my impatience going on here, I can't help thinking more flowers = more for the bees, as we're removing a 20ft apple, but it doesn't matter, I'll just replace it with two (or three..). :smile:

                Mine is in a pot and hardly grows at all but I'm planting it in the ground this year so it will start growing again I hope, and then I'll get more flowers on it.

                  Don't be shy about posting a couple of photos of your little tree will you? :biggrin:

                    @Macraignil the Amelanchier Spicata is really pretty, I'll keep it on the back burner. :smile:

                      It's rather shapeless, so as it grows I hope to prune it a bit so that it looks nicer.

                        Our Kojo is about 12 years old. It seems to be quite happy in the ground and we don't feed it and it's about 6ft high.
