Title: Prunus incisa 'Kojo-no-Mai'
Post by: David Nicholson on March 14, 2011, 09:19:37 PM
We have had Prunus incisa 'Kojo-no-Mai' in a pot on the patio for 11 years and it is just coming into bloom this year. We bought it to commemorate my mum and wanted something that would be in flower on the anniversary of her death. Only lately having looked at other examplkes of the plant have we noticed that all of them have had green flower stems and the flowers calyxes were also green. Those on our plant are red (see pic below) which leads us to wonder if we really have P. incisa 'Kojo-no-Mai' or an imposter? Can anyone help please?

Picture of the whole plant, David?
From your shot it looks like 'Koju-no-Mai'. But it is better to see the whole plant.

I agree with Uli,one really needs to see the whole plant but from what you have shown the diameter of the branch looks to be too heavy for Ko-jo-no mai.The branch structure is extremely twiggy,particularly at the extremeties.

I think it is a beautiful plant and a lovely way to remember your Mum, whatever the name.

The most distinctive feature, to me atleast, is the zig-zagging of the twigs.

Mine looks the same and no longer zig zags

Just in from Homebase - their plants have green stems and calyx

Might the conditions in which the plant has been kept  influence the calyx colour?   Indoors/under cover  bleaching out the red?

It might Maggi but I've seen lots at garden centres, indoor and out, with green calyxes and stems.

As promised here's a pic, not a good one I'm afraid as it was very bright here today(for a change!), showing the whole plant.

So wet here the dogs won't go out.

Mine seems to have green stems and red calyces.  The flowers have only just started, seems to be the bottom of the plant first.
And look what was growing underneath it, just opened today  ;D

For me it is Prunus 'Koju-no-Mai'. The typical zigzag of the branches, with the red calyx.

Many thanks Uli, I'm very happy.

I saw a couple of plants in a garden centre yesterday labelled as Kojo-no-Mai with green stems and calyxes and very upright growth, there is obviously some mis-labelling going on in the trade.

David,

do you think, this is only a problem with "alpines"? When you work in a nursery, this is one of the main problems. And the correction takes time, and time, and ...
