PAEONIA SUFFRUTICOSA 'SHIMADAIJIN

I bought my first ever tree peony today, Paeonia suffruticosa 'Shimadaijim', at the Royal Horticultural Society garden nursery in Harlow Carr.  Although I have not yet seen the actual flower, the images on the internet and the photograph on the label is promising.  I had always thought that tree peonies were somewhat tender but apparently they are hardy.  We'll see, won't we?  How many hardy plants have I bought that have never survived the winter here high on the Pennine Mountains of West (wet) Yorkshire?   Answer: a lot!  I chose 'Shimadaijin', which means Island Minister (hardly a romantic translation), because of the depth of its colour with that golden centre.

Many 'named' tree peonies that we find in garden nurseries have been grafted onto a rootstock.  There were only a few Shimadaijin peonies to chose from and I chose the one where I liked the growth most, except that I could see that there were some shoots coming from the rootstock which I have now removed and planted separately to see what comes from them.

Paeonia suffruticosa 'Shimadaijin' - green leaves from rootstock

are different to the pinkish leaves from the grafted 'Shimadaijin'.

The label says: Paeonia suffruticosa 'Shimadaijin' is a scented, slow growing, upright deciduous shrub with large semi-double magenta, yellow-centred flowers appearing in spring and summer.  It will grow in any moist or well-drained soil in full sun or part shade, achieving a height and spread of 150cm (5ft).

When planting a tree peony it is necessary to plant with the rootstock below the soil's surface.  This is a YouTube video on planting peonies from Thompson & Morgan.   Information on planting tree peonies begins at 2:10.
