They are all varieties of the same hybrid, Prunus x subhirtella , the autumn or winter flowering cherry
. Prunus is the generic name for plums, cherries, peaches and nectarines, and applies whether they are varieties grown for fruit or the extensive range which have been bred as ornamentals.
WINTER FLOWERING CHERRY
: PRUNUS X SUBHIRTELLA AUTUMNALIS I was delighted to see this tree flowering in my neighbour's garden this week.
There are three large flower beds there full of roses, perrenial and annual flowers, two silver birch and two winter flowering cherry
trees, plus other trees, and in winter the borders are full of narcissus and daffodils.
AS SOON as the leaves fall in my garden, the first flower on my winter flowering Cherry
begins to break into blossom.
You could also try the winter flowering cherry
Prunus subhirtella autumnalis which is available in white and pink.
