The variety is called "robijn" it's a Dutch variety bred for cold climate. As far as I understand it's actually an almond/peach hybrid.
Planted in January or February 2015! Only two seasons ago!
I can find details of the company I bought them from. Ordered it through ebay lol
I'm hoping for mulberry next year! I've seen mulberry trees for sale on Internet for about 40ish pounds but they were all tiny saplings...
Then I found a two metre tall mulberry tree still with juvenile leaves for £35 in my local garden centre!
Later in summer it started growing adult leaves (the heart shaped ones).
So hopefully next year we will have almonds, mulberries and maybe quince
