I think this is a Sedum which is just coming into flower; I brought a small piece from the UK and it is now growing really well.
The medlar fruits; sadly we will not be here when they are ready, as they need a first frost before picking.
Medlar fruit are very hard and acidic. They become edible after being softened ("bletted") by frost, or naturally in storage, given sufficient time. Once softening begins, the skin rapidly takes a wrinkled texture and turns dark brown, and the inside reduces to a consistency and flavour reminiscent of apple sauce. They can then be eaten raw, often consumed with cheese as a dessert, although they are also used to make medlar jelly and wine. Another dish is "medlar cheese", which is similar to lemon curd, being made with the fruit pulp, eggs, and butter. http://en.wikipedia.org/wiki/Mespilus
