Quince

The top of a newly purchased quince, still in a black bag and waiting for a permanent home.

Update 2015/11/24:

The hole is dug next to the useless plum tree the quince will replace, bone meal and a bit of compost at the bottom, ready to roll nearly 7 weeks after purchase.

The variety is "Portugal".

Hole waiting for the tree...

Description sounds good. I'll see what Google has to say as well later on.

Done. Now it's just a matter of time. Hope it gets enough sun.

A Bidens rutifolia is sharing the planting hole. It's a rather striking yellow flowered cluster.

Hmmm....

According to Google (add or subtract six months from dates for local conditions):

"Portugal is a well-known quince variety, capable of producing large fruits with a very good flavour when grown in the right conditions.

The fruit is ready for picking at the end of September, which is slightly earlier than most other quinces. However the fruits should be stored indoors (at room temperature) for a few weeks to ripen properly.

Portugal quinces may turn a crimson pink when cooked (depending on how ripe they were). They have a soft texture and mild flavour which makes them particularly suitable for making quince marmalade. They are generally considered the best flavoured of all quinces."

...

 "Although like all quinces Portugal is a fairly hardy tree, it needs a sheltered location to produce good quality ripe fruit. It prefers a dry climate and is not suitable for the wetter north-west of the UK - it is probably the most challenging quince variety to grow.

Whereas many quince trees have an attractive growth habit, Portugal is not the best choice for a feature tree - it is grown just for the fruit. It works well as a fan-trained tree or just simply allowed to grow up a south-facing brick wall.

Portugal is only partially self-fertile and cropping will be improved if there is a compatible pollinator nearby such as Meech's Prolific or Serbian Gold."
