Conference is the most widely-grown pear variety in the UK. It crops heavily and reliably, and will grow in most situations.
It is also one of the few pear varieties to be reliably self-fertile, so you don't need another pollinator nearby. In turn it is a good pollinator for many other pears.
The skin is usually partially covered in golden-green russet.
Conference is one of the easiest pears to grow, being less fussy than some other pear varieties, tolerant of late frosts and strong-growing.
Unusually amongst pears, Conference is effectively self-fertile. However nearby pollination partners will help cropping - try Doyenne du Comice or Williams.
