I need a suitable polloinator Apple tree to go with my "Discovery". I would like it to be a crisp apple. Any ideas??
Off the cuff, no.
Basically what you need is an apple that flowers at the same time as your Discovery, that produces the required crisp apples.
I would suggest that you go on the Ken Muir (or other fruit supplier sites), to see what is available.
I'm a bit out of date regarding what new varieties are available at the moment.

I would go for a Cox
I grow mine with a fiesta, an egremont russet and a blenheim orange... and get a good crop of each. I think the fiesta is the cross pollinator for the discovery. A crisp redish apple that is slightly later to follow on from it!
;D
Cox's is a bit temperamental; Fiesta is more reliable, is in the same pollination group as discovery, and crops later so you'd have a longer season. But do check further as there are so manyapples which would do it.
It really depends where the enquirer is living. Neither cox or fiesta are suitable for the North West, as I can testify as they will be ruined by Canker.
Discovery is in pollination group B, and there are quite a few good apples in pollination group B.
