Pear tree varieties
Spring is usually when fruit trees are available from nurseries and other sources.
European pear varieties that are fireblight resistant you might consider are Harrow Delight, Harrow Crisp, Harrow Sweet, Warren, Moonglow, Harovin Sundown (Cold Snap). Flemish Beauty is a nice pear but is somewhat susceptible to fireblight. Most of these pears require a different European pear variety as a pollen source
Good Asian pears include Korean Giant, Shinseiki (New Century), Nijisseiki (Twentieth Century).
