Many native plums are very hardy, although fruit quality varies ('Norther' and 'Waneta' are two selections that have good-quality fruit). We list hybrid varieties with 1- to 2-inch-diameter fruit. Trees are small and bushy. Plant two varieties to ensure good fruit production.
'Hildreth', midseason. Small, but excellent quality. Developed in Wyoming.
'Opata', midseason to late. Reddish purple skin; yellow green flesh is sweet and juicy. Excellent fresh or in jams.
'Pipestone', early to midseason. Large, deep red skin with golden blush. Greenish yellow flesh is sweet and juicy. Good fresh or in jams.
'Superior', midseason. Large fruit with dark red skin; yellow flesh is juicy with sprightly flavor. Good fresh or preserved. Not quite as hardy as 'Pipestone' (above).
Other hardy plums that may be available locally include 'Assinboine' and 'Dandy'.
