Prunus spp.
Midsummer, dull red skin, golden yellow flesh.

MN 91 [(P. sim. × P. sal. Shiro) × P. a. Wyant] U Minn, 1921.

Large 2" dull red fruit. Firm sweet juicy golden-yellow semi-freestone flesh, very good for eating and cooking. Long picking season. Blooms earlier and longer than most hybrids and appears to be a very good pollinator for other hybrid plums, including Purple Heart. Northern Maine grower Steve Miller considers it one of his most reliable bearers. Long ripening season. Vigorous large spreading tree. Z3. (3–6' bare-root trees) Limited supply—order early!

Additional Information

Hybrid Plums Prunus spp.

Extremely hardy crosses between various Asian and American species; may fruit even after severe winters.

Hybrid plum fruiting can be inconsistent but it’s worth the trouble! Warmer areas will see longer bloom times. Cold late springs may force blooming all at once. Both of these conditions can be optimal for plum crops. At other times, it can be a little hit or miss. Bloom times are similar for all the varieties we offer.

Hybrid plums are less susceptible to black knot than European plums and have few issues other than Japanese beetle and plum curculio attraction.

At maturity, hybrid plums are roughly 15–20' tall.

Growing Hybrid Plums

  • Soil: Prefers well-drained fertile soil.
  • Sun: Full.
  • Pollination: Requires a second variety. We recommend planting at least 4 different varieties close together. Including an American Plum Seedling in your grove can help ensure pollination.
  • Planting: See our planning and planting and pests and diseases pages for more information about soil prep, planting, and pest control.
  • Spacing: 15–20' apart, or closer for a thicket.
