## Notes

Hortulan plum is a wild plum of the central states, from southern Ohio, Indiana and Illinois west to Iowa, Nebraska and eastern Kansas, and south to Tennessee, northern Arkansas and Oklahoma. It grows as a small tree and rarely suckers, unlike our American and Chickasaw plums, which form thickets. It was once thought a cross of those two, but botanists now treat it as a species of its own. Its garden varieties, known as the Wayland or hortulana plums, were grown for fruit in the Mississippi Valley and the South. NatureServe ranks it critically imperiled in Iowa, Kansas and Nebraska. Plant it at the edge of a yard or along a creek, where you want one fruiting plum rather than a thicket.

## Size, growth and what to expect

No source rates its growth, so our growth estimator treats it as a medium grower, like our Mexican plum, about a foot and a half a year. It makes a small tree of 20 to 30 feet, sometimes a shrub, with moderately thorny branches.

White flowers up to an inch across open in clusters of two to four in April and May, before or as the leaves emerge. The plums ripen in August and September, about an inch across, red to yellow with small white dots and little bloom. Birds and mammals eat wild plums, and rodents eat the pits.

It grows wild in prairies, on stream banks, floodplains and pond margins, and at woodland edges, fencerows and old fields. Records from Maryland, Massachusetts, Texas, Virginia and West Virginia lie outside its native range.

## How to grow Hortulan Plum

Hortulan plum grows in full sun or part shade. In the wild it grows on stream banks, floodplains, pond margins and woodland edges, so give it a soil that stays moist but drains. Plant it 15 feet from a wall and at least 15 feet from overhead wires, and set trees 20 feet apart.

Saplings ship bare-root or potted. Plant them dormant, from leaf fall until bud swell, in a hole wider than the roots and no deeper. Set the root flare at the soil line, put the native soil back in, and keep the mulch clear of the trunk. Sow the cleaned pits outdoors in early fall, an inch deep, under hardware cloth against mice. For spring, hold them damp in the refrigerator for about three months first.

Water weekly through the first summer, then only in a long drought. Deer browse the twigs of wild plums, so guard each young tree with wire for its first two or three years. Prune in late winter, only to remove dead, broken or crossing branches.

Plums need pollen from a second plum to set fruit, so plant two or more from different seed. Seedlings can bear from about their third year.
