Why this variety

Plumcots are plum-apricot hybrids — roughly half and half — bred to combine plum sweetness with apricot perfume, and Flavorella is the variety that best represents the original idea. The fruit is sweet, fragrant, and juicy, with plum skin and apricot aroma, ripening in summer on a moderately vigorous tree. Their better-known descendants, pluots, lean more heavily plum, but a true plumcot is its own fruit, and Flavorella is the one to try if you want to taste what the hybrid was before it was bred further toward plum.

Like other interspecific stone fruit, Flavorella must be bought as a grafted tree — seedlings are a lottery — and it benefits from a compatible pollinizer nearby, though some plantings report partial self-fertility. Grow it like a plum: full sun, deep well-drained soil, and pruning for light and air, and thin the fruit so what remains sizes up properly.

Half plum, half apricot; sweet, fragrant, juicy fruit. Grafted trees only. Plant with a compatible plum or plumcot pollinizer for best crops.

How to grow

Plant grafted trees in full sun and deep, well-drained soil. Prune to an open vase and thin fruit to a hand’s width apart. Clean up fallen fruit promptly — brown rot overwinters in mummies, and sanitation beats spraying after the fact.

Plant grafted trees while dormant in late winter or early spring, in full sun and deep, well-drained soil. Stone fruit drowns in wet feet faster than almost any other fruit group, so drainage is the whole game: raised ground beats a hollow every time. Prune to an open vase in the first few years so light and air reach the interior wood where fruit forms, and keep the graft union above soil level.

Florida framing, stated plainly: Flavorella is a North Florida trial only. Plum-apricot hybrids carry the same vulnerabilities as their parents — chill needs, early bloom, and humidity-driven disease — and Florida’s warm winters and wet summers work against reliable cropping. North Florida, sunny, airy, well-drained, with a pollinizer, judged over several springs; further south, reference only.

Water & feeding

Water young trees deeply through their first two growing seasons, then water consistently through fruit development — uneven watering makes fruit split and drop. A thick mulch ring (kept off the trunk) holds moisture and suppresses weeds, and worm castings worked into the planting hole and as a spring top-dress feed the soil biology that stone fruit rewards. Skip heavy nitrogen after fruit set: it buys leaves at the expense of fruit.

Common problems

  • Brown rot — the classic stone-fruit fungus, worst in warm, humid weather. It rots blossoms and fruit and overwinters in mummified fruit left on tree or ground. Sanitation (remove mummies, fallen fruit, and diseased wood) matters more than any spray.
  • Bacterial canker and black knot — swollen, black growths on branches. Prune well below the swelling in dry weather and dispose of cuttings off-site; do not compost them.
  • Late frost on open bloom — one hard freeze after a warm spell ends the crop. Site trees where cold air drains away, not in frost pockets, and accept that some springs will simply be lost.
  • Birds and squirrels — they know ripeness a day before you do. Net before fruit colors fully if you want to taste the crop.
  • Peach tree borer and other borers — sawdust-like frass at the trunk base is the sign. Keep trunks healthy, avoid mower wounds, and remove infested wood.

Harvest

Pick when fruit colors fully, yields very slightly to pressure, and smells fragrant — stone fruit picked hard never develops full flavor, and fruit picked soft bruises in the basket. Taste one before harvesting the whole tree. Use fresh within days, or preserve promptly: jam, drying, freezing, and baking all suit stone fruit, and a glut handled the same week beats a glut left to rot on the tree.

Nerdy fact: The plumcot was developed in the late 19th century by Luther Burbank, the same breeder behind the Burbank potato and the Shasta daisy. Flavorella’s lineage is a reminder that interspecific hybrids are not modern novelties — gardeners have been crossing plums and apricots for well over a century.

Saving seeds

Flavorella is a true plumcot — half plum, half apricot — and like other interspecific stone fruit it must be bought as a grafted tree; seedlings are a lottery. The Saving seeds section of the Plumcot guide covers seed for the species generally.
