🌸 Krauter Vesuvius Cherry Plum

What it looks like

Why this variety

Krauter Vesuvius is the purple-leaf plum that landscape designers reach for when they want burgundy foliage that actually holds its color through summer. The leaves emerge dark red and deepen to a dark purple, nearly black in full sun, and the tree carries light pink spring flowers before the foliage fully takes over. It is upright and narrower than many purple-leaf plums, which makes it the choice for side yards and streets where a spreading tree would be a problem.

The fruit is the honest footnote: small, cherry-sized plums, edible and popular with birds, produced in modest amounts — Krauter Vesuvius is notably less messy than fruit-heavy selections, which is a feature if you hate stained sidewalks. Grow it as an ornamental tree that happens to fruit, not as an orchard tree that happens to be purple, and you will never be disappointed by the crop.

Deep, dark purple foliage all season; upright habit 15-20 feet tall. Light pink flowers; small, modest fruit crops — the tidy purple-leaf pick.

How to grow

Plant in full sun — shade turns purple foliage green, which defeats the entire purpose — in well-drained soil. Prune after flowering to shape, and watch for black knot and other stone-fruit problems; remove any swollen black growths promptly and dispose of them off-site.

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: purple-leaf plums are cool-to-warm climate trees, and Krauter Vesuvius is a North Florida trial only. Its foliage color holds better with some chill and cooler nights, and Florida heat, humidity, and stone-fruit disease pressure work against both color and health. In North Florida, plant in full sun with airflow and well-drained soil; further south, expect foliage to fade and the tree to struggle. This is an ornamental trial, not a fruit-crop promise.

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.

Saving seeds

Krauter Vesuvius is the purple-leaf plum that landscape designers reach for when they want burgundy foliage that actually holds its color through summer, and it is planted grafted — plant grafted trees while dormant in late winter or early spring, in full sun and deep, well-drained soil, and keep the graft union above soil level. The Propagation section of the Cherry Plum guide covers propagation for the species.
