See it on our plum disease chart (opens in a new tab)At a glance: Florence Plum Seedling is a plum tree rated hardy to zone 3b in our ratings (winters to -35°F), and not self-fertile, so it needs a different variety nearby as a pollenizer (bloom group 4 of 7, mid for a European plum).

| Chill hours | About 800 hours (600 to 1,100). Seedlings vary, so this is based on the parent tree. Montana winters give it plenty. In milder climates, make sure your winters average at least this much. Check your chill hours or see our sources. |

Overview
Florence Plum Seedling refers to seedlings grown from a purple, freestone European plum discovered by Luke Ruffner in Florence, Montana. The original mother tree was almost certainly grown from seed and was therefore not a named cultivar. These seedlings represent open-pollinated genetic material derived from that original tree and are valued for their hardiness, precocity, and regional adaptation.
Fruit Quality & Uses
In terms of fresh flavor, Florence Plum Seedling fruit is astringent and not especially pleasant when eaten directly off the tree, even at full ripeness. However, when fruit is harvested ripe and allowed to rest in a cool location for one to two weeks, the flavor improves significantly. After this conditioning period, the plums become reasonably good for fresh eating and perform especially well when cooked, making excellent plum compote or plum jam.
Growth Habit & Spacing
The trees exhibit a very upright growth habit. Because of this narrow form, seedlings can be planted as close as 10 feet apart, though 15 feet of spacing may allow for easier management, better light penetration, and long-term structure. These seedlings respond well to training and can be shaped effectively through pruning.
Precocity
Florence Plum Seedlings are notably precocious. The photo shown is of the original mother tree, and the seedlings offered were grown from seed collected from that fruit. Early bearing has been observed, making these trees productive at a young age relative to many European plums.
Cold Hardiness & Genetic Value
Based on long-term observation, the original mother tree has been established since the 1980s, during which time the Florence area experienced winter temperatures into the mid −30°F range. This suggests that the mother tree is hardy to at least −35°F and possibly capable of surviving temperatures approaching −40°F under favorable conditions. These seedlings are best considered a Zone 3b plum. While not a refined dessert variety, they possess meaningful genetic value for cold hardiness, resilience, and adaptation to northern continental climates, making them worthwhile material for propagation and further selection.
Questions we get about Florence Plum Seedling
Does Florence Plum Seedling need a pollenizer?
Yes. Florence Plum Seedling needs pollen from a different variety that blooms at about the same time. Self-fertility of these seedlings is unknown, so plant another European plum such as Stanley or Mount Royal nearby. Japanese and hybrid plums (Toka, Superior, La Crescent, Ptitsin #5 and the like) cannot pollenize it. Partners we carry include Stanley Plum, Mount Royal Plum, Italian Plum.
How cold hardy is Florence Plum Seedling?
We rate Florence Plum Seedling hardy to zone 3b, which means winters down to about -35°F. Our ratings come from real winters at our two Montana sites and from trusted growers across the North, not from a catalog average.
How many chill hours does Florence Plum Seedling need?
About 800 hours of winter chill (we count hours at or below 45°F), likely somewhere between 600 and 1,100. Seedlings vary, so that's based on the parent, the Florence, MT mother tree. Our chill hours guide has a calculator for your winters, and our research page lists the sources.
What is Florence Plum Seedling good for?
Our top use scores for Florence Plum Seedling are cooking and roasting (7/10), jams and jellies (7/10).
Is Florence Plum Seedling disease resistant?
We don't know yet. Nobody has published solid disease data on Florence Plum Seedling for bacterial canker, bacterial spot, black knot, brown rot, cytospora canker and plum pocket, so we list it as unknown instead of guessing. That doesn't mean it's weak. Plenty of the plants we grow have never been through formal disease trials. Our plum disease resistance chart has every rating, the notes and the sources.
Will deer eat Florence Plum Seedling?
Yes, deer love it. Protect Florence Plum Seedling with a fence or a cage, especially while it is young.
What arrives, and when does Florence Plum Seedling ship?
A dormant bare root plant, roots wrapped in moist sawdust with a vapor barrier, shipped or picked up in Missoula in spring. Sizes offered: 4-8". We guarantee our plants bud out. Stone fruits can be slow, so if one still has not budded out by August 15, write to us and we credit you for the following spring.
