Do Plums Have Seeds Inside?

Plums on a rustic wood background.

Plums are a stone fruit of a medium size. The most common kind has a deep purple skin with yellow meat inside, but green-yellow plums are also available. The fruit has a stone in the Centre that is not edible in all kinds. Prunes are plums that have been dried.

Varieties of Plums

Plums were among the first fruits that humans cultivated, giving us thousands of years to develop new plum types. There are far too many to name here, but some of the more common types you might encounter include:

  • Blackamber: One of the most well-known. The outside is dark purple, while the inside is pale yellow.
  • Damson: A purple-skinned fruit with a tarter flavor that’s perfect for jams and baking.
  • Greenage (or Reine Claude): This little, vivid greenish-yellow cultivar is extremely tasty, though it can be difficult to find.
  • Mirabelle: These are little, yellow, and quite sweet.
  • Satsuma: A reddish-brown skin with a vivid scarlet interior.
  • Prunes (dried plums): Prunes (dried plums) are manufactured from freestone plum types (the seed is easily removed, as opposed to clingstone varieties). And what about their well-known laxative effects? That’s because they’re high in fiber and sugar alcohol sorbitol.

Do Plums Have Seeds Inside?

Plums, like peaches, apricots, nectarines, pluots, and cherries, are stone fruits. All of these fruits have a single pit in their center. Although pits contain seeds, the two are not the same.

Both structures are involved in fruit tree reproduction, albeit most fruit tree reproduction is done through cuts and grafting rather than pit or seed germination. Most market types allow for seed harvesting, which is followed by a procedure known as “stratification.” The seed can be sown outdoors or in a container once it has germinated.

Seeds are the plant’s ovules, each of which includes an embryo. The fertilized section of the flower is called the embryo, and it expands during germination to produce an above-ground stalk and a below-ground root system when planted. Pits are larger structures that house a single or more seeds. While a pit might contain more than one seed, all pit-containing fruits only have one pit.

Are Plum Pits Edible?

The entire pit of a plum tree is usually too huge and indigestible to eat with a hard outer coating. Cracking the outer shell reveals a little embryo inside. This is the portion of the pit that, when planted, grows into a new tree and is tender enough to eat.

All stone fruit pits, on the other hand, contain hydrogen cyanide in the form of amygdalin, a chemical molecule. Although hydrogen cyanide is toxic, the amount contained in a single pit is insignificant. Nonetheless, plum pits should not be consumed.

Types of Pits in Plums

Plums, like peaches and nectarines, exist in both cling and freestone varieties. Cling types have skin that clings to the pit tenaciously, whereas freestones have flesh that easily peels away from the stone. Because it is easier to remove the pit from freestone plums and other stone fruit, they are easier to prepare for jams, jellies, and pies than clingstone kinds. These types are juicy and sweet, but they’re also solid, making them simple to chop or slice.

Clingstone fruits are often larger than freestone kinds, and when processing or consuming the fruit, part of the luscious meat is wasted. Clingstone types are ideal for sauces because of their increased juiciness, and they are always good to eat raw. There are also semi-freestone variants that have a mix of freestone and clingstone properties.

How to Plant a Plum Seed

Each plum pit has the ability to sprout into a new tree. Plum trees germinate and sprout rapidly from seed, but they require a period of cooling, known as stratification. Although the process takes a significant amount of time, your hard work will be rewarded in spring when you get a tree seedling.

However, because stone fruit trees rarely reproduce well from seed, establishing a plum tree from seed may not result in a tree with good-quality fruit.

Growing Plums from Pits

To germinate, a plum pit or seed requires intense sunshine and a warm temperature. After all threat of frost has passed, sow the seeds in the spring. For germination stratified plum seeds, an 8-inch nursery container with seed-starting compost works well. Make sure the container has holes below. Sow one plum seed at a depth of two inches (6 cm) in the container. Set the container outside in a bright location with shelter.

To germinate plum seeds, researchers recommend temperatures of roughly 86°F during the day and around 68°F at night. To encourage germination, warm the container with a heating coil. Maintain wet but not damp soil. It can take many months for a new, stratified plum pit to germinate, but you can start looking for sprouts after one month.

Final Thoughts

Stone fruits pits, including mangoes, nectarines, peaches, plums, and cherries, comprise cyanide compounds that are poisonous. If a fruit pit is accidentally swallowed, it might not cause major harm. However, the seeds should not be crushed or chewed.

Plums contain pits which isn’t the same thing as seeds. Seeds are smaller in size, and there can be many inside a fruit. But plums generally contain one pit that contains seeds. You can grow plums from pits. To do that, follow the guidance provided above.
