Crataegus uniflora, commonly known as the dwarf hawthorn or the one-flowered, is a species of hawthorn native to North America. It belongs to the Rosaceae family, which includes many other fruit-bearing plants like apples, pears, and cherries.
Here are some key characteristics and information about Crataegus uniflora:
Appearance: Crataegus uniflora is a small deciduous shrub or tree that typically grows to a height of 1 to 4 meters (3 to 13 feet). It has simple, alternate leaves that are typically oval-shaped with serrated edges.
Flowers: As the name "one-flowered hawthorn" suggests, this species typically produces solitary white flowers with 5 petals. The flowers are typically about 1 cm (0.4 inches) in diameter and have a simple, understated beauty.
Fruits: The plant produces small, red or orange-red fruits, commonly referred to as haws. These fruits are similar to those produced by other hawthorn species and are typically around 6-9 mm in diameter.
Distribution: Crataegus uniflora is native to North America, particularly in the eastern and central parts of the continent. It can be found in a variety of habitats, including woodlands, meadows, and along streams.
Ecological Role: Like other hawthorn species, Crataegus uniflora provides food and shelter for a variety of wildlife, including birds and small mammals. The fruits are an important food source for many bird species.
Traditional Uses: Some indigenous communities in North America have historically used various parts of the one-flowered hawthorn for medicinal purposes, including treatments for digestive issues and heart-related ailments. However, it's important to note that the use of plants for medicinal purposes should be approached with caution and ideally under the guidance of a knowledgeable practitioner.
Landscape Use: Crataegus uniflora is sometimes used in landscaping for its attractive flowers and fruits. It can also be a valuable addition to wildlife gardens, as it attracts birds and pollinators.

Growing Instructions
Â
Stratification:
Crataegus species, including Crataegus uniflora, often require a period of cold stratification to break dormancy. To achieve this:
Place the seeds in a plastic bag with some damp sphagnum moss or peat moss.
Seal the bag and store it in the refrigerator for 60-90 days. This simulates winter conditions.
Prepare Seed Trays or Pots:
After stratification, you can plant the seeds. Use seed trays, small pots, or seedling trays filled with a well-draining potting mix. Make sure the containers have drainage holes.
Planting:
Sow the seeds on the surface of the soil or just barely cover them with a thin layer of soil. The seeds are usually small, so do not bury them too deep.
Watering:
Keep the soil consistently moist but not waterlogged. You can use a spray bottle to mist the soil's surface to avoid displacing the seeds.
Light and Temperature:
Place the trays or pots in a location with indirect sunlight or partial shade. Crataegus uniflora seedlings prefer cooler temperatures during germination.
Germination:
Germination may take several weeks to a few months. Be patient and keep the soil consistently moist during this period.
Transplanting:
Once the seedlings have grown to a suitable size (usually when they have several leaves and are a few inches tall), you can transplant them into larger containers or directly into your garden. Make sure to choose a location with well-draining soil and full sun to partial shade.
