    • Pratia

    Pratia (prat-ee-uh) is native to Asia, Australia and New Zealand. Pratia grows best in moist, fertile, well-drained soils in full sun to part shade. Preferring consistent moisture, Pratia tolerates boggy conditions and foot traffic. In optimum conditions, its creeping stems, which root as they touch soil, can spread aggressively. Pratia was recognized as a separate genus within the Campanulaceae family. Pratia is now considered synonymous with Lobelia, based on genetic evidence showing their close relationship.

    Pratia is a genus of flowering plants that was formerly recognized in the family Campanulaceae. It's native to Asia, Australia, and New Zealand. However, current taxonomy places Pratia within the genus Lobelia.

    Key points about Pratia:

    • Growth habit: Pratia species are typically low-growing, mat-forming perennials, often used as ground cover. They spread via underground runners and can also self-seed.
    • Appearance: They have small, often rounded leaves and produce a profusion of delicate, star-shaped flowers in shades of white, blue, or purple. These are followed by small, colorful berries.
    • Cultivation: Pratia prefers moist but well-drained soil and full sun to partial shade. It's relatively low-maintenance and can tolerate some foot traffic.
    • Uses: Ideal for ground cover, rock gardens, between stepping stones, in containers, or cascading over walls.
    • Caution: All parts of the plant are poisonous if ingested.

    Popular species include:

    • Pratia angulata (White Star Creeper): Features larger leaves and white or light blue flowers.
    • Pratia pedunculata (County Park): Known for its blue-violet flowers and ability to tolerate foot traffic.

    Important Note: When searching for information or purchasing plants, you may find Pratia listed under Lobelia or Isotoma, as these genera are now considered synonymous.

    • Historically: Pratia was its own genus within the Campanulaceae family (the bellflower family). This is how you might still find it in some older books or nurseries.
    • Current Understanding: Based on recent genetic research, Pratia is no longer recognized as a separate genus. It's now included within the genus Lobelia, which also belongs to the Campanulaceae family.

    Why the change?

    • Genetic Evidence: Studies have shown that Pratia species are very closely related to Lobelia species, and there aren't enough distinct differences to justify keeping them separate.
    • Simplifying Classification: Combining them under Lobelia makes the classification system more accurate and less confusing.

    What does this mean in practice?

    • Scientific Names: The scientific names of Pratia species have been updated to reflect this change. For example, Pratia angulata is now Lobelia angulata.
    • Finding Information: You might find information about these plants under both names, so it's helpful to search for both "Pratia" and "Lobelia" to get a complete picture.
    • Gardening: For gardeners, this change doesn't affect much. The plants' growth habits, care requirements, and uses remain the same.

    Key takeaway: While the name has changed, the plants themselves haven't. It's just a matter of scientific classification becoming more precise.

    The invasiveness of Pratia (now classified as Lobelia) depends on several factors, including the specific variety and your local environment. Here is a breakdown:

    Technically Not Invasive:

    • Officially, Pratia is not classified as an invasive species in most regions.

    Potentially Invasive:

    • However, Pratia is known for its fast-growing nature and tendency to spread readily through creeping stems and self-seeding.
    • In some areas, particularly with mild climates and moist soil, Pratia can become aggressive and overtake native plants, disrupting local ecosystems.

    Here is what to consider:

    • Variety: Pratia angulata (White Star Creeper) is generally considered more invasive than Pratia pedunculata (Blue Star Creeper).
    • Climate: Warm, humid climates with mild winters favor Pratia's growth and spread, increasing the risk of invasiveness.
    • Soil Conditions: Pratia thrives in moist soil, so well-drained areas are less susceptible to its invasiveness.

    By being aware of these factors and taking preventive measures, you can enjoy the beauty of Pratia in your garden while minimizing the risk of it becoming invasive.

    The best time to propagate Pratia (now classified as Lobelia) depends on the method you choose:

    Propagating by Seed:

    • Generally: You can sow Pratia seeds indoors anytime throughout the year. However, for best results, most gardeners recommend starting seeds 6-8 weeks before the last expected frost in your area. This gives the seedlings enough time to grow strong and healthy before being transplanted outdoors.
    • Warm Climates: In areas with warm winters and long growing seasons, you can also sow Pratia seeds directly outdoors in early spring after the danger of frost has passed.

    Propagating by Cuttings:

    • Spring or Summer: The ideal time for propagating Pratia by cuttings is during the active growing season, typically in spring or early summer. During this time, the plants are actively producing new growth, which roots more readily than older stems.

    Here is a quick summary table:

    Propagation Method

    Best Time

    Seeds (indoors)

    6-8 weeks before last frost

    Seeds (outdoors)

    Early spring (warm climates only)

    Cuttings

    Spring or early summer

    Remember, these are general guidelines. Success can also depend on factors like your specific climate and growing conditions. If you are unsure, it is always best to consult with local gardening experts or resources for the most accurate recommendations for your area.
