# Smooth Phlox (*phlox glaberrima*) Smooth Phlox (Phlox glaberrima) is a vibrant and cherished wildflower native to the eastern and central United States. Renowned for its brilliant clusters of pink to purple flowers, it brings a splash of color to meadows, open woodlands, and prairies during the summer months. This perennial herb is an important component of its ecosystem, providing nectar for various pollinators and contributing to the aesthetic beauty of natural landscapes. Its relatively easy cultivation has also made it a popular choice for native plant gardens, where it thrives and adds a delicate elegance with minimal care. - **Category:** [Plants](https://www.snappit.app/explore/categories/plant) - **Rarity:** Common - **Danger:** 1/5 · Very low - **Snaps:** 1 - **Habitat:** Smooth Phlox is typically found in moist to wet prairies, open woods, meadows, stream banks, and savannas. ![Smooth Phlox](https://inaturalist-open-data.s3.amazonaws.com/photos/148305451/medium.jpg) Photo: Carol Ann McCormick, CC BY 4.0 · [iNaturalist](https://www.inaturalist.org/photos/148305451) ## Appearance Smooth Phlox typically grows 30-90 cm (1-3 feet) tall, featuring slender, unbranched stems that are, as its name suggests, smooth and hairless. The leaves are opposite, lance-shaped, and also smooth, contributing to its sleek appearance. The star-like flowers, measuring about 2-3 cm across, bloom in dense, rounded clusters at the top of the stems. Petal color ranges from bright pink to magenta or lavender-purple, often with a darker eye, creating a striking visual contrast against its green foliage. ## Taxonomy - **Kingdom:** Plantae - **Phylum:** Tracheophyta - **Class:** Magnoliopsida - **Order:** Ericales - **Family:** Polemoniaceae - **Genus:** Phlox ## Interesting facts - Historically, some Native American tribes used certain Phlox species for medicinal purposes, though specific uses for P. glaberrima are less documented. - It is a valuable native plant for rain gardens and moist border plantings, supporting local biodiversity and requiring minimal maintenance once established. - Smooth Phlox is distinguished from other Phlox species by its consistently hairless (glabrous) stems and leaves, a key identifier reflected in its scientific name 'glaberrima'. - The genus name 'Phlox' comes from the Greek word for 'flame,' possibly referring to the intense colors of some species or their brilliant mass blooming effect. ## Special abilities - **Pollinator Magnet:** Its brightly colored, fragrant flowers act as a strong attractant for various pollinators, especially butterflies and long-tongued bees, facilitating efficient cross-pollination. - **Moisture Tolerance:** Adapted to thrive in consistently moist to wet soil conditions, allowing it to flourish in habitats like wet prairies and stream banks where many other plants might struggle. - **Self-Seeding Prolificacy:** Produces numerous seeds that readily self-sow, enabling it to establish and spread naturally within suitable environments, ensuring its persistence in the landscape. ## Measurements & details - **Length:** 30-90 cm - **Weight:** 0.01-0.1 kg - **Lifespan:** 3-10 years - **Clutch Size:** 50-500 ## Diet & Feeding As an autotrophic plant, Phlox glaberrima produces its own food through photosynthesis, converting sunlight, carbon dioxide, and water into sugars for energy and growth, while absorbing essential minerals from the soil. - **Primary Foods:** Sunlight, Carbon Dioxide, Water, Nitrogen, Phosphorus, Potassium - **Foraging Method:** Photosynthesis, Nutrient Absorption ## Ecological connections - **Mutualism:** [Eastern Tiger Swallowtail](https://www.snappit.app/explore/eastern-tiger-swallowtail) (*Papilio glaucus*) — Nectar source for adult butterflies. - **Mutualism:** [Bumblebee](https://www.snappit.app/explore/bumblebee) (*Bombus spp.*) — Nectar and pollen source for long-tongued bees. - **Eaten by:** [White-tailed Deer](https://www.snappit.app/explore/white-tailed-deer) (*Odocoileus virginianus*) — Leaves and stems may be browsed. - **Mutualism:** [Mycorrhizal Fungi](https://www.snappit.app/explore/mycorrhizal-fungi) (*Glomeromycota spp.*) — Forms symbiotic relationships with fungi to enhance nutrient uptake. ## Safety **Danger:** 1/5 · Very low No special safety notes yet. ## Frequently Asked Questions ### How to identify Smooth Phlox? Start with the whole plant, then compare leaf arrangement, leaf edges, stems and any flowers or fruit. Opposite leaves grow in pairs; alternate leaves come one at a time along the stem. These details tell you far more together than a single green leaf does.
