About Wild Geranium
Wild Geranium (*Geranium maculatum*), also known as Spotted Cranesbill, is one of the most graceful and widely appreciated native wildflowers of eastern North American woodlands, producing clusters of delicate rosy-lavender to pale pink flowers with five rounded petals above a mound of deeply lobed, palm-shaped leaves in spring. A true cranesbill geranium (family Geraniaceae), it is completely distinct from the common 'geraniums' of window boxes and garden centers (*Pelargonium* spp.), which belong to a different genus and family entirely.
The flowers of Wild Geranium are simple and perfectly proportioned — five rounded, slightly cupped petals of rosy-lavender to lilac-pink, each with delicate, darker veining that serves as nectar guides for pollinators. The ten stamens and central pistil are clearly visible, and the flower's symmetrical, open-faced form is typical of the Geraniaceae family. After fertilization, the plant develops its characteristic fruit — a long, beak-like structure reminiscent of a crane's bill (giving the plant its common name 'Cranesbill'), which spring apart explosively at maturity to fling seeds away from the parent plant.
Wild Geranium thrives in the rich, slightly acidic soils of deciduous woodlands, along shaded woodland paths, and at the edges of forests — exactly the same habitat where Trilliums, Virginia Bluebells, and Wild Blue Phlox thrive. It blooms in April through June, forming long-lasting, reliable clumps that expand slowly over the years without becoming invasive. Unlike spring ephemerals, Wild Geranium retains its attractive, deeply cut foliage throughout the summer, providing consistent textural interest even after blooming has finished.
For the native plant gardener, Wild Geranium is one of the most versatile and reliable of all native shade perennials. It thrives in a wide range of soil conditions (from dry to moderately moist), tolerates more shade than many natives, is deer-resistant, and is completely non-toxic to pets and humans. It is an excellent 'bridge' plant in a woodland garden — blooming after spring ephemerals like Trilliums and Virginia Bluebells have faded, and providing foliage interest through summer until fall-blooming natives take over.

Floral Formula & Features
Actinomorphic, bisexual; 5 free sepals; 5 free petals; 10 free stamens; 5 fused carpels forming an explosive schizocarp (crane's-bill) with superior ovary
- Scientific Name & Classification: *Geranium maculatum* (Geraniaceae, tribe Geranieae). A true cranesbill geranium — NOT a Pelargonium. Native across eastern and central North America.
- Identification Markers: Rosy-lavender to pink 5-petaled flowers with darker veined nectar guides. Deeply palmately lobed leaves forming a mound. Long 'crane's bill' seed capsule after flowering. Height 1–2 ft.
- Floral Formula (⊕ ☿ K5 C5 A10 G(5)): Actinomorphic, bisexual, 5 free sepals, 5 free petals, 10 stamens, 5 fused carpels forming a long beaked fruit (schizocarp).
- Growing Requirements: Partial to full shade; moist, humus-rich, slightly acidic, well-draining soil. Tolerates dry shade once established. USDA Zones 3–8. Deer-resistant.
- Cultural Significance: Used medicinally by multiple Native American nations for diarrhea, hemorrhage, and toothache. Name 'Geranium' from Greek 'geranos' (crane) — for the crane's-bill seed pod.
- Safety & Toxicity: NON-TOXIC. Completely safe for cats, dogs, and humans. An excellent choice for family woodland and shade gardens with pets.
- Common Look-alikes: Often confused with cultivated Pelargonium ('garden geranium'), but Wild Geranium has deeply palmately lobed leaves and a symmetrical flower, while Pelargonium has slightly asymmetrical flowers.
- Internal Links: Perfect companion to Trillium and Virginia Bluebells in a spring woodland garden. Explore our Flower Identifier.

Frequently Asked Questions
What is Floral Formula?
A floral formula is a symbolic representation of a flower's structure using letters, numbers, and special symbols. It provides a concise way to describe the arrangement and number of floral parts.
This formula describes the flower's symmetry, sepals, petals, stamens, and carpels in a standardized format.
Formula Sequence
- Bract: Br or Ebr
- Bracteole: Brl or Ebrl
- Symmetry: % (Radial) or ⊕ (Bilateral)
- Sex: ♀ (Female), ♂ (Male), or ⚥ (Bisexual)
- Calyx/Sepal: K<number> (Free or Fused)
- Corolla/Petal: C<number> (Free or Fused)
- Androecium: A<number> (Free or Fused)
- Gynaecium: G<number> (Superior or Inferior Ovary)
Symbol Meanings
- Numbers: Indicate quantity of parts
- Parentheses (): Parts are fused together
- Plus (+): Parts in different whorls
- Underline: Superior ovary position
- Overline: Inferior ovary position
- ∞: Numerous parts (too many to count)
Understanding floral formulas helps botanists quickly identify and classify flowers based on their structural characteristics.
