Fragaria virginiana
Fragaria virginiana, known as Virginia strawberry, wild strawberry, common strawberry, or mountain strawberry, is a perennial North American strawberry that grows across much of the United States and southern Canada. It is one of the two species of wild strawberry that were hybridized to create the modern domesticated garden strawberry (Fragaria × ananassa).
Fragaria virginiana can grow up to 10 centimetres (4 inches) tall. The plant typically bears numerous trifoliate leaves that are green on top, pale green on the lower surface. Each leaflet is about 10 cm (4 in) long and 4 cm (1.6 in) wide. The leaflet is oval shaped and has coarse teeth along the edge except near the bottom. This plant has a five-petaled white flower with numerous pistils, surrounded by yellow-anthered stamens. There are ten small green sepals under the petals.
The seeds of this plant are developed from the pistils in the centre of the flower which will become dark-coloured fruit (achenes) on the strawberry. The fruit of the wild strawberry is smaller than that of the garden strawberry (Fragaria × ananassa). Botanically, the fruit is classified as an aggregate accessory fruit, but it is commonly called a berry. Strawberries reproduce both sexually by seed, and asexually by runners (stolons).
Fragaria virginiana thrives best in moderate to cooler temperature climates. Full sunlight or partial shade are ideal for the plant, and nutrient dense well-drained soils (ideally sandy loam). The wild strawberry is native to North America, and is found in all US states and provinces of Canada.
All strawberries have a base haploid count of 7 chromosomes. Fragaria virginiana is octoploid, having eight sets of these chromosomes for a total of 56. These eight sets of chromosomes pair as four distinct couples, of two different types, with little or no pairing between sets. The genome composition of the octoploid strawberry species has generally been indicated as AAA'A'BBB'B'. The A-type sets were likely contributed by diploid ancestors related to Fragaria vesca or similar species, while the B-type genomes seem to descend from a close relative of Fragaria iinumae. The exact process of hybridization and speciation which resulted in the octoploid species is still unknown, but it appears that the genome structure of both Fragaria chiloensis and Fragaria virginiana (and by extension their hybrid, the cultivated octoploid garden strawberry as well) are identical.
As stated prior, Strawberries reproduce both sexually by seed, and asexually by runners (stolons). This is reflected in the composition of gynodioecious Fragaria virginiana populations. Having both bisexual and female plants within a population creates room to have a variety of reproductive strategies.
The stolons in asexual reproduction result in a creeping spread of the Fragaria virginiana population. This results in the dispersion of the plant being relatively clumped and nearby the parental plant, taking root close to the established population.
When reproducing sexually, the strawberries require pollinators to take the pollen from one plants anthers to another plants stigma. Interestingly, these pollinators (often bees, flies and ants) have been found to have a preference for visiting the hermaphrodite flowers over the female flowers.
