A ground cover they like is Virginia strawberry (Fragaria virginiana
Utilizing wild Fragaria virginiana
in strawberry cultivar development: Ineritance of photoperiod sensitivity, fruit size, gender, female fertility and diseases resistance.
First the very hardy (http://www.wildflower.org/plants/result.php?id_plant=FRVI) Virginia strawberry (Fragaria Virginiana
), a native of North America, reached Europe in the 17th century.
Thirteen native plant species were identified as having the highest constancy and cover: Achillea millefolium; Allium spp.; Anaphalis margaritacea; Epilobium brachycarpum; Eriogonum spp.; Fragaria virginiana
; Lupinus spp.; Poa pratensis; Poa secunda; Polygonum douglassi; Potentilla gracilis; Pseudoroegneria spicata; and Sedum stenopetalum.
However, the breeding of the 'new' fruit actually originated in the 18th century as the result of crossing different wild strawberries, Fragaria Chiloensis and Fragaria Virginiana
produced Fragaria Ananassa, the base for all modern varieties.
These included perennials such as Fragaria virginiana
, Parthenocissus quinquefolia, Carex cephalophora, and Vitis vulpina (C = 2-3) and a few species with C = 4 (Table 1).
Morphological variation in fragaria virginiana
from the rocky mountains.
For example, females reared on plum Prunus americana Marsh., orange Citrus sinensis (L.), and strawberry Fragaria virginiana
Miller produced 1019.2, 833.3, and 494.5 of eggs/female, respectively, and net reproductive rate (Ro) was 167.1, 83.9, and 49.2 eggs, respectively, (Krainacker et al.
For spotted knapweed transects, the five plant taxa with the highest frequency, excluding spotted knapweed, were Carex spp., Fragaria virginiana
Additionally, relatively tall exotic grasses reduce the abundance of strawberry flowers (Fragaria virginiana
), the primary food resource for adult Taylor's checkerspot butterflies (Severns and Warren 2008).
