3.3.2.1.1. Soils and climates

Although originally native to temperate regions of the globe, roses have adapted to warmer regions and grow well now in very diversified habitats and soil types. The soil should be well drained though and not heavy. Species preference for soil type has nonetheless been reported. R. villosa was reported to grow better in a dry soil with low calcium content whereas R. canina and R. dumalis prefer more calcareous soil. R. rubiginosa also prefers more calcium and grows well in a relatively heavy soil. R. palustris grows in marshes and R. nitida in bogs. Similarly, R. virginiana likes salt marshes and salty soils (Joly, personal communications). In Prince Edwards Island province (Canada), wild rosehips are found in a variety of habitats including hedgerows, wet and dry pastures, thickets, swamps and uplands in dry orthic humo-ferric Podzol sandy soils. In hard winter climates such as Canada, plant survival rate in the field setting can vary from genotype to genotype and for the same genotype, plastic coverage has been shown to increase the winter survival rate (Figure 4).
