Plants thriving in difficult growing locations
Tea (Camellia sinensis)
Ma Huang (Ephedra sinica)
Vervain (Verbena officinalis)
Normal garden soil is very rarely acidic, and if it is, it is a rather bad choice for vegetable patches - but all rhododendrons, azaleas, hydrangeas, magnolia and cyclamen as well as of course all types of heath grow particularly well under such soil conditions.
Alpine plants are an outstanding group of plant species, united by their extraordinary capacity to survive in harsh conditions, such as unprotected exposure to extreme weather and growing in meager habitats e.g. nutrient poor or thinly spread soils in the mountains or narrow gaps and crevices in between the rocks.
Halophytes & salt plants
Halophytes and halophiles are organisms which thrive in habitats with higher salt concentrations either in the soil, the water or in the air.
Aquatic and marsh plants
Aquatic plants are plants which are adapted to growing entirely or partly in water, as would be the case in riverbeds, swamps and marshlands.
Most plants prefer sunny locations, so very often we will find ourselves at a loss which plants to choose for shady or half-shade spots in the garden, for example beneath trees, next to imposing garden walls or hedges.
