Calcicole

A calcicole, calciphyte or calciphile is a plant that thrives in lime rich soil.^[1][2] The word is derived from the Latin 'to dwell on chalk'. Under acidic conditions, aluminium becomes more soluble and phosphate less. As a consequence, calcicoles grown on acidic soils often develop the symptoms of aluminium toxicity, i.e. necrosis, and phosphate deficiency, i.e. anthocyanosis (reddening of the leaves) and stunting.

A plant that thrives in acid soils is known as a calcifuge.

A plant thriving on sand (which may be acidic or calcic) is termed psammophilic or arenaceous (see also arenite).

Examples of calcicole plants

• Ash trees (Fraxinus spp.)
• Honeysuckle (Lonicera)
• Buddleja
• Lilac (Syringa)
• Beet
• Clematis
• Sanguisorba minor
• Some European orchids
• Some succulent plants genera Sansevieria and Titanopsis or cacti genus Thelocactus.
• Calcicolous grasses
