Biology

The ground pine uses a double-flowering strategy. It can flower at any time from June to October, depending on the time of seed germination. A proportion of its seeds from any spring will germinate in autumn, but some will also germinate the next spring if protected from winter frosts. Even when suitable growing areas are prepared, the plant does not readily occupy these because it has no known mechanism for spreading, other than dispersal by rabbits, stock or human disturbance, but just fortifies itself in small colonies, rarely more than a few hundred square metres in area.
Although it is considered to be an annual plant, it occasionally behaves as a short-lived perennial. It is a non-competitive species, but the seeds can lay dormant for at least 50 years, possibly longer, and may germinate when the soil is disturbed. The species spreads very slowly, but can hang on in established sites and bloom again after some considerable time when the right conditions allow.
The plant itself contains a cocktail of unpleasant chemicals that make it very unattractive to herbivores, and most learn not to eat it. It is optimised for warm, dry environments with very narrow, thick-skinned leaves that minimise water loss from evaporation.
Conservation

The concern over the status of the ground pine has led to its inclusion on the UK Biodiversity Action Plans. In partnership with Plantlife, the wild plant conservation charity, English Nature has funded work on this species through their Species Recovery Programme.
Plantlife has mapped out all the known ground pine sites and liaised with landowners to encourage the sympathetic management of this plant. Several of the sites are Sites of Special Scientific Interest (SSSIs), and Plantlife carried out yearly surveys at the 15 sites known to hold populations. Scrub-clearance and deliberate soil disturbance by ploughing was also undertaken and this has had a positive effect on the populations of the ground pine.
A number of sites owned by Kent County Council have been managed in the same way, and further objectives are to try and recruit volunteers to manage all sites supporting the plant and conduct further research into its biology.
As a result of this work, the programme has moved into a Post Recovery phase, which declares that the species is maintaining itself - with the appropriate management and necessary ground disturbance - on a long-term basis as a viable component of its natural habitats. The natural range of the ground pine is no longer being reduced and is unlikely to be threatened in the foreseeable future.
It is now important that the populations at the various sites are maintained and secured from damage. Five further sites have been earmarked for a re-introduction programme to be completed by the year 2007.
Description
provided by Arkive
The ground pine is a small, greyish-green plant, which takes its name from its resemblance to a pine seedling. It also smells like its un-related namesake when the foliage is trampled or crushed. It bears yellow, red-dotted flowers in ones or twos up the stem and amongst the hairy, much divided three-lobed leaves.
It was a plant well known to Tudor herbalists who probably exploited the resins contained within the leaves. They also considered the ground pine and the similar cut-leaved germander, sometimes found growing nearby, to be male and female examples of the same species.
Habitat
provided by Arkive
This species likes disturbed, bare ground, preferring south-facing, dry hillsides on chalk. It occurs on the edges of cultivated fields, tracksides, and crumbling banks. It can also be found growing on areas that have been broken up by construction works.
Range
provided by Arkive
The ground pine ranges across central and southern Europe to the Mediterranean and into North Africa. In the UK it is confined to scattered sites in the South-east of England, in Hampshire, Kent and Surrey, and in the Chilterns.
Status
provided by Arkive
Classified as Vulnerable in the UK only.
Threats
provided by Arkive
The Ground Pine is a plant that is very particular in its choice of habitat. Many of its former sites are becoming inhospitable as a result of changes in agricultural practices, the encroachment of scrub and other dominant species, which inhibit germination, and increasing use of herbicide spraying.
Regular disturbance of the ground is critical, and in many cases this is not taking place, even where its seeds may be lying.

Ajuga chamaepitys
provided by wikipedia EN
Ajuga chamaepitys is a species of flowering plant of the family Lamiaceae. Popularly known as yellow bugle, chian bugle or ground-pine,[1] the plant has many of the same characteristics and properties as Ajuga reptans. A. chamaepitys can be found in Europe, the Eastern part of the Mediterranean, and North Africa.[2]
Description
Ajuga chamaepitys is a small herbaceous perennial that reaches 10–40 cm in height. The leaves have an opposite arrangement. Its flowering season is generally in late spring. Ground pine is a plant whose richness has been severely reduced by changes to downland farming. At first sight, A. chamaepitys looks like a tiny pine tree with a reddish purple four-cornered hairy stem. The leaves can get up to 4 cm long, are divided into three linear lobes, and, when crushed, have a smell similar to pine needles. Ground pine sheds its shiny black seeds close to the parent plant and the seeds can remain alive in the soil for up to 50 years.[2]
Herbal use
Ajuga chamaepitys has stimulant, diuretic and emmenagogue action and is considered by herbalists to form a good remedy for gout and rheumatism and also to be useful in female disorders. In the Levant, the plant has traditionally been used by locals as an analgesic.[3] Ground pine was a plant well known to Tudor herbalists who exploited the resins contained within the leaves. The herb was formerly regarded almost as a specific in gouty and rheumatic affections. The plant leaves were dried and reduced to powder.[4] It formed an ingredient of the once famous gout remedy, Portland Powder. It was composed of the leaves of Ajuga camaepitys, which has a slightly turpentine-like smell and a rough taste, with properties described as being similar to diluted alcohol.[2]
