Physical Characteristics
 icon of manicon of flower
Arabidopsis thaliana is a ANNUAL/BIENNIAL growing to 0.5 m (1ft 8in). It is in flower from Apr to May. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects, self.The plant is self-fertile.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers dry or moist soil.

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.


The plant is used to cure sores in the mouth[240].


Other Uses
Widely used for studying plant sciences, including genetics, evolution, population genetics, and plant development. Although A. thaliana has little direct significance for agriculture, it has several traits that make it a useful model for understanding the genetic, cellular, and molecular biology of flowering plants.
Cultivation details
We have no specific information on the cultivation needs of this species. It will probably grow best in a reasonably sunny position, tolerating dry and poor soils. Please see the plants native habitat for further ideas on its cultivation needs[K].
Seed - sow spring in situ.

It should be noted that this plant is very widely used in botanical research.

I agree with Donald. The 'Other Uses' section should be updated and include a discussion of the fact that this is the lab-rat of the plant sciences. The entire genome has been sequenced which has allowed for genetic, molecular, and biochemical studies. The Arabidopsis genome has been used as a reference point for other plants whose genomes have yet to be sequenced. The small size of the genome, short lifespan, and ease of growth of Arabidopsis makes it a good plant to use for general botanical research.
