It is a genus which includes about fifteen species of terrestrial orchids, with deciduous leaves, spread in Australia, New Zealand and Indonesia; they have big tuberous roots, which tend, with the time, to produce several shoots with new plants; each tuber produces a single leaf, semi-erect, elongated, of grey-green colour, in many species rather fleshy.
In spring and summer, from each tuber, stands a stem carrying single flowers, or, more often, united in long panicles, 40-50 cm tall, carrying 10-20 flowers, usually blue or violet, but also red, yellow or white. In most species, the labellum is quite similar to the other petals. Orchids not easy to find, very diffused, however, in the area of origin and with very particular colours.
Place the Thelymitra orchids in a very bright, even sunny, position; the thelymitra are called sun orchids, as their flowers bloom only on bright, sunny days, while they close at night or in the presence of clouds when the sunlight disappears.
These orchids can bear minimum temperatures close to 4-5°C, in areas with harsh winters it is therefore best to keep the tubers in cold greenhouses; with the arrival of cold autumns the aerial part dries completely, if we live in areas with not very cold winters we can simply protect these plants with a good mulch of the ground.

As far as watering is concerned, water Thelymitra orchids regularly, avoiding stagnation in the saucer and allowing the soil to dry up well between one watering and the other to avoid the formation of root rot; from March to September provide specific fertilizer for orchids every 10-15 days, mixed with water from the watering to ensure optimal growth. It is advisable to reduce the amount of fertilizer to be administered to the plant compared to what is written on the package.
A little product is enough to significantly improve the growth of the orchid.
Soil is a fundamental element to be taken into account for the growth of our plants. Thanks to the soil, our orchids can acquire the nutrients they need to grow. For this reason, the choice of soil must be weighed and made according to the specific needs of our plants. As far as the soil is concerned, therefore, use a good balanced universal soil, rich in organic matter, lightened with a few pieces of bark and with a minimum amount of sand or perlite.
The tubers tend to widen, therefore the specimens cultivated in pot are to be repotted every 2-3 years, in order to give the roots sufficient space for the development.
The multiplication of this orchid usually takes place by seed; in autumn it is also possible to divide the tubers, taking care to leave some well developed roots for each portion practiced.
