Tillandsia exserta
Tillandsia exserta is a rarer, attractive species from the genus Tillandsia, originally found in Mexico and parts of Central America. It grows epiphytically on trees in warm, seasonally dry regions. The species name 'exserta' (prominent) refers to the distinctly protruding inflorescence, which makes this species particularly characteristic.
Characteristics:
Tillandsia exserta forms a compact to medium-sized rosette of firm, gray-green to silvery leaves densely covered with trichomes. The leaves are narrow, slightly curved, and appear more robust than soft overall. The inflorescence is upright, clearly extending above the rosette, and bears colored bracts from which violet to blue flowers emerge. After flowering, the plant usually produces several offsets.
Care Instructions:
Light: bright to very bright; some direct morning or evening sun is well tolerated
Water: regularly mist or briefly soak; in summer 2–4 times per week, in winter much less often; always allow to dry well
Humidity: prefers medium to higher humidity with good air circulation
Fertilizer: in spring and summer 1–2 times per month with our special Tillandsia or orchid fertilizer in diluted form
Temperature: ideally 18–30 °C, temporarily warmer; in winter not below 12–14 °C
Note: Tillandsia exserta is particularly well-suited for mounting on wood or cork. It is important to ensure very good ventilation, as the species is sensitive to permanently moist conditions.
Our greenhouses are equipped with modern energy screens and double glazing to efficiently save on heating costs. Additionally, we collect rainwater over the entire roof area of 9,000 square meters and use only this water to irrigate all our crops. We collect the rainwater in underground tanks with a total volume of 600,000 liters.
Since 2007, we have been heating our entire operation with a fully automated 850 kW wood chip heating system and a 100,000-liter buffer storage tank. Environmentally friendly and CO2-neutral. Only to support during very cold winter days and nights is a conventional oil heating system available.
Since 2014, the heating has been supported by a solar thermal system with an annual yield of about 20 megawatt-hours.
In 2020, we installed a photovoltaic system with 30 kW peak and have been producing more green electricity per year than our entire operation requires.
Since 2021, we use exclusively pots for our self-produced plants that are not only 100% recyclable but are also entirely made from recycled pots. To this end, we collect all used pots that arise in our operation and have them picked up in big bags by our pot supplier Göttinger. There, the pots are cleaned and processed in a water-free recycling facility into new pots that come back to us.
