 Description 
Paracress is an ancient perennial spice and medicinal plant with origins in Brazil and Peru. The versatile herb has numerous medicinal properties that are antibacterial, antiviral, immune-boosting, salivation-inducing and anesthetic, which is why it is used as a local anesthetic in dental treatments. It is used as a poultice for fungal infections and also for pain relief from rheumatism or gout. The plants grow in compact clumps and, if there is enough light, form new flowers all year round. The leaves have a tingling effect and taste fresh, a mixture of sweet, sour and salty, which makes them ideal for salads. The dried leaves have a spicy and piquant taste. It has been cultivated on a large scale in South America since ancient times, in some regions of northern Brazil it is used as a spice, in the USA mainly as a salad and in India as a steamed vegetable. The flowers and leaves are edible and are a bee food plant.

 Sowing by climate zone 
Subtropic climate (Mediterranean) (e. g. B. Portugal, Spain, Italy)
Pre-cultivation from February to August is recommended. The plants should ideally be planted in a sunny location.
Moderate climate (e. g. B. Germany, Switzerland, Poland)
Pre-cultivation from March to June is recommended. The plants should ideally be planted in a sunny location.

 General recommendations 
Pre-cultivation is recommended. For pre-cultivation, sow the seeds in a small bowl and let the seedlings grow until the first visible paracress leaves appear, then transplant them into the desired containers. After transplanting, let the seedlings grow at moderate temperatures until they are ready to be planted out as seedlings. Plant the seedlings in the bed from the second pair of leaves after the cotyledons.
Paracress - Jambú does not tolerate waterlogging.

 Additional tips 
Because paracress is only partially frost-hardy, a sheltered location with winter protection is recommended for outdoor cultivation in temperate climates. When grown in pots, the plant is overwintered at temperatures between 5 and 15°C, ideally in a winter garden. In order to quickly obtain a fine, crumbly and permeable soil with good nutrient and water storage capacity, additional incorporation of biochar and primary rock flour is recommended.

 Type of propagation 
Propagation occurs via seeds or cuttings.

 Plant care 
Regular watering results in faster growth. No fertilization necessary.
