Varieties

The range of species and varieties of basil is currently very diverse, and for the sake of clarity, we can divide the species Ocimum basilicum (true basil) into the following groups based on the differences in appearance and taste, which are important for the market and culinary use: 

  • - Mediterranean and European basils are referred to as sweet basils with anise aroma 
  • - Robust species with large leaves, which are usually stronger and sharper in taste than other types of basil 
  • - Compact basils (the so-called dwarf type) – they have short and small leaves, short internodes, compact species suitable for growing in containers 
  • - Thai basils with red veining of leaves and stems, and a sweet anise scent 
  • - Opal (purple) basils are characterized by a dark purple color and the traditional taste of sweet basil, they have red to purple leaves and flowers -
  • Lemon basil with a strong citrus aroma
  • - Cinnamon basils have a distinct cinnamon smell and taste


Agricultural cultivation techniques 

Basil is sensitive to frost, which is why it is grown as an annual plant in our conditions. It is usually pre-grown in the form of transplants, which are planted after May 15, when there is no longer a threat of frost.
