My Asian sister-in-law was given turmeric bulbs by her mother. She is flying to the Schengen space via Taipei and then Amsterdam.
Will those products be allowed in by EC laws?
That's unlikely - not without some effort for extra documentation. Any plants being brought in have to be declared, and you need certifications with them: https://ec.europa.eu/food/plant/plant_health_biosecurity/non_eu_trade_en
certain plants, plant products and other objects (listed in Part B, Annex V - Directive 2000/29/EC) entering the EU must have a phytosanitary certificate guaranteeing that they are:
free from quarantine harmful organisms and practically free from other harmful organisms;
in line with the plant health regulations of the importing country.
The exporting country's national plant protection authorities issue the certificates. Once in the EU, a plant passport may replace the phytosanitary certificate for imported plants, plant products and other objects which are also listed in Part A of Annex V.
There are some exceptions, but it's a LOT of legalese to wade through. Point is, you will be asked about it and the onus will be on you to provide evidence that it's "safe" to be allowed in to the country.
