A directive issued by Greece’s National Public Health Organization has sparked widespread debate after recommending the removal of oleander plants from schools and public spaces due to concerns over toxicity.
The guidance, which targets one of the most common ornamental plants in the country, has instructed school administrators to remove oleander from educational environments as a precautionary safety measure for children.
Concerns Over Environmental Impact
The recommendation has drawn strong criticism from environmental and horticultural professionals, who argue that the measure is disproportionate and could have significant ecological consequences.
The Panhellenic Association of Professional Agronomists has opposed the blanket removal approach, calling instead for education and targeted awareness. Its president has warned that mass uprooting of plants would be economically, socially, and environmentally damaging.
Experts cited by the association note that poisoning cases linked to plants are extremely rare, with oleander accounting for only a very small fraction of incidents recorded by Greece’s Poison Control Centre.
Toxicity Risks Highlighted in Directive
The guidance references the plant’s toxic compounds, including oleandrin, which can cause serious heart rhythm disturbances and, in rare cases, be fatal if ingested.
According to the directive, children are primarily at risk through accidental ingestion of leaves or flowers, while adults may be exposed through skin contact or inhalation of smoke from burning plant material.
To reduce risk, the health authority recommends removing oleander from schools, playgrounds, parks, and other public areas, replacing it with non-toxic vegetation where possible. In locations where removal is not immediately feasible, fencing and warning signs are advised, along with public education campaigns.
Debate Over Risk and Proportionality
Environmental organizations and professional bodies have challenged the scientific basis of the directive, arguing that it lacks a full risk assessment and overstates the actual danger.
They cite data suggesting that plant-related poisoning cases represent a very small percentage of total incidents, with oleander accounting for only a minor share of those.
Supporters of the directive, however, emphasize the importance of precaution in spaces frequented by children, pointing to documented cases of accidental ingestion, even if rare.
