Visitors walk in the main greenhouse of the Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine in Kyiv on February 11, 2026, amid the Russian invasion of Ukraine. Roman Ivannikov has spent around 30 years pampering orchids, azaleas and figs at Ukraine's National Botanical Garden but power cuts triggered by Russian strikes have put his cherished plants in mortal danger. The almost-daily barrages paired with the cold snap have put lives at risk and created an unprecedented threat for Ivannikov's pride and joy: a collection of almost 4,000 tropical species.
