Introduction
• The economic importance of the ornamental plant production has shown remarkable growth.
• The goal of our work was to make a virological survey of herbaceous ornamental plants in Hungary.

Materials
• 54 samples (Echinacea purpurea, Heuchera sanguinea, Hosta sp., Paeonia lactiflora, Petunia sp., Pulmonaria sp. and Zanthedeschia aetiopica).
• Samples were collected from companies, public areas and private gardens, from different regions (Felsőpáhok, Gyenesdiás, Helvécia, Hódmezővásárhely, Keszthely, Nyírbátor, Tata) of Hungary.

Methods
• DAS ELISA test
• CMV, PVX, PVY, TMV, ToMV and TSWV

Results• Mosaic, chlorosis, leaf deformation, and necrotic
lesions have been observed on the collected plants.
• 11 samples were infected with the examined viruses.
• PVY in the Pulmonaria sp.• TSWV in the Heuchera sanguinea.• CMV, PVY, TMV and TSWV complex infection in
one Echinacea purpurea.• CMV (5), PVY (4), TMV (2) in the Petunia
samples [P. Surfinia Blue ’Sunblu’ (PVY, TMV and CMV) and P. Surfinia Purple ’Shili Brillar’ (PVY and TMV) ].

Discussion
• The identified viruses play an important role not only in the horticultural, but also in the other crop production.
• The identification of viruses in an ornamental crop is the first step to the control of diseases.
• The intensification of ornamental plant production, the introduction of contaminated propagation plant material, and the outbreaks of virus vectors may play role in the establishment and distribution of viral diseases.
• All of the investigated plants are perennial, except petunia ones. Perennials as virus reservoirs have a special great importance in the epidemiology of viruses.
