Manganese toxicity is very well documented. Some of plant is so tolerant to Mn toxicity to high level of available Mn in the root zone. The reason is caused by low rate of Mn up-take by roots, retention of Mn in the roots and ability of the top to tolerate high level of Mn concentration in the tissue. The symptoms such necrosis. crinkled and reduced in leaf size. In Banda Aceh Rose flower is planted around the houses verandah, office and garden. The beautifulness and colorful of the flower is
so expressive for the people here after disaster tsunami. Compare in Brazil the flower is more a high value in world trade in between the country, and the production use the green house as ornamental plant. Improving of soil physic by Organic Matter (0M) and plant growth defected by heavy metal (Mn) is emphasized in this study. The experiment had been conducted during this year; 2010 -- 2011, in the second was the
field experiment in the garden of faculty Agriculture Univ. Syiah Kuala, Banda Aceh. At the early of plant growth, application OM by ratio (I: I) in between TS and OM was so affected to the Rose plant. Beside, the soil could reveal more water (50 %) and lead the expansion of root plant. Rose plant in the field resulted in sophisticated environment. 25 flowers were found for each plant under the treatment I0 cm on top soil. While, application high level Mn (250 uM) destroy the canopy of the flowers by the senescent processes then the petals of flower fallen down to the grown.

Key words : Mn toxicity, organic matter, Rose flowers and sophisticated environment.
