Telekia speciosa (Schreb.) Baumg. is a max. 150 cm high perennial, t he plant has yellow flowers with 5-8 cm. During the experiment, Telekia speciosa (Schreb.) Baumg was planted in the Buda Arboretum to places of different light int ensity (sunny, semi shade, shade). We planted 10-10 plants in the beds. The parameters investigated are as follows: phenological periods of Telekia speciosa , the height of plants, the length of leaf blade, t he number of leaves per plant, the beginning of flowering, the number of flowers per plant, the dia meter of flowers. We can state that semi shadow is the optimal circumstances in Buda Arboretum for the plant. Under such ecological conditions robust growth of plants was observed, the leaves were big and healthy. The average number of leaves per plant was 15,9, the average length of blade was 23, 8 cm. In the sunny bed the leaves grew bigger, but gnawed snails and the leaves had brownish spots. In the shadow bed the plants grew poorly. The mean number of leaves per plant was 7.6; the mean length of blade was 23,3 cm. The highest flower was observed in the sunny place (8.19 cm), but in the s emi shadow circumstances the flowers were decorative too.
