Abstract
The purpose of this study is acclimization evaluate of five wild Achillea in cultivation condition and ornamental potential. The seeds of wild species (From Khorasan Razavi, Shiraz and Karaj area, Iran) were sownt in pots in September 2006. After initial growth, the seedlings were transplanted in main plots (30×40 cm interval) in November 2006. Phonological and morphological characteristic at different growth stage were recorded. An experiment conducted in factorial randomized based on complete block design (RCBD) with 5 treatments and 3 replications that Achillea species were treatments. The results showed that different species have special traits that could be used depend on our goal. A. millefolium has the highest flowering period (100 day) and plant height (nearly 1 meter). A. biebersteinii was better than other species in respect of inflorescence number, flower diameter and flower height. A .wilhelmsii and A. eriophora had the highest lateral inflorescence number and early flowering. This species because of good acclimization, tolerant to unfavorable conditions, long flowering period, perennial habit and bearing beautiful and big flowers, seems to be suitable plants for use in green space.
