The research was carried out in the agricultural season 2016-2017 the village of DweirRaslan Tartous governorate with three planting dates (20 November - 10 December - 1 January) and three densities (12 - 14 - 16 plants / m2) Where the planting time was the main pieces and the plant density occupied the dissecting pieces once to study the effect of planting date and plant density on some morphological characteristics of white thermos plant. The results showed that dates of the early dates (November 20) were higher in plant height, with an average of 64 cm and surface area of the paper surface at an average of 24.367 thousand. M 2 / ha and in shape of the length of the century with an average of 7.50 cm. As for the plant density, the plants of density12 plants / m 2 in the height of plant exceeded an average of 65.6 cm and length of the century with an average of 8.13 cm, while the plants of density 16 plants / m 2 in the area of paper area average 24.213 thousand.
