Hyssopus officinalis L has recently attracted particular attention as a valuable raw material for pharmaceuticals. To identify the biomorphological features of Hyssopus officinalis L., a field experiment was initiated in 2020 in the Kherson region, Ukraine. Samples of Hyssopus officinalis L of the local ecotype No. 108 were selected for the research. It was noted that seedlings in the flowering phase differ in terms of the timing of the beginning of flowering and flower colour. Plants of Sample 1-20 (pink-flowered) bloom first. After 3-4 days, the beginning of flowering is noted in sample 3-20 (blue-flowered), and after another 2 days, Sample 2-20 (white-flowered) begins to bloom. The height of first year plants ranged from 50 to 60 cm. The diameter of the bushes varied from 20 to 35 cm. The central shoot consisted of 17 to 38 first-order shoots. The largest size of the inflorescence of the first and second order shoots is in sample 3-20. Sample 2-20 has slightly higher average values of the length of the inflorescence of the first order shoots than in Sample 1-20.
