Catharanthus belongs to perennial evergreens. Originally from distant Madagascar, he has long managed to find his fans in the vastness of our homeland. Compact dense bushes with neat dark green leaves bloom very beautifully. From the end of spring to the very middle of autumn, large multi-colored flowers flaunt on them. Pink or white, blue or purple, they bloom in “bunches” at the tops of the shoots. This is why gardeners love the catharanthus. Although he is a perennial, due to the thermophilic nature of our winters, the plant cannot survive. Therefore, in the open field it is grown as an annual crop, by annual planting. How to grow a catharanthus? The easiest way to do this is with seeds. Planting material is always available, you can buy it in the store. The seeds themselves sprout quite well, in addition, this method allows you to immediately get a whole flower bed of colorful bushes.
