Surdiva flowers from May and continues until the first frost around November. They can withstand rain and heat well. So an ideal plant.
It is an easy garden plant. Water them normally, not too much. And don’t let the plant dry out either. A little plant food now and then and your plant will bloom all summer long.
For all plants in containers and pots, it is best to plant them in good quality potting soil. Not in garden soil or soil from your garden. This dries out too quickly in pots. A good potting soil has such a structure that moisture is retained well, plant food can be absorbed and air can reach the roots. A good start is the best you can give this beautiful plant. She will reward you with a multitude of flowers.
