Pretty Grand petunias make tidier baskets than traditional petunias and make growing a little bit easier. This controlled growth collection needs fewer to no PGRs and is suitable for cold growing. Better branching with improved airflow assures less chance of disease, especially Botrytis, for better shelf life at retail and less waste. The tight bloom window across each series lets you ship and display all colours at the same time. With enhanced, longer performance in beds and landscapes, the plants hold together and don’t lodge later in the season like traditional petunias can.
