Petunia Multiflora Rose of Heaven. This petunia has a beautiful pink colour, is easy to cultivate and generally problem-free. The seeds are very fine, therefore sow thinly. Sow in a greenhouse in a seed tray at room temperature. After the seedlings emerge, prick out in pots and harden off. When plants are large enough, transplant them to their final spot. Be aware of night frost. Suitable for borders, flower beds, small containers and flower boxes. Sluis Garden, quality seeds from Holland.
