There isn't a better annual for pots in the garden and on the patio. They come in so many colors you can find which ever one that you need to go with other plants, very easily.

Petunias do WONDERFULLY in zone 9a. They love sunshine and absolutely flourish in hanging baskets or tall urns, from which they are even prettier when they become leggy. I water mine (with a fertilizer mixed into the water) every other day and pretty much leave them alone the rest of the time, and they have absolutely burst with blooms all over them and trailing around them. They have NEVER given me any problems.

Sow petunia seeds 8-10 weeks before planting out. Seeds are extremely tiny. Just sow on the surface or the soil without covering. Keep moist and tiny the little green sprouts will appear within 2 weeks. You’ll need to transplant them into larger containers as they grow. Plant seedlings outdoors after your last frost date in full sun and well-drained soil. Pinch the young seedlings back to encourage branching, After they’ve become established give them an occasional feeding. Dead head often and water regularly

Grandiflora Petunia 'Daddy' series have large and darkly veined flowers. The foliage is very sticky and trails well in baskets and other containers. These are perennials which are treated as annuals.
