Know before you buy
Pelleted seeds are coated in a clay-based material to make them larger and more uniform in shape. This makes them much easier to handle and sow accurately, especially since petunia seeds are naturally tiny and difficult to space.
No, these seeds are untreated. They do not have any chemical fungicides or pesticides applied to the coating.
Since these petunias have a spread of 14 to 16 inches, you should space them about 14 to 15 inches apart in your garden beds or containers to allow for proper airflow and growth.
You can expect germination to occur within 7 to 12 days, provided the soil temperature is maintained between 70 and 75°F.
No, these are annual flowers. They are bred to complete their entire life cycle—germinating, blooming, and setting seed—within a single growing season.
The Tritunia series is a high-performance blend that combines the best traits of the Ultra, Storm, and Bravo grandiflora series. It is specifically engineered for exceptional uniformity in both growth habit and flower timing, ensuring a consistent look across your planting.
