Know before you buy
Yes, the Mighty Mosaic variety is specifically bred to tolerate full sun, provided the environment has high humidity. If you live in a drier climate, you may want to provide some afternoon shade to prevent leaf scorch.
Pelleted seeds are coated in a clay-like material to make them larger and more uniform, which makes them much easier to handle and space out during planting. Being untreated means they have not been coated with fungicides or pesticides, making them a preferred choice for organic gardeners.
No, this variety is known for its late-flowering habit, which keeps the plant's energy focused on producing its vibrant, multi-hued foliage. You won't need to worry about constant deadheading to maintain the plant's appearance.
For successful germination, you should maintain a soil temperature between 70-75°F. Once the seedlings are established, they prefer a grow-on temperature of 70-75°F during the day and a slightly cooler 60-65°F at night.
Since these plants reach a mature spread of 18-22 inches, you should space them at least 18 to 24 inches apart. This ensures adequate airflow and gives them enough room to reach their full height of 18-26 inches.
Absolutely. Their compact, upright growth habit makes them an excellent choice for containers and hanging baskets, as well as for filling in gaps in landscape borders.
