Surfinia White

Petunia

70d to harvest

Surfinia White pours out a cloud of pure, luminous white blossoms that glow softly against the trailing foliage—each flower a delicate, velvety funnel with a crisp, clean presence. The plants spread with a tidy, cascading habit, forming a dense, cushiony drape that stays floriferous through the season. Ideal for hanging baskets, window boxes, and garden edges where its trailing cascade can be admired in full bloom.

Frequently Asked Questions

Why are my Petunia × atkinsiana (Surfinia White) plants getting gray patches or wilting, and what should I do?

Gray mold (Botrytis) often shows up as gray, fuzzy growth or spreading blotches when foliage stays wet and airflow is poor. Remove affected leaves, water at the soil line (not the petals), and space plants so leaves don’t touch. If it’s spreading quickly, apply a labeled fungicide for Botrytis on ornamentals and keep night foliage as dry as possible.

How often should I water Petunia × atkinsiana during the main growing season?

During active growth in full sun, water deeply when the top 1 inch of potting mix or soil feels dry—typically about 1–2 times per week, but hot weather containers may need more frequent watering. Water until excess drains from the bottom, then let the surface dry slightly before watering again to prevent root stress and disease. Consistently soggy mix can trigger fungal problems, while letting it fully dry repeatedly can cause flower drop and slowed growth.
