Petunias vs. Surfinias: Trailing vs. Upright Types

'Surfinia' (Suntory, Japan) and 'Wave' (Kirin, Japan) are vegetatively propagated trailing petunias for baskets and groundcover. 'Supertunia' (Proven Winners) is similar. Upright petunias are different hybrids — they grow 18-21" tall, ideal for pots, not hanging.

For trailing types: seek Wave, Supertunia, or Surfinia. For upright: avoid those three. All petunias need low-phosphorus fertilizer (phosphorus blocks iron, calcium, magnesium). Don't overwater or overfertilize. Modern trailing types self-clean — no pinching needed.
