How Many Wave Petunia Plugs Per Basket Size?
Getting the plug count right is the foundation of a full, lush basket. Too few plants and you'll have gaps; too many and the roots compete and the basket dries out too fast. Here's the sweet spot for wave petunias:
- 12-inch hanging basket: 4 wave petunia plugs — the perfect starter basket with great coverage and easy care
- 14-inch hanging basket: 5 wave petunia plugs — a fuller display with room for one or two filler plants
- 16-inch hanging basket: 6 wave petunia plugs — the showstopper size, cascading color on every side
These counts work whether you're planting a single-color basket or a mixed combination. When adding filler plants like lobelia or bacopa, you can reduce the petunia count by one to give everyone enough root space.
Easy Wave vs. Shock Wave vs. Tidal Wave: Which Should You Choose?
Not all wave petunias behave the same way in a basket, and knowing the differences helps you design combinations that actually work together.
Easy Wave Petunias are the most popular choice for hanging baskets. They produce large, 2–3 inch blooms on vigorous trailing stems that cascade beautifully over basket edges. Easy Wave is forgiving, heat-tolerant, and available in the widest color range — from soft pastels to deep velvets. See our full guide to Wave, Easy Wave, Shock Wave & More for a complete variety breakdown.
Shock Wave Petunias are more compact with smaller, denser flowers and a slightly mounding habit. They're excellent in mixed baskets where you want a fuller, more textured look without the aggressive spread of Easy Wave. Shock Wave varieties hold their shape beautifully even in heat and wind.
Tidal Wave Petunias are the powerhouses of the group — the most vigorous, tallest-growing, and widest-spreading of the three. In a large 12-inch basket, a single Tidal Wave plant can fill an entire side. Use them as the dramatic anchor in a mixed basket or plant them solo for a jaw-dropping single-variety display.
The Best Color Combinations for Hanging Baskets
This is where the real fun begins. Wave petunias come in such a rich palette that the combination possibilities are nearly endless. Here are some of our favorite proven pairings:
🌊 Coastal Breeze Basket
Easy Wave Blue + Easy Wave Coral Reef + white bacopa
This combination captures the colors of a summer shoreline — cool blue waves, warm coral, and crisp white foam. Plant 2 Blue, 2 Coral Reef, and tuck bacopa around the edges for a soft, cascading finish. Stunning in a 14-inch basket.
💜 Jewel Tone Royale
Easy Wave Berry Velour + Tidal Wave Hot Pink + Shock Wave Deep Purple
Rich, saturated, and absolutely dramatic. The deep berry and purple anchor the basket while hot pink adds electric energy. This is a 16-inch basket combination — give it room to shine.
🌸 Romantic Garden
Easy Wave Beach Comber Mix + white lobelia + pink verbena
Soft, romantic, and cottage-garden perfect. The Beach Comber Mix brings warm peachy-pink tones that pair beautifully with the delicate white of lobelia and the rosy warmth of verbena. Perfect for a 14-inch basket on a shaded porch.
🔥 Sunset Fire
Easy Wave Coral Reef + Tidal Wave Hot Pink + orange verbena
Warm, fiery, and impossible to ignore. This combination glows in the afternoon sun and looks spectacular hanging against a white fence or dark siding. Best in a 16-inch basket where the Tidal Wave has room to spread.
🌑 Midnight Drama
Shock Wave Deep Purple + Tidal Wave Purple + silver dusty miller
For gardeners who love a moody, sophisticated look. Deep purple tones layered together with the silvery foliage of dusty miller create a basket that looks almost architectural. Pair with a dark iron hook for maximum impact.
🌿 Soft & Natural
Easy Wave Mix + blue lobelia + white bacopa
Let the mix do the work. The Easy Wave Mix brings a natural, meadow-like blend of colors that pairs effortlessly with the soft blue of lobelia and the delicate white of bacopa. This is the easiest combination to plant and one of the most beautiful.
The Best Filler Plants for Wave Petunia Baskets
Fillers add texture, contrast, and depth to your wave petunia baskets. Here are the top performers:
- Lobelia: Delicate, fine-textured flowers in blue, white, or purple. Trails beautifully and loves the same conditions as wave petunias. Perfect for softening the edges of a basket.
- Verbena: Bold, heat-tolerant, and available in a wide color range. Verbena adds a different flower shape and texture that contrasts beautifully with petunia blooms.
- Bacopa: Tiny white or pink flowers on trailing stems. Bacopa is the ultimate soft filler — it weaves between petunia stems and creates a lacy, romantic effect.
- Sweet Alyssum: Fragrant, honey-scented clusters of tiny white or purple flowers. Alyssum attracts pollinators and adds a beautiful fragrance to your porch or patio.
- Calibrachoa (Million Bells): Small petunia-like flowers in an enormous color range. Calibrachoa is a natural companion to wave petunias and creates a seamless, layered look.
- Dichondra Silver Falls: Silvery trailing foliage that cascades dramatically. Use it as a foliage accent to make your petunia colors pop even more.

Tips for Growing Wave Petunias from Seed for Baskets
Growing your own plugs from seed is incredibly rewarding and saves a lot of money compared to buying transplants. Here's what you need to know:
- Start 10–12 weeks before your last frost date. Wave petunias need a long head start to be basket-ready by planting time.
- Use pelleted seeds. Pelleted wave petunia seeds are much easier to handle and space correctly than raw seeds. All of our seeds are pelleted for this reason.
- Don't cover the seeds. Petunia seeds need light to germinate. Press them gently onto the surface of moist seed-starting mix and do not cover.
- Keep temperatures at 70–75°F. Consistent warmth is key for fast, even germination — usually 7–10 days.
- Provide bright light immediately after germination. Seedlings that don't get enough light become leggy and weak. Use grow lights or a very bright south-facing window.
- Fertilize regularly once true leaves appear. Wave petunias are heavy feeders. Use a balanced liquid fertilizer weekly once seedlings are established.
- Harden off before planting outdoors. Gradually introduce your plugs to outdoor conditions over 7–10 days before planting in baskets.

Caring for Your Wave Petunia Hanging Baskets
Wave petunias in hanging baskets need a little more attention than in-ground plants, but the payoff is spectacular. Here are the key care tips:
- Water daily in hot weather. Hanging baskets dry out fast, especially in summer heat. Check the basket every morning and water thoroughly until it drains from the bottom.
- Fertilize every 7–10 days. Use a high-phosphorus liquid fertilizer to encourage continuous blooming. Wave petunias are heavy feeders and will stop blooming without regular feeding.
- Deadhead or shear back mid-season. If your basket starts to look leggy or bloom production slows, cut the plants back by one-third. They'll rebound with a fresh flush of blooms within 2–3 weeks.
- Hang in full sun. Wave petunias perform best with at least 6 hours of direct sun per day. More sun = more blooms.
- Protect from heavy rain. Large petunia blooms can be damaged by heavy downpours. Move baskets to a covered area during storms if possible.
Frequently Asked Questions
How many wave petunia plugs go in a 12-inch hanging basket?
For a 12-inch hanging basket, plant 4 wave petunia plugs. This gives each plant enough room to spread and cascade beautifully over the sides without overcrowding.
How many plugs do I need for a 14-inch hanging basket?
A 14-inch hanging basket works best with 5 wave petunia plugs. The extra space allows for a fuller, more dramatic cascade of blooms.
How many wave petunias should I plant in a 16-inch basket?

What is the difference between Easy Wave, Shock Wave, and Tidal Wave petunias?
Easy Wave produces large blooms with vigorous trailing growth — the most popular basket variety. Shock Wave is more compact with smaller, denser flowers and a mounding habit. Tidal Wave is the most vigorous of the three, growing taller and spreading wider — perfect as a dramatic anchor in large baskets.
What are the best filler plants to combine with wave petunias?
The best fillers include lobelia (delicate blue or white contrast), verbena (bold color and heat tolerance), bacopa (soft trailing accent), sweet alyssum, and calibrachoa. These complement wave petunias beautifully and add texture and depth.
Can I grow wave petunias from seed for hanging baskets?
