When it comes to versatility, color range, and sheer design flexibility, the Lobelia Riviera series stands in a class of its own. Bred for compact trailing habit, exceptional branching, and a color palette that spans deep marine blues to soft rose and crisp white, Riviera lobelia is the workhorse of professional container programs, landscape edging, and mixed hanging baskets.
Whether you're a commercial grower building a high-volume spring program, a landscaper designing color-coordinated beds, or a farmers market vendor looking for a reliable top-seller, this guide covers everything you need to know about growing and selling Lobelia Riviera seeds at scale.
What Makes the Riviera Series Different?
The Riviera series was developed specifically for the professional grower market. Key characteristics that set it apart from other lobelia series:
- Compact trailing habit — Riviera plants trail and mound simultaneously, making them equally effective in hanging baskets, window boxes, and landscape edging without the aggressive cascade of the Regatta series.
- Exceptional branching — naturally well-branched plants mean fuller, more floriferous containers with less pinching required.
- Broad color range — from deep midnight blue to marine, sky blue, lilac, rose, blue splash, and white, Riviera offers the widest color selection of any lobelia series.
- Pelleted seed precision — all Riviera varieties are available as multi-pelleted seed, making commercial seeding accurate and efficient even at high volumes.
- Consistent uniformity — Riviera is bred for tight crop timing, meaning your trays finish together and your production schedule stays on track.
Lobelia Riviera Varieties: Full Color Guide
Here is a complete breakdown of every Riviera color available in bulk, with design notes and best-use recommendations for each.
Lobelia Riviera Marine Blue
The deepest, most saturated blue in the Riviera lineup. Marine Blue produces rich, jewel-toned flowers that photograph beautifully and command attention in retail displays. It is the top-selling individual Riviera color for most commercial growers and the anchor of any blue-themed container program. Pairs exceptionally well with white bacopa, silver dusty miller, and yellow calibrachoa.
Lobelia Riviera Midnight Blue
Slightly deeper and more violet-toned than Marine Blue, Midnight Blue is the choice for sophisticated, moody container designs. It works beautifully in dark-themed mixed planters alongside deep purple petunias, black sweet potato vine, and burgundy coleus. A strong seller for upscale garden centers and landscape designers.
Lobelia Riviera Sky Blue
Bright, clear sky blue — lighter and more cheerful than Marine or Midnight. Sky Blue is the go-to for cottage garden aesthetics, pastel mixed baskets, and spring programs targeting home gardeners. It pairs naturally with pink and white impatiens, soft yellow marigolds, and white alyssum.
Lobelia Riviera Blue Splash
A unique bicolor variety featuring blue flowers with a distinctive white splash or eye. Blue Splash adds visual texture and interest to mixed containers that solid colors cannot achieve. It is an excellent choice for growers who want to differentiate their program and offer something customers won't find at big-box retailers.
Lobelia Riviera Lilac
Soft lavender-lilac flowers that bridge the gap between blue and pink in mixed container designs. Riviera Lilac is essential for pastel programs, Mother's Day baskets, and any design calling for a gentle, romantic color palette. It pairs beautifully with soft pink petunias, white verbena, and pale yellow calibrachoa.
Lobelia Riviera Rose
Warm rose-pink flowers that add warmth and femininity to mixed plantings. Riviera Rose is a strong performer in spring gift programs, Mother's Day production, and mixed baskets targeting the home gardener market. It complements coral and salmon tones exceptionally well.
Lobelia Riviera White
Clean, pure white flowers that serve as the essential neutral in any mixed container program. Riviera White is indispensable for wedding season production, white-themed landscape installations, and high-contrast mixed baskets. It also functions as a visual rest between bold colors in complex mixed plantings.
Lobelia Riviera Mix
A professionally balanced blend of all Riviera colors in a single pack. The Riviera Mix is the most efficient option for growers who want maximum visual variety without managing multiple individual color SKUs. Ideal for mixed hanging baskets, color bowls, and any program where variety is more important than color control.

Growing Lobelia Riviera from Seed: Production Notes
Germination
- Surface sow only — do not cover pelleted seed. Lobelia requires light to germinate.
- Soil temperature: 70–75°F (21–24°C). Use bottom heat mats for winter sowing.
- Germination time: 10–18 days for pelleted Riviera seed.
- Moisture: Mist gently to keep medium consistently moist without displacing seeds.
- Lighting: 16-hour photoperiod with supplemental lighting strongly recommended for January–March sowing.
Crop Timing for Riviera
- Spring sales (April–May): Sow 12–14 weeks before target sale date.
- Mother's Day peak (May 10–12): Sow in early January.
- Summer basket programs: Sow March–April for June–July sales.
- Riviera finishes slightly faster than upright types — plan accordingly if mixing series in the same production cycle.
Container Recommendations
- 4-inch pots: 1 plant per pot. Riviera's compact habit fills a 4-inch pot beautifully without overcrowding.
- 10-inch hanging baskets: 3–4 Riviera plants per basket, or 2 Riviera + 1–2 complementary annuals for mixed baskets.
- Window boxes: Space plants 6–8 inches apart. Riviera's trailing habit fills window boxes quickly and evenly.
- Landscape edging: Plant 6 inches apart for a continuous ribbon of color. Riviera's compact habit requires less maintenance than trailing types in landscape settings.
Riviera vs. Regatta vs. Palace: Which Series for Which Program?
All three are compact-to-trailing lobelia series, but they serve different production needs:
- Riviera — Best all-around series for mixed programs. Compact trailing habit works in baskets, window boxes, edging, and 4-inch pots. Widest color range. The most versatile choice for growers who want one series to cover multiple uses.
- Regatta — Purpose-built for hanging baskets. More aggressive trailing habit than Riviera. Fewer colors but excellent heat tolerance for a trailing type. Choose Regatta when hanging baskets are your primary product.
- Palace — Compact mounding habit for bedding flats and 4-inch pots. Less trailing than Riviera. Best for landscape edging and flat programs where a tidy, upright mound is preferred over a trailing habit.

Frequently Asked Questions: Lobelia Riviera Seeds
What is the Lobelia Riviera series best known for?
The Riviera series is best known for its exceptional color range, compact trailing habit, and versatility across multiple container formats. It is one of the most widely grown lobelia series in professional greenhouse production because it performs reliably in hanging baskets, window boxes, 4-inch pots, and landscape edging — all from the same seed program.
How does Riviera lobelia differ from Regatta lobelia?
Riviera has a more compact trailing habit than Regatta, making it more versatile across container sizes. Regatta trails more aggressively and is purpose-built for hanging baskets. Riviera also offers a wider color range, including the unique Blue Splash bicolor. For growers who need one trailing series to cover multiple uses, Riviera is the more flexible choice. For dedicated hanging basket programs, Regatta's stronger cascade habit may be preferred.
Is Lobelia Riviera heat tolerant?
Riviera is a cool-season annual that performs best between 55–75°F. Like all lobelia, it will slow or pause blooming in peak summer heat above 85°F. Shearing plants back by one-third during heat stress encourages a strong rebloom when temperatures cool. For summer programs in hot climates, position plants in partial afternoon shade to extend the bloom period.
How many Riviera plants do I need per hanging basket?
For a 10-inch hanging basket planted with Riviera lobelia only, use 3–4 plants. For mixed baskets combining Riviera with other annuals, 2 Riviera plants per basket is typically sufficient. Riviera's natural branching habit fills containers quickly, so avoid overcrowding — it leads to poor air circulation and increased disease pressure.
What is the Riviera Mix, and is it worth buying over individual colors?
The Riviera Mix is a professionally balanced blend of all Riviera colors in a single pack. It is the most efficient option for growers who want color variety without managing multiple SKUs. The tradeoff is that you cannot control the ratio of individual colors. For programs where color control matters — such as themed landscape installations or color-coordinated retail displays — buying individual colors gives you more precision. For general mixed basket programs and farmers market displays, the Mix is the better value.
Can I use Riviera lobelia for landscape edging?
Yes — Riviera's compact trailing habit makes it an excellent landscape edging plant. Space plants 6 inches apart for a continuous ribbon of color along bed edges, pathways, and borders. Riviera requires less maintenance than more aggressive trailing types in landscape settings and holds its shape well through the season. Marine Blue and Midnight Blue are the most popular colors for landscape edging programs.
How do I get the best germination from pelleted Riviera seed?
Surface-sow pelleted Riviera seed on a fine, well-draining germination medium — do not cover. Maintain soil temperature at 70–75°F using bottom heat mats. Mist gently to keep the medium consistently moist as the pellet coating dissolves. Provide supplemental lighting on a 16-hour photoperiod. Expect germination in 10–18 days. Avoid overwatering at the seedling stage, as lobelia is susceptible to damping off.
What is the minimum order quantity for bulk Riviera lobelia seeds?
Our bulk Riviera lobelia seeds are sold in packs of 1,000 multi-pelleted seeds per variety. This pack size is designed for commercial growers, landscapers, and high-volume producers. For smaller quantities suitable for home gardeners and small-scale growers, visit www.trailingpetunia.com.
Which Riviera color sells best at farmers markets?
Marine Blue consistently outsells other Riviera colors at farmers markets and garden centers. Deep, saturated blue is the most sought-after color in the lobelia category — customers recognize it immediately and it photographs well for social media. Stock 40–50% Marine Blue or Midnight Blue in your Riviera program, with Sky Blue, Lilac, and the Mix rounding out the balance. White is essential as a neutral but rarely the top individual seller.
How long does Riviera lobelia bloom?
Under ideal cool-season conditions (55–75°F), Riviera lobelia blooms continuously from first flower through the season. In climates with hot summers, expect a natural pause in blooming during peak heat. Shear plants back by one-third in midsummer and they will rebloom strongly in late summer and fall. In USDA zones 8–10, Riviera can be grown as a fall and winter annual for nearly year-round color.
