Verbena is one of the most versatile flowering annuals a grower can add to their program. Whether you are filling hanging baskets, designing pollinator gardens, producing cut flowers, or supplying landscape contractors with reliable color, verbena delivers season-long performance with relatively low input costs. This complete grower's guide covers everything you need to know about growing verbena from bulk seed — from variety selection and germination through spacing, zone-by-zone planting schedules, succession planting, and harvest timing for cut flower production.
Why Grow Verbena from Bulk Seed?
Buying verbena in bulk seed quantities gives commercial growers and serious home gardeners a significant cost advantage over purchasing plugs or finished transplants. With 1,000-seed packs available across multiple series, you can scale production to match demand, run succession plantings throughout the season, and maintain consistent variety selection year over year. Verbena germinates reliably when given the right conditions, and modern series like Tuscany, Quartz, and Buenos Aires have been bred specifically for uniformity and performance — making them well-suited to professional production environments.
Top Verbena Series and Varieties for Growers
Not all verbena is created equal. Understanding the growth habit and best use of each series helps you match the right variety to the right application.
Tuscany Series
The Tuscany series is a workhorse for container and basket production. Plants produce dense, mounding habits with excellent heat tolerance and a wide color range. Available varieties include Tuscany Peach, Tuscany Lavender Picotee, Tuscany Rose Eye, and Tuscany Scarlet Eye. The picotee and bicolor types add visual interest that commands premium retail pricing.

Quartz Series
Quartz Blue is a standout in the series — a compact, spreading type with brilliant true-blue flowers that are rare in the verbena category. Excellent for mixed containers, landscape borders, and pollinator plantings. The Quartz series is known for strong disease resistance and consistent performance across a wide range of climates.

Buenos Aires
Buenos Aires is the go-to upright verbena for cut flower production. Plants reach 18–24 inches tall with long, branching stems and clusters of small, richly colored flowers. It is one of the few verbena types that performs well in production rows and holds up in the vase. A must-have for cut flower farmers adding verbena to their mixed bouquet program.
Santos Purple
Santos Purple offers a compact, mounding habit with deep purple blooms that hold color well in heat. It is a reliable performer for landscape contractors and retail growers who need consistent color in 4-inch and quart containers.
Sweetheart Kisses, Vanity Apex, and Polaris ApeX
These newer series bring improved trailing habits, larger floret size, and enhanced heat tolerance to the verbena category. Sweetheart Kisses is particularly popular for hanging basket programs due to its vigorous trailing habit and bicolor flower patterns. Vanity Apex and Polaris ApeX offer strong upright-to-spreading habits suited to mixed containers and landscape mass plantings.
Verbena Germination Guide
Verbena can be a slow and sometimes uneven germinator, but following a few key steps dramatically improves results.
- Pre-chill seeds: Place seeds in a sealed bag in the refrigerator for 5–7 days before sowing. This cold stratification breaks dormancy and improves germination uniformity.
- Sow depth: Cover seeds lightly — about ⅛ inch — as verbena needs darkness to germinate. Do not leave seeds exposed on the surface.
- Soil temperature: Maintain a media temperature of 65–75°F. Use a heat mat if your germination area runs cool.
- Moisture: Keep media consistently moist but not waterlogged. Use a humidity dome for the first 7–10 days.
- Days to germination: Expect germination in 14–21 days. Some seeds may take up to 28 days — do not discard trays prematurely.
- Light after germination: Once seedlings emerge, move to bright light immediately. Verbena seedlings stretch quickly under low light.
Spacing Guide by Application
| Application | Spacing | Notes |
|---|---|---|
| 4-inch containers | 1 plant per pot | Compact types only |
| Quart/gallon containers | 1–2 plants per pot | Trailing types fill faster with 2 |
| 10–12 inch hanging baskets | 3–4 plants per basket | Trailing/spreading types preferred |
| Landscape beds (compact) | 10–12 inches apart | Mounding types |
| Landscape beds (spreading) | 14–18 inches apart | Trailing/spreading types |
| Cut flower production rows | 6–8 inches in-row, 12–18 inches between rows | Buenos Aires; use netting support |
When to Plant Verbena by USDA Zone
| Zone | Indoor Start | Transplant Outdoors | Direct Sow | Grower Notes |
|---|---|---|---|---|
| Zone 3 | Late Feb – Early Mar | Late May – Early Jun | Not recommended | Short season; start early indoors |
| Zone 4 | Late Feb – Early Mar | Mid May – Late May | Not recommended | Protect from late frosts |
| Zone 5 | Early – Mid Mar | Early – Mid May | Not recommended | Harden off 7–10 days before transplant |
| Zone 6 | Mid Mar | Late Apr – Early May | Not recommended | Succession plant every 3–4 weeks |
| Zone 7 | Late Feb – Early Mar | Mid Apr | Apr (after last frost) | Two full production cycles possible |
| Zone 8 | Jan – Feb | Mar – Early Apr | Mar – Apr | Spring and fall crops; avoid peak summer |
| Zone 9 | Dec – Jan | Feb – Mar | Feb – Mar | Treat as cool-season crop; replant in fall |
| Zone 10 | Nov – Dec | Jan – Feb | Jan – Feb | Fall/winter/spring production; summer rest |
| Zone 11 | Oct – Nov | Nov – Dec | Nov – Dec | Year-round possible with heat-tolerant varieties |
Succession Planting for Continuous Production
For growers supplying farmers markets, florists, or landscape contractors, succession planting is the key to maintaining a steady supply of finished verbena throughout the season. Here is a sample succession schedule for Zone 6:
- Sowing 1: Mid-March indoors → Transplant late April → Peak bloom late May through June
- Sowing 2: Early April indoors → Transplant mid-May → Peak bloom mid-June through July
- Sowing 3: Late April indoors → Transplant early June → Peak bloom July through August
- Sowing 4: Mid-May indoors → Transplant late June → Peak bloom August through September
Staggering sowings every 3–4 weeks keeps your production pipeline full and prevents the feast-or-famine cycle common in single-sowing programs.
Verbena as a Cut Flower
While verbena is most commonly grown as a bedding or container plant, upright types — particularly Buenos Aires — have earned a place in the cut flower garden. The small, clustered florets add texture and filler value to mixed bouquets, and the range of colors from deep purple to soft peach complements nearly any palette.
Harvest timing: Cut stems when approximately one-third of the florets on the cluster are open. Harvest in the early morning when stems are fully hydrated. Strip lower foliage and place immediately in clean, cool water with a floral preservative. Vase life is typically 5–7 days.
For growers building out a diverse cut flower program, verbena pairs beautifully with zinnias, celosia, snapdragons, and lisianthus. See our guide to Growing a Cut Flower Garden from Seed for a full crop planning framework.
Verbena for Pollinator Gardens
Verbena is consistently rated among the top annuals for attracting bees, butterflies, and hummingbirds. The small, tubular florets are perfectly shaped for butterfly feeding, and mass plantings create a reliable nectar source throughout the summer. For growers supplying pollinator garden installations or habitat restoration projects, verbena is an essential component of any seed mix or transplant program.
Pair verbena with salvia, echinacea, and pentas for a multi-season pollinator planting that provides continuous bloom from spring through fall. For more ideas, visit our post on Top Bulk Flower Seeds to Attract Bees and Butterflies.
Growing Tips for Commercial Growers
- Fertilization: Feed with a balanced 20-10-20 fertilizer at 150–200 ppm nitrogen during active growth. Reduce nitrogen and increase potassium as plants approach bloom to promote flower development over foliage.
- Pinching: Pinch transplants once after establishment to encourage branching and a fuller finished plant. This adds 1–2 weeks to production time but significantly improves finished quality.
- Disease management: Powdery mildew is the primary disease concern with verbena. Maintain good air circulation, avoid overhead irrigation, and select mildew-resistant series like Quartz when growing in humid climates.
- Deadheading: For retail and landscape applications, deadheading spent flower clusters extends the bloom period and maintains plant appearance. In cut flower production, regular harvesting serves the same function.

Frequently Asked Questions
How long does verbena take to germinate from seed?
Verbena seeds typically germinate in 14–21 days at soil temperatures of 65–75°F. Pre-chilling seeds in the refrigerator for 5–7 days before sowing improves germination rates significantly, especially for Tuscany and Quartz series varieties.
When should I start verbena seeds indoors?
Start verbena seeds indoors 10–12 weeks before your last expected frost date. This gives transplants enough time to develop a strong root system before going into the garden or containers.
Can verbena be grown as a cut flower?
Yes. Upright verbena varieties like Buenos Aires and Santos Purple produce long stems ideal for cutting. Harvest when about one-third of the florets on a stem are open for the longest vase life of 5–7 days.
What is the best verbena variety for hanging baskets?
Trailing and spreading types like Sweetheart Kisses, Tuscany series, and Quartz Blue are excellent for hanging baskets and containers due to their cascading habit and prolific bloom production throughout the season.
How far apart should verbena be spaced in the garden?
Compact bedding types should be spaced 10–12 inches apart. Spreading and trailing varieties need 14–18 inches to allow full coverage. Upright cut flower types like Buenos Aires perform best at 6–8 inches in production rows.
Does verbena attract pollinators?
Absolutely. Verbena is a top-rated pollinator plant, attracting bees, butterflies, and hummingbirds throughout the season. It is especially effective in mass plantings and pollinator garden designs.
