Completely unique, soft peachy-pink color - a standout in our trials. Single-stem/column-type stock for one-cut harvest. Sturdy, upright stems are comparable to the Iron series. Double-flowering plant selection: Plants are selectable for double-flowering blooms. Without selection your plants will produce approximately 55% double-flowering plants and 45% single-flowering plants. Double-flowering plants will display a lighter leaf color at the seedling stage after a cold treatment. You might notice that some seedlings will present the lighter color leaves, even without a prescribed cold treatment. NOTE: This variety produces one flowering stem per plant. Pinching is not advisable as it will terminate flowering. Edible Flowers: The peppery, clove-like flavor of the flowers lends itself well to use as a garnish on salads, desserts, and drinks.

Succession Planting

Stock doesn't produce continuously the way a pepper does — each plant sends up its main spike and that's largely the show. Succession planting is your best tool for a longer cut-flower season. In zone 7, start seeds indoors every 3 weeks from February through March, then transplant in waves from April through early May. Stop once daytime highs are consistently hitting 80°F; stock sets buds in cool weather, and sustained heat above that threshold causes plants to bolt past flowering almost entirely.

A fall planting is worth doing too. Direct sow in late August — right around the end of the month — to catch the cooler stretch from October into November. These fall rounds often produce the best stems of the year, since the 90-to-105-day window lands in mild conditions without summer cutting things short.

Harvesting

StoX® Champagne reaches harvest at 90 - 105 days from sowing per Johnny's Selected Seeds. As an annual, harvest continues until frost ends the season.

Seeds will ripen in August and September.

Harvest time: Fall

Storage & Preservation

Fresh stock flowers should be stored upright in a vase with cool water at 35-40°F in the refrigerator, changing water every 2-3 days for optimal vase life of 10-14 days. For preservation: (1) Air-dry by hanging upside-down in a cool, dark, well-ventilated space for 2-3 weeks—ideal for dried arrangements; (2) Press individual florets between parchment paper under weight for 1-2 weeks for crafts and botanical displays; (3) Freeze petals in ice cube trays with water for later use as edible garnishes, keeping frozen up to 3 months.

History & Origin

StoX® Champagne is open-pollinated, meaning seed saved from healthy plants will produce true-to-type offspring. Listed in the Johnny's Selected Seeds catalog.

Origin: The Coast of Europe from Spain to Greece.

Advantages

  • +Distinctive soft peachy-pink color provides striking visual appeal in arrangements
  • +Single-stem harvest design maximizes efficiency and minimizes labor costs
  • +Sturdy upright stems rival Iron series quality for professional use
  • +Selectable double-flowering trait allows growers to choose preferred bloom style
  • +Edible flowers with peppery clove flavor add culinary versatility

Considerations

  • -No pinching allowed limits plant structure customization for growers
  • -Unpredictable flowering ratio requires careful selection during seedling stage
  • -Single stem per plant yields lower cut volume compared to branching varieties
  • -Cold treatment causes inconsistent seedling leaf coloration making identification difficult

Companion Plants

Marigolds earn their spot here — they suppress soil nematodes and their scent confuses the aphids that stock reliably attracts. Sweet alyssum along the bed edges pulls in parasitic wasps and hoverflies, which keeps soft-bodied pest pressure manageable through the 90-to-105-day run. Lavender shares stock's preference for sharp drainage without competing for root space, making it a low-maintenance neighbor. Skip black walnut entirely — juglone from the roots will stunt or kill Matthiola, and around here in the Georgia Piedmont, old walnuts near fence lines aren't unusual. Fennel goes on the avoid list too; it's broadly allelopathic and tends to suppress most flowering annuals planted within a few feet.

Troubleshooting StoX® Champagne

What you'll see, why it happens, and what to do about it.

Gray, powdery coating on leaves and stems, usually appearing first on older growth as temperatures cool in fall

Likely Causes

  • Powdery mildew (Erysiphe cichoracearum) — favored by warm days and cool nights with poor air circulation
  • Crowded spacing under 12 inches that traps humidity around foliage

What to Do

  1. 1.Thin plants to at least 12 inches apart if you haven't already — airflow matters more than anything else here
  2. 2.Spray affected foliage with a diluted neem oil solution (2 tbsp per gallon of water) every 7 days until symptoms stop spreading
  3. 3.Water at the base, not overhead — wet foliage at night is the fastest way to make this worse
Plants wilting and collapsing at the soil line, stem base dark and mushy, even with adequate water

Likely Causes

  • Botrytis stem rot (Botrytis cinerea) or Phytophthora root rot — both thrive in waterlogged, poorly draining soil
  • Overwatering combined with heavy clay soil that holds moisture too long

What to Do

  1. 1.Pull and trash the affected plant immediately — don't compost it
  2. 2.Check drainage in that bed; if water pools for more than 30 minutes after rain, amend with coarse sand or perlite before replanting
  3. 3.Hold off watering neighboring plants until the top inch of soil is dry to the touch

Frequently Asked Questions

How long do StoX® Champagne stock flowers last in a vase?
With proper care—fresh water, cool temperatures (35-40°F), and removal of lower foliage—these stock flowers typically last 10-14 days. Changing water every 2-3 days and re-cutting stem ends every few days extends vase life. The sturdy, single-stem nature of this variety makes it particularly good for long-lasting cut arrangements.
Is StoX® Champagne stock suitable for beginner flower growers?
Yes, absolutely. This variety is rated 'Easy' and is ideal for beginners. It requires full sun to partial shade (4-6+ hours), is straightforward to grow, and produces reliable blooms. The key is not to pinch the plant, as it produces only one flowering stem. Once established, it needs minimal intervention.
What does StoX® Champagne stock taste like?
The flowers have a distinctive peppery, clove-like flavor profile. This edible variety works wonderfully as a garnish on salads, desserts, and drinks. The spicy-sweet notes add an interesting culinary element and visual appeal to plates and beverages.
Can you grow StoX® Champagne stock flowers in containers?
Yes, stock flowers grow well in containers. Use well-drained potting soil, ensure 4-6+ hours of sunlight daily, and maintain consistent moisture. Container growing is excellent for managing plant spacing and creating focal points in patio displays. Sturdy, upright stems support themselves even in containers.
When should I plant StoX® Champagne stock for summer blooms?
For summer blooms, start seeds indoors 6-8 weeks before your last frost date. Stock flowers typically require 90-105 days to harvest. Alternatively, direct sow after the last frost. This timing ensures plants are established and flowering during warm months.
What is the difference between the double and single-flowering plants on this variety?
StoX® Champagne naturally produces approximately 55% double-flowering (more petals, fuller blooms) and 45% single-flowering plants. Double-flowering plants display lighter leaf color at seedling stage after cold treatment, making them selectable. Both types are attractive; choose based on your preferred bloom fullness.
