2-3", fully-double flowers are a warm apricot color. We chose the Arena series as a later-flowering group 3 (main season) series that can be planted along with an earlier group 2 series, such as the Mariachi series, for a staggered harvest. When planted at the same time, Arenas start to bloom approximately two weeks after Mariachis. Group 3, for late spring, summer, and fall harvest. Lisianthus is also known as prairie gentian, Texas bluebell, and showy prairie gentian. Pelleted seeds.

Harvesting

Arena III Apricot reaches harvest at 155 - 165 days from sowing per Johnny's Selected Seeds. Expect 2-3" at peak. As an annual, harvest continues until frost ends the season.

This is an ornamental variety — not grown for harvest. Enjoy in the garden landscape.

Storage & Preservation

Fresh Arena III Apricot blooms should be stored upright in a clean vase with fresh, cool water (65-72°F) in a cool location away from direct sunlight and ethylene-producing fruits. Change water every 2-3 days. Shelf life is typically 7-10 days indoors. For preservation, try drying by hanging stems upside-down in a warm, dark, well-ventilated space for 2-3 weeks to create dried arrangements. Alternatively, press flowers between absorbent paper under weight for 1-2 weeks for botanical crafts. Silica gel drying preserves color best, taking 3-5 days for this double-form variety.

History & Origin

Arena III Apricot is an F1 hybrid developed through controlled cross-pollination. Listed in the Johnny's Selected Seeds catalog.

Origin: Nebraska south to Texas.

Advantages

+Warm apricot color is distinctive and complements spring-flowering varieties well
+Fully-double flowers provide lush, romantic appearance in floral arrangements
+Two-week bloom delay enables strategic succession planting with earlier series
+Long vase life makes Arena III Apricot commercially viable for florists
+Group 3 timing allows extended harvest through summer and fall seasons

Considerations

-155-165 day timeline requires significant growing space and time investment
-Lisianthus notoriously susceptible to root rot in poorly-drained soils
-Pelleted seeds need careful moisture management to prevent germination failure
-Apricot tone may clash with cooler-colored companion flowers in arrangements

Companion Plants

Marigolds are the most practical companion here — specifically French marigolds (Tagetes patula), which secrete alpha-terthienyl from their roots, a compound that suppresses root-knot nematodes (Meloidogyne spp.) in the surrounding soil. Since Arena III sits in the ground for 5+ months from transplant to cut, anything reducing nematode pressure over that stretch is worth the bed space. Plant them at the border rather than crowded between stems, where they'd compete for light with a crop that needs every hour of sun to push those double blooms.

Sweet alyssum and calendula pull in parasitic wasps and hoverflies that knock back aphid populations before they build up on the buds. Both stay low enough not to shade the Arena III stems. Cosmos works the same way and adds height variety if you're cutting for mixed arrangements — though keep it 12 or more inches away so it doesn't lean in and trap the kind of still, humid air that Botrytis cinerea needs to get started.

Black walnut (Juglans nigra) and eucalyptus are the ones to keep well clear of. Black walnut pushes juglone through its root system continuously, and lisianthus has no tolerance for it. Eucalyptus drops allelopathic compounds in both its leaf litter and root exudates, which can stunt shallow-rooted annuals even before they're established. Sunflowers are a less obvious problem — mildly allelopathic themselves, and they draw thrips, which scar lisianthus petals badly enough to pull them out of any cut-flower grade.

Compete heavily for nutrients and water, may release growth inhibitors

Troubleshooting Arena III Apricot

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

Seedlings collapsing at the soil line, stems look pinched or water-soaked just above the roots

Likely Causes

Damping off — typically Pythium or Rhizoctonia solani, both thrive in cold, wet, poorly drained seedling mix
Overwatering in the first 3–4 weeks after germination

What to Do

1.Ditch any seedling mix that's been sitting wet and start fresh; lisianthus takes 14–21 days to germinate and that extended window means prolonged exposure to wet conditions
2.Water from below using a tray, and let the top half-inch of mix dry slightly between waterings
3.If damping off has already hit part of a flat, pull the affected plugs immediately and don't reuse that mix

Leaves developing gray, fuzzy patches — usually starting on older or damaged tissue before spreading

Likely Causes

Botrytis cinerea (gray mold) — almost always triggered by high humidity, poor airflow, or dense planting

What to Do

1.Space transplants at least 9–12 inches apart so air can move between stems
2.Water at the base, not overhead, and do it early enough in the day that foliage dries before evening
3.Strip off any dead or damaged leaves as soon as you see them — Botrytis moves fast on compromised tissue

Plants barely growing, leaves are small and pale green, stems look thin even 6–8 weeks after transplant

Likely Causes

Nitrogen deficiency in low-organic or heavily leached soil
Root-knot nematodes (Meloidogyne spp.) restricting uptake — common in sandy soils

What to Do

1.Side-dress with a balanced slow-release fertilizer (something in the 10-10-10 range) and give plants a good deep soak to move it into the root zone
2.Pull a plant and check the roots for galls — if they're present, move lisianthus to a different bed next season and consider a cover crop of 'Calypso' marigolds in the affected area to suppress nematode populations
3.Test your soil before the next planting; lisianthus wants pH around 6.5–7.0 and won't feed well outside that range

Frequently Asked Questions

How long do Arena III Apricot flowers last in a vase?▼

Arena III Apricot lisianthus typically lasts 7-10 days in a vase with proper care. Keep stems in fresh, cool water (65-72°F), change water every 2-3 days, and remove lower foliage to prevent bacterial growth. Placing the vase in a cool location away from direct sunlight and ethylene-producing fruits will extend vase life.

Is Arena III Apricot a good choice for beginner flower growers?▼

Yes, Arena III Apricot is excellent for beginners. Classified as an Easy difficulty variety, this hybrid lisianthus is forgiving and reliable. It thrives in full sun to partial shade with minimal special care. The pelleted seeds are easy to handle, and as a Group 3 main-season variety, it provides flexibility in planting schedules for staggered harvests.

Can you grow Arena III Apricot in containers?▼

Yes, Arena III Apricot can be grown in containers. Use well-draining soil and ensure pots have adequate drainage holes. Container growing allows better control over soil conditions and moisture. Choose containers at least 6-8 inches deep, and place them in locations receiving 4-6+ hours of sunlight for optimal flowering and bloom quality.

When should I plant Arena III Apricot lisianthus seeds?▼

Start Arena III Apricot seeds indoors 6-8 weeks before your last frost date. This Group 3 main-season variety requires time to develop before outdoor planting. Transplant seedlings outdoors after frost danger passes. With a 155-165 day harvest window, early seeding ensures blooms arrive in late spring through fall, making it ideal for summer and fall flower harvests.

What makes Arena III Apricot different from Mariachi lisianthus?▼

Arena III Apricot is a Group 3 (main-season) variety that flowers approximately two weeks later than the Group 2 Mariachi series. This timing difference is intentional for staggered harvests when both are planted simultaneously. Arena III produces 2-3" fully-double apricot blooms, offering later flowering and extended season coverage compared to earlier-blooming Mariachi varieties.

What does Arena III Apricot look like when fully bloomed?▼

Arena III Apricot displays 2-3 inch, fully-double flowers in a warm apricot color. The blooms feature dense, layered petals creating a full, rounded appearance typical of double-form lisianthus. This showy flower form makes it particularly valuable for cut flower arrangements and garden displays where impressive floral impact is desired.
