Eustoma grandiflorum
Wikimedia Commons via Eustoma russellianum
Light blush pink, 2-3", fully-double flowers. 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.

Complete Growing Guide
Light blush pink, 2-3", fully-double flowers. 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. According to Johnny's Selected Seeds, Arena III Baby Pink is 155 - 165 days to maturity, annual, hybrid (f1). Notable features: Greenhouse Performer, Use for Cut Flowers and Bouquets.
Light: Full sun (6 or more hours of direct sunlight a day), Partial Shade (Direct sunlight only part of the day, 2-6 hours). Soil: Loam (Silt), Sand. Drainage: Good Drainage, Moist. Height: 1 ft. 0 in. - 3 ft. 0 in.. Spread: 0 ft. 9 in. - 1 ft. 0 in.. Maintenance: High. Propagation: Seed.
Harvesting
Arena III Baby Pink 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-cut Arena III Baby Pink stems last 7-10 days in a clean vase with cool water and floral preservative (or a homemade mix: one tablespoon sugar and a few drops of bleach per quart). Change the water every 2-3 days, re-cut stems at a 45-degree angle, and keep the vase away from ripening fruit and direct sunlight.
For extended storage before arranging, place cut stems in a cool room (50-60°F) or refrigerator in clean water. They'll hold for 2-3 weeks under refrigeration, making them suitable for advance event preparation.
Lisianthus doesn't freeze well intact, but you can dry flowers for long-term preservation: hang bundles upside-down in a dark, well-ventilated room for 2-3 weeks, or use silica gel (bury flowers in silica gel for 5-7 days). Dried Arena III blooms retain their pale pink color and delicate texture, making them excellent for dried arrangements or pressed-flower crafts. Store dried flowers in airtight containers in cool, dry conditions to prevent mold and color fading.
History & Origin
Arena III Baby Pink is an F1 hybrid developed through controlled cross-pollination. Listed in the Johnny's Selected Seeds catalog.
Origin: Nebraska south to Texas.
Advantages
- +Staggered harvest timing enables continuous blooms with earlier Mariachi series plantings
- +Fully-double flowers provide luxurious, multi-petal blooms ideal for high-end floral arrangements
- +Light blush pink color offers versatile, romantic aesthetic for diverse market demands
- +Easy difficulty rating makes Arena III accessible to novice and experienced growers
- +Extended 155-165 day season allows flexible planting windows for spring through fall production
Considerations
- -Long growing cycle requires significant greenhouse space and extended crop commitment period
- -Fully-double flowers may shatter or bruise more easily than single-petal varieties during handling
- -Lisianthus demands precise water management; overwatering quickly causes root rot and plant loss
- -Pelleted seeds require careful sowing precision; poor germination results from improper moisture control
Companion Plants
Marigolds (Tagetes patula in particular) are the most practical companion here. They emit thiophenes from their roots, which suppress soil nematodes — not a dramatic fix, but a measurable one over a full season. The dense flower heads also draw whiteflies and thrips away from lisianthus blossoms, giving you a sacrificial crop you can monitor and treat without spraying your cut flowers. Plant them 12 inches off to the side rather than directly interplanted, so they don't compete for water.
Sweet Alyssum and Lobelia both pull their weight as low-growing, shallow-rooted plants that don't compete for the same soil depth as lisianthus roots. They attract parasitic wasps and hoverflies — the kind that lay eggs near aphid colonies and let the larvae handle pest control. They also fill in bare soil between plants, which cuts down on the rain-splash transmission that gives gray mold (Botrytis cinerea) its opening during wet stretches. Basil offers some pest confusion effect, though its real value here is that it shares the same "consistent moisture, good drainage" preference — you're not fighting two different watering schedules in the same bed.
Fennel belongs nowhere near this planting. Its root exudates — primarily anethole and related phenolic compounds — stunt or kill nearby ornamentals, and lisianthus is not especially tolerant of chemical interference at the root zone. Brassicas are a subtler problem: they're heavy feeders that draw down nitrogen quickly and can harbor aphid populations that migrate onto neighboring plants once the brassica crop declines.
Plant Together
Marigolds

Lobelia
Similar growing requirements and provides complementary blue color contrast
Bacopa

Whitefly, spider mite, thrips
Diseases
Powdery mildew, gray mold (Botrytis), damping off, root rot
Troubleshooting Arena III Baby Pink
What you'll see, why it happens, and what to do about it.
Seedlings collapsing at the soil line within the first 2-3 weeks after germination
Likely Causes
- Damping off — typically Pythium or Rhizoctonia fungi thriving in overwatered, poorly drained seedling mix
- Trays kept too wet with insufficient airflow around the stem base
What to Do
- 1.Water from the bottom only, and let the top inch of mix dry slightly between waterings
- 2.Run a small fan near your seedling trays for 1-2 hours a day to keep surface moisture down
- 3.If damping off has already hit a cell pack, pull the affected seedlings and don't reuse that mix — it's contaminated
White powdery coating on leaves and stems, usually appearing after plants are 6-8 weeks old
Likely Causes
- Powdery mildew (Erysiphe cichoracearum or related species) — triggered by warm days, cool nights, and poor air circulation
- Crowded spacing under 12 inches that traps humidity around the foliage
What to Do
- 1.Space plants at least 12 inches apart — 15 is better in humid climates — to get air moving between them
- 2.Apply a potassium bicarbonate or neem oil spray at first sign; repeat every 7-10 days
- 3.Avoid overhead watering in the evening; water at the base in the morning instead
Leaves stippled silver-gray with tiny bronze specks, flowers distorted or streaked, around mid-season
Likely Causes
- Thrips (Frankliniella occidentalis) — they rasp the leaf surface and feed inside flower buds
- Spider mites (Tetranychus urticae) — also cause stippling, especially in hot, dry spells above 85°F
What to Do
- 1.Hold a white sheet of paper under a stem and tap it — if tiny moving specks fall out, confirm the pest before treating
- 2.For thrips, spray spinosad every 5-7 days for two cycles; for spider mites, try insecticidal soap or a strong water blast to knock them off
- 3.Keep plants consistently irrigated — mite populations spike on drought-stressed lisianthus faster than on most other cut-flower crops
