Zinnia elegans × Zinnia angustifoliaZinnia / Profusion is a annual herb maintained at Green Grass Grove. It typically reaches 12–18 inches by 18–24 inches and is managed under Live Oak conditions for seasonal flowering, pollinator support, and nursery display. The profile emphasizes warm-season annual suited to hot sunny beds and preserves the existing specimen identity.
Botanical Overview
Zinnia / Profusion is a annual herb maintained at Green Grass Grove. It typically reaches 12–18 inches by 18–24 inches and is managed under Live Oak conditions for seasonal flowering, pollinator support, and nursery display. The profile emphasizes warm-season annual suited to hot sunny beds and preserves the existing specimen identity.
Why We Feature This Specimen
Follow Zinnia / Profusion through the Green Grass Grove living collection as it moves from seedling or vegetative establishment into flowering and habitat use. This record connects public botanical interpretation with real nursery, climate, scouting, and accession observations.
Climate & Protection
Cold protection trigger: Begin cold protection below 50 °F. The cold-damage threshold is the lower temperature where injury becomes likely, not the recommended waiting point.
Sun / Light: Full sun
Warm-season annual suited to hot sunny beds. Profusion types generally maintain flowering through heat better than tall Z. elegans cultivars, but frost ends growth and prolonged wetness can still cause decline.
Heat-zone and verification notes
Not assigned; use crop-specific heat and seasonal guidance.
Planting & Seasonal Guide
Starting & Germination Methods
Seed Sowing
Seed sowing is the umbrella operational method for placing botanical seed into a germination environment. It includes selection of containers or beds, medium, depth, spacing, moisture, temperature, light,…
Open Full Method ↗Direct Sowing
Direct sowing is the establishment of plants by sowing seed outdoors or into the final production bed rather than transplanting nursery-grown seedlings. It is a complete site operation…
Open Full Method ↗Warm-season annual suited to hot sunny beds. Profusion types generally maintain flowering through heat better than tall Z. elegans cultivars, but frost ends growth and prolonged wetness can still cause decline. Establish during the season that avoids the profile's main heat or freeze stress, and record local survival rather than treating the recommendation as universal.
Spacing: 12–18 inches
Planting Depth: Sow or set at the species-appropriate depth; keep woody root flares and herbaceous crowns at grade and do not bury stems deeply.
Pollination: Allow selected healthy plants to flower for pollinator observation and seed records. Preserve mixture or cultivar identity when saving seed.
Water, Soil & Nutrition
💧 Water & Moisture
Irrigate deeply after the upper surface begins to dry. Compact canopies need spacing and root-zone watering to reduce persistent humidity around foliage.
North Florida humidity increases foliar and fruit disease risk for Zinnia / Profusion. Space and train the plant for rapid drying, use root-zone irrigation, and inspect after multi-day rain. Dense canopies, wet flowers, and damaged fruit should not remain as inoculum.
🌱 Soil & Growing Media
Preferred pH: 5.80 to 7.50
↘ Drainage & Root-Zone Behavior
✦ Nutrition & Deficiency Checks
Use soil testing and moderate balanced fertility for Zinnia / Profusion. On sandy soil, split applications to reduce leaching and avoid excessive nitrogen that causes weak stems, delayed flowering, poor fruit quality, or pest-prone growth. Maintain the profile pH range before diagnosing micronutrient deficiency.
For Zinnia / Profusion, pale or distorted growth may reflect nitrogen, magnesium, iron, or other nutrient limitations, but root injury, high pH, drought, waterlogging, and cold can look similar. Inspect roots and moisture first and use soil or tissue testing for persistent symptoms.
Growth, Maintenance & Harvest
Maintenance & Pruning
Pinch or deadhead Zinnia / Profusion according to its growth habit to promote branching and continued bloom. Remove storm-broken, diseased, or collapsed stems with sanitized tools. Avoid heavy cutting when foliage is wet, and leave selected seed heads only where reseeding and accession control are acceptable.
Harvest or Observation
For Zinnia / Profusion, harvest flowers or flowering stems according to the intended cut-flower, seed, or interpretation use. Cut during the cool part of the day with sanitized tools, remove damaged foliage, and place stems in clean water promptly. For seed saving, retain representative disease-free plants and dry mature heads under cover before labeling and storage.
Storage & Preservation
Use fresh cut material promptly. Dry mature seed thoroughly in shade with airflow, label by profile and harvest date, and store cool and dry. Do not save seed from diseased, hybrid-uncertain, or containment-restricted plants without a specific protocol.
Harvestable Plant Parts & Uses
For Zinnia / Profusion, harvest flowers or flowering stems according to the intended cut-flower, seed, or interpretation use. Cut during the cool part of the day with sanitized tools, remove damaged foliage, and place stems in clean water promptly. For seed saving, retain representative disease-free plants and dry mature heads under cover before labeling and storage.

Open Full Method ↗Aquaponics, Hydroponics & Aeroponics
Aquaponics
Can be tested in media beds, but vigorous flowering annuals need stable support, adequate potassium and calcium, and dry foliage.
Hydroponics
- Target pH5.8–6.5
- Target EC1.2–2.0 mS/cm
Hydroponic trials are possible but less practical than clean raised beds or containers for habitat and cut-flower production.
Aeroponics
No profile-specific operating notes have been recorded.
Pests, Diseases, Safety & Toxicology
Scout Zinnia / Profusion for aphids, mites, whiteflies, leaf miners, caterpillars, beetles, and slugs according to season and growth stage. Preserve pollinators and natural enemies.
Monitor Zinnia / Profusion for damping-off, root or crown rot, powdery mildew, leaf spots, and stem blights. Space plants for airflow, water at the root zone, and remove symptomatic material after diagnosis.
Manage Zinnia / Profusion for its intended pollinator, herb, or native-plant role: establish in suitable soil, prevent crowding, deadhead or retain seed according to the conservation goal, and monitor self-seeding or rhizome spread.
Key problems for Zinnia / Profusion include aphids, thrips, powdery mildew, bacterial leaf spot, and climate or water stress described in this profile. North Florida storms can lodge stems, saturate roots, bruise fruit, or spread leaf disease. Confirm symptoms before treatment, because nutrient imbalance, heat, freeze injury, and root damage can mimic infection.
