Quick answer: Snapdragon (Antirrhinum majus) can grown in June Park, FL (USDA zone 10a, Subtropical Southeast). Plant indoors 8 weeks before the last frost on Feb 15. Use a 2-gallon, 8" deep container with rich; well-drained; loamy with compost, pH 6.2–7. Water every 1-2 days at peak summer — June Park's humid subtropical climate keeps humidity high — watch for fungal pressure. Matures to 30" tall × 12" wide.
Why grow Snapdragon in June Park?
June Park sits in USDA zone 10a (heat zone 8) with a Cfa (humid subtropical) climate (Köppen-Geiger / VU Wien) — Subtropical Southeast. Summer highs reach 90°F (NOAA NCEI) and winter lows fall to 52°F, at 43ft elevation (USGS). Snapdragon prefers USDA zones 7–11, killed below 20°F. The zone fits comfortably — the challenge here is humid-summer disease pressure, not temperature. Surrounding metros — West Melbourne, Melbourne, and Indialantic — share the same climate, so this guide largely applies to them too.
The 295-day growing season (Feb 15 to Dec 10) gives you plenty of runway for snapdragon, which take 70–90 days to mature. June Park averages 2700 hours of sunshine annually with 100 chill hours per winter — snapdragon only need 6–8 hours daily, so light is never the problem. The game in June Park is managing the humid August disease wave.
Metro-wide climate notes: West Melbourne and Melbourne sit in the same zone 10a humid subtropical basin as June Park, while Indialantic at slightly higher elevation runs 2-3°F cooler in winter. Palm Bay in the lower valley shares June Park's frost dates almost exactly. The snapdragon growing strategies in this guide apply across the entire metro.
Also known as: Common Snapdragon; Garden Snapdragon; Dragon Flower · Family: Plantaginaceae · Annual ornamental.
When to plant in June Park
June Park growers get one long snapdragon window from spring transplant through the first fall frost, with the catch that midsummer humidity raises the disease bar.

Snapdragons are a medium feeder. Use a 10-10-10 (balanced macronutrients) fertilizer once flowers appear. In containers, nutrients leach with every watering — feed weekly at half strength rather than monthly at full.
Sun
Snapdragons need 6–8 hours of Full Sun. In June Park, morning sun with light afternoon protection during heat waves keeps plants productive without scorching.
Pests & diseases in June Park
Priority pests (June Park + Snapdragon intersection)

Common June Park snapdragon mistakes
- Covering seed (needs light).
- planting too late in spring.

- skipping pinching produces leggy plants.
- Overhead watering at sundown — humid June Park air keeps leaves wet overnight, opening the door to blight.
- Skipping the open-canopy prune — June Park's summer dew points punish dense foliage.
- Ignoring stink-bug scouting in late May — populations explode silently and pock the fruit overnight.
