Snapdragons (Antirrhinum majus) add vibrant color to fall and winter gardens in North Florida with their wide range of hues. Colors include red, orange, yellow, and maroon. Their growth varies; tall varieties reach 2–3 feet, intermediates 1–2 feet, bedding types 6–15 inches, and rock garden hybrids about 6 inches. Dark-colored flowers often have reddish stems, while pale blooms grow on light green stems. Snapdragons’ warm-colored flowers stand out in garden beds, especially when paired with white flowers, enhancing their red, orange, and maroon tones. Their fine-textured foliage contrasts nicely with large-leaved plants and compact shrubs.
Though not native to North America, they are widely cultivated and are not considered invasive. Snapdragons are versatile and ideal for mass plantings, containers, cut flowers, and edging. They are generally available within their hardiness range, making them a popular gardener choice.
Caring for Snapdragons requires minimal work. They thrive in slightly acidic garden soil but struggle in unamended clay. Therefore, ensuring the soil remains acidic is key to their survival. They require full sun and moist soil. After the first bloom, cutting plants back to five or six nodes encourages a second flowering. Also, fertilizing at bud formation improves growth.
You can increase numbers through propagation. Propagation can be done through seeds or cuttings. Seeds germinate in 10–14 days at 70°F and should not be covered with soil. Prechilled seeds germinate best. Pinch seedlings with two to three leaf sets, except for dwarf varieties. Plant in fall for winter blooms in zones 9–11. In zone 8b and south, snapdragons may survive mild winters. Space plants 6–10 inches apart.
Pests and Diseases
Aphids: Feed on young growth, weakening plants.
Greenhouse leaf tier: Chews and webs leave; pesticides are ineffective once leaves roll.
Mites: Cause bronzed, stippled foliage, especially in hot weather.
Common Diseases
Rust: Brown pustules with yellowed leaf tissue; use proper spacing and resistant varieties.
Anthracnose: Causes sunken spots on stems and yellowing leaves; destroys infected plants.
Gray mold: Leads to wilting and stem browning; worsens in wet conditions. Remove infected stalks.
Stem rot: Cottony growth near soil line; infected plants should be removed.
Snapdragons offer rich color, versatility, and seasonal interest in gardens, making them a valuable addition for novice and experienced gardeners.

Growing pansies in North Florida is a rewarding experience, as these resilient flowers thrive in cooler temperatures. As I walked up to our front office after the ice had melted away, I was amazed to see their vibrant blooms still standing strong, displaying their cheerful faces despite the harsh conditions of the January 2025 winter storm. Their endurance is a testament to their hardiness, making them a perfect choice for winter gardens. Here’s a guide to help you successfully cultivate pansies in our region.
Best Planting Time
Pansies thrive in cooler weather, making fall (October–November) the ideal time to plant them. Once established, they will provide stunning blooms throughout the winter and into early spring. While they can tolerate mild frosts, Florida’s summer heat is too intense for them, so they are best treated as a seasonal flower.
Choosing the Right Variety
Not all pansies are well-suited for Florida’s fluctuating temperatures. To ensure a successful and long-lasting display, select heat-tolerant varieties such as Majestic Giants, Matrix, or Delta Series, which are known for their resilience and vibrant blooms.
Delta Series – A popular choice for its bold yellow, purple, and blue flowers. This variety is highly valued for its disease resistance, vigorous growth, and ability to withstand both cold and mild heat.
Majestic Giants – A classic pansy cultivar known for its large, eye-catching blooms in a variety of colors and patterns. These compact plants thrive in both container gardens and mass plantings.
Matrix Series – This variety produces dense, bushy plants with large flowers, making it an excellent choice for creating colorful, impactful displays in both garden beds and containers.
By choosing the right variety, you can ensure your pansies thrive throughout the cooler months, bringing beauty and color to your landscape.
Sun and Soil Requirements
For the healthiest plants, provide full sun to partial shade, with at least 4–6 hours of direct sunlight each day. Pansies prefer well-draining soil rich in organic matter, with a slightly acidic to neutral pH (5.5–6.5). Improve your soil’s structure by adding compost or peat moss, which enhances both drainage and nutrient content.
Watering & Care
Maintaining proper moisture levels is key to keeping pansies healthy. Water them 2–3 times a week, ensuring the soil remains moist but not soggy. A layer of mulch will help retain moisture and reduce weed growth. To encourage continuous blooms, apply a balanced, slow-release fertilizer every few weeks and remove spent flowers (deadheading) to keep plants looking fresh and vibrant.
Common Challenges & Solutions
Despite their hardiness, pansies can face a few challenges:
Heat Sensitivity: If temperatures rise unexpectedly, pansies may wilt. Providing afternoon shade can help them cope.
Pests: Keep an eye out for aphids, slugs, and caterpillars. Use insecticidal soap or remove pests by hand to prevent damage.
Fungal Diseases: Avoid overhead watering to prevent root rot and mildew. Ensuring good air circulation will also help reduce disease risks.
Spring Transition
As spring temperatures climb, pansies will naturally begin to decline. To maintain a colorful garden, consider replacing them with heat-tolerant flowers such as zinnias, marigolds, or vincas, which can handle Florida’s warm and humid conditions.
Their cheerful, expressive blooms make them a wonderful choice for adding color and charm to your landscape. Happy planting!
Planting annuals is a great way to add color and texture to the landscape. Annuals can provide an added visual component to the garden regardless of if they’re planted in the ground or in containers, or even better—both. An annual plant completes its life cycle (growing, flowering, seed set, and death) in a single growing season. Annuals can stay in good health and last longer if they are pruned back when they get leggy and by pinching off any fading flowers (deadheading).

Please note the suggested planted dates in this guide are based on average monthly temperatures, but every year is different. Some years we may have a late frost around Easter, other years we won’t have a cold front after February.

Two years ago, the Escambia Master Gardener Volunteers were gifted with the flowering perennial Sweet Almond bush (Aloysia virgata). It has quickly become a favorite plant of volunteers and garden visitors due to its many attractive features.
Although, Sweet almond bush is not a Florida native, it is Florida-friendly plant for zones 8b -10b. Plants grow very large, from 6-10 feet with branching that can spread out in all directions. In North Florida, plants can be damaged by a freeze but either return from the base or from growing points higher on branches.
One of the best features are the fragrant white flowers spikes that will be present late spring through fall. Many types of pollinating insects will be attracted to the flowers, although sometimes flowers are too high on the plant for many of us to get a good look at pollinator details.

We have plants both in full sun and partial shade that are performing well in the Escambia Demonstration Gardens. Plants do receive water when rainfall is lacking for about 5-7 days (or all of August this year in the Northwest Panhandle). You can shape your plant with a little light pruning during the growing season to keep branches a little more in bounds. Don’t forget to start a few new plants from these cuttings and then share a low maintenance plant with your neighbors.
