😼😺 The Story Behind Smokey and Sunshine 🐾
Smokey: Not so fast, genius. Twenty five degrees is not the North Pole. And polar bears and penguins do not share zip codes.
Sunshine: You always pour cold water on my brilliance. Fine. Where do we start?
Smokey: Well, first you go talk to Tatiana. She graduated from the Geography Department. She can explain climate zones. Cherry of the Rio Grande can grow in North Florida, Texas, and similar climates. Let’s master that before we conquer Arctic.
Sunshine: So… Phase One: Geography?
Smokey: Exactly.
Some stories are easier to tell with a little humor. Smokey and Sunshine were never just mascots. They represent the two forces behind every decision we make here: bold ideas and careful reality. One dreams big. The other checks the climate zone map. Together, they remind us that growing plants is part science, part optimism, and always personal. If you have ever wondered why they keep appearing in our newsletters, you can read their full story on the Smokey and Sunshine page. They have been with us longer than most people realize.

Freeze Testing of Grumichama and Cherry of Rio Grande 🍒❄️
When temperatures dropped to 25F, with wind chill near 14F, winter made it clear which tropical trees were truly resilient. Some plants burned back. Tender growth collapsed. But our established Eugenia cherries stood steady. Leaves held. Branches stayed flexible. The canopy remained intact.
Cherry of the Rio Grande (Eugenia aggregata) and Grumichama (Eugenia brasiliensis) are among the most cold-hardy tropical cherries for Southern gardens. Both are native to Brazil and thrive in USDA Zones 9b–11, and even protected 9a sites.
Cherry of the Rio Grande produces dark ruby fruit that ripens almost black, with a rich, full cherry flavor. It flowers early in spring and can fruit well into summer. Mature trees can tolerate brief drops into the low 20s once established. Trees typically grow 8 to 15 feet tall, remain naturally compact, and often begin fruiting within 2 to 3 years.
Grumichama is an evergreen tree known for both beauty and productivity. In spring, it covers itself in white starburst flowers that attract pollinators. Within about four weeks, glossy purple-black fruit develops. Established trees tolerate temperatures into the upper 20s and grow well in the ground or in 5–10 gallon containers. Mature trees can produce hundreds of fruits per season.
Across the Eugenia group, strengths are consistent: early bearing, compact growth, heat tolerance, light freeze endurance, and low pest pressure. They are adaptable to different soils, need modest water once established, and perform in full sun or partial shade. Birds enjoy the fruit, but there is usually plenty to share.
Nutritionally, Eugenia cherries provide Vitamin C, fiber, antioxidants, and notable Vitamin A that supports eye health. They offer sweetness with real dietary value.
In the kitchen, they are simple and rewarding. Cherry of the Rio Grande makes an easy compote. Simmer the fruit with a small amount of water until soft, mash lightly, and spoon over pancakes or warm bread. Grumichama turns into a deep red jam with sugar and lime, or can be blended into a bright spoon drizzle over vanilla ice cream.
Even when not fruiting, both trees remain attractive year-round with glossy evergreen foliage and clean structure. They fit well into edible landscapes, small yards, and container gardens.
Winter will return. The difference lies in planting fruit trees that can handle heat, humidity, and the occasional cold snap. If you are building a food forest for lasting harvests, cold-hardy tropical cherries like Cherry of the Rio Grande and Grumichama deserve a place in your garden.
