Hot novelty plant for hot Arizona

Q: What plants would you recommend for very hot and dry spot in front of my house that gets full sun all day long? I live in AZ, we recently had a couple good rains but this is going to be it for a long time. It gets so hot during the day that every plant I tried didn't make it. We have a few nice orange trees growing well but I would like to plant something compact, colorful and hopefully fragrant if there is such plant.

A: There is a perfect small size plant for you that is extremely fragrant and yet will be thriving in these conditions. It is the famous Jasmine sambac. It will appreciate dry air of Arizona and will bloom profusely for you in full sun or in partial shade. It doesn't mind heat at all.

For colorful accents, a proven winner is Crown of Thorns - Euphorbia millii. New giant size flower varieties were recently selected in Thailand, and we just received a great selection, look at the colors! These plants don't mind hot sunny location at all. The more sun, the better the bloom! Small plants need regular watering until establish, then once they start developing, they will require less water.

Giant Euphorbia flowers from Thailand are 4-5 times bigger than regular flower euphorbia. Diameter of the flower is around 2". Compare giant flower to normal size - picture on the right.

Growing Exotic Adeniums

Exotic varieties of Desert Roses. Adeniums have many spectacular hybrids. The basic culture is very similar to orchids. A small pot with excellent drainage is a must. Adeniums do not like both over-watering or drying-out. There is a secret how to create a large swollen caudex: raise the plant a bit every time you re-pot it, so that the upper part of roots will be a little exposed. The plant will form more roots that will go down.

To make your plant develop a large swollen base/trunk, you'll need a good quality fertilizer. Fertilizer requirement for swelling up trunks is also used to increase flowering. It shouldn't be too high in nitrogen, the middle number should be the highest (similar to 10-50-10). Never apply fertilizer directly on roots and do not liquid feed when a plant is thirsty: always water first slightly to avoid root burn and leaf drop. Do not wet leaves. Adeniums need lots of light for heavy flowering.

Most hybrids and species start blooming in the spring when the conditions are warm and days get longer, and continue blooming through the fall and winter in warmer climates. Adeniums like a neutral to hard water. Acidic water tends to sour the soil too fast and may cause root rot. Water plants preferably in the early morning, and allow them to drink up throughout the day. Watering can be done daily to every few days. Never allow your plants to sit in a saucer of water, but don't let them to dry out too often - this causes adeniums to go into early dormancy.

Planting instructions for bare-rooted succulent plants. Position the plant in a pot, size of root system. Use only well-drained soil with high content of Perlite and/or sand (cactus mix can be used), water once and keep in warm (75-80F) place in filtered light. Do not water again until soil dries on surface. Once the plant is established and starts growing new leaves (may take a few weeks), gradually move it into brighter light. Then you can start fertilizing it.

☃️ Winter is choosing season

 Christmas  living  room  with  tropical 
 plants.

Smokey: "December is for planning, not planting."
Sunshine: "Gift card now. Perfect plants later."
Smokey: "You surprise me sometimes. Must be the donuts."

This time of year always feels special to us. The days are shorter, the garden slows down, and we finally have a moment to pause, look at our wish lists, and dream a little about spring.

As gardeners, we know winter is not really planting season. It is choosing season.

It is when ideas take shape. When we think about what we want to grow next, what we want to add, and what we want to do differently when warm days return. That is why, in winter, the best plant gift is not a plant itself. It is the promise of one.

Cold weather and holiday shipping can make winter plant deliveries stressful, especially for tropical plants traveling north. A gift card lets plants wait for the right moment, and lets the gardener enjoy the fun part now: planning, choosing, and imagining.

It also solves something we all know too well. Every gardener is wonderfully different. Some dream of fruit trees, others of flowers, rare collectors, or easy growers. Some plant in containers, some in the ground. Guessing is hard. A gift card lets them choose exactly what fits their garden and their vision.

🎁 Holiday Gift Card Bonus

To make the season a little brighter, we are offering a holiday gift card bonus through 12/31/2025.

When you purchase a gift card, we add 15% extra value. Just add Christmas greeting in gift card message field. For example, a $100 gift card becomes $115 to spend.

The bonus value is not valid with other promotions or discounts. Gift cards cannot be used to purchase other gift cards. Bonus value is added at the time of purchase.

❄️ The Hardiness Report: February 2026 ❄️

🐾 Smokey & Sunshine’s real-world survival data from our Sebring, Florida Research Gardens. Smokey analyzed the data. Sunshine just stayed happy. Here is what they found.

Macadamia  tree  surviving  25F  freeze  as  Smokey  inspects  leaves  and 
 Sunshine  holds  steaming  coffee  in  frosty  garden.
Sunshine: Twenty five degrees. Wind chill fourteen. And it is still standing... like nothing happened?
Smokey: This is macadamia strength.
Sunshine: I should put a macadamia nut in my coffee and borrow some of that strength.
Smokey: Do not get too nutty yet. It still needs curing and cracking.

📊 Weather Data – February 1–6, 2026

Sebring, Florida – 132 years of recorded observations
This was not a light frost. It was a prolonged, windy, penetrating hard freeze.

  • 🌡 Minimum temperature: 25F
  • ❄️ Wind chill: 14F
  • ⏳ Duration: 3 nights of 8–10 hour hard freeze
  • ☀️ Daytime temperatures: around 50F for 7 days
  • 🌀 Wind: sustained 20 mph, gusts 40–50 mph

While all our plants in pots were protected in greenhouses, our in-ground plantings faced the freeze outdoors. We covered what we could. Even so, some plants were damaged, some died, and some surprised us by surviving.

In the next few newsletters, we will share the real survivors - the plants that proved themselves in the ground, under real conditions. Smokey and Sunshine have been out in the fields assessing the damage from the February 1–6 freeze. While many plants struggled, the Macadamia proved to be a true standout. This is how we grow them to handle the tough years.

Why does this matter? Because we have gotten used to warm winters, and this freeze was a rude awakening. Not everyone lives in Miami. If you garden in places where a real cold event can happen, you have to be prepared - and you have to plant what can take it.

🌰 Macadamia: Freeze Tested and Standing

 February  2026,  showing  healthy  foliage.

3 year old macadamia tree after 3 nights of hard freeze in February 2026 - standing strong.

When temperatures dropped to 25F with wind chill near 14F, our established macadamia trees remained upright, green, and structurally intact. Leaves held. Branches stayed firm. No collapse, no panic.

That is not luck. That is macadamia hardiness.

Often considered a "tropical luxury nut," macadamia proved it can handle more than many gardeners expect. In USDA Zones 9b-11, with proper drainage and site selection, it is not just ornamental - it is a long-term food tree with real resilience.

In a winter that reminded us not to take warmth for granted, macadamia earned its place on the survivor list.

The nut itself is famous for its strength. The shell is among the hardest in the nut world, requiring serious pressure to crack. Inside, the kernel is creamy, buttery, rich, and deeply satisfying. High in monounsaturated fats and naturally low in sugar, macadamias have long been valued both for flavor and for nutrition.

The tree is equally impressive. An evergreen with tough leaves and elegant spring flowers, it matures into a productive, manageable canopy. Nuts develop slowly over six to seven months. Production begins in a few years and increases steadily as the tree matures. Plant it once, and it can reward you for decades.

Cold will come again. It always does. The question is not whether winter will test your garden. The question is whether your trees are ready. Macadamia proved it is. If you are building a garden that feeds you for decades, this is a tree worth planting.

😼😺 The Story Behind Smokey and Sunshine 🐾

 Grande  freeze  survival,  with  Sunshine  pointing  at  polar  bear  and  penguin 
 marketing  poster,  coffee  and  donuts  on  table,  tropical  plants  on  shelves  in 
 background.
Sunshine: You know, February 27 was International Polar Bear Day. I just learned about it and got a brilliant marketing idea. Cherry of the Rio Grande survived 25F. With wind. Real wind. That means we go north. Let them taste this magic. I even have a donut recipe with the fruit. It’s a bomb, Smokey. We expand. Trust me. Finally you can afford that new watering timer.

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 🍒❄️

Eugenia brasiliensis - Grumichama tree flowering and fruiting

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.
