❄️ 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.

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

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.

A Miracle for every special garden:
Synsepalum - Miracle Fruit

Miracle  Fruit,  Large  Leaf  variety,  Synsepalum  subcordatum

...Every tropical plant lover wants to have this plant in their collection. And there are at least three good reasons for it:
1) it is a true miracle fruit
2) It enjoys growing in a pot, stays compact and brings you miracle berries nearly year around
3) it can be grown indoors as it has very low water and light needs.

Miracle fruit is one of the strangest tropical fruits. The most unusual thing about it is the effect it has on one's taste after this miraculous berry has been consumed. The "miracle" is that if lemon or other sour food is eaten after the miracle fruit, the sour tastes sweet, as if sugar has been added. That kind of magical experience is unforgettable! The interest in this plant is so high that anyone who has a plant always finds eager volunteers to test its sweetening properties. A natural chemical in the fruit masks the tongue's sour taste buds so that lemons taste like lemonade or lemon pie, or lemon candy; beer tastes like Malta drink, sour strawberries taste super sweet, and a grapfruit tastes delicions and not bitter! What causes the miracle? The fruit has a unique taste changing glycoprotein that inhibits tastebuds' perception of sour taste. The sweet sensation lasts for half an hour to a few hours...

How to grow a nice Olive tree fast?

by Ed Jones, the Booster guy

Q: I got an Olive tree from you a few months ago, planted in the ground and it is doing well, but I don't see any active growth. The tree looks healthy but still about the same size when I planted it in June. I'm old and I want to see the olives sooner than later. Any suggestions, should I give it some fertilizer?

A: Olive trees are relatively slow growers, however, with balanced nutrition they can grow much faster, as fast as a few feet per year. Check out this Article by Ed Jones where he describes how he grew nice, bushy Olive trees just within one season with a help of Sunshine Boosters fertilizers. The article shows in details how to properly use liquid fertilizer on your fruit trees.

Small flowering tree for community

Q: Hi, I live on the east coast near West Palm, but I see you ship your plants. My HOA allows for Yellow Tabebuia species and I'm looking for two or three smaller trees that can fit in my front yard in smaller spaces. Ideally looking for trees that would stay under 20' in height, but preferably even smaller. Can you tell me the average height and spread of the Dwarf Golden Tabebuia or Silver Trumpet trees?

A: The Yellow Tabebuia - Tabebuia caraiba is a very good choice for a small yard. It grows about 20 ft average size, 7-10 ft wide. Sometimes taller, but it is slow growing and it will take many-many years to grow to a bigger size. It is a spectacular tree when in bloom, however, keep in mind that it is not very wind resistant; although it is not difficult to secure it back being a small tree. Another Tabebuia which is even more compact tree, has stronger root system and is more wind resistant:
Tabebuia chrysotricha - Dwarf Golden Tabebuia
Also some other interesting choices:
Radermachera Kunming - Dwarf Tree Jasmine
Senna polyphylla - Bahamas Cassia, Desert Cassia
Cordia sebestena - Scarlet Geiger tree
