Hardy Plumeria Pudica

Q: I have ordered plumeria pudica from you in March and it is thriving really well here in Rancho Cordova, California. The current temperatures are ranging from 68 to 32 degrees Fahrenheit. My USDA zone is 9b. Does this plumeria pudica survive outside with temperatures dropping in coming winter in CA?

A: From our experience, Plumeria pudica is pretty cold hardy and takes some cold spells in spite of being a tropical species.
Our trees (well-established) took a few hours of freeze with no significant damage.
Potted plants are less hardy than in-ground plants. However, their advantage is, they are easy to move indoors or inside warmer place like garage, etc. If the temperature stays borderline around 32F for a few hours, the plant should be safe as long as warm day temperatures follow a cold night. For longer periods of cold, move the plant inside.
Make sure do not overwater and keep Plumeria on a dry side during winter, since cold and wet is a bad combination and may cause root problems.
Above is the picture of Plumeria pudica tree growing in Cape Coral, FL where low temperatures in winter sometimes go down to upper 20's for a few hours.

To improve cold hardiness of Plumerias and other tropical plants, use SUNSHINE-Epi-T for plant thermal protection and immune system boost.
Make sure to fertilize plants on regular basis to keep them strong and vigorous. The stronger and bigger the plant, the hardier it is!

RECOMMENDED FERTILIZERS:
Plumeria Top Dress - Smart-Release Booster
Pink N Good Daily Plant Food - Flower Booster
Tropical Allure - Smart-Release Booster

What to do and not to do before a cold snap?



Growing tropical plants outdoors? Here are a few practical notes for your cold protection guide.

⭕️ 5 things to DO to prepare your plants before a cold snap:



1. Water well. A well-hydrated plant is stronger. Juicy stems and leaves handle cold better than dry ones.
2. Add mulch. A thick layer around the base helps insulate the roots and keep them warm.
3. Block the wind. Move pots to a sheltered spot or set up a windbreak.
4. Cover at night, uncover by day. Use frost cloth, blankets, or plastic at night - but remove during the day so plants don’t overheat in the sun and can get as much light as possible.
5. Add gentle heat if needed. Christmas lights or a small heater can help - just use caution and make sure everything is safe.

❌ 5 most common mistakes, what NOT to do before or during a cold snap:



1. Don’t prune. Fresh cuts and new growth are tender and will freeze first.

2. Don’t overwater. Cold and soggy roots can rot. Keep soil moist, not soaked. Water just enough to quench the plant’s thirst and fill stems and leaves with moisture. Cold and wet is a dangerous combination.

3. Don’t let plants dry out either. Wilted, thirsty plants are more likely to suffer cold damage. Cold and dry can be just as harmful as cold and wet.

4. Don’t use dry fertilizer. It can burn roots in cold soil. A gentle liquid feed like amino-acid Sunshine Boosters is an exception and safe to use with every watering. Its intake naturally slows down as watering decreases.

5. Don’t just watch the thermometer. Duration and wind chill matter. A long cold night with wind can do more harm than a brief freeze.

✔️ Keep these in mind, and your plants will thank you when the cold passes!

♊ Gemini Season Starts. We Are Five Days Late. Very Gemini.

Smokey  and  Sunshine  with  Gemini  tropical  plants  in  a  whimsical 
 greenhouse
Sunshine: I once met a girl and asked what she does. She said she assembles gyroscopes. I told her I don't believe in gyroscopes.
Smokey: You meant horoscopes.
Sunshine: That is what I said.
Smokey: You said gyroscopes.
Sunshine: Same thing.
Smokey: One predicts your future. The other stabilizes aircraft.
Sunshine: I don't believe in aircraft either.
Smokey: She left, didn't she.
Sunshine: She said she had to go assemble something.

♊ Gemini season started on May 21. Today is May 26 But honestly? That is not a problem. That is actually very Gemini. Gemini probably got distracted, opened three browser tabs, started a new hobby, forgot what it was doing, and came back five days later with a notebook full of ideas and zero apologies. So here we are.

Why these plants and not others

No, there is no scientific proof that olive trees belong to Gemini. We checked. The olives refused to comment. But if you are going to assign plants to zodiac signs — and we are — then Gemini deserves plants with intelligence, motion, surprise, fragrance, and a little chaos. Gemini is the sign of curiosity, conversation, and dual natures. It gets bored easily and talks to everyone at the party. These plants were picked because they fit that energy. And also because they are genuinely good plants worth growing, which Smokey insisted we mention.

Olive (Olea europaea)

Close-up  of  an  olive  tree  branch  laden  with  clusters  of  green  olives 
 among  narrow  silvery-green  leaves.  The  fruit  is  ripening  on  the  tree  and 
 hanging  from  slender 
 stems.

Clusters of green olives developing on an olive tree branch. Olive trees are evergreen, drought-tolerant, and have been cultivated for thousands of years for both their fruit and the oil produced from it.

Olive is the thinking plant of this group. Ancient, silver-leaved, and quietly dramatic, it belongs to Gemini because Gemini loves history, long conversations, and plants that look like they know something you don't.

If you are growing olive in a container — which works very well — give it full sun, fast-draining soil, and a firm commitment to not overwatering it. Olive does not want wet feet. It wants to think in dry conditions, like a philosopher in a warm courtyard.

Smokey: Olive represents thousands of years of cultivation and human civilization.
Sunshine: And snacks with much better branding than they get credit for.

Dwarf Mulberry (Morus sp.)

Branch  of  a  Dwarf  Everbearing  Mulberry  tree  displaying  fruit  in  various
    stages  of  ripening,  from  pale  green  and  pink  to  deep  purple-black,  against 
 a  bright  blue 
 sky.

Dwarf Everbearing Mulberry produces fruit over an extended season, often carrying berries in multiple stages of ripeness at the same time. The sweet, blackberry-like fruit is a favorite of both gardeners and wildlife.

Mulberry is Gemini in motion. It grows fast, produces generously, and absolutely refuses to be boring. A standard mulberry will take over your yard before you finish reading this sentence. A dwarf mulberry, however, is patio-friendly, container-happy, and still delivers fruit, birds, and mild garden chaos on schedule.

Prune after fruiting to keep the shape. Full sun. Large pot if you're growing in a container. This is the plant for people who want results and do not enjoy waiting.

Smokey: Efficient growth rate. Edible output. Compact habit. Reasonable choice.
Sunshine: Finally, a tree with a snack schedule.

Parijat (Nyctanthes arbor-tristis)

Close-up  of  Parijat  flowers  (Nyctanthes  arbor-tristis)  with  white 
 pinwheel-shaped  petals  and  bright  orange  centers  surrounded  by  fresh  green 
 leaves  and  unopened  flower 
 buds.

Parijat, also known as Night-Flowering Jasmine, produces fragrant white flowers with vivid orange centers that open at night and often carpet the ground beneath the tree by morning.

Parijat belongs to Gemini's quieter, more poetic side. It blooms with small fragrant white flowers — orange centers, delicate petals — often at night. By morning, the flowers have fallen. They drop like little messages from the universe, which Sunshine finds meaningful and Smokey finds botanically interesting.

This one is for the gardener who wants something to actually stop and look at. Good in containers, good on a warm patio, needs decent light and warmth to do its best work.

Smokey: Night-blooming pattern. Fragrant ornamental. Grows well in warm climates.
Sunshine: It's a tree that leaves notes.

Dwarf Golden Tabebuia (Tabebuia chrysotricha)

Dwarf  Golden  Tabebuia  tree  covered  in  bright  golden-yellow  flowers, 
 standing  in  a  lawn  beneath  a  blue  sky,  with  a  carpet  of  fallen  blossoms 
 surrounding  the 
 trunk.

Dwarf Golden Tabebuia puts on one of the most spectacular spring displays, covering its branches with brilliant golden flowers before the leaves emerge. The fallen blooms create a striking yellow carpet beneath the tree.

This is the Gemini show-off. Quiet for most of the year, then suddenly covered in golden yellow flowers like it just remembered it has an announcement to make.

Dwarf Golden Tabebuia is compact enough for a large container or a sunny entrance, but it needs strong light to bloom well. Give it sun. Give it room. Then step back and let it perform.

Smokey: Seasonal flowering response triggered by environmental conditions.
Sunshine: Botanical applause.

Miracle Fruit (Synsepalum dulcificum)

Clusters  of  bright  red  Miracle  Fruit  berries  growing  among  glossy  green
    leaves  on  a  compact  shrub.  The  elongated  fruits  stand  out  against  the  lush 
 foliage.

Miracle Fruit is famous for its unique berries, which contain miraculin - a natural compound that temporarily makes sour foods taste sweet. The attractive evergreen shrub produces bright red fruit and is well suited to containers and small gardens.

Miracle Fruit belongs on this list because it is, without argument, the most Gemini plant in existence. It does not taste like much on its own. But eat one berry and everything sour suddenly tastes sweet. Lemons taste like lemonade. Lime juice tastes like candy. A plain piece of sourdough becomes something you would pay extra for. The fruit literally changes how you experience everything that comes after it.

If that is not Gemini energy — dual nature, transformation, making you see the same thing two completely different ways — nothing is.

Miracle Fruit is a slow grower that likes warmth, humidity, acidic soil, and protection from cold. It does well in containers, which is good news because it genuinely hates frost. Keep it in a pot, bring it in when temperatures drop, and give it filtered light or morning sun rather than harsh afternoon exposure.

Smokey: The active compound is miraculin. It binds to taste receptors and distorts sour perception at low pH. Temporary effect, roughly thirty minutes to an hour.
Sunshine: It's a fruit that lies. Beautifully.

Spanish Tamarind (Wild Medlar, Vangueria infausta)

Spanish  Tamarind  (Vangueria  infausta)  tree  with  glossy  green  leaves  and
    clusters  of  round  fruit  in  various  stages  of  ripening,  from  green  to 
 golden-brown,  growing  on  branching  stems  in  a  lush  tropical  garden  setting.

Spanish Tamarind (Vangueria infausta) may be grown for its unusual fruit, but it also brings beauty to the garden with its lush foliage and heavy crops of ripening fruit. Green and golden-brown fruits often appear together on the tree, creating a colorful display.

Spanish Tamarind belongs to Gemini because it is unusual enough to start a conversation before anyone even knows what it is. The name alone does it. People will ask. You will explain. The fruit changes color as it ripens, the plant has collector appeal, and the whole thing feels like something you found in a book about plants that don't get enough attention.

This one needs warmth, sun, good drainage, and patience. It can live in a container with pruning. It rewards the gardener who is genuinely interested in something a little different.

Smokey: Tropical fruiting curiosity. Suitable for collectors.
Sunshine: Sounds like something I would order at a restaurant without reading the description.

One of the traditional uses of Spanish Tamarind (Vangueria infausta) is fruit tea. The ripe fruit can be dried and steeped to make a mild, refreshing drink rich in natural flavor, while the soft, velvety leaves have long been used in traditional herbal infusions.

Horoscope aside — why these plants are actually worth growing

Even if Gemini energy has nothing to do with your garden, these plants offer real value: fruit, fragrance, flowers, container growing, and something interesting to look at or talk about.

  • Olive — full sun, excellent drainage, don't overwater, thrives in containers. Tropical varieties: USDA Zone: 8-10. Cold hardy to 15-20°F.
  • Dwarf Mulberry — full sun, large pot, prune after fruiting, fast results. USDA Zone: 8-11. Cold hardy to 20-25°F. Most mulberry varieties can be grown in USDA Zone 5-6 to 10 and cold hardy to 5°F.
  • Parijat — warmth, good light, patio or container, fragrant and ornamental. USDA Zone 9-11. Tolerates light freezing to about 30°F for short periods (mature plants). Young plants must be protected.
  • Dwarf Golden Tabebuia — strong sun, large container or sunny ground spot, compact but dramatic when it blooms. USDA Zone 9-11. Protect young plants from frost. Best flowering in full sun.
  • Spanish Tamarind — warmth, sun, drainage, patience, collector interest. USDA Zone 9-11. USDA Zone 10-11, possibly warm Zone 9b in protected microclimates. Protect from frost, especially young plants.
  • Miracle Fruit — warmth, humidity, acidic soil, filtered light, protect from frost. Best in containers. USDA Zone 10-11. Cold hardy only to about 40°F — bring it in well before first frost, not after.

Can you grow them in pots?

Yes. With the standard warning: a pot is not magic. Use a large container, fast-draining soil, full sun where the plant wants it, regular feeding with Green Magic conrolled-release fertilizer every 6 months and Sunshine Boosters - safe to use with every watering. Apply a bit of pruning when things get out of hand.

Smokey: A pot is just a smaller universe.
Sunshine: A pot is a drainage system with ambitions.

📅June gardening reality check

June is a good time to establish tropical and subtropical plants. The soil is warm, the days are long, and actively growing plants will take root faster than they would in cooler months.

👉 A few things to keep in mind:

  • Containers dry out fast even when rain increases. Check them. Don't assume rain did the job.
  • Don't let pots sit in standing water. Root rot is quiet until it isn't.
  • Feed actively growing plants. They are working hard and they need the input. We recommend Green Magic controlled release fertilizer during active growth (twice a year) and Sunshine Boosters for spray and daily watering year around.

    📚 More about fertilizers from our garden Blog

  • Watch new growth for pests. Tender leaves are the first target.
  • Prune lightly to shape if needed, but don't do heavy cutting in peak heat. Save that for after flowering or early in the season.
  • Mulch around in-ground plants to hold moisture, but keep mulch away from the trunk.

🌠 The stars don't care? Grow anyway!

Maybe the stars do not care whether your garden is a Gemini garden. Maybe olive trees are not receiving transmissions from Mercury. But a garden full of fruit, fragrance, flowers, and strange little stories is still a very good idea.

Smokey: That is the first reasonable conclusion in this entire article.
Sunshine: Second. The donut research was also important.

Happy Gemini gardening season from all of us!

Cold hardy tropical fruit trees for Luisiana

Q: I've just moved to Louisiana and have been wondering whether it would make sense to plant some tropical fruit trees in our garden. Average lows in New Orleans are 41 deg F in January and February, although we did hit 25 once with the Arctic vortex. I'm interested in litchi, longan, rambutans, and persimmons. Do you have varieties that can tolerate Louisiana's temperature range? I'd love mangosteen but I don't suppose they will survive. Do you have any suggestions on tropical fruit trees that I could try?

A: Average temperatures are for statistics only; it is actual temperatures that may hurt your cold sensitive plant. This is what you should keep in mind when starting your tropical fruit collection:
1) Ultra-tropical plants like Rambutan can not survive winters below 45-50F. However, they can be successfully grown in containers in a greenhouse or moved indoors into a sun room during cold periods.
2) Tropical plants like Litchi and Longan may take some light frost once established. Still, for areas with freeze our advice is - keep them in pots and move inside in case of cold.
3) There is a number of subtropical fruit trees that are hardy enough to take some freeze. Persimmon, Feijoa, Fig, Cattley Guava, Jujube, Kiwi, some Eugenias and others. Please refer to our Tropical Fruit Sensitivity Chart.
4) Remember that plant's ability to survive winter depends on several factors, not only temperature itself. Important factors are: wind protection (chill wind kills rather than low temperature itself), exposure, how close the tree is planted to the house, plant maturity and its overall strength and health. If a plant had received good nutrients during summer, has well established root system, planted in enclosed area protected from winds and has plenty of bright sunlight - it has better chances to survive than a weak plant in warmer conditions.
5) Use SUNSHINE plant boosters for improving cold tolerance of your tropical plant. It only takes a few drops, and only costs $5!
