Taking care of Soursop after shipping

Q: Since I have never grown a soursop tree before I need some pro help. My tree was delivered absolutely beautiful, leaves were a pretty green. I potted it and gave it a good drink of water and put it in a shaded area outside. Then the weather here became cool so I brought it in for a few days until the weather warmed, and it lost all the leaves. Is it in shock and will come around eventually? Will I be able to grow this tree indoors during winter?

A: Soursop - Annona muricata trees are very sensitive to temperature drops. This always causes leaf loss. You seem to be doing everything right. Do not water until soil gets slightly dry; keep it in bright shade. The weather should be good now with high temperatures and humidity rising. No fertilizer until the plant shows active new growth. Be patient with your plant, it should recover soon.

Soursop is an ultra-tropical tree and doesn't take any freeze. If you live in cooler climate, keep the plant in a pot (the good news is, Annonas in general have compact nature and are perfect for container culture). Bring the tree indoors during cold period, providing bright light.

We have very interesting article about growing and fruiting Soursop in apartment. Check out 4534 Tropical Treasures Magazine # 7.

Why Gardeners Are Secretly Obsessed With This Rare Brazilian Giant Walking Iris

Iris Regina - Neomarica caerulea

🔤 Why Gardeners Are Secretly Obsessed With This Rare Brazilian Giant Walking Iris



Meet Iris Regina - Neomarica caerulea: the rare, salt-tolerant Brazilian walking iris that blooms in under a year and thrives in shady, sandy soil where other tropicals fail.

One look at Iris Regina - and it's easy to see why tropical plant collectors quietly become obsessed with it. It pairs elegant, hand-painted blue-violet flowers with arching, sword-like leaves that instantly give your garden a lush, structural look.
But the real magic of this unusual Brazilian species isn't just its beauty - it's the fact that it thrives exactly where other tropicals fail.

The Plant That Thrives on Neglect (and Salt Air)



Originally discovered growing near the ocean in Brazil, Iris Regina naturally adapted to conditions that would frustrate most gardeners. Thriving in sandy soil, deep shade, and coastal salt spray, this plant is remarkably easygoing. While most flowering tropicals demand rich soil and perfect drainage, Iris Regina handles difficult planting zones with absolute grace.

👉 Quick Care Tip: While it loves moist, well-drained soil, overfeeding is a mistake. Too much fertilizer will give you massive leaves but fewer flowers!

Blooms in Less Than a Year



One of the most surprising traits of Iris Regina is how quickly it matures. Many rare ornamental plants test a gardener's patience for years before ever showing a bud. Fresh seedlings of this species, however, can reach blooming size in less than a year - an absolute rarity for a tropical perennial with such exotic flowers.

The blooms look like a cross between a rare orchid and a delicate iris. While individual flowers are short-lived, mature clumps continuously push out new blooms throughout the warm season, especially when kept evenly moist.

Light and Cold Tolerance: What You Need to Know



· Light: For the best foliage color and maximum blooming power, give it morning sun and afternoon shade. It can handle more sun, but only if you keep up with watering.
· Cold Hardiness: Iris Regina is comfortable down to about 30F. In warmer parts of Florida (Zones 9b-11), it performs beautifully outdoors year-round.
· Cold Climates: If you live in a freeze-prone zone, it makes an exceptional container plant. Just wheel it to safety when a freeze threatens.
Propagation: It's incredibly easy to divide, or you can grow it reliably fast from fresh seed.

25 Years of History: The Top Tropicals Connection



For us at Top Tropicals, Iris Regina isn't just another botanical listing - it carries a piece of our history. This specific variety was introduced by the legendary tropical plant collector Sid Gardino, who named it after his wife, Regina.

Sid and Regina have been longtime friends of Top Tropicals for over a quarter of a century. In fact, some of the very first plants in our nursery’s collection came from them more than 25 years ago. Plants like Iris Regina represent the early, passionate era of Florida plant collecting - treasures shared between friends long before rare plants became viral internet trends.

Today, Iris Regina still feels like a hidden gem compared to flashy orchids or massive aroids. But if you are looking for something elegant, salt-tolerant, and surprisingly easy to grow, this Brazilian walking iris might just become your favorite plant in the garden.

In Thailand, you will smell the Water Jasmine before you see it. Trace that soft, fruity, jasmine-like fragrance and you'll find Wrightia religiosa - an unassuming tropical shrub with tiny white flowers hanging like pendants. Also called Sacred Buddhist, this beloved plant is everywhere in Southeast Asia, cherished for its rich cultural history and old-world charm rather than loud colors.

💮 The Shrub of Buddhist Symbolism that Thai Temples Have Been Planting for Centuries

The species name religiosa is no accident. It literally refers to the plant’s long association with religious, spiritual, and cultural traditions across Thailand, Vietnam, Malaysia, and Singapore.

While the flowers themselves are visually simple, their unique growth habit has inspired generations of Buddhist symbolism. Unlike many flowers that point proudly toward the sky, the blooms of the Water Jasmine hang downward. In Thai culture, this downward-facing habit became a beautiful symbol of modesty and humility - a physical representation of bowing down rather than standing in pride.

Furthermore, many gardeners and monks associate the flower’s five distinct petals with foundational Buddhist virtues: wisdom, compassion, patience, kindness, and generosity. Whether ancient legend or folk interpretation, this cultural meaning has earned the plant a reputation as something sacred, making it a staple near homes and temple grounds.

💮 The Fragrance People Fall in Love With



Visually, Wrightia religiosa does not try to dazzle you with giant petals or wild, neon colors. Instead, its magic lies entirely in its scent.

The perfume it throws into the air is the real reason people become obsessed with it. It is a clean, intoxicating fragrance that drifts gracefully through the evening air. For anyone living in a warm climate, the best part is that the Water Jasmine is not a "one-and-done" bloomer. When the plant is happy, it flowers repeatedly and almost continuously throughout the year, meaning that incredible scent becomes a permanent fixture in your garden.

💮 From Temple Gardens to Bonsai Pots



Part of what makes Wrightia religiosa so widespread is its sheer versatility. It is an incredibly agreeable plant that adapts beautifully to whatever form a gardener desires. In Southeast Asia, you will see it styled as:
· A standalone specimen shrub
· A dense, fragrant privacy hedge
· A patio accent in containers
· A small, sculptural tree

It has also become an absolute classic in the tropical bonsai world. Because its branches are flexible, fast-growing, and highly responsive to pruning, even beginners can easily wire and shape young plants into twisted, artistic forms. Left to grow naturally, older plants develop a graceful, twiggy, and airy structure that looks naturally sculptural.

💮 The Fake-Dead Winter Quirk



Wrightia is easy to care for with standard sun and water, but it hates the cold (although survives it well). Below 65F, it abruptly drops all its leaves and looks completely dead. Many gardeners panic and throw it away - but it’s just resting. Simply bring container plants indoors for the winter. Once the warmth returns, it wakes up, flushes green, and resumes blooming.

💮 Subtle Beauty with Deep Roots



Some tropical plants impress with sheer size, but Wrightia religiosa does the opposite. Its beauty is quiet - thin branches, dangling white pendants, light green foliage, and a fragrance that gently fills a yard.

It is a plant with a few centuries of cultural history carried in its branches, and it is one of those rare garden gems you cannot truly appreciate until you experience its scent in person.

Randia formosa shrub in bloom with white star-shaped flowers, close-up of single bloom, and ripe yellow fruit with black pulp that looks like blackberry jam

Randia formosa - Blackberry Jam Fruit Tree with Flowers and Ripe Fruit

You know how some plants just surprise you?

That's Randia formosa - the Blackberry Jam Fruit Tree. At first, it just looks like a cute little gardenia-type shrub. Glossy leaves, sweet white flowers. Nice enough. But then the fruit shows up… and you crack one open and go, “Wait - this tastes like jam?!”

And not just any jam - like real, fresh blackberry jam. No sugar, no cooking. Just soft black pulp inside this golden little fruit. It's weirdly satisfying. One of those things you make everyone taste just to see their face.

What's even cooler is how easy it is. This thing starts blooming and fruiting when it's barely 2 feet tall. You can grow it in a pot on your porch, or even inside if it gets enough light. And while most of your other plants take the winter off, this one keeps going - flowers, fruit, the whole show.

If you've got a spot with filtered light and a little curiosity, it's absolutely worth a try. Honestly, it's just… fun.

This rare South American evergreen shrub checks all the boxes: fragrant, compact, easy, and edible.

✅ Grows in pots ✅ Indoors ✅ Small yards

Randia formosa – Blackberry Jam Fruit Tree – FAQ

What is Randia formosa?

Randia formosa, also known as Blackberry Jam Fruit or Jasmin de Rosa, is a compact tropical shrub that produces fragrant white flowers and small yellow fruits filled with soft, black pulp that tastes remarkably like blackberry jam. It belongs to the Rubiaceae family, the same as Gardenia and Coffea.

Why gardeners love Randia

  • Delicious jam-flavored fruit – no sugar needed.
  • Compact grower – perfect for patios and indoor spaces.
  • Fast results – blooms and fruits within 1–1.5 years.
  • Big yield in a small pot – 25–30 fruits at once!
  • Fall–Winter performer – keeps going when others stop.
  • Kid favorite – fun to grow, fun to eat.

What does the fruit taste like?

The pulp inside the fruit tastes just like fresh blackberry jam - sweet, tangy, and rich. It is edible fresh, without any processing or sweeteners, and is loved by both kids and adults.

How big does the plant get?

In the ground, Randia formosa typically reaches 4 to 5 feet tall. In containers, it usually stays smaller, around 3 to 4 feet, making it perfect for small gardens, patios, or indoor growing.

How soon will it fruit?

Very quickly! This is one of the fastest fruiting tropicals. Plants begin to flower and produce fruit within two years from seed. Еstablished plants in 3 gallon containers may begin fruiting at just 2 feet tall.

Does it need full sun?

No. It actually prefers filtered light or partial shade, especially in hot climates. Leaves tend to look healthier and greener when grown in dappled light.

Can I grow Randia formosa indoors?

Yes! Its compact size and shade tolerance make it an excellent choice for bright indoor spaces. Just be sure to provide good air circulation, high humidity if possible, and avoid cold drafts.

How cold-hardy is it?

Mature plants can tolerate temperatures down to about 26F for short period of time, but young plants are more sensitive and should be protected from frost. It is best grown outdoors in USDA zones 9b and up or kept as a container plant that can be brought indoors in winter.

What kind of soil does it need?

Randia formosa requires acidic, well-draining soil. Avoid alkaline soils, which may cause leaf chlorosis (yellowing with green veins).

How often should I water it?

Keep soil evenly moist but not soggy. It is sensitive to overwatering, especially in cooler weather. During winter, reduce watering. Underwatering may cause sudden leaf drop - but the plant usually recovers quickly once watered again.

What fertilizer does it need?

Yes. Use a slow-release fertilizer formulated for acid-loving plants. Regular applications of micronutrients (especially iron and magnesium) help prevent chlorosis. Foliar sprays can also be helpful. Apply Sunshine C-Cibus Booster or Green Magic controlled release fertilizer to keep your plant happy: Blackberry Jam Fruit is a heavy feeder!

When does it flower and fruit?

This plant can bloom and fruit for several months, often from summer through winter. It is known to bloom off-season, making it a fun and productive plant when others are dormant.

Are the flowers fragrant?

Yes, the white star-shaped tubular flowers have a light, sweet fragrance, similar to gardenias but less intense. The flowers open at night.

Is it self-pollinating?

Yes. A single plant can set fruit on its own, although insect activity can improve fruit set.

Are there any common problems?

The most common issue is chlorosis, which shows up as yellowing leaves with green veins - usually due to overwatering, poor drainage, or alkaline soil. It's fixable with acidification and micronutrients. The plant may also drop leaves suddenly if underwatered but tends to bounce back.

Is this plant related to Gardenia?

Yes. It is in the same plant family (Rubiaceae) as Gardenia and Coffee. That's why the flowers look similar and why it tolerates similar care needs.

Can it be used for bonsai or miniature tree styling?

Yes, due to its slow growth and branching habit, Randia formosa can be shaped into a miniature tree form and is quite attractive when trained.

Is it drought-tolerant?

Once established, it shows moderate drought tolerance. However, young plants need regular watering and are more vulnerable to drying out.
