As I was headed into my local nursery the other day, an interior-plant deliveryman was unloading a van out front. Because I am perennially curious and a devout plant lover, I poked my head inside and saw the vehicle was basically a fully loaded plant-candy store with a fine selection of leaves and stems instead of chocolate and sprinkles. And because I am that kind of person, I struck up a conversation with the grower. After taking the one-minute “tour” of the truck, I asked him what his most popular plant was. You guessed it: ZZ plant (Zamioculcas zamiifolia).
ZZ plant is the quiet hero of nearly any Instagram-worthy houseplant collection, the stalwart soldier in the corner of the photo frame as you scroll through thousands of s of #houseplantsofinstagram and #crazyplantlady foliage.
Turns out there’s a good reason that tropical plant Z. zamiifolia is a social media darling. After further discussion (and not even trying to pronounce the lengthy name), I was so convinced that I marched into the nursery and bought my own #zzplant. What persuaded me?
Barletta flowers are beautiful tropical plants that can be grown as houseplants. Their life cycle goes through several distinct stages as they grow from a seed to a mature flowering plant. In this article, we’ll explore the different phases of Barletta floral development so you can better care for these gorgeous blooms.
Seed Germination
It all starts with a seed. Barletta seeds have a hard outer coating that needs to be softened before germination can occur. This scarification of the seed coat can happen naturally outdoor in the soil over time. But for faster indoor germination, you can soak the seeds in warm water overnight.
Once the seed coat has been softened, the seeds can be planted in a light, fertile potting mix. Barletta seeds require warmth and moisture to sprout. Keep the soil moist and provide a temperature of at least 70°F. In optimal conditions, the seeds should begin to germinate in 7-14 days.
Seedlings emerge from the soil and immediately begin the next stage of growth. Handle new seedlings carefully since they are fragile at this point Also provide plenty of light from this early stage onward to prevent leggy, weak growth
Seedling Establishment
For the next few weeks after sprouting, Barletta seedlings work on developing their root system and leaves. Two embryonic seed leaves (cotyledons) initially emerge. These oval-shaped leaves supply the young plant with energy until the first true foliage leaves form.
Once the cotyledons fully expand, the first set of true leaves will start growing. These early true leaves look like miniature versions of mature Barletta foliage All the leaves at this point have smooth, entire margins
During seedling establishment, let the surface slightly dry out between waterings but don’t let the soil get overly dry. Place the seedlings in the brightest spot you have without direct hot sun. Adequate light keeps the foliage from stretching and becoming floppy.
Juvenile Vegetative Growth
After a few months of growth, Barletta plants transition into the extended juvenile phase. The plants will focus on vegetative development, increasing in size and branching out. But flowers won’t bloom at this stage even under ideal conditions.
The leaves progressively get larger and more lobed. You’ll notice leaves emerging with 3, 5, 7 or more lobes. But even the most divided juvenile leaves won’t have the finely dissected, lacy look of mature foliage. Leaf margins will also lack any ruffling or crinkling at first.
Your Barletta can stay in the juvenile growth phase for 1-3 years. Ensure the plant receives at least 4 hours of direct sun daily for robust growth at this stage. Also provide ample water and nutrients, especially during the active growth period in spring and summer.
Mature Vegetative Growth
Eventually your Barletta will transition from juvenile to mature vegetative growth. The plant’s energy switches from leaf production to flowering as it enters the blooming stage. But even before the first flower buds appear, you can recognize mature growth by the foliage changes.
Mature Barletta leaves get extremely divided and finely cut, taking on the classic laceleaf look. The leaf margins also develop ruffled crinkles and waves when the plant is happy. Mature foliage provides the backdrop to showcase the forthcoming flowers.
At this point, your Barletta has likely become a large, bushy plant. You can prune or trim the plant as needed to control size and shape. Just avoid removing too many leaves right before the flowering period. Continue providing optimal care with sunlight, water, humidity and nutrients.
Flower Bud Formation
Under the right conditions, mature Barlettas will begin to form flower buds. The buds emerge at the branch tips, nestled between the upper leaves.
Barletta flower buds are oval in shape and light green, gradually darkening as they mature. They grow on short, weak stems so take care not to damage the buds when handling the foliage. Don’t be surprised if some of the first buds abort and fall off before blooming. This is completely normal.
Make sure to continue optimal care through this critical stage. Insufficient sunlight, low humidity or overwatering during bud formation can prevent flowering. But once flower buds successfully form, get ready for a spectacular floral display!
Pollination and Fertilization
After 4-8 weeks of bud development, Barletta flowers finally begin to open. Each mature bud produces an intricate bloom up to 8 inches wide.
The coloring ranges from pure white to various pastel shades of pink, purple and peach. Inside the flower, pollen-producing anthers top the stamen while the stigma is receptive to pollen.
For indoor Barlettas, you’ll need to manually pollinate the flowers by transferring pollen from the anthers to the stigmas using a small brush. Outdoors, natural wind and/or insects take care of pollination. Successful pollination leads to fertilization and seed production.
Seed Pod Formation and Ripening
In the weeks following fertilization, the ovaries at the base of the flowers begin to swell as seed pods develop. The flower petals fade and dry out, revealing the growing pods.
Immature Barletta pods are soft and green. As the seeds mature, the pods turn brown and become woody. You’ll know the pods are ripe when they make a rattling sound when shaken. The pods split open when completely dry, releasing dozens of seeds.
You can harvest the pods once they turn brown if you wish to collect seeds. Leave pods on the plant longer for fully ripe seeds. Careful hand pollination and successful seed pod formation complete the Barletta life cycle.
Caring for Barlettas Through Their Growth Stages
Now that you know what to expect as your Barletta progresses through its life cycle, here are some general care tips for each stage of development:
-
Germinating seeds: Provide warmth and consistent moisture.
-
Seedlings: Allow soil to slightly dry before watering again and supply plenty of light.
-
Juvenile plants: Give at least 4 hours of sunlight, water when top inch of soil dries, and feed every 2-4 weeks during growing season.
-
Mature plants: Prune to control size/shape, keep humidity above 50%, and avoid overwatering.
-
Flowering plants: Don’t prune excessively right before buds form. Ensure optimal sunlight, water, humidity and nutrients for best flowering.
-
Seed production: Hand pollinate flowers for pod formation. Harvest pods when brown or leave to fully dry on plant.
Following the proper care guidelines tailored to the stage of growth will help ensure your Barletta thrives. These stunning tropicals will reward your efforts with unmatched lacy foliage and showstopping blooms year after year. Enjoy watching your Barletta transform through its unique life cycle!
What is a ZZ plant?
Zamioculcas zamiifolia has been around for centuries, originating in drought-prone Africa (where it thrives outdoors). A couple of decades ago, Dutch nurseries located in South Africa saw the plant’s propagating potential and in 1996 started distributing it around the world. Since then, ZZ plants have entered hearts, homes, and offices worldwide.
Why are ZZ plants so popular?
Above: A four-inch ZZ Plant comes in a plastic nursery pot; $11 from The Sill. ZZ plant, with its wide, attractive, dark green leaves, boasts many favorable traits for offices and homes. ZZ plant tolerates neglect, is drought tolerant, and accepts low-light conditions without throwing a fit. Its waxy, smooth leaves reflect sunlight and brighten rooms. ZZ usually grows slowly to a height and width of two to three feet so it is not a plant monster that outgrows containers quickly.
ZZ plant also is an air purifier and in a NASA study, researchers found it is specifically adept at removing copious amounts of toxins such as xylene, toluene, and benzene from the air.
