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!

Fragrant Gold Leaf Orchid Vine

By Onika Amell, tropical plant specialist

Q: I am absolutely thrilled to see you have this vine. I've tried for years to get this plant! It is so, so rare. It just seemed impossible to find in this country. How do I make it thrive? I am ordering two.

A: We are happy to confirm that indeed we do have this rare vine!
Bauhinia aureifolia - Gold Leaf Orchid Vine - was discovered in Thailand in 1983. It is endemic to Pattani, Narathiwat, and Yala in Southern Thailand. Danish botanist Kai Larsen named this plant and hailed it as one of the rarest plant species of the world when it was discovered in the eighties.
The Thai people call this vine Bai Mai Si Thong. It is a beautiful climber with large, bi-loped leaves (7 inches or more!) and good branching.
Young leaves are a stunning burnt orange to terracotta color for about a week and as they reach full size, they turn green over a couple of days. This is a very rare color for Bauhinia. It produces leaves all the time and this means this vine is always full of beautiful color. With its golden leaves, it sure is reminiscent of Autumn.
This vine blooms from May to November. It bears bunches of small flowers that are delicately fragrant in the evenings. The cultivated plants range flower color from pure white to purple and pink, while the wild ones have often white petals with pinkish patches.
Bauhinia aureifolia needs well-drained soil, full light and good humidity to thrive. It will tolerate a light freeze once established and it is very important to protect young plants.
Gold Leaf Orchid Vine also makes a wonderful container plant with staking or support. It is a must for every rare plant collection!

Fun of growing your own Pepper

By Onika Amell, tropical plant specialist

Q: Can you grow your own black pepper plants in the USA?

A: Who does not love the smell of freshly ground pepper, especially that lovely combination of white, green, black and red peppercorns, which are so much more interesting than just plain black corns. Yes, you can absolutely grow your own pepper! Peppercorns come from the plant Piper nigrum.

Growing Pepper Plant

Black pepper plants are actually vigorous vines, although they are pretty slow growing and can be kept in a pot as a compact plant. But they will need a strong support to climb over. Indoors, you can provide this support by installing a trellis in a large pot. Some gardeners prefer to grow them as a hanging plant instead. In warm climates, you can plant them directly outdoors in a protected location with partial shade. These plants need rich, moist, well-draining soil and warm, humid conditions. Peppers do not like temperatures below sixty degrees, although they can survive some cold spells. It is very important to bring these plants indoors or wrap them in a blanket if colder weather arrives.
If you live in colder parts of the country, you can certainly grow peppercorns in large pots. Grow them outdoors during the summer and move them indoors during the winter, or grow them year-round in your greenhouse. Houseplants will need bright light and consistent moisture. Spray the leaves regularly with a bottle of water to increase humidity. Do not allow room temperatures to fall below sixty degrees.
Besides the benefit of being able to grow your own gourmet pepper corns, the foliage, as well as the flowers on this plant, are beautiful in its own right. Off-white flowers appear from spring through summer, followed by slow fruit production. The berries will appear on spikes, with 50 to 60 berries per spike.

Fertilize this vine in the spring before new vigorous growth emerges. We recommend:

You may be surprised to learn that black, white, green and red peppercorns are all the same seed on the same plant in the various stages of development and processing.

Black peppercorns are the most familiar and come from the corns that have reached their full size but are still green and not quite ripe. They are picked and allowed to dry in the sun. Enzymes in the berries cause the skin to turn black during the drying process. They are the strongest in flavor.

White peppercorns are the mature berries that ripen to a red color before being picked. After harvesting, they are soaked and rubbed free of the outer skin down to the smooth white underlayer, then dried and bleached by the sun. They are slightly milder than black pepper.

Green peppercorns are the unripe peppercorns picked at the same stage of ripeness as black peppercorns, but not allowed to dry. They can be pickled in vinegar or brine. They are the least pungent.

Red peppercorns are the mature, but unshelled version of the peppercorn. One can usually find them in some gourmet and health food stores. They can be quite expensive.

Ground pepper will only stay fresh for about three months, but peppercorns will last indefinitely. To make the most of your pepper harvest, store the peppercorns in an airtight container in a cool, dark location. Grind them immediately before use for the best flavor.
There is nothing like freshly ground black pepper simply combined with a good quality olive oil and a splash of balsamic vinegar. This makes a wonderful dipping sauce for fresh bread. Simple, yet elegant. All the better if the pepper was grown in your very own garden!

How to make leaves green?

Q: I purchased several plants from you and they all arrived in great shape. The Wrightia is very large and vigorous but some leaves are yellowish. How can I improve that look? Any special fertilizer?

A: Wrightias are very showy and beautiful plants, although sometimes they are susceptible to leaf chlorosis which in other words is iron deficiency, especially during wet rainy weather. It is not harmful to the plant and can be corrected with microelement applications. Use Microelements once a week to correct the iron deficiency that usually goes away within a month. Then maintain plants health with monthly applications. It is beneficial to use microelements in combination with regular applications of health boosting fertilizer.

Pink N Good Daily Plant Food - Flower Booster
Tropical Allure - Smart-Release Booster

How to grow Parijat indoors in winter

Q: I purchased Parijat plant last year spring. It had good growth in Summer, after that I kept the plant inside the house in winter. A couple of weeks it was ok, after that the plant lost leaves. What is a better idea for growing Parijat plant indoors in Winter?

A: Nyctanthes arbor-tristis, Parijat - is a semi-deciduous plant, which means, it may lose its leaves during unfavorable conditions such as drought, cold, low light and/or humidity. In your case, the plant dropped leaves because of the stress of moving indoors that includes reducing light and humidity levels. When a tropical plant loses leaves during winter, this means it goes into a dormant stage. If this happens, you need to reduce watering and keep the plant on a dry side, water in only when the top level of the soil feels dry to touch. Do not fertilize.
Try to place the plant in a well-lit spot such as a windowsill. If the windowsill and the window glass feel too cold for touch during wintertime, you may place a sheet of a Styrofoam underneath the pot, and a sheet of a bubble-wrap between the plant and the window glass, to create an extra barrier from cold. The plant may re-leaf during wintertime; if not, it may wait until spring, be patient.
Bring it back into outdoor light when minimum temperatures rise above 65F and resume fertilizing.
