Dwarf and Condo mangoes - easy mangoes

Q: We leave in zone 6a, could you tell us what is the list of different types of mango plants that could be planted indoor and that they can bear fruits?

A:There is a large group of mangoes called "Condo Mango" - they literally can be grown in your apartment! Those are dwarf varieties that can remain compact in containers with minimal pruning and successfully bear fruit providing bright light and proper care, including plant food.

The best dwarf and semi-dwarf varieties are: Carrie, Cogshall, Cushman, Fairchild, Graham, Ice Cream, Julie, Mallika, Nam Doc Mai, Pickering, Irwin, Jahangir, Juliette, Lancetilla, Little Gem, Manilita, Sia Tong, Torbert, Pim Seng Mun, Super Julie.

They produce juicy, fiberless sweet fruit. Julie is also a very popular dwarf variety, however, it is very cold sensitive and not the easiest to grow. If you get a 3 gal size mango, step it up to 7 gal when the plant reaches 4 ft; you may use a bigger container as the root system grows, up to 15 gal or even 25 gal, space permitting. Trim the tree under 6-8 ft after production season is over (summer-fall).

Super RARE: the Honduran Moon-Torch Cactus

by Mark Hooten, the Garden Doc

The most wonderful, easily growing, giant flowering, fragrant, and floriferous species of Selenicereus I have grown is an almost unknown species called Selenicerius hondurensis. While its climbing stems are rarely thicker than a Sharpie marker, it's flowers measure 12 to 14 inches across (!), open as the sun is setting, and produce a most incredible fragrance... very rich and spreading thru the area. It smells like a combination of both white chocolate and vanilla. S. hondurensis also develops the most richly colored flowers of the Selenicerei, the outermost petals being a glowing orangey-gold. It's very stunning and provocative! It flowers magnificently, several times during the summer... Continue reading...

Variegated Shell Ginger - Alpinia zerumbet

By Onika Amell, tropical plant specialist

Q: I live in Deltona, Florida and hoping to find spreading ginger with interesting foliage to grow in a partially shaded area in my garden under a group of trees. Any suggestions?

A: Variegated ginger Alpinia zerumbet variegata is a clumping ginger valued for its beautiful variegated foliage. The dark, green leaves have striking yellow stripes. This ginger is sought-after, not only for the stunning foliage but also for its beautiful flowers. The flowers are different from other members of the ginger family and appear in drooping racemes from the ends of leafy stems rather than directly from the rhizomes. This ginger is also commonly known as Shell Ginger because the flowers resemble seashells! They are pink-tinged, fragrant and appear in summer. This evergreen perennial grows in upright clumps 3-5 feet tall. You may prune the plant to control size.
It does not tolerate drought or a hard freeze but can take a few hours or light frost (goes dormant in such case). In colder areas, rhizomes should be dug up and stored in a cool room during winter.
This ginger will love a shaded corner in your garden. Plant it in organically rich, well-drained soil in full sun to part shade. Keep the soil moist but not soggy, and spread a thick layer of organic mulch around the plant for moisture retention. There are no serious insect or disease problems to worry about!
This ginger can be also be grown as a house plant as long as it has bright light and humid conditions. It will grow to around 3-4 feet tall as a houseplant.

True love of Night Blooming Jasmine

By Onika Amell, tropical plant specialist

Q: I live in New Cumberland, West Virginia. I love the smell of Night-Blooming jasmine. Is it possible to grow it in the northern panhandle of West Virginia? Do I have to plant it every year or do I keep it in a pot and take it inside during the winter months?

A: Technically, Night Blooming Jasmine is not a true jasmine (those plants belong to Oleaceae, or Olive family). Night Blooming Jasmine belongs to the Solanaceae family, also known as the Nightshade or "Potato" family of plants. Yes, this sweet fragrant flower called Jasmine for its perfume is related to potatoes and tomatoes!
Night Blooming Jasmine - Cestrum nocturnum - is loved by many gardeners for its beautiful fragrance at night. It is one of the most fragrant tropical evergreen shrubs available. Cascading clusters of tiny, tubular pale yellow to white flowers open at night and release a heavenly fragrance throughout the garden, especially on warm summer evenings. The fragrance is much lighter during the day. Night Blooming Jasmine is grown year-round in zones 9-11. It is at its happiest in a sunny to a partially sunny spot in your garden in well-drained soil but can be grown in cooler climates as a container or greenhouse plant.
You would absolutely be able to enjoy this plant during the warm months in West Virginia, but it will most certainly not survive outside during the winter. You will have to bring it inside. Take it outside again only once you are confident there is no more possibility of frost. When grown indoors, be sure to give it the sunniest, South facing window in your home. When grown in a container, you will need to re-pot it every two to three years so it doesn't become root-bound.
For those who are lucky to live in frost-free areas, in ideal growing conditions outside, it can easily reach 8 feet with a spread of 5 feet. It has a lovely informal look that can soften a more manicured garden. Add organic matter to the planting hole when you plant to enrich the soil around the root ball. Water well in the summer, but allow them to dry out a bit between watering in the winter. Plant this Jasmine near pools, porches, doors, windows, and walkways where its lovely fragrance can be enjoyed. The shrub is also an excellent plant for privacy hedges and screens. When grown as a hedge, plant 3 feet apart.
Trim lightly after a bloom cycle to shape and then do a hard pruning in fall or spring to control the size of this plant. Fertilize 3 times a year - in spring, summer, and autumn - with a good quality granular fertilizer.

Interesting facts:

Night-blooming jasmine is an excellent mosquito repellent. The powerful scent of the flowers attracts moths and bats that feed on mosquitoes and other small insects.
The flowers of the Night Blooming jasmine are widely used in India and other countries of South Asia for perfumery, medicinal applications and in religious ceremonies.

How soon will Guava tree fruit?

Q: Can you tell me how your Guava trees are propagated? Grown from seed vs. air grafted, etc.? I'm interested especially in the Barbie variety. In particular, I'd like to know how long it takes them to bear fruit - I live in Southern California zone 10b, with good sunlight.

A: Guavas can be propagated by seed, air layers, or grafting. Propagation method depends on the species.
Cattley guavas - Psidium littorale - are usually grown from seeds and start flowering and producing as early as in 2-3 years from seed. Tropical guavas, Psidium guajava - especially named varieties, are propagated usually by air layers, and the rarest varieties like Variegated Honey Moon are often grafted, although they will come true from seed (it's just takes them longer to fruit). Both air-layered and grafted plants start producing right away, usually on the same year of planting or next year, depending on growing conditions.
Barbie Pink is a superior variety, very popular among fruit lovers. It produces large aromatic fruit with a bright pink pulp and very few seeds. This variety is air-layered; in our nursery, these plants start flowering and setting fruit in 3 gal containers.
Plant this tree in full sun and provide regular watering, guavas don't like to dry out. Use fertile soil, with at least 50% of compost, and add some soil conditioning components for better drainage: bark, sand, perlite, etc. Mulch well, just make sure to keep mulch 2-3" away from the trunk. Follow our detailed planting instructions that come with every plant, and you are good to go!

The Flower of Gold

By Onika Amell, tropical plant specialist

Q: I am concentrating on adding more fragrance to my garden. I've had great success growing gardenias and I have many different varieties, but their flowers are all white, and I would like to add some colors to my garden too. Are there any gardenias available in different colors? I live in Waipio Acres, Hawaii.

A: Meet the very rare and highly fragrant, tropical Gardenia tubifera Kula or Golden gardenia. Kula flowers change color as they mature, which is a unique feature! Kula flowers start out as cream, then change to yellow and finally to a beautiful gold. In addition to the spectacular flowers, this gardenia also has beautiful, leathery, deep green foliage.
This is a slow-growing and compact plant. Like all the other members in the Gardenia family, the Golden gardenia will do best in an acidic, well-drained, and fertile soil. It will appreciate a good deal of direct sunlight but will be very happy if provided with midday and afternoon shade. As with with gardenias, the more sunlight the more flowers.
It will eventually grow into a rounded shrub if left unpruned, but also can be trained into a small tree, maintainable to a height of under 7-8 feet. Blooms will appear from spring onward. Prune after flowering, this will encourage more flowers in a few months.
Gardeners living in colder areas, do not fret. Gardenias make perfect container plants and can be grown indoors in colder climates. Just be sure to provide high light when bringing them indoors.
The fragrance and changing colors of a Gardenia Kula is unforgettable. They are most fragrant near sunset and during early evening hours. Plant them near walks and patios where their lovely fragrance can be enjoyed.
This rare tropical Gardenia is sure to be a conversation piece in any garden. Great collector's plant!

How to get Strophanthus tree to bloom?

Q: I purchased from you three of these plants - Strophanthus bovinii and I wonder if you could help me. The plants are out of control growing large limbs to the sides and I would like it to grow more upright. Is this possible? Second, it does not flower. What type of fertilizer should I use and how often? How about the watering schedule? I have them in an eastern exposure but possibly they are not getting enough sun? Right in front of them, there is a large tree outside the curb of my house. What should I do about that?

A: Strophanthus bovinii - Wood shaving flower, is quite a unique plant that is very rare in cultivation, this is why very little information is available on its cultivation due to limited experience among gardeners. We have had this plant in our garden for over 12 years and this is what we can advise.
In the nature (Madagascar) it supposedly grows into a large tree, however, from our experience, it tends to be rather bushy, umbrella-like large shrub. Yes, you can train it into a tree by trimming branches growing side-wise, and by removing lower branches. The best time for pruning is early spring when the tree starts new growth and re-leafs (it is semi-deciduous). As far as flowering, the plant is very particular about blooming season, with profuse flowering in Summer (here in SW Florida), however it may produce more flowers sporadically throughout the year.
It thrives in full sun but will tolerate bright filtered light. If a large tree is shading it too much, try to trim some limbs of that large tree to allow more light. Water needs of Strophanthus bovinii are very moderate, so you can rely on your sprinkler system or water once a week for established plants.
You should use 2 types of fertilizers - slow release (once a month) and water-soluble bloom booster (frequent applications are safe):

Chosing a good avocado tree

Q: I'm in coastal Broward County. I'm putting together an order on your web site, and one thing that I would like is an avocado tree. I'd like to have something as close to true "Hass" as possible. Which cultivar does well here in SE Florida, and is most like Hass in texture, creaminess, and flavor? I'm not a big fan of the yellow watery Florida avocados.

A: Mexican type of Avocado have dark skin and buttery texture, while Florida green fruit types (West Indian type, with smooth skin), have lots of delicious melting pulp, so it is a matter of preference.
In coastal Broward county you can grow a wide range of varieties since your climate is very mild, so you don't have select cold-hardy varieties like Winter Mexican, Brazos Belle or Joey, etc. Yet there are many interesting varieties that rare and much more exclusive than Hass, with the same, or even better, quality buttery fruit.

One of the most popular varieties - Brogdon, with red-purple colored pear-shaped fruit, very thin skin, and yellow buttery flesh. It is also very cold hardy.

Very interesting exotic avocado is Kampong - Sushi Avocado - see photo above. The flavor of this fruit very nice, oily, creamy, nutty, reminds of almonds. At the same time, it has solid consistency and if you cut a square it remains a shape of the square. It is the best Sushi Avocado! It tastes great as an appetizer when cut in squares with some shrimp cocktail sauce.

Three collectible varieties:
Anise - leaves that smell like Anise, very rare, the fruit is of excellent quality, creamy and buttery.
Bacon - a large Mexican variety with dark-skinned medium-sized fruits, and a rich creamy flavor. It has exceptional fruit that ripen in late fall and into spring, they are easy to peel and have a light, subtle flavor. Another outstanding feature of the Bacon avocado tree is its angelic sweeping branches which helps keep the tree shorter and easier to pick its fruit.
Nishikawa is a very hot seller! Oval fruit somewhat resembles Hass, but larger, and has very high oil content.

Pretty in Pink... and Purple Prince for her!

By Onika Amell, tropical plant specialist

Q: I have a bare spot in my front garden, behind a low wall, in part-sun. I'm hoping to find an evergreen, flowering ground cover that will cover it quickly. Any ideas on finding something with the ability to eventually also cascade over that wall? I live on Marco Island, Florida.

A: Barleria Repens - Small Bush Violet, is a tough, fast-growing evergreen that blooms from late spring to autumn. Of the many Barleria we see in the tropics, Pretty in Pink is one of the most striking! The name tells the whole story: pretty and pink. A lot of gardeners enjoy using them as a ground cover. They will quickly cover a large area - their stems root readily as the plant crawls along. They are easily propagated by lifting the rooted runners or using cuttings. They also reseed easily. Flowers are followed by seed pots that explode open when dry, dispersing 4 seeds at a time! But perhaps best liked by many gardeners, is their habit to cascade. It will be well suited for covering the bare area in your garden and spilling over that wall beautifully.
When used as a ground cover, remember to pinch out young shoots to encourage bushiness and prune the plant back hard after flowering to keep it neat.
Barleria repens will also adapt to different situations in a garden if you need them to. Although they usually form a rounded to spreading bushy shrub, 2 ft high by 3 ft wide, they will climb when you give them support. They are often allowed to lean into nearby trees and shrubs.
Hardy to 28F, Barleria repens is pest-free and fairly frost-tolerant. They love sun and part shade, as well as well-drained soil and plenty of organic material. Avoid planting it in deep shade as it will get leggy and reluctant to flower.
They will thrive when fed with a slow release fertilizer at intervals of 6-8 weeks, throughout the growing season.

There is another cultivar of this exact variety that has blue-purple flowers, it is called Purple Prince! It couples perfectly with Pretty in Pink! :)

Plants for South Texas and other hot states

Q: Pretty much adore last newsletter. Haven't been buying because our weather here in deep south Texas is so bad it is stunting and killing even the Tamaulipan Scrub! Do you have a cure for that? :) I have every expectation the new grafted Plumeria I purchased from you last year will bloom soon. One of my favorite plants. Thanks again and keep up the good works.

A: Yes, there is a "cure" - using biostimulants that improve drought- and heat- resistance (SUNSHINE boosters), plus the right plant selection. In fact, there is a large number of tropical rare plants that can be successfully grown in hot climates like yours. One of our partners lives in hot and dry Arizona area and has an amazing tropical garden that includes many fruit trees (Mango, Persimmons, Pomegranates, Loquats, etc). Here you can see a few pics from his garden.
Your choice is absolutely right about plumerias. Other easy plants would be Desert roses - Adeniums, and Fancy Euphorbia millii - all these come in so many varieties of colors and bloom throughout most of the year. Our special recommendations for you would be also:

Bougainvillea Dwarf Pixie
Jasmine sambac
Calliandra selloi Pink Lilian
