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.

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!

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

TopTropicals.com

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! :)

Triple Sec Mango

By Onika Amell, tropical plant specialist

Q: I live in Mesa, Arizona. I am considering purchasing two of you Triple Sec Mango trees. Can you please give me some information on this variety and how to grow it successfully here in hot and arid Arizona, if at all?

A: Triple Sec Mango is a new name for the superior variety Seacrest. The aroma of this fruit resembles Triple Sec - an orange liqueur. It's a juicy, mid-season variety that has good disease resistance.
Mango has pretty good heat and drought tolerance. It loves sun, but there are a lot of factors to consider when growing Mango in your area.
Check your soil. Soil quality is always first and foremost: when you live in an area of Arizona with hardpan (extremely compacted desert soil) or caliche (layers of soil cemented by calcium carbonate) you will have to learn how to deal with such soil types. Amend the soil as needed.
The best time to plant is spring or fall to give your Mango a chance to get established before the really intense Summer heat starts. Alternatively, protect the tree with a shade cloth. Tender, new growth will not stand a chance unprotected, especially newly planted and/or young trees.
Mangoes are tropical and sensitive to frost and freeze damage. Young trees especially will also need winter protection when temperatures go near or below freezing. Always plant trees in a location where they will be protected from cold wind. Consider staking your newly planted Mango trees for the first year. It's never a bad idea to even stake during periods of high winds.
Make sure your planting site has very good drainage. Always use a good quality mulch around your tree as it helps to trap moisture, keeping the ground and the roots beneath it cool. Keep mulch a couple of inches from the trunk of the tree. Avoid a location that gets full day sun. Morning sun, afternoon shade is ideal. Give regular watering until the tree is established. Once established, water only when the soil feels dry.
Fertilizer with a Mango-Food. A foliar spray of micronutrient solution is always recommended during the active growing period. Use plant stimulants and microelements to improve cold hardiness and vigor.

Fruit tree size and production

TopTropicals.com

Q: I am interested in a Strawberry Tree... does this tree produce fruit while still small or do I have to wait until it is large before it produces? Should I fertilize it so it produces sooner? I ask because my garden is not large and I prefer to keep my fruit growing trees in a smaller size. Also, how big is the fruit and does it have a seed?

A: Strawberry Tree, Muntingia Calabura, is one of those fascinating fruit trees that starts flowering and fruiting in small size. We have plants growing in 1 gal containers that already have flowers. This tree is nearly year-round producer providing warm conditions. It is a fast grower, although a compact tree when mature, and can be trimmed to desirable size without affecting production.
Muntingia fruit is one of our favorites. It is super sweet and juicy, and the seeds are tiny small, not bigger than the strawberry seeds, so you don't have to spit them out. The fruit size normally about 1/2 inch, but we have a tree in our garden that produces almost cherry-size fruit! See picture above. The secret is, good watering and using fruit booster - SUNSHINE honey micro-element supplement. We also fertilize our fruit trees using Fruit Festival and Mango-Food fertilizers.
