Datura: a fragrant treat for tropical or indoor garden

Q: A few years ago I purchased Datura from you and it was doing well. As a matter of fact I took cuttings and propagated new plants. Now they have markings on the leaves and I do not know what it is. Any remedy?

A: Generally, Datura is a bi-annual plant, unlike its close relative perennial Brugmansia that grows for many years. Which means, Datura is short-lived (2-3 years maximum for the same plant) although it seeds easily and is a very fast grower, reaching from seedling to 4-5 ft size in a matter of couple months.
At this time of the year, markings on the leaves may be a result of normal aging (the plant may already exhausted its natural cycle) in combination with a cool weather that affects the leaves and overall look.
Here at Top Tropicals we especially love this plant and keep up with propagating new plants every few months. Propagation may be by means of seeds or cuttings, but seeds are always better for stronger, longer-lasting Datura specimens. A lot of times you will notice little baby seedlings around the Mother plant, even if you think all seeds has been harvested.
Just continue growing younger plants from seeds, and Datura will always be with you in your garden to bring you joy of showy scented flowers. It makes a great houseplant too!

The Rolls Royce of House Plants: Medinilla

...This is an extremely showy tropical plant with bunches of bright pink blooms that will flower for months on end. What a stunning and colorful plant! Showy should be its middle name. It is one of those plants that truly evokes feelings of elegance and drama...
Medinilla apoensis - Philippine Pink is particularly rare and hard to find in the trade. The flowers on this particular Medinilla is not hidden underneath so it is not necessary to grow it in a hanging basket like so many other species. It is a tall upright grower that will flower throughout the summer. For all you obsessed collectors out there, do not hesitate. This Medinilla is not in many US collections. The plants we have right now are at least 1-1.5 feet tall and are blooming size. Wink wink ;)

EASY GROW-BOX

How to quickly germinate tropical seeds in winter

Q: I live in the New England area where the winters are very long and dreary. I plant both a veggie and flower garden during the warmer seasons and am especially fond of growing chili-peppers. On account of most chili's longer growing seasons, I need to get already established plants in the ground as soon as the weather is warm enough. My problem is that despite my best attempts to germinate and grow seedlings ahead of time - even in my sunniest window - I just can't seem to keep the soil evenly warm enough to get them to germinate, no matter how warm the room is kept. And on the occasion they do come up, the seedlings always seem to remain weak and stunted, likely owing to the especially low humidity of winter. I also tried using an electric seed-starting heating pad, and the results were only a little better. Are there any tips you could give me?

A: Yes, I understand your issues and can sympathize! While it might be surprising to some, even here in sunny S.W. Florida, there are long stretches of winter weather where the ambient temperatures are simply too cold for germinating many of the more tropical seeds, such as the notoriously warm-weather chili-peppers. Also, I am likewise a fan of chilis, and always have at least a few different kinds growing at any given time. I have two great suggestions...

Plumeria cold protection

Q: We have a purple-flowering plumeria which resides on our sunny deck during the warm months and then Winter vacations on our back porch where we can close the plastic film windows and where it stays above 50 degrees (overnite) until it can get moved outside again. We live in zone 8+ in South Carolina and I would love to plant it outside. Do you think if we ghost-covered it when alerted that we would have an overnite freeze, that it would survive being planted in the ground and recover to flower when warm? I don't believe the soil in our yard has ever frozen below the top 1/2 inch or so, and never for more than a few hours at a time. What do you think?

A: Plumerias are tropical plants, which means, they need frost-free environment. Even if the ground is frozen only on "the top ½" or so"- this may be enough to kill the plant. From our experience, plumerias can withstand a few hours of windchill frost (not frozen soil), but even if they survive, they may get some branches damage, and recovery may take so long that the plant may not even bloom the next year. So I wouldn't take that risk even with a ghost-cover cold protection. We have customers who grow tropical plants in the ground in colder areas, but they have greenhouse protection: this means, the soil is warm and the air temperature is maintained above 45-50F. For example, this Greenhouse in Virginia.

We recommend to continue growing your rare plumeria in container and move it inside when temperatures drop below 50F (recommended) and for sure when they drop below freezing. Plumeria can take a cold night (a few hours of upper 30's) as long as it is followed by a nice warm sunny afternoon with at least upper 50s. Otherwise, keep it indoors. The good news is, since plumerias are deciduous and have no leaves in winter, low light level won't affect the plant.
Just make sure to minimize watering and keep the plant on a dry side until it starts growing new leaves in Spring. You may continue fertilizing once a week with half-doze of Sunshine boosters - Sunshine TotalFeed. This will maintain the plant healthy and prepare for the blooming season in Spring.

Hardy Dwarf Red Jade Vine

by Onika Amell, tropical plant specialist

Q: I simply adore Jade vines. I think they are the Queens of all the vines! I have been very been successful growing the green Strongylodon macrobotrys and purple Jade Mucuna pruriens vines here in Clewiston Florida but I am struggling to make the Red Jade vine (Mucuna benettii) thrive. It keeps dying on me during cold snaps. Any suggestions?

A: ...Here is our solution for you. Consider growing a Dwarf Red Jade Vine or Camptosema grandiflora. It is closely related to the regular and ultra tropical Red Jade Vine Mucuna benettii but much tougher and hardier. It is considered to be one of the more cold hardy of the Jade Vines...
This gorgeous, rare and unusual vine is a sheer showstopper. It is easy to grow and it will reward you with long fiery chains of dangling orange-red flowers that bloom from late fall to early spring. Even though it is listed as a dwarf do not be fooled. This vine will get quite large and will need a strong support over time. The flowers are long and heavy and will show best when planted on an arbor or pergola where they are able to hang down and wow you and your visitors. It puts on a wonderful display. Butterflies, bees and hummingbirds will all thank you for growing this stunner!...
