This flowering vine is very common in Panama where I live. Many people have it planted in their yards. While it seems to grow faster in the tropical lowlands it does well for me at 1400 meters. The vine needs support and it is best to tie it to some kind of trellis. I tried to root it at various times without success. Recently it had seed pods with seeds so I planted three seeds. Two of them sprouted readily so I now have two vigorous seedlings in pots. I have harvested more seeds which I hope to plant soon. This vine has very attractive flowers and here it is in flower 365 days a year. In the dry season I water it. It has grown up to the second floor of my house. It is about 6 years old. I have a small pool with a waterfall below it and there are always some of it's flowers floating on the water. At the base of the vine I have planted some Heliconias. Where I live is frost-free (zone 11). I would highly recommend it if you live in the tropics.

I have grown one of the red dipladenias (learned from reading earlier comments difference from mandeville) for four years now and loooove this vine. It grows great for me in full sun, which is about 6 hours/day in my yard in the Triad region of NC. I usually have to water at least every other day. If I buy a small plant in the spring, it may reach 15 feet by fall and be covered with profuse blooms all summer.

This is the second year I've over wintered a vine. I bring it in when it gets cold. Both years I waited too long, until close to frost temperatures (once it was after the 30 deg. temps, but still salvaged the vine) and the vine shed terribly when I brought it in. It was autumn in my kitchen, green leaves falling everywhere the next few days until the plant was almost bare. So both years I pruned the vine way back, which was probably a good idea irregardless. I leave it in my kitchen, in my sunniest window, which isn't all that sunny, and supplement it with some CFL lightbulbs, about 150-watt incandescent equivalent, and water a couple times/week (it's pretty pot-bound by fall but I don't transplant until spring). I don't feed it. I get a bit of growth over the winter but no blooms. Last year I started feeding in the spring and used a fertilizer high in nitrogen. Oh my gosh, I couldn't figure out why I had no blooms, but the vine took off like it was on steroids. I had the largest and bushiest mandeville I'd ever seen. Later I found out you need to use a fertilizer lower in nitrogen, and higher in phosphorus if you want flowers and not green growth. Once I switched fertilizers, it started blooming. This year I think I will repot and start fertilizing for green growth now and then it will be big and bushy when I put it out to bloom when it gets warm enough. Of course, I'll have to double up on the light bulbs at minimum. Anyways, I don't know if what I'm doing is "right" or not, I'm only sharing what has worked for me (and if it ain't broke......).

If you like bright flowers, you can't beat this vine for ease of growing (I kill stuff......... year #5 trying to grow lavender, wish me luck, retrying some other things like phlox and columbine, too) and volume of blooms.

I bought a Mandevilla Boliviensis last summer for the sunny west facing window of my appartment. Unfortunately it wasn't a very bright summer in Dublin, Ireland (53 deg Northern).

It was doing okay, so I gave him some tomatoe food as I read it wanted somewhere. For whatever reason, I'm not sure, the leaves turned brown and fell off. I have not been able to bring it back to life since.

Symptoms are:

Potted up when purchased, complete with bamboo (Was growing well), Continued to grow, was fed NPK 5.5.10, stopped growing. New leaves and shoots turned brown and fell off, established leaves never died.

Watered soil out thuroughly and next year (9 months later) put in a very sunny location. Showed good indications of climbing but then for no reason and no feeding, same browning of leves and climbers occured again.

Moved out of sun, no change to date.

I love the plant, his name is Douglas, but he doesn't seem to do well under my care.

Any advice?

My mandevilla is BEAUTIFUL. I wanted a red one, but instead I got one that flowers first an unctuous light pink color, and then turns darker pink the next day. This is my first time growing them but Even after only 3 weeks I would certainly buy one again. It seems to be sensitive to full, hot sun (I think I am seeing some sunburn spots) but oh my gosh I love this vine

Grown in large pots in the summer, this year I put the pots in the cool dim basement after I cut the vines back to 6 inches (before frost). I added a cup of water to each pot just once during the 5 months they have been downstairs. Today I brought them upstairs and they have small sprouts from the base, and some short fresh green vines from the older pieces.

Two weeks later I now have a dozen new sprouts on each plant. I've fertilized lightly.

So the bottom of my Mandevilla is dropping leaves (they don't like wet feet).

Love this plant. Have 1 red riding hood and 1 alice du pont planted at trellis together. I too was cutting the vines that swung in the breeze, until I found accidently that, that is where the flowers come from-was pleasantly suprised. I am also now finding that quite a number of leaves are browning and falling off, dont know why, but it has lots of flowers. I also wonder if it has to do with winter coming on. I dont notice any insects but I did notice an improvement when I sprayed insecticide a couple months ago. But now its Dec. and doesnt seem logical to spray plants with bug spray, maybe Im wrong. Hate losing these leaves though. Anybody help? One other note, I was sure I was going to lose my plant when new it definitely looked like it was dying. Thats why I bought a second one about 5 or 6 months later. It took quite a long time for both to become established..

I have two of the most beautiful vining plants with deep, georgous green foilage..and delicate, creamy blooms. I highly recommend this plant to new gardeners. Here on the coast of South Texas, I did have fierce battle with Japanese Beetles and Carpentar Ants. I am a firm believer in Neem Oil for both of these pests! My plants are encumbered with blooms..and the light, sweet aroma wafts on the air as we relax by the water garden.

I've kept it in the same pot and found it tough, not wilting , always in bloom once started.

I bought two white Mandevillas for pots on my porch; one of them is growing and blooming like crazy and the other is losing leaves and the buds are falling off before they open. I water them equally (lately every day, as we've had record-breaking high temps here in N.O.) and they both get alot of sun, although the sickly one gets a little more afternoon sun. I have no idea what the problem is, but generally Mandevilla does very well here.

To address the Mandevilla dropping leaves issue:
Re-potting can be enough of a reason for the Mandevilla to enter a bit of a slump. It will perk up if it is in good lighting. It can also droop or drop leaves if the sun is too strong.
I have had an awful time with aphids on my plants as well. For that reason, I almost never place my Mandevilla near other susceptable plants. I still give Mandevilla a positive rating because it's a beautiful, relatively easy to care for plant.
Somebody correct me if I am wrong, but I believe that Mandevilla might be deciduous and needs a dormancy period every so often? So if your plant just starts to randomly act weird (especially in Fall/Winter), it could just be in need of a pruning and some rest.

I live in southern Australian, in a mild-warm climate. I just bought a bright-red Mandevilla the other day and re-potted it when I got it home. Almost the next day, leaves started turing yellow and falling off. It's still in bloom (magnificent color!) and the buds are still there but am concerned about this problem. I've looked at the other growers' notes on this, but some say it probably needs more water, and others say it probably needs less. I water it every day, as its summer here and hot.

Any suggestions?

Positive Toxicodendron On Nov 13, 2004, Toxicodendron from Piedmont, MO (Zone 6a) wrote:

At a time when most taxonomists are eager to further divide plant species, I don't understand why they lumped mandevilla and dipladenia into the same category. The plants are VERY different in appearance. One has large, rippled leaves up to 6 inches long and 3 inches wide, with large blooms in pink, light pink, or white. It is the traditional mandevilla.
The other plant has small, smooth, shiny leaves up to 2 inches long and smaller blooms in more intense shades of hot pink to red. It was called dipladenia. I have this latter type.
I have found the best time to propagate the vines here in Missouri is mid-summer. I put cuttings under plastic and they root fairly quickly. Mine continue to bloom all winter in the greenhouse, and all summer in the landscape.
Both types get much taller than listed in the details...about 10 to 12 feet for both. Of course, you can allow it to loop back down on the trellis to keep it at a lower height.
Also, for those who are new to this plant: Don't cut back the long, stringy tip growth that appears. This will set leaves and flower buds after a while. (I kept pruning mine back to keep the plant compact, and then wondered why it would not bloom!)

My response says neutral but it's not the fault of the plant.

I planted my pink bloom mandevilla in a large brick planter with a large trellis above it. It was BEAUTIFUL, then started looking quite ill. On closer inspection, I broke open one of the woody vines and it was filled with carpenter ants! My hubby sprayed it with carpenter ant killer and they are all gone, thank goodness, but the damage was done.

I cut all the vines down to the nub and after some weeks of shock, I have about 3 foot long vines now with healthy looking leaves.

You may have to do a similar drastic thing with the aphids - kill them completely and cut off all the damaged areas and cross your fingers.

Another positive besides the beauty and rapid growth - - - the deer don't seem interested in eating my mandevilla. Hooray!

This is to answer the leaves yellow and falling off problem, perhaps overwatering might be the problem.With regards to aphids and such, in my experience, I have discovered a natural pesticide/immunnity builder call neem oil.If you get it in concentrated form it is inexpensive and really works, it kills the eggs of the pests before they have a chance to hatch and boosts the immune system of the plant but do not spray actual flowers.The flowers don't like to be coated with the stuff-it stains them but it makes the leaves beautifully shiny.

in containers, water every day, balanced fertilizer. a few leaves started turning yellow, now about a dozen are yellowed and dropping off. It's mid July.... time for it to start going dormant? When does that happen for this area?

I love this plant and don't want to lose it...have matching pair. These flowers are so pretty and perfect, they should be illegal! ;-)

I purchased a Mandevilla last year and overwintered it in a pot in the basement. I transplanted it in April/May (after the last frost) to a southeastern exposure next to my house.

It's a prolific climber and needs a trellis or other form of support! Blooms have developed in threes and seems to enjoy the pine straw mulch used to maintain moisture. It also attracts hummingbirds!! Another nice addition to the yard. I am going to try to overwinter with heavy mulching outdoors this year.

Dipladenia is also known as Mandevilla, named after the 18th century British diplomat and gardener Henry Mandeville. It is a native of South America. particularly the Organ Mountain forests near Rio de Janeiro.

Additionally, it is also known as Dipladenia mandevilla, and the genus Mandevilla includes plants that were formerly called Dipladenia.

Botanically they are all Mandevillas, but tradionally this plant has been called Dipladenia, having smaller leathery leaves and have very little climbing habit.

Usually they are grown as a container plant or a semi-hanging basket. The original Dipladenias were a very pale pink flower and were discovered in the highlands above Rio de Janeiro.
