PlantFiles: Mandevilla, Pink Allamanda
Mandevilla x amoena 'Alice Dupont'

I have 2 of these. One gets morning sun and one gets afternoon sun. The morning sun seems to be the best. The one getting the afternoon sun did well all summer but mid to late September it started to suffer from the strong heat and sun where as the one with the morning sun is still strong.

I have grown and lost and grown again this beautiful vine - one year it blooms and the next it dies. I use pots. This year (2007) I have three of them, two pink and one white, and they are all blooming nicely. Along with consistent watering, I'm now using a time release fertilizer (Osmocote) and Miracle Grow potting soil. I think I've found the right combination. I'm about to purchase my favorite, but most difficult color (yellow), so I'll soon see for sure. North of Houston, The Woodlands, zone 8B.

I bought 'Alice Dupont' one year ago, planting it into a large pot where it has flourished and grown beyond the supporting wires. This week I decided to plant it out into the garden to allow it to climb freely. I was stunned to find the pot was full of large tubers most of which I had to remove in order to replant it. This was an inordinate amount of tubers given it was merely one year old.

My concerns are that here in Queensland, Australia, we have to be careful we do not introduce plants that will become invasive to the detriment of our natives.

'Alice duPont' Mandevilla - What a beautiful plant! Trumpet pink flowers amid textured glossy large green leaves, amazing looking when blooming or not. I purchased it at my local nursery and repotted into a larger pot with a trellis for it to cover. It's August 2006, our weather is warm and ideal for this plant.

Then.... light green catepillars eating up the plant, yikes!
So, starting spraying with organic BTK, as suggested, and have them under control, I think...

Now... no flowers, not a one, and wondering when they will re-appear. I live in San Diego, California and it sits on my patio with partial sun. Most of the time the bottom part is in the shade as my small patio fence is facing west and the plants pot is on the other side, but it does receive indirect morning sun and direct late afternoon sun on top portion. The soil is moist, but alas, the flowers aren't blooming and when trying I think, they are stopped before they develop.

I have taken my plant inside to an unheated attached garage.Placed near the door. cut back about 6 in. do not water it until i slowly get it use to the warmer weather. Don`t place it outside too soon. I have kept the same one for several years. I have been told to root prune(I can`t understand this). wonder if you can start new plants from the potato like bulbs. I think the attached garage is warmer because I had one die in my shed.

I have two 'Alice Dupont' growing outdoors in zone 9 on two colums. one on each side of the front entrance of my house. they bloomed all through the winter until a rather sudden and unexpected shift from 70 degree weather to below 40 degree weather followed by a couple of light frosts burned the leaves. no major damage though, it continues to grow rapidly.

I have grown this vine for many years now but last year was the first year I got it to live over to the next. I always grow them in 20 gallon pots. I do not know if the very few light frosts get them or if our heavy 3 months of winter rain does them in.

I love them though, they are fast growers and covered in blooms all season long. I always get a light case of aphids on them in late summer. They are easily killed off though with soapy water.

Working landscaping in Michigan, I ripped this beatuiful flowering vine late in the season at a funiture co that just wanted everything taken out and cleaned up after an overnight low of 29 in the latter part of October (record breaker.)

It was still in full bioom and just breathtaking to look at. The root ball was out of the ground about an hour or so then I stuck it in the ground watered it in and went back to work. not thinking too much about it. Three or four days passed and the weather had gone from 70 to 40 and cold rain set in.

I found this site and just sat back and laughed when I foud it to be a zone 10 or 12 tropical, but in the cold rain I went out and potted the two of them up into big square patio pots. NOW 2 months later they have stopped blooming and are putting up with the warm dry heat I have been misting them 2 or 3 times a week. I really thought they were goners, all the flowers and most of the leaves browned and fell off but today I have new shoots coming up from the bottom out of the soil as well as new growth on the vines as well, wish me luck!

This plant has a beautiful pink bloom with a yellow/pink throat.
I grow mine in a spot with afternoon sun and seems to do fine. Also is very slightly scented

I grow Alice in a container every year and let it frame my garden shed. It makes it up to the peak of the roof by fall and is completely charming and easy. I start a new one each June because we have a very short season and the temperature fluctuations in my woodstove heated cabin are more than it can take over the winter. I've never had any insect problems, and I live in the moth capital of the universe.

I have three mandevillas. Two are doing great. I have two 'Alice DuPont' plants. They are both in the same type of container, in the same place. One is growing like crazy and the other one isn't doing anything anymore. It's stopped growing. I have fed it, watered it, checked it for insects...and it still will not grow.

Extended bloom, easy care, patio container, tropical, woodland garden. Great choice for trellis or arbor. Ice pink with darker pink throat. Each flower lasts for several days. What a beautifull choice. Such large flowers, I just had to add it to my climbing collections.

My 'Alice Dupont' Mandevilla seems to be growing well but all the new buds just seem to turn brown, dry up and drop off.

Have experienced the same catapiller problems. Don't have a good solution - I'm afraid I stoop to commercial pestisides - and be quick about it as they will munch right through the entire vine in a few days.

I agree with the other gardeners!!! This is a beautiful vine and quite easy to grow. I have only one problem with it--- late in the season it gets "worms or caterpillars" which totally destroys the plant for the rest of the season.

I have 'Alice du Pont' - very well known with pink flowers, and very easy to grow.

I absolutely love this and any and all mandevillas!! Everyone at the nurseries kept telling me they needed full sun, so I wasn't sure if they would like growing on my rod iron balcony railing, getting morning and late afternoon/early evening sun, but they love it!!! I have 3 different varieties and 3 different shades of pink from almost white (can't remember the name?), to pale/light pink (alice du pont), to dark pink (hot pink something?), growing inter-twined, along the balcony over my front door, and it's so beautiful, people always ask if it's real. The best part is, as they drop their flowers at the end of the day, it leaves a welcome mat of fresh flower petals to greet my family and friends!!

I'm in Zone 8, San Antonio, Texas, and my mandevillas' soil is neutral (between 6.5-7.0), and they love Superbloom about twice a month. I mist them sometimes on hot afternoons, and keep their roots protected with heavy mulch. Moist and cool and comfortable.

I love how easy this plant is to grow, and how splendid it looks in bloom. Since it is a tropical, it will have to come indoors for the winter in my zone 6b. I will try to remember to post next year how it does inside a somewhat dim, dry, heated house over winter.
