PlantFiles: Violet Allamanda
Allamanda blanchetii

Blooms profusely spring till fall, very hardy in our heat of south Texas. Receives the most praise from visitors to my garden.
I have three plants that are 4 years old, this last fall before putting them in my greenhouse in october, I noticed there were spike covered large oval pods on two plants. I cut one off and left the other on the plant. The one left on the plant just recently turned brown and popped open this week to expose about 14 seeds. I would like to know how to plant these seeds and if others have experienced the same thing with their Allamanda's. I have not been able to find out anything from local nursaries or books.

This is still a not very popular Allamanda, although it grows more vigorously than its cousin Allamanda cathartica. The dark red flowers highlights it from the other Allamandas, for sure, and could as well used in landscaping combinations with them.

As other Allamandas, its sap is poisonous to kids and pets, but it doesn´t prevent catterpillars and aphids to infest it from time to time.

I have this plant for two years now. It grows well in full sun (it is planted under my kitchen window - southern exposure).

When I purchased this plant, I also purchased a Mandevilla - I liked the combination of the two. Late in season, however, I noticed that these plants were overwhelmed with worms (they kind of look like caterpillars), which totally devoured every leaf on the plant. Try as I might, I can not get rid of them. This spring, I decided to do away with both; however, the Allamanda is coming back in full force.

Nothing but pleasure from this beauty, which I started from a single terminal bud cutting, coaxed out of a Mexican restaurant while I was on vacation to Cancun. It blooms profusely in a bright, yet indirectly lit spot. If you want an exotic houseplant that is stunning, long-blooming, and easy to grow, try this! Just keep it warm. :) Mine bloomed 2/3 of the year in my warmest room, in Zone 7.5... The images are of plants grown in a rainforest dome in Zone 9, so unless you have a greenhouse or a bit of the tropics, your results may be less wild. I got 1-2 blooms at a time, from Feb-Sept. I had to sell my 5 yr. old plant in Sept.(at a fair price) to pay some huge medical bills. But I saved seeds and plan to start over!!
