Allamanda Species, Common Trumpetvine, Brown Bud Allamanda, Golden Trumpet, Yellow Allamanda

I have had several Allamandas for over 30 years. They are all in full sun, up against a north side fence. I love the flowers, but wish th...Read Moreey could be cut for bouquets. If you cut them, they die within a minute or two.
The thing that surprises me about the comments here are about how it needs to be moist and kept watered. We have never once watered our Allamandas, not even during the spring dry season, when it can commonly go 3 weeks between rains, combined with constant sun and 90 degree heat, yet they get to 8 or 9 feet tall each year and are very healthy and green with prolific flowers.

I love the flowers of this plant, but before I could get it planted in its permanent location, it turned cold (30's at night). I moved th...Read Moree pot indoors, kept it watered, and set a bowl of water beside the plant to offset the dry indoor heat. However, its leaves are turning yellow and dropping off at an alarming rate. What can I do to keep it alive until the weather warms up and I can move it outdoors safely?

I'd had this vine growing in Jupiter, South Florida for several years and when we relocated to Huntsville, Alabama I decided to take a pl...Read Moreant with me...just for kicks 'cause I'm funny like that...
Planted it under a Crepe Myrtle next to the house on the North side, mulched obscenely and watered...left it there.

That was the Spring of 2008.

It didn't do much...and disappeared when Autumn started dropping temperatures below freezing on a regular basis.

After a harsh, wet winter, wicked windchills and lowest readings of NINE degrees, I did not expect to see it again.

Spring 2009. N.O.T.H.I.N.G.
OK, she's dead.

Summer 2009. No, she's not dead! Hello...what's? Yepper. There she is!
The plant is small but healthy as all...no flowers. But alive, rich green leaves...no complaints. I may see if I can divide her and plant a section in another, sunnier but protected micro-climate. But I think I'll wait until next year to give this plant more time to acclimate.

Allamanda grows in zone 7B.

In lahore Pakistan, we have 3 or 4 colors/varieties of Allamanda but this one is hardiest and famous of all. It blooms nonstop from April...Read More till November. And i have it in clay pot of only 12 inches. This is one of those vines which need not to be matured to start blooming. Only 6 inches high and it starts blooming. Blooms are not fragrant though. It needs well drained soil and lots of fertilizer in growing season. In winter it needs a bit of protection but man our winters are mild so it survives easily.

I cut mine Allmanda to the ground right tbe for winter set in . The temp fell to 20 but when summer arrived the plant shot up like wild f...Read Moreire as if nothing had ever happen .

Seed germination went well for me...because of its strange texture and the age of the seed-(3 years), I decided to throw them in peroxide...Read More to soak. I did this 2 days, then I peeled the corky shell off and planted them in potting soil. 2 out of 4 seeds germinated within 3 weeks.
Now I have to ask myself-what will I do with these in my zone 4. I was just checking germination before I gave them away.

I fell in love with this plant when I was strolling through a nursery and brought it home--not knowing a thing about it. Although a clim...Read Moreber, I'm going to try to grow it on my back deck in a pot and house it, during the winter, in a green house. I have taken it out of the ugly black planter it came with and planted in a beautiful basket weave pot: looks beautiful; however, a lot of the leaves are turning yellow. Hopefully, the yellowing leaves will stop after the plant has adjusted to its new home. If someone has a cure for yellow leaves, please advise.

I have two of these in my yard here in SW Florida. One is a very large mature plant growing against a trellis against the front of my hou...Read Morese. The other is against a fence in my backyard. I've had that one for a few months, so it's still rather young, but was about three feet when I purchased it at a Lowe's here in Bradenton.

I don't know about other climates, but it has absolutely thrives here, but its growth and flowering rate seem heavily dependent on its sun exposure. The one in the front gets full sun most of the day; it's become very large, and spilling over its initial trellis with vast quantities of flowers. The other allamanda in the back in partial shade most of the day. It seems to be growing much more slowly, and has few flowers.

I haven't done much with this one but fertilize this spring. It does like water. I find that the one in full sun begins to wilt when it doesn't rain and I miss watering for a couple of days. I may move the smaller one into a more sunny location and see how it fares. They are beautiful and aside from needing regular watering, require little care here in southwest Florida.

Here in the Central Valley of Costa Rica, this wonderful vine blooms continuously throughout the year. It takes a long time for a hardwo...Read Moreod cutting to grow roots, and to produce the flowers, but the wait is worthwhile. Then again, we just cut a branch off and place it in any available space! Doesn't seem to affected by any insects....and we have lots!

I have also seen miniature versions of this flower growing in Hilo

I immediately fell in love with the 1st one I ever saw (2002), bought it and, being end of season, left it in the nursery pot it came in....Read More It was covered during the 19 degree freezes that winter. Come spring, trimmed the dead branches down to the ground, frequently checked for signs of life but found none.

In June the soil was emptied from the pot & the remnant below the soil line was tossed out in the potting area of my yard. 2 weeks later I noticed some green showing on the remnant I'd tossed out so I replanted it.

Today it has it's own place - growing on my back yard arbor. I made a vow to myself & my little plants to never toss any of them out until AFTER June.

This is one of the all times favorite shrubs. It´s one of the most commonly cultivated in Brazil, and still the most popular Allamanda. ...Read MoreIn the tropics, it blooms with full strenght on spring and summer, but it never really stops blooming - in mid winter you still can see yellow flowers here a there.

The white sap is poisonous. It doesn´t prevent attacks from aphids and catterpillars (I see enormous and colorful catterpillars - they are gorgeous - on those plants, and they eat everything - the moth, in other hand, us quite ugly), but is certainly dangerous for kids and animals.

Prune previous season's growth back to 1 or 2 nodes in spring. The stems must be staked and plant must be watered regularly if exposed to a full sun environment.
