What the............???

Watertown, NY

My leaves have been checked by several experts at our Cornell University outreach center. First all said they had never seen a brugmansia, but then they all had different opinions. Over fertilizer being the most common. I fertilize all of my plants the same, so that is why I think the culpret could be the pro mix. i comes with fertilizer in it. i am wondering if this bag might have gotten too much in it. These plants all cam from the same grower, the same day. All have been through extreme weather ups and downs, but only the ones I potted that day in that soil are the ones showing damage. I have 4 more from this grower, also gotten the same day as the rest and they are getting huge and they look wonderful.

again,my B.sanguina looks just like that after fertilizer of any sort.

Here are some pictures. Ugly but descriptive. Growing fine until the heat.

No this is not mites. They had been treated and leaves put under a microscope. The 1st 2 are on the sides and the one in the middle untreated with sevin dust. I thought this was pretty dramatic.

Annie, the sanguinea and vulcanicola hybrids growing here is the same way as you describe for yours. I never fertilize them much, and especially, if there is vulcanicola in the mix, strong fertilization can kill them. I have wondered much about, why that is so. Species like suaveolens and insignis is often found growing in tropical rainforest on riverbeds, where the air, soil are hot and humid, and the soil is rich in nutrition from decomposed plant materials.

The habitat of vulcanicola is different. It might be so that sanguinea and vulcanicola originally had the same type of habitat, but in the case of sanguinea, this species has been planted out for at least 10.000 of years by humans. The original habitat for the both of them is semi-dry areas, where the soil consist of vulcanical gravel (lava broken down to gravel and sand). This might explain a lot about, why they resent fertilizers and why they need to be kept on the dry side, when watering them Both grow at elevations where the air is cold and foggy. From a cultivated situation we know that in order to bloom these plants need a cool to cold environment and a lot of humidity to surround the plants

Thanks so much..that's so informative,. Ive wondered why my sanguinea's don't like good soil either. They thrive on sand and rocks,and if i amend or add even a handful of worm casings... she gets crinkled droopy and yellow. Does Calif. have less brug disease problems than elsewhere? Ive been growing them for 10 years without a Caterpillar,beetle,aphid,grasshopper,slug,etc. in sight. (knocking on wood)I am all organic,but if i had a bug on my brugs...i might not be!!!again,Tonny,thanks so much,its a pleasure to learn here.

Annie, may I ask what is the brug's pix.? It's charming, an unusual slender shape trumpet, and the coloring is lovely as well.

Tonny;
Vulcanicola brugs.? It's brand new to me haven't heard of them before. Please tell me more.

Lily love
Thank you.
its the
B. sanguinea i keep talking about which crinkles and shrivels from enrichment.
It seems to glow from within,doesn't it?

Lovely! I've seen them on mail order catalog, but just simply called red blooming angels. Thanks Annie.

Several hybridizers are working on a brug that looks similiar to Annie's, one that will grow in the South for us down here where it is hot and humid for a good part of the year. Right now, just enjoy the photos of those who are blessed to grow them!!

To get back to the diseased, or bug-ridden, or whatever, leaves-

ZZ, I did check, the whole plant's stems, down to the ground, and no holes. There were a few healed lengthwise splits, no more than 3" long, in the stems, which I think happens from rapid growth????

I'm about ready to cut the plant down. My DIL looked at it and said, why don't I just trim off the diseased (old-growth) branches. That may work if it is bugs as a temporary fix but the new growth is still sprouting off the main stem that is coming from the ground, if it is nematodes or a virus.

Still haven't done the sevin.

Kim, they are much like B. sanguinea, but have smooth leaves and fruits with a lot of warth-like bumps on them. Usualy vulcanicola is considered to be a good species, but they might in fact be a subspecies of B. sanguinea. Vulcanicola has been found on a few locations in the south of Colombia, but are fairly good represented in the North (west) of Ecuador. They grow about 3.000 altitude, where the clouds and fog often touch the ground and the climate is frost free, but bitterly cold.

According to Holguin recently, all plants thought of as vulcanicola are in fact vulcanicola x sanguinea hybrids. This shows, because the larger part of fruits from a (seemingly) vulcanicola plant gives seedlings similar to sanguinea or heavy influenced by sanguinea. Both sanguinea and vulcanicola has been used by shamans for thousand of years to induce visions, but sanguinea was often sowed out in large plantations, vulcanicola not. The reason was that vulcanicola was so poisonous that many shamen died using it, so it was left to grow on its own and didn't follow the geographical movements of the local tribes.

Here is a picture of one of Holguins plants taken in 2007 by a tourist visiting Quito botanical gardens.

I am not currently able to confirm that this is Holguins 'Violet', which gave the bluish tint to the European vulcanicola and x flava hybrids, but it fits the description.

How interesting! Thank you, both for sharing such valuable info. on the type of brug.

so interesting. Thank you.

You are welcome :)

This summer I am going to test, how the Islandic lave stones will affect the plants. These are lava stones, which I am going to crush down in small fragments and to size 0.5-0.3 mm gravel. These are sold from danish aquarium shops and used to build up aquariums for Malawi Chiclids.

Tonny, you are a brug wizzard! You explain it so well. I feel lucky to have seen the pic you posted above and so enjoy learning from you. Thank You..
