I would add these links: 1. Wikipedia Houseplants together with the medium in which they are grown can reduce components of indoor air pollution, particularly volatile organic compounds (VOC) such as benzene, toluene, and xylene. Plants remove CO2 and release oxygen and water, although the quantitative impact for house plants is small. Most of the effect is attributed to the growing medium alone, but even this effect has finite limits associated with the type and quantity of medium and the flow of air through the medium.[25] The effect of house plants on VOC concentrations was investigated in one study, done in a static chamber, by NASA for possible use in space colonies.[26] The results showed that the removal of the challenge chemicals was roughly equivalent to that provided by the ventilation that occurred in a very energy efficient dwelling with a very low ventilation rate, an air exchange rate of about 1/10 per hour. Therefore, air leakage in most homes, and in non-residential buildings too, will generally remove the chemicals faster than the researchers reported for the plants tested by NASA. The most effective household plants reportedly included aloe vera, English ivy, and Boston fern for removing chemicals and biological compounds. Plants also appear to reduce airborne microbes, molds, and increase humidity.[27] However, the increased humidity can itself lead to increased levels of mold and even VOCs.[28] When CO2 concentrations are elevated indoors relative to outdoor concentrations, it is only an indicator that ventilation is inadequate to remove metabolic products associated with human occupancy. Plants require CO2 to grow and release oxygen when they consume CO2. A study published in the journal Environmental Science & Technology considered uptake rates of ketones and aldehydes by the peace lily (Spathiphyllum clevelandii) and golden pothos (Epipremnum aureum.) Akira Tani and C. Nicholas Hewitt found "Longer-term fumigation results revealed that the total uptake amounts were 30−100 times as much as the amounts dissolved in the leaf, suggesting that volatile organic carbons are metabolized in the leaf and/or translocated through the petiole."[29] It is worth noting the researchers sealed the plants in Teflon bags. "No VOC loss was detected from the bag when the plants were absent. However, when the plants were in the bag, the levels of aldehydes and ketones both decreased slowly but continuously, indicating removal by the plants".[30] Studies done in sealed bags do not faithfully reproduce the conditions in the indoor environments of interest. Dynamic conditions with outdoor air ventilation and the processes related to the surfaces of the building itself and its contents as well as the occupants need to be studied. While results do indicate house plants may be effective at removing some VOCs from air supplies, a review of studies between 1989 and 2006 on the performance of houseplants as air cleaners, presented at the Healthy Buildings 2009 conference in Syracuse, NY, concluded "...indoor plants have little, if any, benefit for removing indoor air of VOC in residential and commercial buildings."[31] Since high humidity is associated with increased mold growth, allergic responses, and respiratory responses, the presence of additional moisture from houseplants may not be desirable in all indoor settings.[32] sourse: https://en.wikipedia.org/wiki/Indoor_air_quality#Effect_of_indoor_plants 2.Critical Review: How Well Do House Plants Perform as Indoor Air Cleaners? Dingle et al. (2000) reported on a field study of three portable office buildings in Perth, Australia to test removal of formaldehyde by plants. Five plants (five species) were added to each room every two days to a maximum of 20 plants (at 2.44 plants per m2) after nine days. Two adjacent portable office buildings were used as controls with no plants. The mean formaldehyde concentrations were about 850 ppb, except with 20 plants. The authors state that the results show “no change in formaldehyde concentrations with the addition of 5 or 10 plants in the rooms and only an 11% reduction in formaldehyde concentrations with 20 plants in the room.” They did not indicate that this reduction was statistically significant.... With this caveat firmly in mind, it is hardly surprising that the HBI study failed to find any effect on pollutant removal by plants, despite a reasonably strong study design in terms of using controls. The study by Dingle et al. found only an 11% reduction in formaldehyde with the highest loading of plants (20 plants in a room or a loading of 2.44 plants per m2), which is not feasible in the real world and is probably not statistically significant. ... Sourse: http://www.buildingecology.com/articles/critical-review-how-well-do-house-plants-perform-as-indoor-air-cleaners/ I think people overestimate the ability of plants to clean the air. That's why EPA don't write about plants as cleaner at all: Epa wrote about Mechanical air filters, Electronic air cleaners, Gas-phase air filters, UVGI cleaners , PCO cleaners, Ozone generators , Portable air cleaners but EPA don't write about plants as cleaner at all.Sourse: http://www.epa.gov/iedweb00/pubs/residair.html If you use plants as cleaner You need to test air inside your house or flats. You need to use complex devices to test air otherwise you may find that you don't have any benefit from plants at all. And this is only placebo. You can spend your time for nothing. Only complex devices to test air inside your houses or flats can help you. Please don't trust so much NASA or Wolverton. Be critical. To read Critical Reviews too. Сheck the air in your homes with complex devices.

Know what you mean, an office supply store clerk looked at me as if I was from another star system when I said I was looking for onion skin paper and had no idea what typewriter ribbon was (I know I was mean to ask for that but it was fun). I still have a manual and an electric typewriter, but NO ribbon, booh hoo. What I hate is filling out questionnaires/forms by hand instead of a typewriter, my handwriting is so atrocious that in 5th grade a teacher suggested that I should study medicine, since I already had the handwriting for it, LOL.

Thank you very much. Ron, we probably got our Double Whites about the same time. I bought several spinosissimas last year from Vintage, this was one of them. I would not expect suckers this fall. Let it grow :) Celeste, thank you. I would like to have sucker from your rose. Is it fragrant? The main thing that attracted me to Double White was description of its fragrance. Don't remember now where I read about it, but it was compared to violettes, I think. I will send you an e-mail. Olga

Jake.... Welcome to the Adenium Forum. There is also a Cactus and Succulent Forum, and there is even more information posted there too. Here's what I know about Adenium. Seeds: Easy to germinate...and FORGET the photos of flowers! Adenium doesn't bloom to make flowers like photos show. Selected, superior varieties are always grafted onto an under-stock. 99% of all seed-grown plants will produce common, pink flowers of varying merit. NO seed seller can guaranty/predict flower colors, or shape. If they claim that their seeds are superior, and will breed true...they are full of crap! Plenty do, and they are crooks. mgonline...sucks! Top Tropical...questionable reputation. eBay...a crap-shoot, and YOU take the risk.

This is the place for good information. I live in NYC, and it ain't Arizona. Adenium are no more difficult to grow than any other juicy succulent. If you can grow a tender succulent, you will do fine with Adenium. Winter culture will be the problem, if any. Keep, cool, bright, dryish, and take cues from plant. Start to gradually water when new buds show. Hope this will help. Frank Bronx, NYC
