Boronia megastigma is impossible to find i have searched all over europe usa and Australia no one has it and if they do they are not willing to ship. Aglaia Odorata and Cestrum nocturnum can be found at http://www.pflanzenkindergarten.de/ you might need to translate as you do not say where you are from plus you can try hibiscus3951 on ebay. You really should be able to find Cestrum in most places to be honest hope that helps

Can't help with the other 2 but I bought my cestrum at Burncoose nursery online. A UK site.

Here is a link that might be useful: Cestrum nocturnum at Burncoose

I would like to breathe some life into this old post, as I also search for the Aglaia Odorata for sale in Europe - but with no luck.

So - can anyone help again as to where the Aglaia Odorata can be bought in Europe? I would be very grateful. The EBAY seller hibiscus3951 sells Aglaia Odorata plants, but they are more likely the Aglaia Sapidina in stead. - I tried ordering at two different times.

The brown Boronia Megastigma has the sweetest, strongest, perfume!
