Species Adenium
I've had this desire to collect all the species Adenium plants the past few years. I have just obtained crispum seeds woo hoo. I have one more species left the swazicum. I am finding that some of these required a bit different care and wondered if we could please talk about those differences. Here is what I am finding:
Adenium obesum: We see obesum sold and have all sorts of hybrids so I will not elaborate much on this species. I treat mine like tropicals watering often during the summer months when the plant is in active growth. My obesums bloom most of the summer. During the winter months I give a sip once a month and can see that the caudex that is plump and full of water really is reduced during the winter months as my plants go dormant.
Adenium multiflorum: My multiflorum seems to be growing more slender than my obesum. Strange enough multiflorum bloom during the winter months when the plant has no leaves. I had my first blooms this past winter while the plant was sitting on a window ledge with southern exposure. I am finding this plant grows very slow compared to the other species. I was really torn when mine bloomed about my watering regimen. But, since it did not have leaves I did only give a sip now and then. Mine survived fine with that treatment. I did read that they should not be watered during the inactive growth. I guess my sips were small enough my plant did not rot.
Adenium somalense: I have not had my somalense bloom for me yet. It seems to be easy to grow thus far. It seems to have a normal active growth similar to the obesums and does go dormant during the winter months. So far I have been treating this one just like I have with my obesums. Does anyone have any other advice with somalense?
Adenium boehmainum: This species does not seem to have a large caudex. So far I have not seen mine bloom but sadly I have not seen a lot of growth in this species. It is a very slow growing variety for me. I have been treating this one just like the obesum...quite a bit of water during the summer months then slowly reducing the amount of water during fall/winter and once I see growth beginning my summer water regimen.
Adrenium oleifolium: I just received this plant this spring so I cannot add a lot of commentary. Through research I understand this will be a smaller plant seldom reaching 2' tall. The leaves are long and narrow, which I am seeing on my plant. In my research I also noted this plant is very drought tolerant so I have been careful in the amount of water I have been providing it. Any one else have comments regarding this species?
Adenium socotranum: This is the giant of the species. Even when sowing seeds these seem to be the larges, stoutest growing of the other seeds I grow they do seem to grow very very very slow. Mine has not had leaves until late in the summer months and seems to go dormant just a few weeks after my obesums. I did notice if I watered this species as I did my obesum it would drop leaves making me cut back on my watering. The leaf drop has stopped now. Seems this species has a very short growing season from my observations. Any one else caring differently for their socotranum?
Adenium arabicum: Love this plant, I do not have nearly enough of the different varieties for this species and will make this my next goal once obtaining all the species.
Mine are fast growing, which seem to have a caudex that spread out horizontally. I have been treating my aribicum the same as my obesum only giving them more surface are in a pot to spread out.
Adenium sp. nova (Tanzania): Just got my first sp. nova this spring. Cannot wait to see these babies grow for me. I've done quite a lot of research to determine the needs of my babies and found that it is imperative to keep the caudex/roots under the soil for several years before lifting as this gives the enormous globular caudex. I have been told that since such a large part of the caudex is underground one should pay particular attention to watering as rot could set in very easily. Once I've had more experience with this plant I will revisit this post. Does anyone have any additional information on growing these beauties?
Adenium crispum: Just got seeds so this is a new species for growing. Would like information on this species and any growing experience?
Adenium swazicum: Do not have one yet. Would like information on growing?

Ladylotus, what a terrific topic to bring up. I sometimes find myself lumping them all together when I am talking about them when there are some really large differences. For adults I currently only have A. obesum, but I am raising seedlings of the various types and this information is so beneficial, so thank you. I am glad to see this post and look forward to viewing the forum member replies.

Terrific post, ladylotus! I am so impressed with your endeavor to collect all the subspecies of adeniums. So A. swazicum is the only one you don't have yet...not for long I'm sure.
I would like to contribute to this post eventually. I hope others who live in a wet tropical climate as I do will also pipe in to share their growing cultures and experiences with the different subspecies.

I'm ashamed to say I wasn't even aware of most of these. Would love to see pictures of all of them... hint hint :) Great post though, can never have too much information.

Original Author11 years agoThank you all for your very kind comments. I greatly appreciate them. For some reason I am so enamored with the species. Please note that I am fairly new to them as well and only shared my limited experiences with the ones I have.
Rick, please if you do know of anyone that has the species swazicum, let me know I would pay for seeds or a couple plants. Also, I got a couple seedlings of Nova Tanzania as a friend went to Africa. However, I would love to have seeds of them and would love to share the seeds/expense with you. I will also keep my eyes and ears open.
I will be trying to collect the different varieties of aribicum after I obtain my last species and learn how to care for them. It is such an addiction...ugh. While I know our obsessions could be worse, I cannot seem to be satisfied with the plants I have and keep ordering. I'm so thankful all of you understand.
Please let me know your experiences with these species in case I need to alter my growing conditions. :)

I know I am posting this really late. I found swazicum seeds on Adeniumseeds I emailed them to see if they have any in stock. I also love arabicums and have several varieties growing from seed right now. I am new to Adeniums and want all of them too. I have an A. multiflorum, I have a Nova Tanzania, I have several types of arabicum, I am looking for crispum seeds though. where did you find yours?
This morning I bought some multiflorum seeds online. They are coming from the Netherlands though. I hope whoever sends them hides them in something. Nothing was ever mentioned about a certificate to get them into the states. I am very impressed with the people growing in northern Europe because of the climate. They do an excellent job at growing plants! The seeds also had good reviews!
I am going to check out aridlands and try to get a swazicum seedling an obesum seedling, and Boehmainum for spring. I don't have a straight somalense or Socotranum yet. I had some obesums but they were shipped in soil and rotted a couple days after I got them. So I am nervous about getting the obesum and the somalense.
Do you think the Somalense is more hardy than the obesum temp. wise?
I do have some arabicum x socotranum seedlings at least I am under the impression that, that is what the Black Pearl is.
I am wondering if the A. Olefolium has anything to do with how Ko makes his Mini plants.

My understanding Bob is that the Somalense are not as tolerant of cold and moist.
The Arabicums and Swazicums have been documented to be able to withstand more cool weather.The are a few species that are hard to cross pollinate and I believe with the Mini's that this is a good example of fairly stable seeds. The majority of the MIni's that I have started at different times have all given me the growth and character of the Mini traits.
The A. boehmianum is a cool tree. I love the leaves on mine. So different than that of other specie.
Bob, If you get trees from Aridlands. Mark's "Crimson Star" is usually listed. It is one of his first crosses (Swazicum) that produced such a true red bloom. This tree with it's bloom is stunning. They are grafted, but this tree is so nice.
I got Crispum seeds once through Adeniumcenter from Thailand once many years ago, but the jury is out still as neither have bloomed yet. Thinking that it may be a cross? The bloom will tell more.

I believe that I have a grafted A. swazicum "Crimson Star".

Ladylotus, lovely post about the adenium species you have. Since yours are aleady segregated by species it would be hugely appreciated if you could upload some pics of each type (of your plants and their leaves) so that us novices could use it to ID our mixed up plants which are mostly NO ID. The exotic ones like EBA/Chada petch/thai soco gb etc what are these, would love to know if they are select bred arabicums or something else?
