Like adeniums, pachypodiums are 'fat plants', which have large caudexes used to store water in dry conditions. These plants are endemic to Africa, with many species found only in Madagascar, or the island of Socotra in Yemen. I first discovered these plants while researching adeniums. I was instantly drawn to their large caudexes and eye-catching spines. There is a fair amount of information on these plants online, but their taxonomy is still an ongoing area of research, with new species being discovered all the time. There is a huge amount of information on these plants on Wikipedia, as well as on pachypodium.org, a site dedicated to preservation and cultivation of this amazing genus of plants.
Like many of my plants, I got these from Le Jardin Naturel in March 2015. I had 3 of the 4 seeds germinate, and they've been doing well ever since. They are just starting to show signs of developing their spines, now that they are just over half a year old. As of March 2016, only one is still actively growing, whereas another has just exited dormancy. The third has shrivelled some, and it is currently unclear as to if it will survive.
Native to Western Madagascar, this species will grow to 1-2 metres in height, and will produce white flowers with yellow centres once mature.
Yet another plant from Le Jardin Naturel. Only 1 of the 4 seeds recieved germinated, but it has been going strong. I particularly like its red trunk! It lost all of its leaves following transplantation out of its previous pot which retained too much water (algae was growing between the rocks), but as of March 2016, it has just exited dormancy and small leaves have reappeared.
P. baronii hails from Northen Madagascar and has short conical spines. It likes lots of light and water during the warmer months, but the soil must be well draining - if the roots are soggy, the plant will die. In the spring, mature plants produce bright red 5-petaled flowers.
This plant also came from Le Jardin Naturel. Only 1 of the 5 seeds that I recieved has survived to date, but it is currently doing very well and seems to be thriving under my grow lights.
This species of Pachypodium is native to Madagascar where it grows on bare rocks with little water and a lot of sunlight. Unlike many other Pachypodium species, P. decaryi lacks the large thorns that most other species possess. Mature specimens can grow to be over 40cm around and several meters tall with large white flowers.
Like so many of the others, this plant also comes from Le Jardin Naturel. Only one of the seeds has survived to date, but it is currently quiescent. The picture shows a single remaining leaf, however it lost that leaf not long after the photo was taken and has been dormant ever since. I continue to water the plant occasionally and am vigilent for any signs that it might break its dormancy.
P. geayi is one of the many tree type species of Pachypodium. They can reach hights of up to 6 metres in the wild, and come from South Western Madagascar. I obtained my seeds from Mr. Kevin Spears, the owner of pachypodium.org. As part of his mission to perserve the plants of this genus, he makes his seeds available for sale on ebay for reasonable prices.
I have had great success growing this species - nearly every seed I planted germinated and has survived to date! Once they reach ~1 year of age, I will transplant the seedlings to their own pots - provided I have the room.
This is another tree-type species from Souther Madagascar, though this one can apparently reach up to 15 metres in the wild. The flowers are said to be pale pink. My plants are still quite young, so I don't expect to see flowers for many years. I also obtained the seeds for these plants from Kevin Spears' ebay store.
This species was only described in 2005 by Jonas M. Lüthy. It is found near Toliara in Madagascar. It is another tree-type species, growing to a height of 6 metres. This species produces large white flowers with a yellow throat.
I bought these seeds from Kevin Spears' ebay store. Only a small number germinated, but 3 are more than enough - I don't have space for more. Especially as there are still more species that I would like to get and grow!
This is a fast-growing, tree-type species. It has small conical spines, and may reach up to ~9 metres in height when fully grown. I have 3 of this species, however only one is truly thriving. A second has leaves and is exiting dormancy, but the third is rather stick-like at the moment. Close observation shows some green at the meristem, so fingers-crossed that it exits dormancy soon!
