I'll start this thread to put up some photo's of the cactus and succulents I have. I have not counted how many I have but I really like small freely flowering types like Rebutia, Sulcorebutia, Notocactus, Parodia, Gymnocalycium, and some Mammillaria. I also like the really small and very slow growing Mexican types like Pelecyphora, Turbinocactus, and Aztekium. I have some Brazilian warm grass land types: Uebelmannia, Discocactus. Argentinian mountainous type: Frailea. This last one I am trying to simulate a biotope pot. I am looking for a spikemoss in the genus Selaginella. I would really like to get the species most found in Argentina, but it is rare plant.
Frailea castanea biotope in the making. I crushed some sandstone to make the potting mix as I wanted the reddish/purple color of the mountainous soil. I use Coir in the mix too. These plants live in the protection of rocks and grasses and have fairly even moisture year round, but in highly drained acid soil. A few of these plants got scarred by a mouse or chipmunk eating them. But that is ok because goats are a real threat to them in their native habitat. These plants will grow back if the underground tap root is not destroyed and form multiple heads. I have seedlings all over this pot now and they are really crowding one another. Just like habitat photo's I've seen.:
Here's a Frailea castanea seedling two weeks old taken Sept 8, 2009. The scale divisions are 1/32". I fertilize with water acidified with Nitric acid to pH 5.0 containing 1.14 gm KH2PO4 per US gallon for the first 6 months, then I up the concentration of KH2PO4 to 3.785 gm per US gallon till they get to 1/2" diameter. I use Potassium Bicarbonate to adjust the pH up if I overshoot the Nitric acid.
Here are the Pelecyphora aselliformis I bought last fall the evening I received them. I had to take a record photo of them before potting. They are 12 years old here.
Here are overview shots of plants that I keep in the cold greenhouse taken April 2, 2010:
These are warm winter plants that don't want temperatures below 50F during the winter and don't want to fully dry out. I still don't have all of these plants home from work yet. The really tender ones are still there. The tall spiny plant leaning over on its side is a Notocactus submammulosus I started from seed around 1987 or so. It is just now getting an offshoot and may branch for me. The bottom is really corky. The mother plant was in a 10 inch pot and just barely fit in a 5 gallon joint compound bucket to carry it. That plant was beautiful and had about 7 branches.
More warm winter plants:
Turbinocarpus pseudopectinatus taken April 2, 2010:
Here it is last year with the flowers open:
Here's a Uebelmannia pectinifera flowering last year. I have not grown these plants well and they are scarred by sunburn. I bought a new one last spring at the Connecticut Cactus show. I am trying to coddle this one and keep it sunburn free.
I have more photo's, but I will have to get them up some other time.
