Juniperus virginiana is a species of juniper native to eastern North America, from southeastern Canada to the Gulf of Mexico, east of the Great Plains. In its native range, it is commonly called "cedar" or "red cedar," names rejected by the American Joint Committee on Horticultural Nomenclature as it is a juniper, not a true cedar.
This one pictured is from a rocky slope in Northern Kentucky. This type of juniper is rarely seen in bonsai. Next spring this plant will be placed in a smaller pot. For sale.
In the wild, apples grow quite readily from seeds. Apple trees are an example of "extreme heterozygotes", in that rather than inheriting DNA from their parents to create a new apple with those characteristics, they are instead different from their parents, sometimes radically. This is why there are more than 7,500 known cultivars of apples.
Crape myrtle makes an excellent bonsai due to its exquisite branch ramification and ability to reduce its leaf size. It gets its common name from its crepe-like, crinkled petals. This can even be successfully grown as an indoor plant.
This one is very old. I have two of these old barberry bonsai. Both are for sale.
Rarely seen in classical bonsai in the past, the barberry is slowly gaining poppularity as a container plant. This barberry bonsai produces tiny yellow flowers early in the summer followed later by tiny red fruits. The plant is also covered in tiny needle-like thorns.
