Euphorbia lactea is native to Africa. This is a Euphorbia lactea crest. A crest is a mutation that occurs in nature - you cannot make it happen - it is very desirable. The crest will continue to grow. Occasionally it may put off some normal growth, which is just typical columnar Euphorbia growth. Some people will cut off the normal growth so it does not take any energy away from the crest growth. You do not have to cut the normal growth off.
This is the exact plant you will receive.
This Euphorbia is in a 6" plastic pot. All of our plants are shipped bare root (carefully wrapped with no soil). We have a care sheet to give you tips on caring for succulents - contact me for a copy.

When you re-pot this plant, do not use a pot much larger than 6" diameter. If you put a succulent in a pot that is too large, the soil will take too long to dry since there are not enough roots to absorb the water and your plant may get root rot.
What is the difference between an cactus and a succulent? All cacti are succulents, but not all succulents are cacti. Succulents are plants that store water in their stem, leaves or root system. A true cactus has a structure called an areole. It looks like a patch of cotton from which spines, flowers, branches and roots grow. While some succulents may have spines, they will not have areoles.
