Alessandro ~ I am sorry you have not received an ID for your plant.
I was looking at my A. striata and still wonder if the size of the leaf is affected by the age of the plant, the size of the container or perhaps the nutrients/ moisture received.
If you do not mind, I would like to post a photo or two of my Aloe striata. I have had this plant since 2006. When I received it it was tiny and I would not have believed it would grow as large as it has. I have removed it from the pot and cut the roots back, repotting it twice since I got it.
The lack of teeth on the edges of the leaf and the white border as well as the striation pattern in the leaf are indicators of the ID.
The color of the white border begins to turn pink when temperature drops. Mine has never bloomed but the coral color of the bloom is the reason this plant is also known as a Coral Aloe.
Hope you won't mind the photos... Kristi
