There are similar restrictions on food. Within the EU there are few restrictions, unless there are outbreaks of plant or animal pests. If traveling to countries like the US or Australia, you must check before you decide to buy something to grow or eat.
This small tree (above) is an acasia subspecies and is found outside the Yumbo centre in central Playa Del Ingles. This is a very robust species and will sprout relatively easy, as I found out.
Look at this little plant (right). It is an offspring of the tree by Yumbo centre, that I planted in a large pot in my kitchen window, shared with an agave americana.
It took only two weeks to sprout. I have had this species before, and I know that it grows very quickly and is very hardy.
So now I have one living memory from the Canary Island. I wonder what else will sprout? I will keep you posted.
