I live in Houston and Houston is not a good place to grow longan tree as it very sensitive to cold weather .In the last 7 years we have hard freeze every year that all orange tree and grape fruit are die . 6 years ago my sister in law sent us some longan fruit from Florida that she grows , we ate them and grow seed in a pot ,the tree grow so quick that the roots go through the pot and go deep in soil so I can't move it and have to cut the pot to lets it grow at that spot .Last year I put the stone around and leave a space for tree to grow . It been survival 6 years through winter and this year it start have some fruit , fruit are small right now but I think it will get big by the fall
