You will notice that we have several varieties of tea. The common question people ask is "what is the best one?". The answer depends on your reasons for growing tea. If you are serious about growing tea and they are going to be trained and used just for tea, then any variety will work and it won't matter much what they look like because they will all be prunned and trained for the purpose of growing tea.
But if you are growing the tea in your landscape as a flowering ornamental, that's when variety may come into play. Some plants may be more vigorous, the foliage may be larger or the flowers may be a different color. This is when it comes down to just personal choice.
Our named varieties are all identical within the variety. They are actually clones of the mother plant. All San Francisco Tea are genetically alike. All Amelia Tea are geneticall alike and so on. These selections are grown from cuttings. Each of our varieties have varying characteristics such as growth habits, foliage types and even flower color.
If you don't care about variety, then I would suggest the Nature's Select Tea. This is not a variety, but a collection of plants all grown from seeds. There can be slight or vast differences in the individual plants due to each one being genetically different. Plants grown from seeds will have a unique characteristic called a tap-root. Seedlings can usually handle stresses better than plants grown from cuttings.
