They have well-trained staff who give you a tour of the nursery and explain various sections. You can ask them specific questions and you're sure to get a lot of information. They also sell a variety of colourful pots, gardening equipment, fertilizers, etc.
There's another section of the same nursery that deals with artificial plants for home decor and also real flowers like lilies, roses, carnation and bouquets. It is also a romantic place to take your date to if he/she is a plant lover!
