Yesterday I found a box of two asparagus plants among some bags of bulbs at a local store. I couldn't open it, so I don't know what they look like, but the box was about 6 inches tall and 3 inches front to back. Although I have a lot of experience with flowers, this would be my first vegetable. I've been told they're not easy to grow, but I'd like to try, especially because asparagus is so expensive to buy!
The box said both of the plants were male, as did all of the other boxes on the shelf. I assume that's important to know, or else it wouldn't have been made clear. What's the difference between the male and female? Does it matter when it comes to growing? Would I need some of each in order to produce a crop, perhaps for the purpose of pollination? If so, is there a certain way I should position them in the garden?
