1. Bamboo
Estimated price per plant: $45
The beauty of growing bamboo is that it can be planted in containers, thereby taking up very little space. In a 30 x 40 space, you can fit up to 600 bamboo plants in 5-gallon pots, although the largest bamboo species (giant timber bamboo) should probably be kept outside, as they can reach up to 75 feet in height. Nonetheless, the landscapers’ favourite plant is also incredibly popular amongst homeowners, which makes for a large customer base. Considering the price per plant and how many plants a single grower can harvest, this is certainly one of the most expensive specialty crops in the world.
