The easiest plant to sell would be the succulent plant, it’s easy to grow and maintain and small enough to have a large stock. But price-wise you’re looking at $5.99 – $20 each. If you’re looking for big profits, grow and sell Saffron ($2,500 per pound), Bamboo ($150 per potted plant), or Ginseng (a single root can cost up to $17,000). Of course, these vary in easiness to grow, Ginseng being harder to cultivate just right, but worth it for the price tags!
