Tiger Bark Ficus (Ficus Retusa) makes an excellent indoor bonsai. Don't confuse them with the potted Ficus you see in plant stores. All Tiger Bark Ficus on this page were grown and trained in China.
This is a great bonsai subject. They will live with all day or very little direct sun, but given the choice, they prefer at least a few hours a day. Avoid direct mid-day sun in the middle of summer. Their small leaf size, speckled bark and great branching make them a great addition to any bonsai collection
