Special Notes about Japanese Red Maples:
All of our Japanese Red Maples have been grafted for a more robust tree altogether. We use a Japanese Green Maple rootstock to encourage the overall Maple bonsai tree to be more disease resistant and have a longer lifespan.
If you receive one and you notice green leaves close to the base of the trunk, please remove them to redirect the tree’s growth hormones to flow to the top of the tree. This will stimulate the tree to produce more of the red leaves that you desire within several weeks during the spring and summer months.

Japanese Maples are a traditional favorite for bonsai lovers all over the world. With their dynamic visual differences every season, it's always something new to look at with maples. Especially their famous colorful transitions as they shed their soft foliage during the fall months. They do that to get ready to hibernate for the winter since all maples are deciduous trees.

'Emperor One' or 'Emperor I' also goes by 'Red Emperor' but that moniker tells you how majestic this Japanese Red Maple variety is! In spring, the leaves sprout a bit later than other maples into an extremely deep maroon purple-red with a brilliant translucent sheen that gives the foliage a nice shiny look as the sunlight hits them. Throughout summer, the foliage has a rich dark red color on top and an olive green underside but has a vibrant scarlet red fall finish when it gets ready to drop its leaves. During the winter, you can see its blackish-red bark better. Emperor One is well known for its longer leaf retention since it buds its foliage roughly 2 weeks later than other typical maple varieties to avoid some of the late winter frost.

'Emperor One' is a hardier variety of maple as it better tolerates hotter and colder climates more than your average maple bonsai tree. However, due to its soft thin leaves and small size to be enjoyed as bonsai, please be cautious and provide some shade to avoid any leaf burn throughout the year. When maples are kept small, they are much more sensitive to their environments than their large yard tree counterparts.

Note that all pre-bonsai trees will come in a plastic nursery growing pot.

For Deciduous Trees:
Please note that during the mid to late fall months, deciduous trees will lose all of their leaves/foliage to go into dormancy for winter. They will have barren branches and will be extra sensitive to shipping stress during mid-fall and all of winter. If we try to ship them during this dormancy time, it is considered extremely high risk. We reserve the right to refuse to take orders for these trees during their dormancy period from around October to February.

House of Bonsai reserves the right to delay on shipping any live plant order by several days; in order to attempt to decrease the high risk of major shipping related stress that may shock the plants during extreme weather conditions (too hot or cold). If we are purposely delaying your order because of this, we will notify you via email. Before you submit an order, please be mindful of your local weather and time of year. If there is major damage (ex: plant is dead or many branches are broken), please contact your third party shipping carrier (ex: USPS, FedEx, UPS) to submit an insurance claim with them as we are not able to assist with that matter. The fault is with the third party shipping carrier for such damage since it happened out of our hands. We are not responsible for any damages after the order leaves our facility since they were out of our control. If the bonsai tree is still alive but weakened due to shock (leaves are yellow-brownish or leaves have fallen off) then we are happy to assist in proving post-delivery plant shock care instructions via email to revive the plant. Please notify us by email of the issue within 48 hours upon receiving the order in hand. Please email us at houseofbonsai@gmail.com with your Order # and the keywords "Shock After Delivery" in the title so we can assist ASAP.
