Note
Please note that the plant will be shipped in its pot, securely fastened with multiple layers of clear tape to prevent any shifting or damage during transit. This ensures that the plant arrives to you with minimal damage, safely and securely. We have been employing this method for shipping plants for several years, occasionally using smaller pots for added safety and convenience during transit. It's important to understand that many plants enter a dormant state during the fall and winter months, resulting in the loss of most leaves and appearing dry or lifeless. This is a natural process, and come springtime, they will begin to regrow and thrive once again. Please be aware that due to regulations set by the Department of Agriculture, there are certain plants and sizes that we are unable to ship to California. We apologize for any inconvenience this may cause.
