Please rest assured that many customers select First Class Mail with the confidence that the plants will arrive safe. This is due to the way we wrap each plant individually and also  include extra paper in the box for padding and insulation.
First Class Mail can take 7-10 days and is not guaranteed, but is generally okay for succulent orders Spring-Fall, especially within the Western United States.
We do recommend Priority Mail service for all house plants and Hoya shipments year-round and for all succulent shipments during the winter or extended hot/cold periods.
