Many succulent varieties are only available seasonally because of their propagation cycles. During the growing season, we can usually restock sets and trays weekly. Most individual plants will go in and out of stock through the seasons, but they are also restocked weekly when available. Thursday is usually the best day of the week for finding plants in stock. Spring and summer are the best seasons for availability in general. Any product that is out of stock has a field for an email address on the product page. Enter your email address and click Subscribe to be notified when it's back in stock.
