Chrysanthemums is the real name. Lavender Cremone Mums is the common name. The flowers are long lasting at least 14 days the most popular types are: Button , Daisy, Cushion, Spider and Micro Spray & Santini’s have multiple blooms on a stem. Disbuds are single large blooms, and Spray Mums have multiple smaller blooms per stem. Clean water and clean vase and recutting every couple of days will make them last a long time in a vase most. The lavender color is available year round but wise to order at least 10 days in advance because we don’t always keep these in stock.
