An exceptionally unique cultivar, Mammillaria fragilis monstrose ‘Arizona Snowcap’ forms bright green, cylindrical stems covered in raised tubercles, each of which is capped with a dense cluster of bright white spines emerging from a white tufted areole. The spines put on an incredible display all on their own – but during the spring and summer months, the snowy effect is amplified by a display of white, star shaped blooms with pale yellow throats. A relatively fast grower for a cactus, ‘Arizona Snowcap’ will produce offsets profusely, establishing a clump of stems reaching up to 5 inches tall and wide.

Like most cacti, ‘Arizona Snowcap’ has relatively straightforward care requirements, chief amongst which are plenty of bright light and a consistently drier soil environment, to avoid issues such as rot that can stem from ‘wet feet.’ To achieve this, be sure to situate this variety in a south or west-facing windowsill where it can receive at least a few hours each day of direct sunlight, and water in accordance with a thorough yet infrequent routine such as the ‘soak and dry’ method. Furthermore, a porous soil within a well-draining pot will provide additional insurance against standing moisture, as will ample airflow.

It is worth noting that the numerous stems of ‘Arizona Snowcap’ are especially fragile, and prone to breaking off when bumped or jostled – either during shipping or once situated within your home! Additionally, this charming cactus is only hardy to Zone 9, so be sure to shield its stems from frosty temperatures to avoid permanent damage. That said – cool temperatures in the range of 45-55 degrees Fahrenheit during the winter months will encourage the most prolific spring blooms, so a seasonal balance between hot and cold is ideal!

All plants are shipped bare-root with the exception of House Plants and Plant Club Subscription Boxes. House plants and succulents will ship from separate locations and may arrive at different times. Orders ship Monday-Friday each week. Please allow 1-3 business days for your order to be processed. We ship within the USA and its outlying territories ONLY. Read our full policy here.

Plant sizing is based on the diameter of the nursery pot (2", 2.5", 3", 4" etc), not the plant itself. Plants may be slightly larger or smaller than the pot they are grow in depending on availability or time of year. While we do our best to ship plants as similar to those pictured as possible, please keep in mind that all plants are unique from one to the next, and display color, shape, and growth variation based on current environment, time of year, and other contributing factors. Please note that we ship our plants as dry as possible in the fall and winter months to prevent root rot or freezing. They will plump back up after planting!

I love to shop here and highly recommend this company. I’ve learned a lot about different succulents and cacti and my garden is beautiful.

We received the packaged succulents and had a wonderful time going thru, finding what cool plants were hiding inside. We then transplanted them into two pots gave them a spritz of refreshing water and admired their beauty.

I really like finding plants that aren’t typically found in my local greenhouses. The plants themselves come so loved, well packaged and ready to be placed.
