Size and Shipping

Size Definition

Most plants are shown in 2 Inch pots (square), 4 Inch pots (round or square), 6 Inch pots (round), and 8 Inch pots (round).

The Size option, such as 2 Inch, 4 Inch, etc., typically represents the size of the pot that the plant is shown in. In most cases, it does not represent the width, length, or height of the plant, with some exceptions:

- Monkey Tail Cactus: The size represents the length of the cactus

- Some columnar cactus / cacti plants

- Certain plants that are shown without a pot

Letter Suffix in Size

When a letter is added to the size value (Example: 2 Inch #A or 4 Inch #B), it represents different variants of the same size. The meaning could vary depending on the type of plant. The corresponding listing photos of each size variant provide the best representation of the plants that you'll receive.

The letter suffix could represent one or more of the following:

- Differences in plant maturity and/or fullness

- Differences in plant size and/or shape

- Differences in style and/or color

- Differences in amount of variegation

- Unrooted cuttings vs. rooted plants

Packaging & Handling

Vast majority of our plants shown in 4 Inch or larger pots are shipped bare roots (See below fore more details).

Most plants shown in 2 Inch pots are shipped in their original plastic pots with soil because they are small and are less subject to damaging during transit.

We carefully wrap each plant with wrapping paper and place them securely inside the box. Then, we fill the remaining space in the box with newsprint paper, air pillows, or crinkle paper to ensure the plants don't move around during shipping, and hence minimize shipping shock.

Shipping with Pots

The plants listed below are shipped with the pot and soil to ensure that they can stay healthy through transit:

  • Most plants shown in 2 Inch pot (exclusion applies, some 2 Inch plants are shipped bare root to provide better protection)
  • String of Pearls in 2 Inch and 4 Inch pot
  • Variegated String of Pearls
  • String of Hearts
  • Variegated String of Hearts
  • Plants shipped with pots and soil

Shipping Bare Roots

Shipping bare roots and soft paper wrapping provide the following benefits:

  • Prevent broken parts, fracture, scuffing, and fallen nodes/leaves
  • Minimize residual moisture within the package
  • Prevent soil getting into the leaves and causing a big mess
  • Reduce shipping weight and the cost that our customers pay

Feather Cactus: A Little Mound of White Detail

Feathery-looking white spines give Mammillaria plumosa its charming common name, Feather Cactus. Rounded stems can gather into a little mound, bringing a soft-looking texture to a cactus collection.

  • đŸ€ Fine white spines give the plant a feather-like appearance
  • đŸŒ” Rounded stems can gradually form a clustered mound
  • 🌾 Small pale flowers may appear when the plant is mature
  • đŸŒ± Seed option is separate from the live-plant size options

Choose a live plant to enjoy now or the listed seed option for a growing project. Handle gently; a soft appearance does not make cactus spines safe to touch.

Care Tips

Light: For established plants, provide bright, filtered light with gentle sun introduced gradually.

Water: Allow the mix to dry between moderate waterings during active growth. Keep almost dry during cool rest.

Soil: Use a freely draining cactus mix with plenty of mineral grit.

Potting: Choose a pot with drainage holes and repot when the roots need more room.

Humidity: Provide good airflow and avoid persistently damp foliage.

Temperature: Protect from frost and cold, wet conditions.

Seeds: The 10 Seeds option contains seeds rather than a rooted plant. Germination and young seedlings need separate care; the established-plant watering advice above does not apply to them.

Shipping & Handling

The 10 Seeds (77-95°F) option is a seed purchase, not a rooted plant. The live-plant shipping terms below apply to the plant-size options.

  • Most plants are shipped bare roots without the pot and soil, with the following exceptions:
  • We commit to shipping bare roots, which requires more time and labor, and provide excellent quality and service to our customers - see Benefits of Shipping Bare Roots
  • You will receive a very similar plant to the one shown in the photos; shape and color may vary
  • Ship within USA & its outlying territories only
  • Please visit Order Processing & Shipping info page for additional details

Care Instructions

Please visit our Succulent Care info page for more details.

To ensure the health of succulents, it is important to plant them in porous, well-draining soil. Succulents require little watering, but don't like to sit in wet soil. To create an adequate cactus mix, simply add pumice, perlite, or grit to cactus soil to provide the proper drainage.

Allow the soil to dry to the level recommended in the Care Tips above before watering again. Always drain excess water.

Weather Conditions

  • When ordering, be mindful that living succulents can freeze. If you live in an area that is below 40°F, please consider purchasing plant until the weather is more suitable.
