Mammillaria humboldtii (Mature) – Pink-Crowned Jewel Cactus 🌸🌵

What Size Am I Getting? Let's Break It Down.

We get it—plant sizes can be confusing. Is a “small” the size of a golf ball or a grapefruit? Don’t worry, we’ve got you covered. Below is a quick guide to help you understand what each size means when shopping our plants. Measurements refer to the plant body, not including the pot (unless noted).

Tiny

• Baby plants or starter plugs. May be rooted or freshly cut. 0.5"–1.5" wide.
• Example: Butterwort plug, small seedling

Small

• Young plant, well-rooted, 1.5"–3" wide or tall.
• Example: Aeonium cutting, sundew cluster

Medium

• Established plant, 3"–5" wide/tall. Ready for repotting or display.
• Example: 2–3 year-old cactus, flowering flytrap

Large

• Mature plant, 5"–8" wide/tall. Great for centerpieces or statement planters.
• Example: Dioscorea elephantipes, pitcher plant

XL (Collector Size)

• Rare or mature specimen, 8"+ or unusually large or sculptural in form.
• Example: Caudex giants, multi-head aeoniums
  

📦 Note:

• Pot sizes (if included) are listed separately on product pages.
• Some species naturally stay small—even large ones might only be a few inches wide. Check individual listings for details.
• Photos are of representative plants—your plant may vary slightly (because nature’s not into clones).
