When it comes to plants, pricing is usually based on two factors: size and rarity. How big is it, and how hard is it to find? When it comes to cacti in particular
, they’re super slow growers, so smaller is more economic for customers and suppliers.
They're also very unique looking! Cacti can come in all shapes, colors, and sizes, and some look almost unreal, alien-like. Definitely different aesthetically from tropical plants. If you're an East Coast native, there's that West Coast appeal. We're so far removed from the sun and desert that cacti are really unique.
Cacti are easy to care for since they're succulents (from the Latin word succulentus
for juice or sap), and are defined by their moisture-storing capacity. Botanically-speaking, the term succulent refers to any plant that has evolved adaptations to survive hot, arid environments (like a cactus has to survive the desert). This means a cactus-owner can go weeks—maybe even months during the dormant season—in-between watering their plant. That's really attractive to someone who wants plants, but doesn't have a ton of free time to devote to them.
One thing to note, though, is that cacti need a ton of natural sunlight. Don't get a cactus unless you have a super sunny, dry spot to put it in. Think of their native habitat, a hot/sunny/dry desert."—Erin Marino, The Sill
