Croton vs Polka dot plant

Codiaeum variegatum · Hypoestes phyllostachya

Pet safety: Polka dot plant is listed non-toxic to cats and dogs; Croton is toxic (diterpene esters in the latex).

Why these two get mixed up

Polka dot plant is recorded here as a pet-safe alternative to Croton, so the question is usually whether the swap is actually a fair one.

The differences that matter

Pet safety

This is the difference that matters most. Polka dot plant is listed non-toxic to cats and dogs; Croton is toxic (diterpene esters in the latex). If the two are sold under the same name, a mislabelled plant is a genuine risk in a house with animals.

Mature size

Croton reaches about 72 inches; Polka dot plant tops out near 12. Buying the wrong one for a shelf means rehoming it in a year.

Light

Polka dot plant tolerates medium light; Croton needs bright-indirect as a floor. Put the second in the first's spot and it stretches and declines.

Habit

Croton grows upright; Polka dot plant grows spreading. That decides where each one physically works.

Not even related

Croton is Euphorbiaceae, Polka dot plant is Acanthaceae. They share a shop label and nothing else — different families, different continents, different care.

Which should you buy?

With a cat or dog in the house, take Polka dot plant. The other is toxic, and if the shop label is wrong you will not know which you have brought home.
In a dim room, take Polka dot plant.
If you forget to water, take Croton, which goes 8 days between drinks.
If it is your first plant, take Polka dot plant, at 2 of 5.
For a small shelf, take Polka dot plant, which stops around 12 inches.
