Genus guide
Raphanus — 14 species
Part of the Cabbage & mustard family family (Brassicaceae)
Raphanus is a small Brassicaceae genus of fast-growing edible root crops, anchored by the cultivated radish (R. sativus) and the weedy wild radish (R. raphanistrum). All species thrive in full sun — at least six hours of direct light daily — and prefer consistently moist, well-drained soil; they bolt and become pithy if allowed to dry out or overheat. Toxicity varies across the genus: cultivated radishes are generally safe for pets, while wild radish can irritate the digestive tract of dogs and is toxic to horses. Always verify the specific species before assuming safety.

Are Raphanus plants toxic to cats and dogs?
Most Raphanus are pet-safe. Of the 14 Raphanus species we cover, 9 are non-toxic on the ASPCA list and 5 carry a toxic or mildly-toxic rating. Even so, confirm the individual species before trusting it around pets.
How much light do Raphanus plants need?
