Lay two plants next to each other — uses, risks, and whether either has a grow guide.
LegalDeadly
Foxglove
Digitalis purpurea
The spotted thimble that became digoxin — a poison-garden teaching plant, not a homegrown heart tonic.

palpitations, poor circulation
In favor
Teaches why some garden plants became drugs

Bloom in year 2 (~400 days) as an ornamental — never as a drug
LegalToxic
Comfrey
Symphytum officinale

Symptoms
bruises, joint pain, minor wounds
In favor
Exceptional compost and mulch plant
Against
Hepatotoxic internally
Days to harvest
60–90 days to a leaf cut (external / compost only)
