Question
I have received a pack of perennials which contains a tuber of the above variety.  Nowhere can I find how deep I should plant this tuber.  Can you help?

Answer
Hi Ann,
Thanx for your question.  The plant's common name is Four O'Clock, originally from Mexico.  Not hardy colder than zone 7.  Plant the tuber like you would a daffodil bulb.  Ab out 6-8 inches deep and you can use a bulb augur which is like a long Drill bit that you can use with your battery powered drill.  I hope this helps.
