Question
I live in Copiague, NY 11726.  Where can I purchase a crape myrtle bush?  I would like to put it close to the house.  Will the roots grow into my foundation.  I have about 6 feet to the right of the front living room window I was thinking of putting it there.  My arborvitae died from the salt water of Sandy Storm. I live on a canal.  If this is not a good choice what would you suggest?  I love the look of the purple crapes.

Answer
Hi Anna,
Thanx for your question.  Because I don't live in your area, I can't advise on where to purchase the crape myrtle but you're in a good zone for one to grow nicely.  You should be able to locate a suitable shrub in your local nurseries and even some of the big box DIYs like Home Depot or Lowe's.  I would go with a local nursery first.  Also, the people at the Suffolk County Extension Office - Master Gardeners can probably give you more precise advice.  Here is a local contact.  I hope this helps.
Tom
