The purpose of this web site was to add some useful information to those of us wanting to have beautiful gardens in the northern states. My mother taunts me each year when she picks her lettuce in January and I'm looking at 2 feet of snow and have to wait 4 more months before I can even put a seed in the ground.  

I look through everyone of these sites and will make my best effort to only list useful links. There are thousands of sites that will sell you anything. I'm hoping to steer people towards the ones that actually provide information.  

Cornell Plantation - Although Cornell has the great attribute of free labor it does still show what grows in this area as well as pictures and names.

http://www.northerngardening.com/ This fellow from Minnesota has some good tips.

InfoRochester.com  Some good photos of the native plants. I've also used his photos on some of the flower photos. 

National Gardening - Dictionary - This is a great way to find the common name and botanical 
name for plants.  The site is worth perusing for other useful info.

Gardencom.com  - Garden Directory site. 

The Lazy Gardener - This one I have to say I really like! It's succinct, pretty and anything starting off with "lazy" for gardening has got to be good.  Here's her description: A place for people who love to garden, but don't always have the time or the inclination.

My Deer Garden - This one wins hands down for the best deer resistant ideas, plants and designs.  I agree with her that many people (like my own web site) will just list the plants that are deer resistant.  But her site gives detailed information on this along with many other helpful aspects like garden designs.
