This is one of my all time favorite garden catalogs, Old House Gardens. I love heirloom flowers, and they are just the source to find them. They only sell heirloom bulbs. You will be amazed at what you will come across in their selection.
They have the most gorgeous sketches of flowers in the catalog This is the back of the catalog
The front page tells you all about the company and even has a nice little picture of all of them, they look like a fun bunch!
They have an amazing selection of narcissus, some extremely rare bulbs.
It breaks the catalog down by Spring/Fall planted bulbs. They have 4-5 pages of Dahlia's in this catalog...needless to say I was like a kid in a candy store when I saw all of them. Hopefully by the fall I can add several more dahlias to my collection.
You can order a catalog from their website for $2. It is well worth it. They have a very informative website. It tells you when and where the bulb was found and how rare it is.
So go check it out
