There are also island planting zones that, because of elevation differences, are warmer or cooler than the surrounding areas and are given a different planting zone designation. Note that many large urban areas carry a warmer planting zone designation than the surrounding countryside.
The map-contains as much detail as possible, considering the vast amount of data on which it is based and its size. If you see a hardiness zone in a catalog or plant description, chances are it refers to the USDA map. Click here for more information about hardiness maps.

Blog , Tips , Tutorials. Now I do. This is a great place for beautiful plants. I was wondering if I could put these with my sun flower plants as the combo would be magnificent. What time of year to start the planting we are at the Ides Of March and ready for some fun. Aina Haina Alu like dat. About how big can my garden be or how small? How about the soil we are kinda sandy but then we have volcanic soil too.
Any advice would be applied. Mahalo -John Fitzgerald. Ok, well. Sorry to hear about your loss.

I have read many posts here and I see people having the same problems that I did when I started growing poppies. You have to realize that you are farming and you have to dedicate a hour or two everyday in your garden.
Everyday you need to water, weed, protect from animals, high winds and cut off dead lower leaves when the plants fruit to keep the stems dry.
When the plants are cabbage to bolt stage they need to be fertilized every two weeks. Most problems are from plant spacing. Plants that are planted too close together will not let air circulate enough to keep the lower stems dry which leads to stems getting soggy and the plant dies from damping off fungus. I tried using an Earthbox one year with amazing results until this problem happened to all the plants at the same time. The problem is that potting mix is always damp in an Earthbox and poppies need well drained soil.
Timing is critical, you have to plant at the precise time for your location. That's why climate zone maps were created. Zone maps are tools that show where various permanent landscape plants can adapt. If you want a shrub, perennial, or tree to survive and grow year after year, the plant must tolerate year-round conditions in your area, such as the lowest and highest temperatures and the amount and distribution of rainfall.
To help develop the new map, USDA and OSU requested that horticultural and climatic experts review the zones in their geographic area, and trial versions of the new map were revised based on their expert input. Compared to the version, zone boundaries in the edition of the map have shifted in many areas. This is mostly a result of using temperature data from a longer and more recent time period; the new map uses data measured at weather stations during the year period In contrast, the map was based on temperature data from only a year period of However, some of the changes in the zones are a result of new, more sophisticated methods for mapping zones between weather stations.
These include algorithms that considered for the first time such factors as changes in elevation, nearness to large bodies of water, and position on the terrain, such as valley bottoms and ridge tops. Also, the new map used temperature data from many more stations than did the map. These advances greatly improved the accuracy and detail of the map, especially in mountainous regions of the western United States.
In some cases, they resulted in changes to cooler, rather than warmer, zones. The USDA map is the one most gardeners in the eastern United States rely on, and the one that most national garden magazines, catalogs, books, websites and nurseries currently use. This map divides North America into 11 separate zones. In some versions of the map, each zone is further divided into "a" and "b" regions.
