They not only grow back, each have developed unique features that surpasses the height and shape these flowers develop. One example, this summer a single Celosia bloomed as an exact replica of a minora. Very strange yet fun and exciting. Hey there Tony, thanks for commenting here. I bet the unique features are really lovely, feel free to share a photo … Read more ».
Many people claim they are useless because they are not accurate and have to be improved. It is a simplified system, meaning exactly that — simple. One simply has to know how to use the data, as you said above. I have developed a small tool to do the research, … Read more ».
Hi Matt, Bonnie was correct! We ARE heading into an ice age because the greatest global two-year cooling event of the last century just occurred. From February to February the latest month available global average temperatures dropped 0. Statistical cooling outliers garner no media attention. The global average temperature numbers come out monthly. I must be too old…but I thought I was in zone 5? Not that Matt or any posters here may have the answer to my original question but please lmk if anyone knows if bamboo … Read more ».
Wish I could read the map…. If you follow the links under the map, you can explore the interactive map for your growing zone in full detail, or download a high resolution map for your area. I know some places seem to be warmer but we are going through changes and we are actually going into a cooling trend!
Unfortunately solar minimum is a brief, temporary phase in the solar cycle, so any cooling effects we experience will be temporary. My back lawn went dormant too, it happens during the hottest times of the year in my experience, but the roots are alive and kicking!

Zone 7 contains many different growing climates, from the Eastern coastal areas through the Oklahoma prairies to the arid regions of the southwest and up into the forests of Oregon and Washington. Many Zone 7 hardy plants can be grown successfully in multiple locations with adjustments made to address their specific needs. Frost and early spring cold snaps can damage young vegetables. Providing row covers or cold frames can help protect against early spring or late fall damage. The long, hot summers, combined with the milder winters provide ideal growing temperatures for almost all vegetables.
Although artichoke can be grown as an annual starting in Zone 4, in Zone 7 this decorative and edible plant becomes a perennial favorite. Add to your planting list:.

Zone 8 is considered one of the warmest plant hardiness zones for a large portion of the southern United States. Extending up the western coast, Zone 8 features average minimum winter temperatures of 10 to 20 degrees F. With hot summers and mild winters, growers typically enjoy a long planting season. Zone 8 can expect minimum average temperatures of 10 to 20 degrees Zone 8a has a minimum average temperature of 10 to 15 degrees F Zone 8b has a minimum average temperature of 15 to 20 degrees F Each of the two subzones can experience harsher temperatures depending on weather conditions.
Plants hardy for Zone 8 love mild winters and long, hot summers. With a wide range of moisture and sunlight requirements, growers should narrow down a potential plant list first by zone, and then by specific growing climates. Many gardeners in Zone 8 grow vegetables three times a year, especially with the aid of cold frames and row covers. Cool weather plants like spinach, lettuce and peas can be grown in both the spring and the fall. Even your summer vegetable harvest can be extended by planting every two weeks.

Long, hot summers and mild winter conditions make the heat more of an issue than the cold in this zone. Tropical plants with low water requirements thrive in Zone 9. Because of the extreme heat, spring gardening begins much earlier and fall gardens produce much longer than in other zones.
The extreme heat of the summer breaks the vegetable garden season into winter, spring and fall gardening, versus the stereotypical summer gardening. Most areas will only produce peppers, okra and extremely heat-tolerant vegetables during August.
Instead of considering the cold hardiness, growers in Zone 9 actually need to consider the heat tolerance of certain plants. Apples, pears, peaches and cherries require colder weather than Zone 9 provides. Instead of these popular fruit options, consider planting the following citrus and tropical fruit trees:. Certain cool season herbs, such as cilantro and parsley, may be grown throughout the winter in Zone 9.

Tropical plants are the highlight of Zone With long, hot summers and warm winters, Zone 11 growers need to look for plants that are heat tolerant. Traditionally cold season plants, such as pansies and spinach, will have a limited growing season in the even the coolest part of winter here which is rarely cold at all.
Plants native to the area have the best chance of surviving the heat of summer. Vegetables often started in late spring or early summer can be planted in late winter in Zone Gardening happens year-round with the rotation of plants according to the temperature.
A few cool season vegetables appropriate for winter gardening in Zone 11 include:. Growing herbs in Zone 11 can be difficult because of the extreme heat of summer. Many will not produce seeds due to the heat, so they must be planted as annuals during the cooler months. Some herbs you can begin planting in early spring include:.
