|
| Clump grass which forms colonies of plants with dense, blue-green leaves. Flower spikes are tan to purple. Extremely drought tolerant, thrives in full to reflected sun, as well as part shade. Remove dormant foliage and flower spikes in late winter to spring. Cultivar `El Toro`tm, has dark purple flower spikes. Native to southwest U.S. and Mexico. | |

(Zone information) | |
|
|
What are zones, what zone do I live in and why does it matter?
In the botanical realm there are many zone maps that assist us with
determining whether a plant will survive where we live. Through
gathered information it has been determined in which areas a certain
plant should grow.
LandscapeMart is based in Phoenix, Arizona. There are several different
zone maps that are used here. These include:
| |
|
USDA (United States Department of Agriculture's) Plant Hardiness Zones
| |
|
This system is based on the cold hardiness of each plant and divides
the entire country into 11 zones. Phoenix is in zone 9.
| |
|
Plants listed with zones 5-9 mean that they should grow in zones 5 through 9.
| |
|
Sunset Climate Zones
| |
|
This system covers the 13 Western States and is broken into 24 zones.
Phoenix is in zone 13.
| |
|
Plants for Dry Climates Climate Zones
| |
|
This system is developed for Arizona which is broken into 3 zones.
Phoenix is in the low zone.
| |
|
LandscapeMart uses the USDA Plant Hardiness Zone Map since it covers the entire
United States. This allows us to expand our plant catalog to cover the
entire country.
Note that some plants that are listed for zone 9 may not actually grow in
Phoenix due to our summertime heat. The AHS (American Horticulture
Society) has developed a plant heat zone map based on the average number
of days above 86 (30C) which is the temperature in which plants
begin suffering physiological damage from heat. Phoenix is zone 11.
| |
|
A plant may have the numbers 5-10, 7-3. With this number range the plant
will survive the winter cold in zones 5 through 10 and the summer heat
of zones 7 through 3. This plant should not live year round in Phoenix
due to our summer heat.
| |
|
Plants may grow outside of the zones listed. Microclimates can extend the plant's
adaptability and allow it to florish in an area where it normally isn't found. It is
best to contact a local nursery or landscape professional to verify how a
particular plant will grow in your area.
