We live in northern Pennsylvania, zone 5, and it did extremely well for us. I don't know the extremes of the zones for good growth but as I said it did very well here.

The standard by which gardeners and growers can determine which plants are most likely to thrive at a location. Google zone hardiness and your location to find the dates for your location.

We planted it last year in Southern Maine, and to our surprise, now that the snow is melting in April after a fairly brutal winter, it's springing right back green and lush as ever. Highly recommend this miniclover seed & this brand, we've reordered three times with superb results.

Simply, the country is divided into different growing zones based on their average coldest temperatures. Zone 4 regions(most northern states) have much more lower temperatures than zone 9(very southern states like Florida and southern Texas). Plants are also categorized into how cold hardy they are, in this case Hirt's hardy kiwi plants are able to survive very cold winter temperatures and still recover each spring. Tropical kiwi plants are not able to survive extremely cold temperatures and would not be suitable for colder regions in the U.S. Google"plant zone map" or refer to any state horticulture university for your region's particular plant zone.

at least 7. this is essentially a tropical plant. they grow well. anything under zone 7 will have to be brought in for the winter.

I believe Speedzone Southern is safe for warm season grasses and the regular Speedzone is safe for cool season grasses that are typically found up North.

The lowest temperature it can tolerate is 45 degrees but depending on your zone you can summer it outside and winter it inside. Watch for spider mites and keep in full sun for best results. Most passiflora are fairly hardy.

According to the website "Dave's Garden", it is hardy from Zones 8a to 11. I live in Naples, FL and I planted it in June of 2013 and it is doing fine. It's not the fastest grower in my garden, but, I'll just be patient. Hope this helps. Chuck Bainbridge

What zones can these survive outside in the winter? I am in zone 4 in Iowa.

The Oxalis need full sun to light shade and their hardiness is Zones 6-10, anywhere indoors. If you are in the correct zone, they will certainly come back!

Depends on the climate where you live if you get frost or freezing temperatures don't plant it in the ground.

This plant will grow in zones 4-6. You should be fine with it. It will survive snow. It's a perennial. I haven't even planted mine yet. We have a frost warning for tonight. Crazy weather. I'm using it for around rocks in a rock garden to fill in the spaces. Good luck!

I don't know specific zones, but the website I always refer to (Trees of Joy) advises that low temps of 13 degrees F is enough to damage above ground growth (especially new growth). The author gives methods to protect your outdoor tree in the winter. He lives in SE PA (very close to me, in fact), so he has experience growing the trees in a pretty cold winter climate.

It is hardy to about 20 degrees with a light mulch, but it is important to have well draining soil. Horticultural zone 9 or 8 in a mild winter with extra mulch. I wintered it over in Dallas several years. With a growing season of less than 240 days it would probably not produce substantial rhizomes. It does have beautiful leaves though and could be overwintered like cannas north of zone 8.

I don't know if it will grow in Phoenix, but it does grow beautifully in Rockwall, TX. We are in zone 8. Going into it's second winter and looking good.

In climate zones 9-11 they can be grown outdoors year round although they can become invasive so be aware of where you sow your seeds; any climate zone colder than 9 can be grown as an annual outdoors (or simply brought indoors for winter). They should tolerate average indoor room temperatures fine, just be sure to use soil which drains well that doesn't compact easily and have it where it can get lots of light with some direct sunlight.

It's to tell you where in the U.S. this plant will grow. Check out http://planthardiness.ars.usda.gov/PHZMWeb/ or search for "USDA zone map" to see what your zone number is.

I don't remember where I found the information but it's at least zone 5. It could be hearty enough for zone 4 but you'd have to check a resource to be sure.

It is a single zone but I keep my white wines near the bottom where it is cooler. It works great.
