September Sun Kolomikta is a cold-hardy female kiwi vine bred to thrive where traditional kiwis struggle. This Actinidia kolomikta cultivar handles winters in zones 3 through 9, making it one of the most frost-tolerant kiwis available to northern gardeners. Unlike ornamental kiwis, this variety is specifically selected for disease resistance and performance in maritime climates, where salt spray and humidity typically cause problems. The vine produces delicate late-summer flowers and develops the characteristic foliage of kolomikta varieties, though it requires a male pollinator to set fruit.

September Sun Kolomikta stands apart for its combination of genuine cold hardiness and disease resistance, traits rarely paired in a single kiwi vine. This female cultivar blooms from June through September, extending the ornamental interest across the growing season. The designation 'female' means it produces fruit when pollinated by a compatible male kolomikta vine, offering northern gardeners a real shot at harvesting homegrown kiwis rather than settling for ornamental foliage alone.
This is an ornamental vine first, fruit-bearing second. While female kolomikta vines produce small, edible kiwi fruits when successfully pollinated, September Sun is primarily grown for its late-summer blooms and the decorative value of a hardy vine that survives harsh climates where tender kiwis would perish.

Seeds germinate at temperatures between 65 and 75 degrees Fahrenheit. Start indoors 6 to 8 weeks before your last frost date to give seedlings time to develop before transplanting outdoors.
Harden off seedlings gradually over 7 to 10 days before moving them outdoors. Plant after your last frost date when soil has warmed; spacing depends on your support structure, but allow at least 6 feet between vines to prevent crowding as they mature.
