‘Cliff Kidney’ is a waxy kidney shaped Potato with white flesh and white skin.

A delicious tasting early potato. It’s suitable for boiling, salads, casseroles and soups. Our beloved grandfather always grew this variety for the family Christmas feast every year.

Cliff Kidney has been grown in New Zealand since at least the early 1900’s. They are believed to have been commercially developed by a South Canterbury farmer come potato grower Mr H. E. M’Gowan, who stated that he was given the original tubers by Māori in 1902 from one of their old fortifications at Otago heads. It was there growing wild on the cliff, hence its name.

Early Crop: They are an early season potato that’s best enjoyed fresh and generally unsuitable for storing for long periods.

Harvest: About 80 – 90 days after planting. It rarely produces flowers but is harvested when any flowers are fully open and the foliage is still green.


Sowing Method: Sow Direct
Spring - Early Summer
Sow Direct

Seed potatoes are typically chitted in preparation of planting, which involves letting their roots start to sprout. To chit your seed potatoes spread them out in a light place but shielded from direct sunlight in a dry, cool, frost free area. Let the roots develop for about 3-6 weeks until they have reached 2cm in length. Our seed potatoes may have started to chit already and be starting to show root sprouts when you receive them.

Seed potatoes are best sown in spring through early summer. Northern areas can plant potatoes from mid winter, whereas southern areas should wait for frosts to have passed before planting.

Seed potatoes are best sown in rows directly in place approx. 25cm apart and 15cm deep, with rows spaced approx. 60cm apart. Sow your seed potatoes with their root sprouts pointing upwards and lightly cover with soil carefully as to not damage the formed sprouts.

7°c - 20°c 21 - 42 days

When your potato plants reach 5cm - 10cm in height begin mounding soil around the plants to protect potatoes from greening and insect damage, and continue mounding as they grow taller.

25cm - 30cm 80 - 90 days Tender


Potatoes grow best in well-draining sandy soils. Poorly draining soils are more likely to produced diseased potato tubers. Keep the soil moist and ensure your potato plants are kept free of weeds.

Trenching for your potato rows and only filling them in lightly at planting will allow you to use any leftover soil for mounding them up as your potato plants grow. As the stems start to push through cover them a little more each week until the mound has reached about 20cm in height above the soil. The more of the growing stem you have beneath the soil enables more opportunity for the plant to produce potatoes and a bigger crop.

Record your sowing/planting date and harvest once the potato plants have reached maturity according to the tips in the description above. Carefully dig out your potatoes with a fork or spade, and eat any potatoes that get speared first as they won’t keep for long. Once harvested store your potatoes in a cool, dark place to retain their freshness and eat and enjoy.

Botanical Name:

This is the formal scientific name for each plant, firstly identifying the genus and then the species to which it belongs.

The purpose of these Latin names is to have a single name that is accepted and used worldwide for a particular plant or plant group, and to help distinguish each plant uniquely from other plants.


This refers to the typical lifecycle of each plant.

Annual: Plants that complete their life cycle within 1 year (from germination to growing and producing seeds, then dying).

Biennial: Plants that complete their life cycle in 2 years (germinates and grows in the first year, then produces seeds and dies in the second year).

Perennial: Plants that have a life cycle of more than 2 years.

It is wise to consider the lifecycle of each plant before choosing its final growing position. For example, you may prefer to plant perennials away from annuals, so your perennials are not disturbed when your annuals are harvested at the end of their relatively short lifecycle.


This refers to the geographic region and approximate date of origin, as it is best known for each variety.

Please note that varieties listed as “pre 1900’s” are very old varieties that have often been grown for hundreds of years, and as such their specific dates of origin are hard to list accurately.

Best Sown:

This refers to when it is suggested the seeds are best sown, to encourage strong and vigorous growth in their ideal seasonal conditions.

Please note that while some varieties may be able to be sown outside the range suggested, they will generally perform best when sown in the approximate seasonal ranges provided.

Sowing Method:

This refers to the suggested method for sowing each variety. Using the appropriate sowing method will help to ensure you achieve best results.

Direct Sow: These are seeds that perform well when sown directly into your garden. These seeds normally produce fast growing and strong seedlings. Please note that young seedlings may still need some protection from harsh weather and pests.

Transplant: These are seeds that perform well when started in trays or containers and then transplanted to their final position once they’re a bit stronger. These seeds often produce slower growing and weaker seedlings that need some care and protection from weather and pests. Seedlings can typically be transplanted to their final position once they are large enough to handle (for example 5+cm tall with several true leaves).

Please note that for varieties where we list both methods you have the choice.

Soil Temp To Germinate:

This refers to the approximate soil temperature range for optimum germination of the seeds.

Please note that while some germination may occur outside these ranges, the seeds will typically germinate strongest when sown in the optimum soil temperature range provided.

Approx. Time To Germinate:

This refers to the approximate amount of time it takes for the seeds to germinate.

Please note that while some variation may occur, with ideal conditions this represents an average amount of time before germination. This relies in part on the seeds being sown in soil at an ideal temperature for germination, per the heading above.

Spacing For Seedlings:

This is the recommended spacing between plants in their final growing position.

Please note that spacing plants closer together than suggested will likely result in underperforming plants, due to crowding and over-competition for root space and available nutrients.

Approx. Time To Harvest:

This is the number of days until the plant typically reaches the purpose for which it is normally grown. For example, this is the time it takes for the plant to fruit or flower, or until the leaves are ready to be picked, etc.

Please note that while this refers to the beginning of harvesting time, the plants could keep growing for an extended period yet, particularly if kept well looked after.

Hardiness To Frosts:

This refers to how tolerant the plant is of frost and cold weather.

Tender: Plants that will be injured or killed by frost and cold weather. These plants will probably not survive winter.

Half-Hardy: Plants that will not tolerate severe frosts, but should otherwise survive winter.

Hardy: Plants that have the ability to survive frost and cold weather. These plants should survive winter.
