Planting & growing broccoli: it's that easy
There are many potato varieties, only a fraction of which are approved in Germany. Different varieties can be cultivated under a wide range of conditions and also have a variety of characteristics that distinguish them from other potato varieties. For example, they vary in size, harvest period, shelf life, taste or appearance. You can find an overview of the different potato varieties in this article.
Like the tomato, the potato plant belongs to the nightshade family(Solanaceae) and, like the entire plant family, originates from South America. Many varieties were originally native to the Andes.
The potato came to Europe in the 16th century with the discovery of America. However, it was not until the 19th century that it gained its status as one of the most important staple foods of Western civilization.
There are over 3,000 potato varieties worldwide, of which around 540 are approved in Germany (Sortenbundesamt, as of 2023). However, only very few potato varieties are still cultivated on a large scale. The varieties can differ greatly in shape, taste or harvest time.
Within these 500 varieties, around 395 potato varieties are table potatoes. The remaining 105 varieties are starch potatoes, which are used to feed animals.
Firstly, potato varieties are differentiated according to their cooking type , which is determined by their starch content. The more starch a potato contains, the more floury it becomes when cooked. A distinction is made here between waxy , predominantly waxy and floury potatoes. Firm-boiling potatoes include, for example, the popular Annabelle potato or the old Linda variety. Floury potato varieties include Hela, Bintje and Augusta.
Another distinguishing feature is the cultivation period. There are early varieties, which are also known as "early potatoes". These are usually ready for harvest at the beginning of June, as they only need just under three months to grow. Medium-early varieties need around 5 months and can be harvested from August. Late varieties, on the other hand, can be harvested until the end of October. Medium-early to late varieties are usually stored and can be eaten throughout the winter if stored correctly.
Depending on which dish is on the menu, you can use either waxy or floury potatoes:
Firm-boiling potatoes contain less starch than floury potatoes and are therefore firmer and easier to cut. They are popular potato varieties for potato salad, roast potatoes and jacket potatoes.
The more starch a potato contains, the looser it becomes when cooked. This is why floury potatoes fall apart much more than waxy potatoes. This is why you use floury potatoes for dishes such as dumplings, mashed potatoes or homemade gnocchi.
In addition to the cooking type, the ripening time also plays an important role for gardeners. The great advantage of early-maturing varieties is that they are harvested before late blight can occur. The risk of infection increases in summer and without plant protection, most medium to late-maturing potato varieties are affected and become infected. Here it is important to choose robust varieties, such as some old varieties. You can find a list of old, robust potato varieties further down in the article.
Unfortunately, early potatoes can only be stored to a limited extent and should be eaten within a few weeks. Late varieties, on the other hand, store well and will keep for several months if stored in the dark and at temperatures between 4 and 12 °C.
Early potatoes only need around 90 to 110 days to ripen. They quickly make room in the bed and are therefore a good pre-crop. They loosen the soil with their tubers and thus improve compacted soil. This improves the water balance in the soil and the soil structure. These varieties are usually not as productive as late potatoes. However, they are particularly aromatic and tasty.
The medium-early potato varieties are some of the most popular - they are particularly common in hobby gardens. They have an intense flavor and are suitable as storage potatoes. These varieties need around 120 to 140 days until they are ready to harvest.
These potato varieties produce the highest yields due to their long growing time. They stand in the bed for 140 to 160 days. The long shelf life of late potato varieties makes them an important part of the garden, especially for self-sufficient growers. When growing late potatoes, you should choose robust varieties.

Red or purple potatoes get their color from anthocyanins. This is a secondary plant substance that protects plants from excessive exposure to light. Excessive exposure to light produces free radicals (= oxidative stress) in the plant, which are bound by anthocyanins. Red potatoes are therefore particularly healthy, as they also bind harmful free radicals in the body and render them harmless.
Old varieties are becoming increasingly popular with buyers and gardeners. However, many old and traditional varieties have already fallen into oblivion. This is mainly due to the fact that they were not as productive as their competitors or were not suitable for industrial production due to their shape. However, important resistance to diseases and pests or flavor characteristics, among other things, were lost as a result of yield-increasing breeding. Old potato varieties are therefore increasingly coming into focus, as they could be used to breed new, unique-tasting and more resistant varieties. To read more about the diversity of old varieties, you can take a look at our article on the subject.
