How can you tell if a cucumber is parthenocarpic?
Parthenocarpic varieties can be identified by the greenhouse symbol in our catalog and on our website. Some cucumber varieties are both gynoecious and parthenocarpic. They characteristically produce the high yields of all-female flowers without the need for pollenizer plants.

Are all cucumbers self-pollinating?
Most cucumber varieties are monoecious with unisexual flowers—have separate male and female flowers within the same individual— and thus require animal pollination for reproduction. However, some varieties are mostly or totally gynoecious (produce only female flowers) and can produce fruit through parthenocarpy.
Are Japanese cucumbers Gynoecious?
Some of the Asian type cucumbers are parthenocarpic that are well adapted to greenhouse/high tunnel production, however, the majority of this type of cucumber plants is monoecious producing both male and female flowers.
Are Persian cucumbers parthenocarpic?
Yet another common characteristic of some Persian cucumber varieties is that they are parthenocarpic. This means they can produce fruit without need for pollination.
Do F1 cucumbers need pollination?
These plants don’t need pollinating – in fact, you should remove any male flowers to prevent pollination happening or the fruits will end up bitter. You can buy all-female F1 hybrid varieties, such as Cucumber ‘Bella’, so that this won’t be an issue.
Is Japanese cucumber self-pollinating?
The yellow, star-shaped flowers are easy to tell apart by looking at their stem. Female flower stems have a small lump that becomes the cucumber fruit after pollination. Like most modern varieties, Japanese cucumbers are self-pollinating.
How do cucumbers pollinate without bees?
You also can remove male flowers and touch the anther (in the center of the male flower) to the female flower’s stigma (also in the center), or shake the male over the female, to transfer the pollen. Hand-pollination can help you have a great harvest of cucumbers, melons, pumpkins, and squash.
Do lemon cucumbers self pollinate?

Why do my cucumbers have flowers but no cucumbers?
A cucumber plant will flower but produce no fruit if there is a lack of either male or female flowers on the plant. A lack of fruit will also occur due to poor pollination. Growing conditions (such as temperature, weather, and nitrogen levels) also affect pollination and flower production.
Why are my cucumbers flowering but not fruiting?
The female flower cannot produce the pollen needed to cause the fruit to develop and is dependent upon insect (or human) pollinators to transport the pollen from the male flower. The male flowers begin forming before the female flowers form. So, it is possible to have cucumbers blooming, but not producing fruit.
