The cucumbers will most likely be cross pollinating if they are close to each other; however, the results of cross-pollinating do not show up until the second generation of plants. This means that this years fruit will not be affected by cross pollination but the seeds inside the fruit will. Your cucumbers shape is just a coincidence.

To the plant, pollination is pollination. To the gardener who wants particular results (such as wanting to keep an heirloom variety pure), cross-pollination (cross-breeding) is something to avoid. To a grower or scientist who is trying to create a new variety, cross-pollination is desirable. It's all on your point of view. Like Dave said, some varieties are very genetically stable, like his Nantes carrots. Others, like curcubits, are notorious for cross-pollinating. If you're growing certain kinds of decorative gourds, and zucchini or other squashes, insects will cross-pollinate them very easily, and if you saved the seeds from your wonderful zucchini and planted them, they could end up being something almost unrecognizable and tasteless. "Does cross pollination always create a hybrid?" Yes and no. Technically, every pollinated plant is producing a hybrid, because every plant from every seed has a tiny, microscopic difference from the plant next to it, although it is, for most purposes, the same. Only cuttings, cloned or tissue-cultured plants are exactly the same as the parent stock. Plants labeled 'hybrids' have been crossed from plants with noticeably different qualities. If you crossed two of these 'hybrids', they would most likely revert back to the qualities of one or the other of the 'parents'. Granny Smith apples came from crabapples. If you planted a Granny Smith seed and nutured it for several years, you would probably end up with some sort of crabapple or similar variation. Two additional bits of info (just to confuse you a little more ;-) ): 1) You can be growing two similar plants near each other, but if they flower at different times, they won't (can't) cross-pollinate. Corn is a good example: there are early, mid-season and late varieties of corn. Corn cross-pollinates easily because it's wind-borne, but if they tassle (the 'flower') at different times and there is no other corn around (esp upwind), they won't cross. If Alfie's apples (above) needed a pollinator variety, and he accidentally planted a variety that bloomed a month after his Macintosh, he wouldn't get any apples. 2) OP varieties can be 'manipulated' even within the variety. You can have a packet of seed of a single variety of an OP plant, and each seed inside will have a tiny difference about it. Many people will grow a particular variety that they like, and they will watch for 'special' ones among that variety: a tiny bit earlier, a slightly larger fruit, a sweeter flavor, a slightly higher yield, etc, and they will mark it and let a few fruits of that plant mature and collect the seed. The next year, they plant that seed, and again look for 'special' plants. Every year, they keep doing this, and end up (hopefully) with localized variety within a named variety that is especially suited to their local conditions. It's still the same variety, it's still OP, it's just an improved variation within that variety. If you bought seeds from a grower in BC, and you bought the same variety from a grower in ON, the local seeds might produce plants that had a slight edge on local conditions, concerning earliness, adaptibility to hot summers, or ability to grow with a bit less water. The seeds from BC might adapt better to cooler summers, more humidity, and a longer season.

Hi! You should invest in the book 'Seed to Seed' by Suzanne Ashworth if you are thinking seriously about saving seeds( it's $15 on amazon). The book is the best in the genre, and gives you everything to know about saving the majority of seeds as well as their history. In the book it says that loofah squash will cross pollinate with other loofah squash (ditto cucumber), but, although they are in the same family, they will not cross with each other. I was wondering the same thing because I planted mine together, and my cucs seem bitter, but I suppose that's because they became dry a couple times (drought and business on my part). Good luck!

Hello everyone, I have a question about cross-pollinating melons, I have a bunch of different melons growing I've been thinking about cross-pollinating them to save the seeds for next year, I'm wondering what the different varieties of melons that can cross-pollinate with each other, I know Cantaloupe and Honeydew can, and Watermelons with each other, but that's as far as my knowledge goes lol the melons I currently have are Honeydew, Cantaloupe, Dino (Gaya) Melon, Moon and Stars Watermelon, and both mini and large Yellow Watermelon, any advice is greatly appreciated
