I like to experiment with the store-bought seeds. This year I put a few honeydew seeds into the soil where it is watered by my lawn sprinkles. It grows very well but doesn’t set fruit readily. I think it is because of the very hot weather. The big one you see on a photo was set during the coolest period we had this summer.
I think I need to build a cage around it, the raccoons are waiting around the corner for sure :(

What other seeds from a grocery store you tried that can grow easily?

Enjoy!

 

The garden center I work at sells pumpkins, squash, and gourds in the fall. Rotten ones get chucked out on the compost pile. So far this year I've picked at least 3 bushels of small decorative gourds and acorn squash from the seedlings. Plenty of pumpkins grew, but groundhogs ate them all.

We have grown Ambrosia melons a few years. Sometimes they are excellent and very flavor full sometimes not.

I've kinda given up on them since we can get really outstanding melons from a big fruit market nearby Corrado's

We recently had a Honeydew that was orange on the inside fromFisher Ranch in Blythe Ca that was outstanding

I have grown Korean Melons the last two years and have harvested about a dozen last year on eight plants and should pick as many this year off of five plants. They are delicious. If anyone would like to try growing these melons seeds are available from Johnny's Seeds in Maine or you can find the melons in any Korean market in the summer time. These are pictures of the first ones I picked this year.

Igor, I put some passion fruit seeds from the store in a pot. Out of some 10 or so, only one survived, and it is growing beautifully.  I also grow amazing strawberries from seeds of store bought ones. they are large and fruit longer. I am getting another harvest from my plants.  Grapes and tomatoes also. I like  to experiment as well.
lawn? Well that is a waste of water. California is going to run out of it..should not waste on grass that nobody can eat.

Igor, the only bad thing about using seeds from store bought melons is that they're usually hybrids that produce good melons but their next generation doesn't breed true.  In general, the seeds from these hybrids do not produce good melons.  If you get heirlooms it's a different story.  As long as you pollinate a certain heirloom with itself you'll get the same heirloom from the seeds.

Interesting, Bob. So far, mine looks like the mother melon. I hope the taste would be the same. Does it mean it is not a hybrid? 
Who knows..

Grasa, I also tried the strawberries but not the large ones but the Alpine little strawberries. They grow and produce very well all year around small very fragrant berries. I have them for two years now and love them. I think from the seed to the berry it took me about 5-6 months.
The lawn thing is a totally different question. It keeps the air temp about 10 degrees cooler every summer day so our AC runs not as hard and you actually can be outside. Yes, it is a waste of water on some level and I wouldn’t mind to stop watering the grass but the SoCal summer can be hellishly hot. Also, my lawn is not that big. I have many large trees that do not allow the sun to go through for the grass to grow.

swizzle, I should try the ethnic stores too, they sell many interesting varieties. Your Korean Melons look like the ones to get!

Rich, yes, the store bought melons are very good but the curiosity has won the battle and the barren patch is green now! 
The same with nectarines, they are cheap and tasty in the season. I took a few largest seeds, put them in a fridge for a several months and they germinated in the spring 2 years ago. No fruit yet but the tree I left to grow looks beautiful and provides some shade for my figs :)
