This was an excellent corn for growing in containers. The plants reached heights of just over 3 feet and yielded between 3 to 6 ears per plant. It is one of the sweetest heirloom corns available.

I noticed a comment from 2009 where they stated "it was bland and not sweet". Sounds like you most likely let it get too old before you harvested it to eat. This is an easy mistake to make with this plant, and probably the most common mistake. The corn becomes harder and the sugar content drops rapidly as it nears full maturity, at which point it is good for seed, but not eating.

I continue growing this variety year after year, and it keeps performing the same. It's a great corn for those with limited amounts of space, but if you have the room, I would highly recommen... read more

The 'Blue Jade' is mine and my family's favorite corn so far. It's not a super sweet hybrid corn, but an old OP with a good, classic sweet corn flavor. The color is absolutely gorgeous and holds up with cooking. This corn is also good for freezing and adds nice color to a dish when mixed with yellow or white corn.

Plants top out at around three feet tall with several small ears per plant. Corn is white and still tasty when immature ripening to steel blue. Color does not come to full intensity until the ear's husk begins to yellow.

This is a unique, fairly fast maturing, trouble free variety that is perfect for cool summer climates that are less adapted to growing long season corn.

I was very excited to find a miniture corn that could be grown in containers and the fact that it was such a striking color was an incredible bonus. (I'm always looking for odd or unusual vegetables.)

I eagerly harvested the first ears for a family get together. Everyone who tried it agreed: The texture was dry and the taste bland and not at all sweet. In the end, I tossed every single ear I harvested into the yard for the squirrels.

Miniature plants bear 3-6 ears of sweet, steel-blue cobs that turn jade-blue when boiled. Plants grow 2-3' tall. One of the only sweet corns that can grow in containers.

Information only, I have not grown this variety.

Very small plants bear 3 to 6 ears. The steel blue cobs are supposedly sweet and tasty for an older variety of sweet corn. The cobs turn a lighter shade of blue when boiled.

This sweet corn can be grown in containers, so is an option for those with limited space, or apartment dwellers.
