Seed of the Week: Pomegranate

Heather correctly recognized our aril-covered seeds last week as pomegranate, Punica granatum.

Pomegranates are originally from the Middle East. They grow wonderfully well in Arizona’s heat and alkaline soils.

In fact, some people grow them as landscape plants for their lovely red-orange flowers.

The plants readily produce fruit.

My son started our dwarf pomegranates from the seeds of a fruit. Ours only reach a few feet tall, but some varieties are large shrubs or even small trees up to 20 feet tall.

If you are not familiar with the pomegranate, you eat the fleshy part around the seeds. You can consume the seeds as well, or spit them out.

The fleshy part is called the aril, which is a botanical term for any outgrowth of the attachment point of the seed in the ovary.

In this video, you can see one way to handle separating the seeds from the white pithy material within the fruit.

Do pomegranates grow where you live? What is you favorite way to eat one?

Purdue has more information about pomegranates.

Weekend Science Fun: Spiders Into Space

Eeek, there are spiders everywhere this week. Here at Growing With Science, at Wild About Ants, and on the Space Shuttle Endeavor. What? Is that why it didn’t launch?

Okay, we’re just having a bit of fun. It turns out that spiders are going into space with the next launch (which will probably be after May 10, 2011) as part of a science project. Two spiders of the species Nephila clavipes will travel to the International Space Station where they will reside for 45 days. Video cameras will record their activity and allow children here on earth to learn more about spider biology in weightlessness.

The Spiders in Space mission is hosted at BioEd Online, where you can find updates and download a module guide (requires registration). The guide gives information about the spiders and the project. The idea is to set up a similar spider habitat here on earth to allow comparisons to spider behavior in space.

You have to find your own spider to put into it.

Note:  If you are not familiar with spiders, it might be a good idea to consult an expert as to what kinds of poisonous spiders might live in your region and what they look like, before you collect any. Here’s a photograph of a common type of orb weaver, which is the kind the video recommends.
