Romanesco Broccoli and the Fibonacci fractal

Romanesco Broccoli is a variety of the species Brassica oleracea. It is a cool weather crop that enjoys a steady diet of nutrients. We fertilized with fish emulsion every other week.

The beauty of Romanesco lies in its unique flower structure. When we consume Romanesco, other than the stems we are eating flower buds.

These flower buds are very well known in science circles for being a natural example of the Fibonacci fractal. In mathamatics a Fibonacci fractal will go on forever, ad infinitum. A broccoli plant obviously does not go on forever, but the pattern does repeats itself in every bud.

This article explains it well, Fibonacci-Shaped Romanesco Broccoli Is the World’s Most Visually Stunning Vegetable

See other natural fractals in this Wired gallery.

Other than being really healthy for you, Romanesco broccoli is a cool way to bring math into the classroom.

Here’s one place to purchase seeds, Baker Creek Heirloom Seeds.

Potting up

When starting seeds indoors it is sometimes necessary to repot new seedlings into a bigger container rather than plant them immediately outdoors. We call this practice potting up. In the enclosed video I am potting up Broccoli into a peat pot which can then be transplanted at later date directly into the soil.

Week 19 – Pop Quiz

When we eat broccoli do you know what part of the plant we are eating? I’ll give you a hint, it’s the same part of the plant as when we eat artichokes. Here’s another hint, when we don’t pick broccoli in a timely manner this is what it looks like-
We are currently harvesting broccoli, carrots, peas, spinach, swiss chard, lettuce and radishes. Identify what part of the plant we are eating for each vegetable. First entry with all correct answers wins a packet of seeds.

Happy New Year

I’m sure glad students will be returning next week. Peas are getting plump, broccoli heads are blossom tight, carrots are starting to push their shoulders from the ground and our lettuce patch needs thinning, not to mention all the weeding that needs to be done!
