Delighted to see the first tamarillos emerging like jewels from these fast-growing trees. The leaves have been attracting aphids, but they seem responsive to strong sprays of water shooting them off. I’m not sure the occasional chili pepper garlic spray did much more than the water on its own.

I’ve also harvested my first few potatoes out of the strawberry patch. The strawberries, raspberries and blackberries are all still coming through strong. The blueberries are almost ripe, and the myrtus ugni are starting to form visibly behind the flowers. Feijoas are also fattening up even while still in bloom.

The area by the front door has filled up with fragrant star jasmine, which is apparently a seductive scent for cats as well as humans. At least for the the one below, who’s been hanging out on the front step a lot lately. When I approach to say hi, the cat scats. Directly across in the fernery, the nikau palm’s looking healthy, as are the native punga┬átree ferns.

There are also some mysterious mushrooms in the lettuce. Does anyone recognize these fungi? I appreciate your help in comments!

Halloween Special: Mummies in your Garden

Vivid tales of parasitic wasps eating mummified aphids from the inside out are but a part of this thought-provoking talk on plant protection using insects and the mass production of benevolent bugs.

A real horror story is that more than 90% of fruits and vegetables examined in NZFSA’s Food Residue Surveillance programme have pesticide residues. This method of natural pest control shown by Shimon Steinberg above could be a part of New Zealand’s strategy to reduce pesticide residues in our produce and soil.

Fancy fractal food: Broccoli Romanesco, Cauliflower Romanesco, or just Romanesco

Today, with great excitement, I harvested my first Romanesco and made a self-similar salad from it by breaking it into Romanesco-shaped pieces and tossing with a little olive oil and kelp granules. Perhaps the most delightfully geeky of all vegetables, the Romanesco is a nearly exact self-similar fractal form that illustrates a Fibonacci sequence. I have seen it in the marketplace as Cauliflower Romanesco and Broccoli Romanesco, and the French call it chou Romanesco, which translates to Cabbage Romanesco, so we’ll just note that it’s a Brassica and refer to it as Romanesco.

This electric chartreuse coloured vegetable offers a more subtle flavour than both cauliflower and broccoli, with a distinctively nutty note. I find it delicious raw, but it can be steamed or prepared in any way that you would with broccoli and cauliflower. And even though the organic ones often seem expensive at the market, I now know they are well worth it.

The Learning Curve

Romanescos at Yunos Farm stand at Abingdon Square Greenmarket, NYC I first became enchanted by Romanesco at the Yunos Farm stand at the Abingdon Square greenmarket in NYC (right), and noted if I ever grew my own vegetables, I would definitely grow this one. What I didn’t know is how much time, energy and water goes into each one. Because it’s always sold with the leaves stripped away, I assumed that the part we buy was the plant. Turns out it’s merely the flower of the plant. A giant plant. (This goes for broccoli and cauliflower too.) I thought I could tuck a few seedlings into the front of the berry patch, but they took over the space entirely for the season (image below).

The other growing surprise was that amidst an entire orchard, the Brassicas were voted most desirable plant by leaf-munchers and sap-suckers alike. I imagined the insects would go for dessert first, but they chose Romanesco, broccoli and brussels sprouts over berries and grape vines all day long. The most damaging was the hungry green caterpillar of the white cabbage butterfly. Eventually, I caved in and sprayed a trial of the bacteria Bacillus thuringensis Bt, which worked. Many of the plants bounced back entirely and produced beautiful veggies, while a few others never quite got their health back and suffered aphid infestation after the caterpillar menace subsided.

With broccoli, removing the central head stimulates side shoots for later picking. Does Romanesco work the same way? Let me know in comments if you do, and I’ll update when I find out here.

Update: According to Grow Better Veggies, “once the main head is cut, that’s it. You cannot rely on lateral growth for additional minor heads as the season goes on, which is a nice feature of regular broccoli.”

Companion Flower Salad

Flower salad: calendula, hyssop, nasturtium and borage Not only is Romanesco a flower that makes a great companion plant for other edibles in your garden (since everything wants to eat it), but many of the companion plants recommended for growing alongside it (and the rest of the Brassica family) are edible flowers too: (shown at left, clockwise from top right corner) Nasturtium, Hyssop “sweet marigold,” Borage, and Calendula. I don’t know if they distracted a single predator, but they definitely attracted bees, our friends in need, and kept any uninvited plants from crashing the party. They also add colour, beauty and diversity.

How do they taste? I found the Nasturtium too peppery for my palate, but it’s been brilliant in the garden as the earliest to bloom with bright orange blossoms. Borage, the last flower to arrive on the scene after a long period of leaf growth, features delicate blue flowers atop fuzzy stems that taste of cucumber. Hyssop ‘sweet marigold’ has an anise or licorice flavour. Calendula is slightly tangy and bitter and more appreciated for its use in topical tinctures and lotions than cuisine, but its leaves are lovely tossed into salads.
