Seen any gray hairstreaks, lately?
No, not on someone's head.
This is the butterfly, Strymon melinus, from the Lycaenidae family, known as the gossamer-winged butterflies.
It's an ashy gray butterfly with a white border. You'll also see orange spots on the ends of its hindwings and one on its head, in between the eyes.
One's been hanging around our fava beans, and what a welcome sight.
UC Davis distinguished professor Art Shapiro of the Department of Evolution and Ecology says on his website:
"This is one of the most polyphagous butterflies known, recorded on host plants in many families. Its most frequent hosts in our area are mallows, including the weedy species of Malva; legumes, including Spanish Lotus (Lotus purshianus), Bird's-Foot Trefoil (Lotus corniculatus), White Clover (Trifolium repens) in lawns, Alfalfa (Medicago sativa) and many others;and Turkey Mullein (Eremocarpus or Croton setigerus, Euphorbiaceae)."
"Early spring specimens," he says, "are small and very dark with reduced red markings; 'albinos,' with the red replaced by pale yellow, occur mostly in the spring brood. There is much minor variation. Adults visit an immense variety of flowers, both wild and cultivated. They are particularly addicted to Heliotrope and white-flowered Apiaceae."
Sadly, Shapiro, who has been monitoring the butterfly populations of central California since 1972, has been seeing very few butterflies this spring in his transects. Let's hope the butterflies get back on track and give us a winning streak.

Every time we see honey bees pollinating fava bean blossoms, we think of actor Anthony Hopkins.
Remember that malevolent scene in the "Silence of the Lambs" film (1991) when serial killer Hannibal Lecter (portrayed magnificently by Hopkins (says: "A census taker once tried to test me. I ate his liver with some fava beans and a nice Chianti."
Film historians say most folks missed the significance "...Dr Lecter's choice of sides weren't based on his taste predilections, he was making a medical joke. Monoamine oxidase inhibitors (MAOIs) could have been used to treat him, and what are the three things you're not allowed to eat while taking them? Liver, beans and wine."
Fact is, some folks cannot eat fava beans because they have a disease called favism, a condition characterized by hemolytic anemia (breakup of red blood cells). It's linked to a metabolic disorder known as G6PDD (or Glucose-6-phosphate dehydrogenase deficiency). Indeed, some get an adverse reaction just by inhaling the pollen of the fava bean plant.
In the culinary world, the fava bean is commonly called the broad bean (Vicia faba) and is eaten raw or cooked. In the agricultural world, it's cultivated for human consumption and is also used for a cover crop to add nitrogen to the soil. Horses eat a variety called field bean.
But honey bees? They just can't get enough of them.

Fava beans, or broad beans, are one of the oldest know cultivated plants carbon dated to over 10,000 years ago according to research published in an online paper in the journal of Scientific Reports. They are a major crop in many countries, but not very popular in the United States – probably because it takes so much time to prepare them (LOL)!? But, believe me, the time and effort are worth it after you have tasted these delicate, buttery, nutty flavored beans.
The plant is like a pea plant. The pods can be harvested young and eaten whole or let them grow until they are big and bumpy, and then eat the bean inside the pod. The pod can be left on the plant until the both the pod and beans are dry.
Fava beans can be eaten raw, boiled, steamed, stewed, mashed, sautéed, fried, or roasted.
Freezing is a good way to preserve fava beans. Here is a step-by-step guide to harvesting and freezing fava beans.
Step 1. Harvest the beans. Look for large green pods that feel like there are little balls inside.

Step 2. Remove the beans from the pod.

After the beans are removed from the pods, you will have a beautiful bowl of shelled beans.

Step 3. Put the beans in a colander and rinse with cold running water.

Step 4. Now it's time to cook the beans and get them ready to freeze. For best quality, it's recommended to fully cook the beans. (There is no approved method for blanching fava beans before freezing.) Bring the water to a boil. Add some beans and bring back to a boil. You want to cook the beans in small batches to prevent over cooking. Cook each batch for about 4 minutes.

Step 5. Remove the beans from the boiling water with a slotted spoon and place in a bowl of ice water. Let the beans sit in the icy water for about 4 minutes to cool completely.

Step 6. Place the beans on a clean towel and dry. Put the dry beans in a single layer on a cookie sheet lined with parchment paper, nonstick foil, or waxed paper to prevent sticking. This method of freezing is called Individually Quick Frozen (IQF). It's a great way to freeze small sized foods and prevents them from freezing in a “clump”. Place the tray with the beans in the freezer for about 2 hours.
Speaking of “clump” – don't make the same mistake I did. I removed the outer layer of skin before layering the beans on the cookie sheet, froze them, placed them in a bag in the freezer and ended up with a wad of fava beans stuck together! Apparently, if the skin is removed, the bean remains moist and they will freeze together. I find leaving the skin on, also protects the bean from freezer burn and they have a fresher texture after thawing. Read more about when and how to remove the outer skin in Step 9.

Step 7. When the beans are frozen, place them in a freezer safe bag or container. If you have a vacuum sealer, now is a good time to use it. Label the container with the name and date they were frozen.

Step 8. The beans are frozen. Now what? When you are ready to eat some, remove the amount you want from the container. Place the beans in a bowl of lukewarm water.

Step 9. There is a layer of skin that needs to be removed. Yes, that is correct…another layer to be removed before you get to that yummy bean! Remember, I mentioned earlier not to remove the layer of skin until now? Put a small hole in the skin with your finger and pop the bean out. It's quick and easy!

Now you have a nice bunch of fava beans that are ready to eat.

Fava beans can be eaten cold (add them to a salad or munch on them as a snack). Or, they can be heated as a side dish, added into stew, fried rice, or used in a recipe in place of peas.
Here's my favorite recipe which is quick and easy. It takes less than five (5) minutes to cook.
Sautéed Fava Beans
1 c. fava beans, thawed and shelled (skin removed)
1 tbsp. olive oil
1 clove garlic, chopped
Salt and pepper, to taste
Fresh basil leaves, coarsely chopped
Heat olive oil in a pan. Add garlic and sauté just to soften, about a minute. Add beans, salt, and pepper. Continue sautéing until mixture is almost heated through. Top with basil, stir, and continue sautéing until basil is wilted and beans are completed heated.

This is a yummy side dish with lemon rice and crab cakes.

It's May and everything is growing beautifully, including weeds. Even if your garden is exceptionally well-weeded, new invaders will creep in and demand attention. Our general reaction is to remove them as soon as we realize that we have them, and we think of a good, tidy garden as one that is free of weeds.
In general, until you are comfortable with weed identification, keeping your garden entirely free of things that you did not plant is a good approach. However, weeds can also provide some benefits, so learning about the different weeds can help you decide whether you just might let certain ones grow for a while. Over time, you may make friends with certain weeds and make them part of the cycle of your garden.
So what is a weed? Most commonly we consider something a weed if it is growing somewhere we don't want it to. Those California poppies you love in your flower beds just might be a weed if they start growing in your vegetable bed. I was surprised to learn that some people consider miner's lettuce, an edible California native that I carefully cultivated in my garden, a weed.
How can weeds actually be beneficial? Some weeds are edible, many can supplement your compost, and some help loosen the soil. They may provide erosion control and dust control. Some provide food or habitat for pollinators and other wild animals.
In addition, weeds can teach us about our soil. Certain weeds prefer specific soil conditions, so if you have those weeds, you can assume that your soil has those characteristics.
Common edible weeds include purslane, dandelion, lamb's quarters, nettles, fennel and chickweed. If you're not sure what you're looking at (you only know it's not something you planted), you can use the weed identification tutorials and information on the University of California Integrated Pest Management (UC IPM) site. If you're going to eat weeds (the ultimate revenge), use common sense. Never eat anything if you're not totally certain you've identified it correctly.
Many weeds make good additions to your compost or can serve as mulch. Annual weeds that have not developed flowers can be chopped up and left in place, although in winter and in moist areas of your garden, you have to make sure they don't re-root. You can also chop them and add them to your compost bin.
Those parts of perennial weeds that won't re-sprout can also be added to compost or used as mulch. With perennial weeds, though, it's important to know how they propagate so you don't inadvertently spread a problem. If a perennial weed has not flowered, you can also let it dry out completely (think completely crispy and brown) and then put it into your compost.
Some weeds improve soil by growing deep roots that break up the subsoil (the layer immediately below the topsoil). That allows the weaker roots of more delicate plants to access the water and nutrients there. Some common weeds with deep, strong roots include wild chicory, plantain, sow thistle and vetch, as well as lamb's quarter and purslane. Cut these weeds off at the soil surface before they start to flower. The roots will decay in place, adding organic matter to your soil. The tops can go into your compost. You'll get the most benefit if you keep these weeds fairly far apart; if they grow close together their roots won't penetrate as deeply.
Some weeds are great for attracting pollinators. However, you have to let the weeds flower. The mustard we see flowering in Napa Valley vineyards is one example. Fennel, wild radish and pigweed are other examples of weeds that are good pollinator plants. Pull them as soon as they have bloomed, and do not put the spent flowers in your compost.
Weeds can also act as living mulch. This feature can be particularly helpful in winter, if you are not growing vegetables or an intentional crop such as fava beans. Almost any annual weed can serve as living mulch. (You do not want to give perennial weeds the benefit of extra growing time.) Some annual weeds, such as chickweed and purslane, will form a mat as they grow and thus help suppress other weeds.
Finally, weeds give you clues about what is going on with your soil. Like other plants, weeds have specific soil preferences. Chicory, purslane and lamb's quarters are generally good news because they indicate rich soils. Thistles, wild turnip and bindweed, on the other hand, can indicate that you have compacted soil or a crusted soil surface. Poor drainage can be indicated by weeds such as sedges and Bermuda grass.
Research your weeds and learn what they tell you about your garden. Whether as indicators, food or soil improvers, weeds can be garden helpers, too.

A Daily Practice
A Precious Gift
Two years ago, we received 10 fava beans from our dear friends. The seeds originated from the Sacred Valley region of Peru where they were hand-selected for a distinct spiral pattern on the seed coat. Starting with just a few seeds, we decided to grow this plant out in our urban garden in Midtown Santa Cruz. After successful plantings, I gently gathered these the dried pods of the newly formed fava beans.
Selecting Seed Adapted to Our Bioregion
The spicy mustard greens that generously fed us over the late winter and spring season have also since gone to seed. I harvested the seed heads and set them to dry on a large repurposed bed sheet. When fully dry, I will gently stomp on these seedpods, and sift them through fine screens to separate the seed from the chaff. The plants that did particularly well in our bioregion are the ones that we save. Over time, seed that is hand-selected in a place can become well adapted to the environmental conditions of that specific location. There are many features to save seed for, including taste, size, texture, color, drought resistance, disease resistance and overall health.
How I Save my Seeds
When dry and ready, you can begin storing your seed. Seed is well kept in a glass jar. Be sure to label each jar with the name of the plant, the date in which you collected the seed, and the location the seed was collected from. Keep in mind that seeds are living! It is best to store your seeds in a cool, dry, dark/shady space away from sunlight.
