Be a superhero! Plant flowers and save the world’s food supply

Okay.  Maybe that headline is a bit extreme…but it is not that far off.  Here’s why.

As we all have heard, bees seem to be vanishing all over the planet. And without them to pollinate edible plants–whether tomatoes in Pasadena or romaine in Yuma or pecans in the San Pedro river valley–we humans may be in trouble and face food shortages.

And it turns out that flowers can be part of the solution.

At a recent gardening event in Los Angeles a speaker recommended planting annual flowers between tomato plants to encourage more bees to pollinate the tomatoes while they are seeking nectar from the larger, flashier annual flowers. It helps keep the bees well fed and the bee colony thriving. Tomato plants will produce more abundantly, too.

“Wait a minute”, you say. “There are no commercial growers near me and I’m not growing vegetables in my backyard. Why should I encourage bees?”

The answer is that you can become part of a larger effort to sustain genetic diversity all over the planet.  That’s where the Gardener-Superhero role comes in.

As I look at many desert style gardens filled with agaves and other rarely flowering plants I realized that our new water-wise gardens are creating starvation conditions for our friends the bees. Not enough variety, not enough flowers blooming for not a long enough time.  Worse yet, in many desert areas, the native plants that could provide nectar to bees are being removed to make way for houses and roads.

It is, however, not necessary to plant water-guzzling plants to have bee-friendly flowers in a hot, dry garden.  Here are some that will thrive and  produce flowers over a long period without running up your water bill.

Low-growing Lantana (Lantana montevidensis)  is one of the best and most readily available flowering plants for hot, dry gardens. Bees and butterflies love it! It blooms for as long as 9 or 10 months out of the year and because it is a perennial, rather than an annual, you will not have to replace it every year. Be aware that the purple and white varieties bloom for a much shorter time than the gold, yellow or varigated Lantanas. Upkeep is easy: in mid-winter cut the low-growing branches back to a foot or so in length.

Instead of the low-growing lantana, however, consider planting Lantana camera.  It grows to 6 feet tall and makes a very colorful, bee-friendly hedge. A light mid-winter trimming is all the maintenance needed.

Next, Rosemary (Rosemarinus officinalis) attracts bees like a magnet and can provide a delicious herb for your table. Plant several about 2 feet apart to create a rosemary hedge or simply put one plant outside near your back door to clip and use the aromatic leaves in bread or for baking chicken.

Lavender (Lavendula) is another tasty and aromatic herb that bees love as much as humans do.  I prefer French lavender to the English or Spanish varieties, but I have to confess that I have not had much success keeping lavender plants alive from year to year. I simply replant annually.

And finally: annual sunflowers.  If you plant the seeds over a period of a couple of weeks, you will have a longer blooming period for the bees to harvest the nectar. Then later, birds will come to harvest the seeds. You can harvest them, too, and then toast the seeds in your oven for a tasty snack.

So get out your garden gloves and think of them as the red superhero cape for gardeners.
