Milkweed




Like many gardeners, I grow milkweed because I think it is pretty but mainly for the butterflies. Butterflies of many kinds enjoy sipping from its flowers, but butterflies like the Monarch and the Queen are completely dependent upon it for the nurturing of their larvae. 

 As we know, the Monarch in particular has been declining in recent years and one of the reasons has been the destruction of milkweed plants by industrial and agricultural development along its migration route across the continent.


Throughout the year, the Monarchs flit through my garden and many of them lay their eggs on the milkweed plants there.

And soon I find their caterpillars happily munching their way through the leaves of the plants. A heavy crop of caterpillars can completely strip the leaves from a plant in a few days. Through our long growing season, an individual plant may regrow its leaves several times.

Nearing the end of the season, the plants develop their feathery seeds which will be spread by the wind if the gardener doesn't remove them. The result can be "volunteer" milkweed sprouts in unlikely, unexpected places around the garden.

 Also, as the season advances, the plants are host to many different insects like the milkweed bug in the above picture. As the plant declines, they signal their vulnerability to the insect world and become prey to more sinister leaf chompers and suckers.

The most destructive of these, from my point of view, are the aphids. A crop of these can really uglify a plant in short order.

 I would prune off the affected limbs along with their squatters except for one thing: Where there are aphids, there are ladybugs on the job.
  

Ladybugs love aphids! Over a few days, they will completely scour a plant of them. Then will be the time to cut the plant back and let it regenerate.
  
Even more voracious devourers of the aphids than the adult ladybugs are their larvae, like this little guy. It takes a lot of aphids to transform this into an adult ladybug and that's good news for the gardener.


 Also aiding in the fight against bad bugs are spiders like this tiny jumping spider.  

 By this time of year, the milkweed plants that were so pristine and pretty in the spring have become an eyesore in the garden. But they are still providing important habitat and food for many insects, arthropods, amphibians, and reptiles. Gardeners who understand this can easily tolerate the ugliness for a while. When the aphids are gone, the plants can be cut back and, at least here in zone 9a, they will regenerate and probably be in flower again before the end of the year. 


Ready to sustain and nurture more generations of Monarchs and Queens.

    It's a beautiful thing to know that the monarchs feeding on my zinnias today will be nourished in your garden just a few days from now - maybe. Because our unseasonably warm sum...I mean, fall, continues!

    Your story of the milkweed is like a novel where one of the characters has many sides and appears in many ways. I wonder if I could tolerate all the changes the plant goes through in a season. I do love butterflies and lady bugs, I do fear the aphid. Perhaps I will give the valiant milkweed a try. I can always come back and read your post if I have any difficulties!

      It is a valiant and adaptable "weed". Mine is the tropical milkweed and it gets tall and rangy and unlovely if allowed to grow freely all year long, but one can cut it back repeatedly during the season to keep it bushy if that's what you want. I'll be cutting most of mine back soon so that it can regrow and keep providing nourishment for the butterflies.

Poetry Sunday: Don't Hesitate by Mary Oliver

How about we share another Mary Oliver poem? After all, you can never have too many of those. In this one, the poet seems to acknowledge that it is often hard to simply live in and enjoy the moment, perhaps because we are afraid it can't last. She urges us to give in to that moment and fully experience the joy. Although "much can never be redeemed, still, life has some possibility left." Don't Hesitate by Mary Oliver If you suddenly and unexpectedly feel joy, don’t hesitate. Give in to it. There are plenty of lives and whole towns destroyed or about to be. We are not wise, and not very often kind. And much can never be redeemed. Still, life has some possibility left. Perhaps this is its way of fighting back, that sometimes something happens better than all the riches or power in the world. It could be anything, but very likely you notice it in the instant when love begins. Anyway, that’s often the case. Anyway, whatever it is, don’t be afraid of its plenty. Joy is no...

Poetry Sunday: Blackberry-Picking by Seamus Heaney

My mother was a farm wife and a prodigious canner. She canned fruit and vegetables from the garden, even occasionally meat. But the best thing that she canned, in my opinion, was blackberry jam. Even as I type those words my mouth waters!  Of course, before she could make that jam, somebody had to pick the blackberries. And that somebody was quite often named Dorothy. I think Seamus Heaney might have spent some time among the briars plucking those delicious black fruits as well, so he would have known that "Once off the bush the fruit fermented, the sweet flesh would turn sour." They don't keep; you have to get that jam made in a hurry! Blackberry-Picking by Seamus Heaney Late August, given heavy rain and sun For a full week, the blackberries would ripen. At first, just one, a glossy purple clot Among others, red, green, hard as a knot. You ate that first one and its flesh was sweet Like thickened wine: summer's blood was in it Leaving stains upon the tongue and lust ...

Poetry Sunday: Hymn for the Hurting by Amanda Gorman

You probably remember poet Amanda Gorman from her appearance at the inauguration of President Biden. She read her poem "The Hill We Climb" on that occasion. After the senseless slaughter in Uvalde this week, she was inspired to write another poem which was published in The New York Times. It seemed perfect for the occasion and so I stole it in order to feature it here, just in case you didn't get a chance to read it in the Times . Hymn for the Hurting by Amanda Gorman Everything hurts, Our hearts shadowed and strange, Minds made muddied and mute. We carry tragedy, terrifying and true. And yet none of it is new; We knew it as home, As horror, As heritage. Even our children Cannot be children, Cannot be. Everything hurts. It’s a hard time to be alive, And even harder to stay that way. We’re burdened to live out these days, While at the same time, blessed to outlive them. This alarm is how we know We must be altered — That we must differ or die, That we must triumph or try. ...
