Datura’s morning glow


The datura (Datura wrightii) I planted in the front garden a few years ago has petered out and needs replacing. But this volunteer that self-seeded in the back garden is growing beautifully. Moreover, it asks nothing from me except an occasional pinching back of stems that threaten to overpower nearby plants.


Almost every evening it unfurls white, fragrant trumpets that glow all night and into the next morning.


Such a heady fragrance! And aren’t the spurs on the folded-linen flowers interesting?


A beauty, but all parts are deadly if ingested, so be cautious about planting it if you have pets or children that like to graze.

Silver ironweed in bloom


Unirrigated and thriving in decomposed granite, West Texas native silver ironweed (Vernonia lindheimeri var. leucophylla) powers through the depths of summer. I enjoy its silver sheen and purple pom-pom blossoms and its Texas-tough attitude.

For more info, click the link above, which will take you to a newsy page I wrote about this plant a few years ago.

Plant This: Pale pavonia, or Brazilian rock rose


Even in gentler months, my shady garden is not particularly flowery, and in the heat of summer those perennials that do flower — salvias, mistflowers, cupheas — tend to hunker down until fall. One happy exception is pale pavonia, also known as Brazilian rock rose (Pavonia hastata), a cousin to our native hot-pink rock rose (Pavonia lasiopetala). Its tissuey, hibiscus-like white flowers with wine-red eyes and veins bloom all summer on rangy stems of narrow, toothy leaves.


Impervious (in my garden, anyway) to deer, it handles the dry shade of live oaks with aplomb. In the island bed in the driveway, I’ve paired it with our native palmetto (Sabal minor), ‘Sparkler’ sedge, and foxtail fern (Asparagus meyeri). There’s also a burgundy-leaved loropetalum in the mix, which I think will look great with the pale pavonia’s red eyes, if it would only grow.


In the side garden, I replaced my original low hedge of flame acanthus, which was continually browsed by deer, with pale pavonia, which blooms reliably amid bamboo muhly (Muhlenbergia dumosa), inland sea oats (Chasmanthium latifolium), and a Mediterranean fan palm (Chamaerops humilis) on the right. (And if you’re curious about the blue tree behind the fence, that’s a ‘Blue Ice’ Arizona cypress, one of my favorite trees for that icy-blue color, pyramidal shape, and a Christmasy fragrance.)


Pale pavonia tends to seed out in the garden, but I find its seedlings easy to pull up after a rain, or you can transplant them around your garden. It can be a little cold tender, so I recommend planting it in spring, not fall. Dave’s Garden says it’s hardy to zone 7a, which I’m a little dubious about, but maybe in a warm microclimate. It grows to about 4 feet tall and wide in my garden, with a rangy appearance, kind of like Turk’s cap.


As MSS of Zanthan Gardens noted in a long-ago but useful blog post (she first inspired me to try pale pavonia 10 years ago), some of the flowers in spring and early summer are cleistogamous — i.e., they produce seeds without opening — so you may watch expectantly, awaiting a flush of flowers, only to be disappointed. Be patient. The glowing white flowers will light up the shade by midsummer through fall.

Note: My Plant This posts are written primarily for gardeners in central Texas. The plants I recommend are ones I’ve grown myself and have direct experience with. I wish I could provide more information about how these plants might perform in other parts of the country, but gardening knowledge is local. Consider checking your local online gardening forums to see if a particular plant might work in your region.
