Native Plant Week

This week is Native Plant Week. Check out the Lady Bird Johnson Wildflower Center site and bookmark on your computer the NPIN: Native Plant Database. You can type in any native plant in North America (common name or botanical name) and you’ll be taken to a page with photos and information about that plant. It’s a valuable resource for any gardener interested in Texas native plants or native plants anywhere in North America. If you live in or near Austin–visit the gardens! Join and become a member. If you travel to Austin from elsewhere and you have even minimal interest in gardening, the Wildflower Center is a must see.

October is also “Support Your Independent Nursery” month. Check out my list of great local nurseries on the Garden reference page and then follow the links below to these excellent blogs for more information about a nursery prize contest. And then, purchase and plant some natives for your garden!

Birds Love ‘Em, Bees Love ‘Em

Posted on October 15, 2011 by Tina

Bees love ’em.

Butterflies love ’em.

Hummingbirds really love ’em. Unfortunately, I’m not a good enough photographer to catch a hummingbird feeding. You’ll just have to take my word for it!

I love ’em too. Turk’s Cap, (Malvaviscus arboreus var. drummondii), is one of the first native plants that I fell in love with many years ago. Turk’s Cap is a deciduous perennial that thrives in just about any situation. It’s a staple in the shady garden, but also does well in full sun. It can handle severe drought, but doesn’t rot when we endure occasional floods. An excellent nectar source (for the above mentioned critters) it also produces a fruit that birds and little mammals love. (Some might take an exception to my inclusion of squirrels as desirable wildlife, but they are wild, and they are life and they do live amongst us.) Turk’s Cap also does well in a variety of soil types. Aside from the difficult soils that we have in Central Texas, I have also seen these plants growing in sandy Texas coastal areas and they do well there too, with the exception that they will dry out more rapidly. But in Central Texas, one can’t have a more reliable plant in the garden.

Turk’s Cap has a small, bright red bloom that looks like a tiny hibiscus which never quite got around to opening up.

Like hibiscus, Turk’s Cap is in the Mallow family, so the similarity makes sense. The petals swirl around the stamen, which protrudes upwards and outwards from the center. The leaves are palm-shaped and tropical looking (again, that Mallow thing). In the Austin area, Turk’s Cap bloom from May until November–a wonderfully long and prolific bloom cycle! They bloom well in full sun, shade and anything in between.

I believe that Turk’s Cap is classified as a shrub, but I always think of it as a herbaceous perennial. The plant grows from the base at the soil line in long stems. As the plant grows taller and the roots colonize outwards, Turk’s Cap take on the appearance of a large shrub, especially In established plants (more than 3 years old).

Several of my Turk’s Cap shrubs are easily 12-15 feet in diameter–they are also 10-15 years old. In normal years, they reach 5-6 feet in height. In wet years (gosh, do I remember those??), Turk’s Cap require pruning to keep the long stems from flopping over. Because of the drought this year, all of my Turk’s Cap are a little shorter in height than normal.

I mentioned in my post about Goldeneye that the Turk’s Cap behind a stand of Goldeneye (above photo) in my front garden should be taller, but was dwarfed by the drought. For that particular plant, I only water when I can remember or when it looks sad. It also receives afternoon sun. Perhaps if I’d watered a bit more, it would be closer to its normal height.

The extreme heat this year didn’t seem to have any negative effect on the blooms or the appearance of leaves in any Turk’s Cap that I’ve grown–unlike some plants which developed sun burn.

Once our nights begin to cool (whew!!) and the sun is less harsh, Turk’s Cap bloom less and some of the leaves will turn yellow. Turk’s Cap are definitely summer superstars and are not necessarily the most attractive fall plant. They will continue to bloom minimally and they produce fruits, so they remain an excellent wildlife food source well into the fall and even winter months.

The fruits are about 1/2 inch in diameter and are green, then turn red. Both are visible in this photo:

When we get a hard freeze, the plant’s leaves will drop and the stems die. For most of this past decade, my Turk’s Caps have remained at least partially green through most of the winter. During some winters, the whole plant remained green-stems and leaves. Because we experienced some very hard freezes in the winters of 2010 and 2011, almost all of mine died to the ground. Regardless of how the winter temperatures affect Turk’s Cap, I prune the stems to the ground in late January/early February because I get tired of looking at sticks.

Every Texas gardener, especially those in Central Texas, should include Turk’s Cap as a part of the the palette of plants in their garden.

Darn Birds

Posted on October 12, 2011 by Tina

This is a photo of my American Beautyberrry (Callicarpa americana).

Sans berries. The birds, mostly mockingbirds and a few bluejays, ate them. All of them. Within two weeks of the berries turning the signature outrageous purple, the birds ate every last berry. I’m not a happy Beautyberry gardener. Never mind that I planted the Beautyberry to attract birds to my garden–surely they could let me enjoy the berries for a while? This native-to-the-southeastern-part-of-the-United States plant (including Texas), is a large, deciduous shrub. In August/September it showcases gorgeous purple (sometimes white) fruits or berries.

The arching stems bear the beautiful berries in multiple clusters. Until those darn birds eat them.

These photos are of an unmolested Beautyberry at Howson Library Garden.

I don’t know how the many birds that love those berries have managed to miss this shrub, but they have, at least so far. Some years, I have been able to enjoy the berries on my Beautyberry (just looking, not eating!) well into the winter, even after leaf-drop. In dry years, my berries disappear shortly after they turn color. I assume with the drought this year, the birds are eating what they can, as soon as they can.

This is a large shrub, so it’s best to give it room to spread. I’ve never pruned any that I’ve gardened, but they can be pruned to the ground if you want them to be more compact. Beautyberry shrubs work well as single specimens or, if you have the space, in a colony–they’re quite striking when planted two or three together. In my personal garden, I only have the one shrub, in dappled shade with some very late west sun. They do well in full sun too, with a little extra water. The tiny, delicate, pink blooms occur in June and the clusters of green, then purple, berries develop over the summer months. Without the berries, Beautyberry is a somewhat nondescript shrub. But it is graceful, open and airy, with attractive arching branches and sometimes, the leaves turn a nice yellow before they drop. After the darn birds and the first hard freeze, the shrub is barren until spring.

In Shay’s Green Garden at Zilker Botanical Gardens there are two Beautyberry shrubs with white berries. I prefer the purple berries, because the purple is so…bodacious, but the white berries are lovely too. In that particular garden, I added some White Mistflower (Ageratina havanensis), and some white Tropical Sage (Salvia coccinea) and last fall, the combination was very nice–elegant in fact. This year, the darn birds and the squirrels, ate the berries immediately, so the garden is not quite so dramatic. Oh, well. That’s what happens when you plant native plants that are here for the wildlife. They chow down.

And that’s the way it’s supposed to be.
