Wildlife Wednesday: Gardening With Native Wildflowers

Wildlife Wednesday: Gardening With Native Wildflowers

By the time you sit down to read this, Spring wildflowers will already be in bloom. Blessed as we are with temperate short winters, we are also blessed with an early and long blooming season for wildflowers in the Houston area. This is important to a wide variety of pollinators, animals who feed on flower nectar and pass pollen between flowers.  It’s Important to resident animals to sustain themselves, and to migrants on their migratory journeys North. This not only happens in the wild, but is something we can contribute to, by planting and maintaining native wildflowers in pollinator gardens around our homes and businesses. With that in mind, lets have a look at a few species you can easily grow in the garden.

First, let’s define the terms discussed here. “Wildflowers” refers to plants that normally grow on their own out in nature, without needing our care, and not flowers whose current forms have been developed in the nursery industry. For our purposes, if a flower is generally unchanged from its wild form, even if bought at a nursery, we’ll call it a wildflower.

“Native” simply means that its from this region (ie. “Texas native”). Native, and generally unchanged in form (unlike some nursery trade cultivars) is important, because many of our native pollinators already know how to use and feed from native plants, and may not know how to navigate certain flowers from elsewhere. This renders some garden plants as pretty, but generally unhelpful to wildlife.

Indian Blanket (Gaillardia pulchella) aka Firewheel is a colorful relative of  daisies and sunflowers. Popular with bees and butterflies, these showy flowers bloom from late February through December. The long blooming period of this annual, hardiness, and wide appeal to a variety of pollinators make it perfect for home gardens. They only grow 1 – 2 ft tall.

Butterfly Gaura (Gaura lindheimeri), as the name would suggest, is popular with a number of butterfly species. They grow tall flower stems topped with delicate white and pink flowers. It goes well behind other shorter plants, and is tolerant of full sun and part shade. Guara blooms from April to November.

Lemon Beebalm (Monarda citriodora) and  (Monarda punctata) are both very popular with large bees and butterflies, and they are gorgeous complex flowers. Beebalms grow from April – July. They’re in the mint family, and have a history of medicinal use. They are perennials, coming back from root stock the next season.

Winecups (Callirhoe involcrata) are native ground creeping mallow (Hibiscus) that grows open shallow wine colored flowers that are appealing to a wide variety of bees, beetles, an smaller butterflies that may not be able to feed from some larger or deeper flowers. Each plant grows 8-12 inches tall and spread out to 3 feet. Its a perennial that grows through the Spring, and again in late summer and early fall.

March is a good time to get these plants in the ground, or plant seeds for flowers coming up in late Spring, Summer, and Fall. Check your locally owned nurseries for native plants, and check out the leftover plants from last weekend’s Bellaire Garden Club plant sale, still available in our back 40 area, at the Nature Discovery Center.

Also, call the Center for more details about upcoming nature hikes at 713.667.6550.

Thanks for joining us, and see you out in the park!

Wildlife Wednesday: Insect Friends in the Garden

Wildlife Wednesday: Insect Friends in the Garden

A couple of were working out in the herb garden behind the Nature Center building (the Henshaw House) a few days ago, digging in the soil and pulling out weeds, and we noticed several animals living or spending time in the garden as well. This week, we thought we’d give you a little survey of some of the creatures that are currently moving around the herbs.

Most people who grow Mexican Milkweed in their gardens expect Monarch Butterflies, and even the tiny yellow milkweed aphids, on their milkweed plants, but we were surprised to notice, a couple of years ago, that our herb garden milkweed had also attracted bright yellow and black Milkweed Leaf Beetles (Labidomera clivicollis). Like monarch caterpillars, these round conspicuous beetles feed on the poisonous leaves of the milkweed, and are therefore toxic to predators, as well. The beetles come on black and yellow, black and red, and black and orange.

There were a number of butterflies, but the 2 that were the most conspicuous were the Gulf Fritillary (Agraulis vanillae, above) and the Cloudless Sulphur (Phoebis sennae, right), as well as a few Monarchs. Gulf Fritillaries are not related to other fritillary butterflies, but are actually a kind of Heliconian, or longwing butterfly. The larvae feed on passion vines, and they keep emerging through the summer and fall in this area until low temperatures prevail. Cloudless Sulphur caterpillars feed on legumes, and both migrate here from the North and continue to emerge here into the Fall.

Eastern Leaf-footed Bugs (Leptoglossus phyllopus) are one of 3 common leaf-footed bugs that are found in our park throughout the year. We’ve seen the adults, and the red wingless nymphs prowling around plants in the garden. They feed on plants by piercing them with a straw-like proboscis and sucking juices out of the plant. The inject chemicals into the plants to aid in feeding, and these secretions may be somewhat toxic to the plant. In small amounts, this isn’t harmful, but in large numbers may kill the plant.They are harmless to people, but they may release a foul smelling substance when bothered.

Another small creature that we found all over the herb garden were Asian Many-spotted Ladybird Beetle (Harmonia axyridis) larvae. They of course look nothing like their red black spotted parents, but just like their parents, they are voracious predators, feeding mainly on aphids and other tiny plant sucking insects. They are a non-native invasive species, and negatively impact native ladybug populations. As with most ladybugs, they are toxic, and this is one of the few ladybugs (even as larvae) that may bite if handled.

Though the temperatures are dropping, its still possible to see some of these creatures in our gardens, and perhaps even in your own garden at home. If you get a chance some time soon, drop by and see what you can find.

Thanks for joining us this week, and see you soon!
