As gardeners around the country are encouraged to plant more asclepias to encourage monarch butterflies, many folks are finding out that not all species of asclepias make good garden plants. As a genus, asclepias consists of running and clump forming species. There are number of horribly weedy garden plants like Asclepias speciosa, Asclepias syriaca, and Asclepias fasicularis. These plants are fine in a prairie garden, but are disastrous in more controlled home gardens.
One of our favorite clumping species is the easy-to-grow, Arizona-native Asclepias angustifolia ‘Sonoita’. This superb species was shared by plantsman Patrick McMillan. It has proven to be an amazing garden specimen, thriving for years, despite our heat and humidity. Did I mention it flowers from spring through summer?
This is the time of year when the tiger swallowtails feast on our many patches of the amazing native Stokes aster. Our favorite clone is the upright growing Stokesia laevis ‘Peachie’s Pick’. Moist soils are best, but stokesia tolerates some dry conditions on a short term basis as long as it has 2-6 hours of sun.
One of the little-known native asclepias, milkweed, is flowering in the garden this week. Asclepias variegata, redwing milkweed, is a widespread native, ranging from Canada and Virginia south to Florida, and west to Texas. So, why is this virtually unavailable commercially? Our plants typically range from 1.5′ to 2′ tall, although 3′ is possible. For us, it performs best in part sun to light shade.
The specific epithet “variegata” which refers to two colors on the flower was certainly a poor choice, since most asclepias have multi-color flowers. Of course, Linnaeus didn’t have the benefit of the internet back in 1753.
The Pipevine Swallowtail butterfly caterpillars are munching away on any aristolochia (pipevine) in sight. This week, their favorite in the garden is the stunning Aristolochia fimbriata. Nature has created a wonderful balance where the catepillars each just enough to survive and grow, but not enough to damage the plant, which will quickly re-flush.
Hurricane Hermine brought some much needed rain over the weekend. Not only were there some happy gardeners, but the rain lilies are loving it too. Here is a picture of Zephyranthes ‘Heart Throb’ in the garden with its bright 2″ reddish-pink flowers and contrasting white eye. At a mere 6″ this Heart Throb is a real show-stopper.
Rain lilies got their common name from their charming habit of producing new blooms after it rains. Rain lilies come in a variety of colors to coordinate with your garden’s palette. Plant rain lilies near the garden path where you can enjoy their beauty from mid summer up until fall. Be sure to come check out our wide selection of rain lilies this coming weekend, Sept. 9-11, during our fall open house, and you can take home your very own Heart Throb!

Lobelia cardinalis is native to 41 out of the 50 states in North America. The cardinal flower is tolerant of many different soils from moist bogs to average garden soils, and is perfect for use in rain gardens. Cardinal flowers are also a magnet for hummingbirds and butterflies. Lobelia begins blooming in summer and will continue until fall with an array of flower and foliage colors to blend nicely in your garden, from the brilliant red flowers of the species, to the hot pink Monet Moment, or the burgundy foliage of Black Truffle.
You can order cardinal flowers online or visit us at our fall open house September 9-11 & 16-18 to see the cardinal flowers blooming in the garden and pick out that perfect plant for a spot in your garden.
