What’s Blooming: Tropical Hydrangea
by Kelly Kellow, Horticulturist, Gardens on Spring Creek

When the snow comes to The Gardens, outside plants are in their winter slumber. But, in the Butterfly House you can find plants that are in full bloom, making it a sweet, summer-like oasis.

There is one special specimen in the flight house that is blooming just in time to chase the winter chills away. Its giant, light pink spheres hang from the tree like shooting stars that smell like buttery cake batter – a true delight during the cold winter months!

Dombeya x walichii (DOM-bay-ya) or Tropical Hydrangea is in the Malvacea family and has large pendulous umbels of light pink flowers and large bright green leaves that have short hairs, giving them a velvety soft texture. It is native to East Africa and Madagascar and does not handle temperatures cooler than 30 degrees Fahrenheit, making it only suitable for tropical regions. It is perfect for our Butterfly House, with its high humidity and steady warm temperatures – much like what you would find in Florida or southern regions of the U.S.

Dombeya is a fast-growing tree or shrub and can add up to 36 inches of growth a season. On average, it grows to be 25 feet tall and 20 feet wide. When Dombeya starts flowering, butterflies will find the sweet-smelling large flowers very attractive. The flowers have a long bloom period and are important to the butterflies because they are rich in nectar during months when other plants are not blooming. Some plants bloom during the summer and will only grow vegetation during the winter. However, other plants, like Dombeya, bloom in the winter and grow during the summer. This is an important – and intentional – feature for our Butterfly House so that there are natural flower blooms all year round, in addition to the artificial nectar like rotting fruit, sugar-water cups and sponges we provide.

Every part of the Dombeya tree has some type of importance to the butterflies including the very large, bright green leaves that have been a lounging favorite. You can find them hanging upside down on the underside of the leaves or lying flat on top – a great plant for hiding, roosting and basking in the sun! Malachite, Mexican Blue Wing, Spicebush Swallowtail and Zebra Long Wings are some butterfly species that can be found lounging, feeding, and roosting all hours of the day on the tree. The Tropical Hydrangea tree is delightful for all visitors – whether walking or flying – during these cold winter months.

Monarchs and Marigolds in Día de Muertos Celebrations

By Angie Fuentes The Gardens on Spring Creek Community Engagement Assistant Monarchs Each year, right around Día de Muertos, millions of monarch butterflies arrive like clockwork to the misty mountains of central Mexico. Their appearance during this sacred time holds deep meaning for the communities of Michoacán and the State of Mexico, where the butterflies are seen as the returning souls of ancestors visiting the living. For generations, the Purépecha and Mazahua peoples, two Indigenous groups native to this region, have watched the skies fill with these migrating monarchs, their wings shimmering like a flowing river of orange and gold across the Sierra Madre hills. The butterflies’ arrival has been carefully observed since pre-Hispanic times, marking a spiritual moment when nature and the human spirit move in harmony. According to oral traditions, the spirits of the departed return on the butterflies’ delicate wings, joining their loved ones during Día de Muertos to celebra...

Blooming Blurb: Winter Interest, Native Plants Turning Red

By Kate Watson, Gardener As temperatures drop and summer blooms wilt, there are still many beautiful plants that can add winter interest to your garden. I am partial to the native species that bring warm red tones to a landscape. Here we’ll look at four plant species, native to Colorado, that turn red during winter and are found in The Gardens on Spring Creek. Creeping Oregon Grape Holly ( Berberis repens ) Creeping Oregon grape holly, Berberis repens (formerly Mahonia repens ), also known as creeping mahonia or barberry, is a low-growing evergreen shrub native to western and central North America. Often 1-3 feet tall and at least as wide, it has broad leathery leaves bordered by small spiny teeth, similar to holly leaves. While not a true holly, which refers to the Ilex genus, Berberis repens also forms berries. The berries are dark blue, resembling grapes, hence the common name “grape holly.” In winter the foliage turns red to dark purple when exposed to ...

Blooming Blurbs: Fall Edition

Blooming … Berries? By Ben Stickland, Seasonal Gardener By this time of year, many of us gardeners are already mourning the peak of summer when it felt like everything was vibrant and lush. Now, the warm colors of fall are taking over and most of our showiest bloomers are getting ready for winter. But if you peruse the garden on an October day, you will still see pops of color from a quintessential part of fall: fruits! This week, we are going to highlight some fruits that are taking over for the flowers and keeping the garden interesting and beautiful for autumn. Callicarpa dichotoma (beautyberry) The plant that inspired this article with just how beautiful its berries are (turns out they aren’t true berries), was the beautyberry. Callicarpa is a genus of plants native to many parts of the world, but this particular species comes from China, Korea and Japan. It is a compact shrub, typically growing 3-5 feet in height and spread, that has a slight weeping habit. It d...
