What's Blooming: Theme Gardens

What’s Blooming:  Theme Gardens
by Andrew Scott, Seasonal Gardener, Gardens on Spring Creek

We are well into summer now, and our gardens have been using their flowers to advertise to pollinators: “Nectar here, inquire within! Reproduction, whoooo!!”  In spite of the recent onslaught of sweltering temperatures, all of our gardens are doing well – constantly changing as different plants cycle through vegetative growth, blooming, fruiting and going to seed. While all our gardens are based around specific themes, our Theme Gardens are a more specific collection of native and cultivated plants.  Composed of five gardens, the Theme Gardens are each small enough to be cohesive on its own, but effortlessly blend together to form a collage of colors, heights, textures, scents and pollinators.

Plant Select is the first garden one encounters after crossing over the bridge, flanking visitors on both sides of the walkway with displays of Plant Select® plantings.  Species in this collaboration of Colorado State University, Denver Botanic Gardens and contributing horticulturalists are chosen to create gardens that are both beautiful and resilient to the unique climatic challenges that Front Range plants endure. Sure, you could visit Plant Select’s website to see what they recommend, or you could get out of the house and meander through the gravel paths to see how these hardy plants would look up close in your own garden!

This garden actually helped me discover one of my new favorite plants: chocolate flower (Berlandiera lyrata). Not only is it a pollinator favorite that can thrive in the heat, but it also enjoys our salty and basic soils, can withstand winter temperatures in excess of 20 degrees below freezing, only needs a foot of moisture a year... and it smells like chocolate chip cookies. Guys. A plant that smells like cookies!  As if we needed more proof of how cool plants are!

With a plant that aromatic, it naturally transitions into the Fragrance Garden, meant to showcase the odoriferous and volatile organic compounds that plants can produce. Raised beds were specifically included in this garden to increase accessibility for all visitors, helping everyone to get their nose in a flower. Immediately upon entering the garden, or even just walking by it, you can expect to experience a deluge of intermingling scents: the fresh and cucumber-like aroma from garden phlox (Phlox paniculata), the slightly sweet florality of sacred datura (Datura wrightii), the minty camphor of the leaves of green wormwood (Artemisia viridis), the unmistakable sulphureous notes of common garden chives (Allium schoenoprasum) and so many more!

The Fragrance Garden shifts into a botanical garden classic, the Rose Garden, displaying the seemingly endless cultivars of Rosa, including classic hybrid teas, grandifloras, floribundas and miniature types. Every color of rose imaginable can be found here, ranging from stark white through sunset oranges, playful and vibrant pinks and exemplary deep reds, complemented by several other species of native forbs, grasses, and vines. Benches and shade structures are spread throughout the Fragrance and Rose Gardens so you can take classy pictures with the family, sit and catch up with friends or simply take a moment to ground yourself in this crazy world.

The Moon Garden is the last part of this collection of gardens. Just based on the name, I had originally thought it was a garden comprised of species hardy enough to live in outer space and help us beautify human space colonies... but alas, this garden is slightly more down to earth, exhibiting species that look the most stunning in low light or attract nighttime pollinators like moths and bats. Here you can expect to find more roses and sacred datura, as well as plants like white diamond sedum (Sedum pachyclados), false white indigo (Baptisia alba var. macrophylla) already showing its bulbous fruits, the alien-looking succulent iceplant (Delopsperma congestum) and moon carrot (Seseli gummiferum)… are we actually sure this garden didn’t come from outer space...?

The final theme garden is detached from the previous four, located down the main path just before the Foothills Garden. The Hummingbird & Butterfly Garden was designed to be especially attractive to hummingbirds and butterflies, not just for food but shelter as well. The garden is cut in half by a paved path, allowing one to walk the garden and experience it from all angles. Here one will find coneflowers (Echinacea spp.), rough goldenrods (Solidago rugosa), ornamental onions (Allium stipitatum), baby’s breath (Gypsophila paniculata) and native grasses like prairie dropseed (Sporobolus heterolepis). Few people realize the impact that our native grasses can have on pollinator wellbeing, so our horticulturists emphasize their placement within arrangements whenever possible!

Whether you’re looking for hardy plants for your own garden, a sensory experience that goes beyond simply sight, a picturesque and classic garden to take in while taking the weight off your feet, a seemingly extraterrestrial plantscape or perceiving potential pollinators, the Theme Gardens offer a wide range of species to keep any visitor engaged!

Hornworms by Brionna McCumber

Gardeners in Colorado may find large green caterpillars with an iconic horn on their plants every summer—these are hornworms! Tobacco hornworms ( Manduca sexta ) feed on common garden crops, often leading to conflict with humans. These very hungry caterpillars are defoliators, damaging plants such as tomatoes, peppers, potatoes, and eggplant. While the caterpillars use crops as a food source, which could be seen as negative, the moths provide a critical step in reproduction for the plants via pollination. Carolina Sphinx Moths ( Manduca sexta ), also called Hummingbird moths, are the adult form of hornworm s. They are known for their unique ability to hover mid-flight. Combined with the use of a special elongated proboscis, these moths are especially important for plant species with long tubular flowers that other pollinators cannot access or pollinate.  The Gardens on Spring Creek Butterfly House wants to highlight the importance of these specialized pollinators in our...

Winter Watering by Bryan Fischer

O ne of the brightest spots of living on the Front Range of Colorado is its winters. With more than 300 days of sunshine annually, we seldom see extended periods of the grey, chilly, precipitating skies common in so much of the country. It’s not unusual for daily highs to make it above 50 degrees. Much of this we have our elevation and distance from an ocean to thank – our sunlight is more intense than at sea level and our humidity lower, resulting in greater warming during the day compared to regions of similar latitude to our east or near a coastline .    Unfortunately for many landscape plants, however, that same day-night temperature differential spells trouble when paired with our lack of soil-insulating snow cover.  The resulting environment of warm days, frequent wind , and intense sun increases water demand, while low humidity saps the soil moisture reserves that our limited precipitation may provide. As a result, our landscape plants are predisposed to dehydration-indu...

Conifers: Pining for Something Different by Bryan Fischer

Evolving considerably earlier than flowering plants (angiosperms), conifers represent a long-lived and successful lineage of trees classified as gymnosperms. Gymnosperms were among the first true seed-bearing plants and evolved before specialized pollinators existed, so they are typically wind-pollinated. Seeds on these plants are produced between or on scale-like structures (think pine cone scales), rather than in fully enclosed structures, like tomato fruits. Gymnosperm, in fact, is Greek for “naked seeds,” so just imagine what that might imply for the origin of the word “gymnasium” … Long-lived, adaptable and attractive year-round, conifers represent a silver bullet of sorts for our Colorado gardens. Sadly, the overuse of just a few species and cultivars of these plants has given them a bad name. Don’t be put off – judicious use of conifers makes perennial plantings “pop” and provides structural bones during the fall and winter months.  Below, find a selection of underused, adap...
