Our research scientists collect a lot of data every summer—and this work can be challenging. From our work in the field, we’ve learned to come prepared to clear one road that is invariably blocked by downed trees. Then there are the hours we spend on our hands and knees keenly searching for and measuring hundreds of individual rare plants. In small plots at study sites throughout each species’ range, we mark every individual and track their fate year after year. </p> This annual data allows us to correlate climate variables to survival and reproduction. We can then estimate the population’s risk of extinction. In addition to the annual demographic monitoring, we are developing methods to efficiently and effectively estimate the total population size</a> of rare plants. Population counts help us estimate the level of genetic diversity within a population. A sufficiently large population can potentially adapt to climate, habitat and plant community changes. Our data serves to address global challenges. An estimated one million species face extinction worldwide. There is a need to prioritize species and put resources to those most at risk. Tools like the U.S. Endangered Species Act</a> and the International Union for Conservation of Nature Red List</a> rely on population counts and predictions of risk. </p> While we annually collect data all over Colorado on six rare species, all of these help improve and promote effective data collection methods. We are chipping away at the biodiversity crisis by collaborating and sharing expertise with federal and private conservation partners. Our efforts are extended through our participation in the Global Strategy for Plant Conservation</a>. </p> The task may be daunting, but I look forward to clearing the way to collect meaningful and impactful data for years to come. </p>

Do you have a family recipe that connects you to your roots? Maybe it’s a recipe that each time you smell it sizzling in the pan, you’re transported to your grandmother’s kitchen. Or maybe it’s a recipe you’ve taught to younger generations so they can continue the tradition. </p> For my family, that recipe is krautburgers. These delicious, hand-held pocket sandwiches are stuffed with sauerkraut and beef, and they arrived in Colorado with a small group of immigrants who came to the United States from Russia but were originally from Germany. Each winter, my dad uses an old family recipe to whip up a huge batch of krautburgers. Eating one feels like tapping into the generations of love and wisdom that made me, me. </p> You can explore the deep personal significance of foods and family recipes in Nourished: Works by Jazz Holmes</a>, opening in the Freyer – Newman Center on Saturday, September 27. Artist Jazz Holmes connects to her Creole background through paintings that celebrate traditional Southern recipes like hoppin’ john, étouffée, bananas foster and more. Discover the surprising history behind staple ingredients and the stories of love and labor that go into making and preserving cherished family recipes. </p> Feeling hungry after seeing art about delicious food?

No matter where your family is from, food has the power to nourish and connect, so share the love! </p> Article contributed by Curatorial Coordinator Katie Foster. </strong></em></p>
Botanic gardens can change the world. Our former CEO Brian Vogt used to say this regularly as he spoke with people about the power of Gardens. There is no better time for botanic gardens to confirm his point than now. </p> As cultural institutions deeply connected with our communities and the natural world, we sit in a place where we can do both the hard work of understanding shifts in our biological landscapes and educate our audiences about these changes and their repercussions. The Gardens’ scientists engage in projects tracking plant and fungal diversity, collecting seeds, producing seeds, understanding genetic influence on restoration success, assessing tree health and long-term population trends. </p> Collaboration is an essential component of our success. As federal policy, regulations and funding availability are shifting, our work is impacted. Now, more than ever, working with others will be required to restore burned and degraded landscapes, conserve species and track shifting species dynamics as invasive species and warmer temperatures change habitats. We need to find new and creative ways to carry our work forward. Leadership around plant conservation is needed now, and Denver Botanic Gardens has a seat at the table.</p> To do this work we partner broadly with public and private entities. Federal policies and regulations shape experimental design and drive our data collection. We aim to understand plant population dynamics and the factors that influence rarity in many of our plants protected under the U.S. Fish and Wildlife Service Endangered Species Act. </p> Based in the heart of the Rocky Mountains, we are leading the North American Botanic Garden Strategy for Alpine Plant Conservation in partnership with Betty Ford Alpine Gardens. Through federal funding we are building an alpine plant atlas to track the location and conservation status of North American alpine plants and are collecting seed of rare species for safeguarding against a warming climate. As federal policies, regulations, and funding have been changing dramatically this year, it creates uncertainty in our work on these projects. </p> In mid-August, I had the opportunity to attend the Plant Conservation Leadership Summit</a>, an event hosted at Atlanta Botanical Gardens and organized collaboratively by the Center for Plant Conservation</a>, the American Public Garden Association</a>, Botanic Gardens Conservation International – U.S.</a> and Atlanta Botanical Gardens</a>. More than 50 conservation and garden leaders from across the country attended in person with another 50 online. The two-day summit presented opportunities to brainstorm, strategize and learn together. We shared approaches for unconventional funding opportunities, policy needs and how to make a good pitch. We talked about the value of storytelling and how we need to do more to put plants back in the national mindset. </p> Three Denver Botanic Gardens’ staff attended, and we all walked away energized and committed to not only enhancing the role that the Gardens plays in our local conservation landscape, but on a national and international stage as well. Many opportunities are on the horizon, and we are ready to use our expertise to lead. Despite the uncertainty that has hit our field and our funding this year, I am inspired and hopeful about our future and the opportunities to conserve plants. </p> So, in alignment with what Brian would say, botanic gardens are poised to save the world—or at least make a really good effort to protect it together. </p>
A new school year has arrived, the light is changing, and the final days of summer are coming to an end, which means autumn is around the corner. When people think about autumn in Colorado they think of the hillsides covered in brushstrokes of gold, but there is so much more to the changing of the seasons here if you take a closer look. There is no better place to see these colors in a landscape than at Denver Botanic Gardens. </p> Luminescent Perennials</h3> Begin on the path in the O’Fallon Perennial Walk and notice the luminescent color of the Salvia azurea</em> var. grandiflora</em> (pitcher sage) which shines amidst a backdrop of our native Juniperus scopulorum</em> (Rocky Mountain juniper). Within this garden, you will see many other perennials and grasses donning their yellows and oranges of the season.</p> Follow the path to the Fragrance Garden and search for the Buddleja alternifolia</em> (fountain butterfly bush). This shrub begins stunning our visitors in the spring with fragrant, lilac-purple flowers, but the weeping, fountain-like shape and the soft green and grey leaves are just lovely. A cool fall day is the perfect setting for a mindful stroll through this garden. </p> Unexpected Color</h3> Keep walking west and you won’t have to go far to see the unexpected colors of the late-blooming dahlias in the bed on the south border of the Four Towers Pool. This garden has many blooms that may offer you a warm feeling, but nothing says “pumpkin spice latte” like Dahlia </em>‘Brown Sugar’. This garden is another perfect spot to enjoy some solitude, listen to the sound of the fountain and reflect on the goodness gardens have to offer. </p> Gorgeous Grasses</h3> Right next door you will come across the Ornamental Grasses Garden, which offers a pleasing palette year-round. During the autumn months the colors and seedheads of the grasses are works of art that shine the brightest. A few that will catch your eye first are Helictotrichon sempervirens</em> ‘Saphirsprudel’ (blue oat grass), Deschampsia flexuosa</em> (wavy hair grass) and Calamagrostis </em>× acutiflora </em>‘Avalanche’ (feather reed grass). Mixed among the grasses is another masterpiece called Sedum </em>‘Dark Magic’ (dwarf stonecrop). This stonecrop is a lovely contrast to the grasses and is easy to find with its purple-black foliage and deep pink flowers. Not only do all of these plants provide seasonal interest, but they also offer food for wildlife. </p> Living Art</h3> Make sure to look through the oversized gold frame on the corner and you can imagine this landscape as an Impressionist painting. This frame is one of several at the Gardens and is part of our Blue Grass, Green Skies: American Impressionism and Realism</a> exhibition. If you want the perfect social media photo op, this is the spot! To everything there is a season and just like the disappearing blooms and falling leaves of autumn, the exhibit ends on September 14 and the frames will be removed over the following weeks. </p> International Inspiration</h3> One garden that inspires you to slow down and enjoy autumn is June’s PlantAsia just down the sidewalk. This garden is full of trees and shrubs that offer up an endless display of colors and textures; from the beautiful evergreens like Pseudotsuga menziesii</em> (Douglas fir) and Pinus nigra</em> (Austrian pine) to the colorful maples. Wander past the ting, a Chinese pavilion, and find the Acer japonicum</em> ‘Vitifolium’ (full moon maple) as it begins to turn yellow and red throughout the coming months. </p> Maybe you need inspiration for your own home landscape, or you would like an invitation to be more mindful. Whatever it is, the Gardens has a lot to offer this autumn – cozy, colorful and comforting.</p> </p>
Documenting biodiversity is crucial for conservation and is a major aim of our research programs at the Gardens. To work toward this goal, we have been pairing up with the public through community science projects—which invite anyone, regardless of educational background, to be part of the scientific process by recording and sharing their observations of nature. </p> As an example of this, last summer we relaunched Insects Illuminated—a nighttime public event at Chatfield Farms designed to document nocturnal insect biodiversity. Using ultraviolet lights projected onto white bed sheets, we attracted moths, beetles, flies and other insects, documented them with iNaturalist</a> and collected 35 specimens to be deposited in our natural history collections</a>. Experts, staff and volunteers were able to share their knowledge and enthusiasm with those new to the joy of insect diversity. Highlights of the night include the grand elm sphinx moth and brilliant yellow geometer moth.</p> This year we doubled down, hosting the event twice, once at Chatfield Farms and once at York Street. And this year we were very excited to partner with our community engagement team to welcome Young People In Recovery</a> and Westwood Family Nature Club</a> to participate as community scientists at the events.</p> By combining the wonder of discovery with meaningful scientific contribution, events like Insects Illuminated demonstrate how community science can simultaneously advance conservation goals and foster deeper connections between people and the natural world around them. As we continue expanding these collaborations, we're not just documenting species; we're cultivating a growing community of citizen scientists who will carry this curiosity and conservation ethic far beyond our garden gates.</p> This article was contributed by Scientific Data Manager Rick Levy</strong> and Floristic and Outreach Coordinator Alissa Iverson</strong>. </span></em> </p>
Historically, Denver Botanic Gardens has hosted tours of private gardens in spring and early summer. That’s when most gardens boast the largest number of perennials in bloom, and late-flowering trees and shrubs can make a mighty impact.</p> But once the summer heat lets up, many gardens experience a “second spring” in late summer—when early autumn flowers combine with summer’s bounty to create striking sweeps of color at garden-savvy homes.This year, the Gardens has teamed up with the Garden Conservancy</a>, which hosts garden tours across the country, to showcase three outstanding—and very different—gardens close to home. The tour takes place Saturday, Sept. 13. Sign up so you don’t miss them</a>! What better way to spend a late-season weekend?</p> Bosler House</h2> This historical home has been brought to fresh life by owners Jan and Steve Davis, who have lovingly restored the striking Victorian-era house and surrounded it with lush gardens. Visitors will find lavish borders and a stunning potager.</p> Gatehouse Garden</h2> Tim Morgan and Laura Menzer have created a “secret garden”—and a pretty substantial one—in a quiet southeast Denver neighborhood. Morgan, a passionate lifelong gardener, propagates many of his plants in a greenhouse on the property.</p> A newly completed back patio frames a stunning view of the large island bed, which features multiple borders, rock gardens and arbors overflowing with treasures. The entire perimeter of the backyard is filled with plants, including a bog garden, more rock gardens and choice trees. This is truly a garden for all seasons.</p> Kelly Grummons’ Garden</h2> Kelly Grummons is one of the most highly regarded horticulturists in the Rocky Mountain region. His home garden is a showcase of a rich lifetime of gardening—including, of course, his beloved succulents (he is, after all, Mr. Cold Hardy Cactus).</p> Many stock plants can be found in and around several greenhouses on the property, but the real stars this time of year are the island beds south of his home, filled with late-summer annuals, flaming red Zauschneria and remarkable containers featuring succulents. Visitors will also discover gems like rhododendrons in the shady garden. The more you explore, the more you’ll marvel. </p> Denver Botanic Gardens and the Garden Conservancy have partnered for three years to showcase the finest gardens of the Front Range. This is the final weekend of this year’s program—but expect a dozen or more gardens on tour in 2026.</p> </p>
