The Weekly Bloom: Week of August 14th

• Stalks of Color: Do not underestimate the ordinary goldenrod (Solidago var.) for color and texture this time of year. (And it’s ragweed that will make you sneeze, not goldenrod!) Prairie Dock (Silphium terebinthinaceum) grows in the Rock Alpine Garden. It has large leaves at the base, with thin stalks of yellow flowers waving above. For spherical blue flowers, catch Globe Thistle (Echinops ritro) in bloom in the Birds and Bees Garden, and...

The Weekly Bloom: Week of August 9th

Honeywort (Cerinthe major) grows in the former Drop Dead Red border (northeast of the Monet water garden), is a reseeding annual, and has a gorgeous, subtle, blue-green-purple color scheme. • Painted Jewels: Two plants caught my eye this week for their standout color. Euphorbia marginata grows just south of the Water Garden Gazebo. Its variegated leaves shine white (with just a little green thrown in for fun.) And hidden in the underbrush in...

At the entrance to the Rose Garden, Rosa ‘Distant Drums’ changes colors from peach to pink as it opens. • Hardy Hibiscus: August is the season for hibiscus! Although we typically think of hibiscus as delicate tropical flowers, our summer-blooming hardy hibiscus are both tough and gorgeous.

Quick...before it's winter!

It seems far fetched to think that winter is on the way--especially now that we're sweltering in Denver--but one of the features of the alpine tundra is that summer is never more than three weeks away! Allium pikeanum on Mount Goliath One of the many things that I love so much about our tundra is the enormous variety of scale: look up and you can see much of Colorado at your feet....

The Weekly Bloom: Week of July 23rd

Check out the kohlrabi (Brassica oleracea) in the All-America Selections Garden. A relative of cabbage, this plant looks like it flew in from outer space. • Fruits: Find the hidden mayapples (Podophyllum peltatum) with their red fruit in PlantAsia. And yes, the profuse apricot blossoms did not disappoint this year; the trees in the Scripture Garden are laden with fruit. Favorite lunch spot this week: Climb to the high hidden bench in Gates...

Flavors to Savor in the Boettcher Memorial Tropical Conservatory

When it is as hot outside (and inside the Boettcher Memorial Tropical Conservatory), as it has been, I tend to find myself eating more ice cream. Last night as I was enjoying a mixed bowl of chocolate and vanilla ice cream, it made me think about two of my favorite plants in the Boettcher Tropical Conservatory:  Theobroma cacao, or chocolate, and Vanilla planifolia or, you guessed it, vanilla. V. planifolia is...

• Heat Lovers: Senior Horticulturist Dan Johnson, who oversees many of our xeric gardens, notes that the Russian sage (Perovskia atriplicifolia) is in full bloom just now, providing waves of lavender flowers and a dry, sagey scent. He also calls out the Mexican cone flower (Ratbidia columnifera) for its vibrant golden or red-gold colors. See both in the Water-Smart Garden and elsewhere. • Whites: Now is a great time to catch a few...

• Creepers: Ranunculus ‘Buttered Popcorn’ crawls in and out among the plants in the Perennial Walkway, brightening the bed with its variegated leaves and yellow buttercup flowers. And out in the xeric Wildflower Treasures garden, you can see plenty of Ruellia, a wild form of perennial petunia covered with lavender flowers. Then stop by the Lilac Garden to see the intertwined leaves of both the green and gold versions of Creeping...
