How To Plant in July And Keep Your Gardens Alive!
1) Before planting , prepare the soil by adding 2″ of compost and dig it into the to top 6″-8″ of soil OR Add 1″-2″ of expanded shale with the compost, then dig it in. This will open clay soil, increasing both porosity (aeration) and water holding capacity. Set the prepared soil aside.
We are in the last week of Pollinator Month. We still have a lot of good pollinator perennials and shrubs. Our pollinator garden is looking beautiful and many plants have labels. This garden was given a boost last spring by a grant from People and Pollinators Action Network, plus a lot of Harlequin’s plants. Last Saturday Mikl led a tour of the garden for the Garden Conservancy a national nonprofit working to share and celebrate America’s gardens.

As much as we are looking forward to summer heat and sun, we will be equally grateful for a bit of cool, shady respite. Many of us living in older neighborhoods enjoy mature trees that provide quite a bit of shade. These present a challenge: what plants will thrive beneath them and in their shadow? Right now, Harlequin’s has our biggest selection of plants for dry shade, moist shade, and moderate shade.[Read More]

Harlequin’s Gardens is famous for our selection of Native Shrubs. Not only do we have them when few other nurseries do, but we know them and we have mature specimens planted in our display gardens. These woody plants that are so well adapted to Colorado conditions are often drought tolerant, low maintenance, bee and pollinator-supporting, wind-tolerant, cold-tolerant and good-looking. Like many shrubs, some benefit from a once-a-year pruning to remove dead flowers before they make seeds. This will make them more tolerant to drought and snow and wind, but seeds can be left for the birds and pruned late fall.
Native shrubs can be grown together for a very water-wise and low maintenance garden that is tied together visually with a fine woodchip mulch.
Fernbush (Chamaebatiaria millifolium) is a beautiful Plant Select® shrub that is usually 4’- 6’ tall and wide with fern-like leaves that come out in mid January or February. It is very tolerant of dry conditions, heat and bright sun. In summer, clusters of small white flowers cover the bush densely and often bloom a little more in fall. These flowers are extremely attractive to beneficial insects, especially native, non-aggressive wasps which help keep down populations of pests and are intent on pollen, not people. This shrub is tough enough for the back 40 and attractive enough for the front yard. It can be sheared (or pruned) lightly after blooming for a tidier appearance and to encourage rebloom. Fernbush is native to Idaho, Utah and northern Arizona.
Fernbush
Chilopsis linearis is called Desert Willow because it has narrow, willow-like leaves and is very drought-tolerant. It is a small tree 6’-15’ with an open structure and does not leaf out until May, even late May. It is related to Catalpa tree and Trumpet Vine. The orchid-like flowers are so surprising and breath-taking; ruffled, trumpet-shaped, pink to red-purple, striped purple inside. Chilopsis prefers dry, loose soils, but clay is OK if it is seldom watered. At night it is visited by hawkmoths and is scented of violets according to Bob Nold. He also says it “…is the toughest shrub that can be grown in our garden…I have never watered my plants.” The flowers bloom for a long time and are followed by narrow pods that are not messy. Chilopsis is native to New Mexico, Nevada and Utah. Books often say it is hardy to zone 7, but we have specimens over 10 years old at Harlequin’s and Denver Botanic Gardens has many older trees. Often, the flowering tips die and look better pruned off.
Dwarf blue rabbitbrush
Dwarf Rabbitbrush (Ericameria or Chrysothamnus) has been called The Gem of the Tribe. It is a compact shrub 1’-2’ high and 2’-3’ wide with short and narrow bluish leaves and clouds of golden yellow flowers in throughout autumn. The flowers are very attractive to pollinators; it is a crucial late-season food source, supplying nectar and pollen for native bees, honeybees, Monarch and other butterflies, moths and even hummingbirds. Once established, this shrub thrives with little or no watering. It also provides a welcome display of color in the late season and if it is sheared after flowering, will stay compact and attractive enough for the front yard. It is native near Harlequin’s in the open and dry high desert and steppe, and in much of Colorado.
Solidago ptarmicoides
Looking for a really different native Goldenrod? Solidago ptarmicoides (aka Oligoneuron album) is distinctive within the Solidago genus in having white to cream-colored daisy-like flowers, in heads arranged in a flat-topped cluster rather than in an elongated raceme. Known as Prairie Goldenrod or White Upland Aster, one plant can sometimes produce as many as 50 small heads, blooming from August to October. It is an herbaceous perennial that grows in clumps 12 to 24” high and wide, native to dry, sandy, usually calcareous soils, cracks in rocks, limestone pavements, rocky outcrops, grassy slopes and prairies from Quebec to Saskatchewan south to Arkansas, and west to Colorado. It’s cold-hardy to USDA zone 3.

These are native plants that we often have for sale during the growing season. Availability does change every year, but we grow and buy a wide variety of natives because they are so successful in our gardens.

Penstemon virgatus
Few genera are as synonymous with Western North America as penstemons or beardtongues. The genus is almost entirely native only to North America with the center of diversity falling west of the 100th meridian. Over 250 species are found in North America with one outlier in
Japan. The outlier is often placed in its own genus. Penstemons are native to every state in the union except Hawaii and almost every Canadian province besides Nunavut.
Gary Meis teaching
Last Saturday a group of dedicated plantspeople came in from the cold to learn and volunteer with Harlequin’s Gardens’ expert propagator Gary Meis. We’re passing a few of his native plant seeding and propagation tips along to you.
So they can support us!
Last Friday Denver Botanic Gardens hosted a day-long conference on Tree Diversity. This timely subject arises because of the importance of trees to the livability of our cities and suburbs and the degree to which the effects of Climate Change have already begun to affect our urban forest. Trees help cool everything from our gardens and patios and parking lots to our cities and our planet. With stresses like sudden, dramatic temperature changes, drought, and severe windstorms, plus the devastation wrought by the Emerald Ash Borer to our millions of Ash trees, it’s time to re-evaluate the limited palette of trees we’ve been planting for many decades, and investigate new, more resilient possibilities.

Attractive Evergreens for Colorado Gardens
At the time of the Winter Solstice, we can be grateful for the evergreens in our Colorado gardens. Not every region of the temperate northern hemisphere can grow so many different beautiful plants with year-round presence.
There are so many evergreen (and eversilver, everblue, red and purple) hardy perennials, groundcovers, shrubs, herbs, and trees (and not just conifers!) we can grow here. They go above and beyond in their service as ornamental plants in all four seasons. [Read More]
