Bulbs for Colorado Gardens
At Harlequin’s Gardens, we have been experimenting for years with bulbs in our display gardens. Since our gardens are xeriscapes (by default even where not by design), we have had the pleasure of discovering that a great many delightful bulbs can thrive and naturalize in our conditions and enliven the scene in spring and fall. No surprise, really, since most of these hardy spring and autumn-blooming bulbs originated in parts of the world with conditions much like ours, such as Central Asia. Visitors to our gardens have been wowed by enormous Star of Persia Alliums and brilliant sapphire miniature iris, and charmed by perky miniature daffodils and starry species tulips and crocus. They (you) kept asking us “where can I get these?”, so in 2008, we carefully selected our first-ever offering of bulbs for sale at Harlequin’s Gardens.
Since then, we have added many wonderful varieties, and this year will feature 80 different varieties! Quantities are limited and often sell out quickly. We recommend that you purchase your bulbs in September and hold them for planting when the soil is cooler (except Saffron Crocus and Crocus speciosus, which should be planted in September). Planting depths are to the bottom of the planting hole where the base of the bulb rests. Planting depth can vary depending on how light or heavy your soil is – plant deeper in light soils, shallower in heavier soils. As a general rule planting depth is 3 times the height of the bulb. Single Early, Triumph, Darwin Hybrid, and Multi-flowering tulips should be planted 8″ deep to perform as perennials and fertilized each year just after bloom. Be sure to allow the leaves and stems to wither naturally before cutting them down.
Here are some inspirations for ways and places to use bulbs that you may not have thought of. One idea is to plant small early-blooming bulbs, such as many of the species tulips, where the ground is exposed in spring but will be covered in summer by spreading herbaceous perennials like Desert Four-O’Clock (Mirabilis multiflora), ‘Orange Carpet’ California Fuschia (Zauschneria garrettii), or Wine Cups (Callirhoe involucrata). Also, meadows and drifts of ornamental grasses are usually dormant until mid to late spring, and present a perfect stage for a brilliant display of many types of early spring bulbs. Deciduous groundcovers that emerge in mid-spring, like Plumbago (Ceratostigma plumbaginoides), can partner nicely with Iris reticulata and small species tulips.
It’s been a rough year over in Holland, where the business of flowers and bulbs is a huge component of the economy. Unprecedented heat followed by heavy rains and flooding, combined with labor shortages due to COVID, made the bulb harvest and export very difficult.
Have you noticed that your daffodils and narcissus have been struggling and lost their vigor? Here are several possible reasons why and ways to address reviving them.
Dense, four-inch diameter globes of starry red-purple florets atop stems up to 24” to 36” tall. Very showy, and the earliest large-flowered ornamental onions, blooming in mid-spring. Thrives in full sun to part-shade, and naturalizes by self-sowing. Stunning, long-lasting cut-flower. The dry seed-heads are also highly ornamental in the garden and in flower arrangements.
Circa 1857, this delicate-looking yet easy-growing North American native has composite 3″ globes of star-shaped, sparkling white flowers with pale lavender stamens tipped with purple anthers and sturdy stems.
A most surprising, outrageous flower for xeriscapes! The giant globes, to 10” diameter or more, are held on fairly short stems, 8”-18” tall, blooming in mid-spring. The hundreds of starry, silver-lavender florets each have a green ‘eye’ are arranged so that their petal-tips touch to form a perfect sphere. This easy naturalizer has been highly successful in our xeriscape display gardens, eliciting lots of interest. Also spectacular in large flower arrangements, fresh or dried.

This fall-blooming crocus emerges as a cheery surprise in October or November with bright violet-purple open cupped petals and brilliant orange stigmas, the source of the precious spice, saffron. The blooms are accompanied by short blades of dark green, grass-like foliage which elongates after the flowers have finished and may re-appear in spring.
The superb blue Autumn Crocus, blooms in early to mid-autumn, arriving to brighten the garden at a time when many other plants have finished blooming. Autumn Crocus has large, sky-blue to purple flowers with golden-orange stigmas and anthers. They stand 4” tall and emerge without the narrow grassy foliage that will follow bloom. They will naturalize, and over the years, the clumps increase in size and duration of bloom.
Crocus vernus varieties bloom later and have larger flowers than ‘botanical’ crocus. They create a big, cheerful splash of color in the spring garden that few hardy plants can achieve. This mix contains a compatible blend of purple, yellow, white and striped varieties that will all bloom at the same time.
