In the Garden: Plant bulbs this fall for a colorful display next spring

With the growing season rapidly coming to a close, you might not want to hear there’s one extra task to do. However, this one will add color to your garden when you’ll want it most. I’m talking about planting specialty bulbs this fall to brighten up your flower beds in the spring.

Most gardens have at least a few tulips or daffodils. We all love them but there are so many other interesting bulbs that are often overlooked. All of the following should be planted after a killing frost and before the ground freezes.

One of the earliest bulbs to bloom in my garden is Glory of the Snow (Chionodoxa). With a height of 4 to 8 inches, they’re rather diminutive but they make up for it with their perky 6-petaled flowers in white (Alba), lavender-blue (Blue Giant) and pale pink (Pink Giant). The bulbs spread at a manageable rate, giving gardeners more bang for their buck. They’re hardy down to USDA zone 3.

Siberian squill (Scilla siberica) is a deer-resistant bulb that also slowly spreads. I love the intense blue flowers of Spring Beauty (zone 3, 4 inches) and hope to acquire some meadow squill (S. litardierei) after reading about their lavender to royal-blue blossoms. They’re hardy to zone 4 and grow up to 8 inches tall.

Most gardeners are familiar with petite snowdrops that have white-and-green nodding flower heads but I want to go bigger. Giant snowdrops (Galanthus elwesii) have larger flowers, grow up to 8 inches tall and are hardy to zone 3. An alternative is summer snowflake (Leucojum aestivum) with similar flowers but a height of 12 to 15 inches.

Grape hyacinths (Muscari) are fairly common in gardens so I’m looking for more unusual cultivars. The Scheepers catalog writes this about Ocean Magic (M. aucheri): “sparkling like a sun-dappled ocean, each stem has a cobalt-blue base that gradually blends into a wave-frothed white tip.” Sign me up for that one. The blossoms of White Magic start out pale green and mature to a pristine white. Both are hardy to zone 4 and grow 6 inches tall.

Other Muscari of note include Golden Fragrance (M. macrocarpum) with purple-topped, yellow flower spikes that are lightly fragrant (5 inches) and feather hyacinths (M. cosmosum plumosum) with their violet-colored, ethereal flower plumes (10 inches).

Every year when I go on garden tours, I resolve to plant the alliums (flowering onions) I’ve seen. By the fall, I’ve usually forgotten all about it, but not this year. Alliums are tough, deer-resistant and bloom in May and June; most are hardy to zone 4.

The purple globes of Star of Persia (A. christophii) remind me of fireworks and grow 18 to 24 inches tall. I love the blue-green, strap-like leaves and white spheres of Ivory Queen (A. karataviense), which reaches 10 inches in height. And while drumstick allium bulbs (A. sphaerocephalon) aren’t necessarily uncommon, I always appreciate how terrific they look when planted in nice groupings within a bed. They grow 24 inches tall.

Globemaster (A. christophii x macleanii) bulbs are a bit pricey but they make a jaw-dropping impression in the garden with their 10-inch-diameter violet spheres and 24- to 36-inch-tall stems.

Looks like it’s time to put together my shopping list.
