Fall Gardening

A Trip to Kendrick Lake Park and DBG at Summer’s End, by Eve Reshetnik Brawner

September 9, 2025

Dalea candida, White Prairie Clover

On Saturday morning, I headed down to Kendrick Lake Park in Lakewood to participate in our local rock garden society’s annual fundraiser, the members’ sale. I always donate some plants, and I always come home with some, too, though I vow not to! It’s also a great time to catch up with friends and fellow members of the Rocky Mountain chapter of NARGS (N. American Rock Garden Society)[Read More]

Terrific Trees for Colorado – on Sale!

September 30, 2025

It’s risky to plant B&B (Ball & Burlap) trees this late in the season. But it’s a great time to plant our Container-Grown trees (like the Golden Rain Tree above)! Why the difference?

A container grown tree has a complete, healthy root system that’s able to start growing in your landscape as soon as it is planted. A B&B tree has been dug from the field where, unfortunately, about 60 to 90% of its roots have been left behind. This means the tree will struggle, needing a lot more water and physical support to establish. A container-grown tree will ‘catch up’ to or surpass a B&B tree in size in just a few years.

CLOSE-OUT SALE on beautiful Patio Trees in classy, outdoor ceramic pots, AND select trees.

A Hardy Geranium Shows its True Colors

September 16, 2025

Among our top favorite groundcover plants for low-water, partly-shaded gardens are Cambridge Geranium (Geranium x cantabrigiense) and its best cultivars. They excel as low-maintenance colorful, long-blooming and long-lived, low-growing, spreading evergreen carpets under trees and in east and north exposures.

Right now we have plenty of cultivars ‘Biokovo’(palest blush), ‘Westray’ (pink), ‘St. Ola’ (white flowers from red buds) and ‘Crystal Rose’(unique vivid pink).

Geranium cantabrigiense ‘Biokovo’

Rarely exceeding 12” tall, they provide dense masses of bloom over attractive mid-green foliage that emits a spicy woodland fragrant when rubbed. A second season of color comes in fall and winter, when the foliage turns shades of red and orange.

Cambridge Geraniums are happy in most soil types, including clay, and thrive in USDA zones 4 through 7. They can also be grown in sunnier exposures with more water, and in full shade with less flowering.

Terrific Bulbs, now 30% off!

October 14, 2025

Allium ‘Graceful Beauty’

We still have some terrific bulbs that want to go home with you, so we’re discounting them by 30%!

Bulb-planting time is here! Spring-blooming bulbs feed early spring pollinators, and help us cheer up as winter recedes. Remember, nearly all the varieties we choose should last for years, even decades in your garden, and most will naturalize, forming larger clumps with a longer succession of blooms every year! And we always favor tough and reliable flowers with fragrance, unique and artistic form and coloration, and minimal care needs. Planting holes are easy to dig with one of our long-nosed trowels or with a cordless drill and an auger bit. Mark the spot with a discreet name-tag or record it on a garden map.

SMALL BULBS
Allium amplectens ‘Graceful Beauty’: 3” fragrant white globes w/mauve anthers on 1’ stems, NW native
Anemone blanda ‘Blue Shades’: long-blooming 1”+  blue daisies on low spring groundcover
Chionodoxa forbesii (Blue Glory of the Snow): brightens any spot in sun or shade
Corydalis ‘Beth Evans’: great early bloomer for shade, maidenhair fern-like foliage crowned with a mass of coral pink
Ixiolirion tataricum: late spring, elegant 1’ blue-purple and low-water
Muscari azureum: gorgeous early azure blue naturalizer
Scilla sibirica: True blue starry blooms naturalize in beds, lawns, meadows, 3” tall
Tritelia (Brodeia) ‘Rudy’: striking, graceful naturalizing California wildflower, late-spring

Narcissus ‘Altruist’

DAFFODILS – deer and rabbit resistant!
Narcissus ‘Altruist‘: Striking deep orange cup and unique tawny yellow perianth, fragrant
N. ‘Barrett Browning’: Brilliant scarlet cup and crisp white perianth, long-lived naturalizer
N. ‘Cornish King’: Very early, wide lemon frilled cup on white perianth, long-lived naturalizer
N. ‘Delibes’: Short yellow frilled cup edged in vivid orange, yellow perianth
N. ‘Double Poets’: Double the fragrance of standard Pheasant’s Eye!
N  ‘Ferris Wheel’: Large frilled orange cup above yellow perianth
N. ‘Golden Echo’: Vigorous Jonquil, several fragrant blooms per stem, long gold trumpet, creamy perianth
N. ‘Jamestown’
N. ‘Mother & Child mix’
N. ‘Mount Hood’: Classic large white trumpet daffodil, lightly fragrant, tall and tough
N. ‘Pheasant’s Eye’: Very fragrant wildflower, late-season, white with small red-edged cup
N. ‘Yazz’: Lovely soft buff trumpet, cream perianth, several per stem, fragrant

and many beautiful tulips are still available!

 

Don’t forget to pick up some bone meal – this amendment helps all bulbs get established.
