Some crevice gardens look like regular gardens where flowering plants cover all the rocks. Others look more like rocky alpine mountainsides. The Denver Botanic Gardens latest crevice gardens combine sculptural placement of the rocks with native plants.
So keep at eye out for a crevice garden near you. Botanic Gardens around the world are investing millions of dollars installing crevice gardens that highlight the art of stone and alpine gardens, and that provide us with ideas of how we will keep growing beautiful plants and flowers even as global warming reduces our available water in some places.
The skies were gray this morning. The landscape was brown and dead. I kept looking for Spring but at best there were just the green tips of bulbs appearing among dead leaves. Maybe the buds were swelling on trees. It was cold, but it still felt like Spring. How could that be?
The loud demanding chirping of some birds interrupted my thoughts and I realized I could HEAR Spring. So I took a listening walk to a nearby pond and while I couldn’t really see Spring…the pond scenery was just as brown as my yard was…but now I knew…nature is waking up.
I could hear the male birds in rapt mating calls…doing their best to make some new baby birds. Lots of mating and birthing going on in Spring. I could hear some tiny chirps that I think were baby sparrows or finches. There was rustling in the winter leaf debris. I couldn’t see anything but I could guess there were baby caterpillars and insects under there that the birds were scratching to find. I suspect there were little mice in there too. Which meant that snakes were waking up and slithering in the grasses.
There wasn’t much to see, but I could hear nature erupting in new life. Spring is noisy. A nature walk in January is pretty quiet except for some chickadees and perhaps large animals running off, startled by a human invading their wild territory. But Spring makes an absolute racket. Even the water is noisy. A week of warm weather had melted ice and brooks were babbling again.
Very early Spring is subtle. I know from the sounds that new life is starting. But it’s a slow lazy waking up. Snow is coming later in the week and I’m reminded of the adage that March is the snowiest month.
The avid gardener has just a few tasks in early Spring. One is to enjoy nature without having to work to weed or control it. Another is to do some pruning while the trees and shrubs are still dormant. But after a cold morning walk, the best thing this gardener can do is go inside and start some more seeds under the lights. Outside, Mother Nature can call the shots. Inside, I’m getting a head start on all those seeds that I want to grow now!

Hope Jahren has helped me fall even more deeply with seeds and the natural world this week. Our book group just started to read her best selling book “Lab Girl.” Lab Girl is like two books in one….a marvelous account of her life as a woman in science AND a romantic ode to nature that waxes poetic about seeds and trees and vines that want to climb.
Here’s her excerpt about seeds:
“A seed knows how to wait. Most seeds wait for at least a year before starting to grow; a cherry seed can wait for a hundred years with no problem. What exactly each seed is waiting for is known only to that seed. Some unique trigger-combination of temperature-moisture-light and many other things is required to convince a seed to jump off the deep end and take its chance—to take its one and only chance to grow.
A seed is alive while it waits. Every acorn on the ground is just as alive as the three-hundred-year-old oak tree that towers over it. Neither the seed nor the old oak is growing; they are both just waiting.”
I love seeds. I love to walk up and down the aisles of the BBB Seed warehouse and touch the hundreds of thousands of seeds that are there, full of potential. To imagine just a single packet grown out and burst into bloom. Hope Jahren has given me yet another vision: all those seeds there. Alive. As alive as the trees outdoors. Alive and waiting. Waiting patiently and calmly.
Get your Fireworks and start your 4th of July party now. One of my favorite things about perennials is that you plant them once and they bloom year after year. Their appearance every year becomes one of the sweet rituals of the garden. Bright red Firecracker Penstemon is a favorite neighborhood ritual of mine. Some 15 years ago an older lady in the neighborhood planted red firecracker penstemons around her mailbox on the street. She called it the 4th of July flower because the little stand of 3- ft tall red flowers that had grown around her mailbox in the hot beating sun were always in bloom on the 4th of July. Over time, the display got more elaborate as purple salvia were planted at the base of the penstemon. Later white alyssum was growing all around in the rocks. It was a true red white and blue extravaganza.
A few years later I noticed other mailboxes in this suburban neighborhood had firecracker penstemons growing up around them. The whole street was decorated for the 4th of July. I never did find out if everyone liked the idea and planted penstemon too or if some middle of the night guerilla gardener spread penstemon seed everywhere.
Firecracker penstemon is a good choice for mailboxes in the sun next to the street because it tolerates high heat and drought which both plague mailboxes in the sun next to concrete sidewalks. The only caveat is that penstemon is one of those perennials that doesn’t bloom until its second year, so you’ll have to wait a bit for the start of your annual your 4th of July explosion of red.

As a gardener I often say “Thank God.” The growing legality of growing marijuana has meant a proliferation of stores that sell amazing tools and new agricultural products that make gardening easier and cheaper. Despite living in Colorado, I’ve never been interested in smoking pot. Even as a decadent college student I thought “Why smoke when you can drink?” I helped a friend trim some of her high end organic marijuana grown outside and declined the offer for some of the product. But I am endlessly interested in marijuana growing techniques. I have three products that might not have been available if it weren’t for the early mmj growers.
My EZ Clone aeroponic plant propagator.
These used to cost $400 but I got mine for $50 off of craigslist from a guy in a souped-up muscle car who had had dreams of getting rich by growing clones but lost interest when that didn’t happen overnight. Now you can buy new cloners for much less than $100 from Amazon or Home Depot if you aren’t brave enough to venture into a grow shop. These simple machines spray warm mist on the roots of cuttings and cause hardwood and softwood cuttings to grow roots in a very short time—days! This is my favorite way to root shrubs, tomatoes, small fruit plants and even roses. Should work great for trees too. I can have well-rooted plants in just a couple of weeks.
My LED grow light.
The first indoor light I tried were the big sodium ones that provided enough light to take indoor plants all the way to bloom. That was amazing but also an energy hog. This year for indoor seed starting, I’m loving my Costco LED shop light that is half the size of my old shop lights, lightweight, and uses almost no electricity.
My liquid all natural growing supplements.
I still rely on kelp and Superthrive as growth stimulants, but the organic, natural fertilizer concentrates produce some of the best growth and production I’ve seen, especially in tomatoes. Lots of research went into getting ideal growth out of marijuana plants. Marijuana and tomatoes are quite similar in plant needs. If you can grow one, you can grow the other.
There’s nothing like old fashioned common sense for growing using compost and time-honored natural techniques. But a few high-tech products can make your garden spectacular.
Wild arugula is my favorite spring green of the week and this year it’s the first thing I’ve seeded out into the garden during our warm spell.
Similar to regular arugula, wild arugula has a “wilder” taste and thinner leaf. It looks quite like a mustard weed when young if you aren’t familiar with it. Definitely a cool season crop as once the temps get to 80 wild arugula can be quite bitter.
It is very easy to grow, as mustards often are, and can handle less than ideal soil and water. (Watch out…low water makes it even spicier.). I like to plant it somewhere it can establish itself as a perennial that I can just pick a few leaves now and then to add some zest to dinner. But a Spring garden patch is essential to get cups and cups of the greens to use in making pesto.
So here are my three favorite wild and spicy reasons to grow wild arugula.
SPRING SALADS
Arugula has a nutrient profile similar to other spring tonic herbs like dandelion and nettles, but I like the taste even better for salads or lightly steamed.
PESTO
Wild arugula pesto is an absolute favorite. Make it with garlic, olive oil, walnuts and Parmesan or goat cheese and you have a fantastic sauce for fettuccine noodles, topping for pizza or spread for appetizers.
POLLINATORS
Naturally, foods that are favorites of pollinators are favorites of mine. Once summer sets in, wild arugula bolts and sends up tall tiny spiky yellow flowers that pollinators love. I’ve seen all kinds of bees and butterflies snacking on the wild arugula flowers from summer through late fall. I also snack on them….I like the flavor of arugula flowers even better than the leaves.
Scarlet Nantes Carrot is a standard market carrot that has a long, cylindrical shape and a rich reddish-orange color. The flavor is sweet and delicious. Roots are fine-grained, containing almost no core. High moisture content makes this variety perfect for juicing. Carrots can reach up to 7 inches long. To prevent diseases, rotate planting location every season.
Site Requirements:
Light: Full sun. Will tolerate very light shade.
Water: Moderate moisture. Crusted soil can suppress germinated sprouts.
Soil: Well-drained soil with organic matter. The area needs to be free of stones.
Seeding:
This cool-weather crop is easily over-planted due to its fine seeds. Sow seeds directly into loose soil in early spring 2-3 weeks before last frost date. Carrots are slow to germinate, emerging in 2-4 weeks. Cover seeds with a ¼ inch of soil—no more than ½ an inch. Lightly water seeds every day for best germination. Once sprouts emerge thinning is critical to reducing competition. Thin seedlings to 1/2 – 1-inch spacing. Best time for thinning is when soil is damp. Plant seeds every 2-3 weeks throughout midsummer for continuous harvest.
Harvest Time:
Start harvesting as soon as carrots have reached the desired size (up to 7 inches). Try pulling up one at a time to check the size. Watering the area before harvest can make pulling by hand easier. Harvest by mid-September to avoid pest damage.
Fun Facts:
Carrots are a great source of fiber, potassium and vitamin A.
Carrot greens can be used in soup stock, pesto, curries or tea.
Common pest: carrot rust fly
British gardeners plant sage around the area to repel the carrot fly

The Detroit Dark Red Beet is the most popular all-purpose red beet. It is globe-shaped, tender with blood-red flesh that is sweet and delicious. Beets are easy to grow and tolerate a wide range of climates. Beets prefer cool weather; in zones 8-11 where summers can be hot, grow them as a fall, winter or early spring crop.
Site Requirements:
Light: Full sun to part shade
Water: Consistent moisture
Soil: Well-drained, sandy loam soil high in organic matter. Avoid acidic soil areas.
Seeding:
Sow seeds directly into soil in early spring as soon as soil can be worked. Beets tend to have spotty germination. Presoaking seeds for 1-2 hours will soften seed coat and speed germination. Plant seeds ½ inch deep and 1 inch apart. Seeds need close contact with the soil; it is best practice to press down on soil after planting. Sprouts will emerge in 10-20 days. Thin seedlings when they reach 4-5 inch to 3 inches apart.
Harvest Time:
Pull up plants when exposed root tops are 2 inches across.
Fun Facts:
Reddish green leaves make a great addition to summer salads
Planting garlic and mint with your beets will improve the growth and flavor
Beets are very sensitive to toxic substances in the soil and may not germinate if planted near walnut trees or soils containing herbicides

I love blue flowers so naturally I am enthused about our new “Blue Blazes” collection of seeds for eight different blue wildflowers. What really caught my attention is a little flower I’ve never seen growing that now I just have to have.
Nemophila maculata is white with single blue-purple spots on the tips of each of its five petals. So cute. Such an unusual design is believed to have evolved to capture the attention of native solitary bees. “Five Spot,” the flower’s common name, is an early cool-season annual flower that prefers shady moist areas. Although my garden in Colorado is pretty dry, shady areas under trees are well-watered in Spring where the snow is slow to melt in the shade. Perfect I think for a flower whose name Nemophila loosely translates as “woodland lover.”
I’m going to plant my five spots in an area with that has early Spring purple crocuses and early Summer blue columbine. I’m hoping Five Spot blooms just between those two.
Five Spot finishes blooming once the weather gets hot, but it leaves seeds to reappear next Spring. Now I have a new travel destination on my list: California’s Sierra Nevada in early Spring when fields of this sweet wildflower bloom naturally.

If you read just one gardening book this year, I have the perfect book for you. It’s a British gardening book and while growing conditions in merry old England aren’t anything like growing in hot arid Colorado, the advice here transcends climate. It’s about how to get the most flavor and nutrients by “how” you grow.
“Grow for Flavor: Tips and tricks to supercharge the flavor of homegrown harvests” doesn’t just repeat the advice on how to grow organically that is now found in many books or all over the internet. Author James Wong of the Royal Horticultural Society takes growing edibles to the next level by referencing scientific studies on how nutrient content and flavor molecules increase according to growing conditions and cooking methods.
Beets are one example.
If you want more antioxidants, roasting beets doubles their antioxidant levels compared to eating them raw.
If you want sweeter beets, sow them extra early. Sowing beets in cooler conditions leads to increased sweetness and more intense color.
If you aren’t fond of ‘earthy-tasting beets’ it’s the organic compound geosmin that gives that flavor. You can harvest early because young beets haven’t developed as much geosmin. Or you can put vinegar on the beets as my great grandparents did because the geosmin is degraded by acid.
If you juice beets for their cardiovascular benefits, the substances you want more of are nitrate and betalains. To get more of those, sow a mid-summer crop and fertilize with nitrogen to hike cardiovascular benefits by 300%
Another way to hike health benefits is to skimp on the water, Lack of water or ‘drought stress’ increases phytonutrients by 86% and makes beets richer in zinc and iron.
All this info is from just one page of the book so you can see why I love it. And I love my local librarian who procures such unusual books for our local library where I can read them for free!
