The first Colorado asparagus appeared at the Boulder Saturday Market last Saturday, and I nearly bought every bunch in sight. The stalks were thick, deeply green, and so fresh they practically snapped when I bent them—exactly what you want this time of year. If you’ve been waiting for the season to actually turn, this is your week. Late April in Denver marks that brief window when spring produce starts arriving but before the summer corn-and-tomato chaos arrives. Here’s what you should actually be hunting for at your local market this week.
Colorado Asparagus — The Star of the Week
Let’s talk about the vegetable everyone is quietly competitive about at the market right now. Colorado asparagus is having its moment, and if you’re not paying attention, you’ll miss it.
Why Colorado Asparagus Is Worth the Hunt
Colorado’s San Luis Valley and Western Slope regions produce asparagus starting in mid-to-late April, making this one of the most anticipated seasonal arrivals at Denver markets. The high-altitude climate creates growing conditions that produce stalks with a more concentrated, slightly sweet flavor than what you’ll find shipped from other states. I’ve been buying asparagus at Boulder County farms for years, and the difference between truly fresh Colorado asparagus and grocery store specimens from Mexico is honestly night and day.

Here’s the honest reality though: asparagus typically only appears for about six to eight weeks at local markets before the plants are done for the season. That’s a short window. Peak Colorado asparagus season runs through May, making late April ideal for first harvests that are both abundant and at their freshest. Get there early—I’m talking before 9 AM at the Boulder Saturday Market, which runs year-round on the downtown mall at 13th Street between Canyon Boulevard and Arapahoe Avenue—if you want first-pick stalks rather than what’s left after the early crowd descends.
How to Pick the Best Stalks
Look for firm, bright green stalks with tightly closed tips—avoid anything with spreading or wilted tops. The thickness matters less than people think; thin stalks aren’t necessarily tougher, they’re just from younger plants. What you’re looking for is that snap when you bend the stalk near the bottom. If it bends without breaking cleanly, put it back. I made the mistake last year of grabbing a bundle without checking, and two out of three bunches were already softening by the next day. Trust your fingers as much as your eyes.
Spring Greens Beyond the Basics
Asparagus gets the glory, but the real value at markets right now is in the spring greens. After months of storage onions and root vegetables, fresh greens feel like a small miracle.
Hydroponic Operations Bringing Year-Round Variety
Denver-area hydroponic farms bring texture to markets even in shoulder seasons—expect to see butter lettuce, baby arugula, microgreens, and spicy mustards showing up consistently. These operations don’t get the romantic attention that soil-based farms do, but the quality is genuinely excellent, and the fact that they’re producing year-round in our climate is worth appreciating. Several Front Range hydroponic vendors at the Old South Gaylord Market on Sundays have been reliably stocked since early spring, and I’ve been picking up their arugula for weeks already. Yes, it’s greenhouse-grown, but it’s genuinely local within a few hundred miles, and the carbon footprint of a Denver greenhouse is meaningfully different than asparagus flown in from Peru.
What to Look For This Week
Look for bundles of spring mix from Palisade-area farms arriving at Denver markets now. Palisade sits on Colorado’s Western Slope about 250 miles from Denver, and while the distance disqualifies it from “local” in the strictest sense, these farms are producing under conditions that are markedly different from conventional agriculture. The volcanic soil and high-desert climate give their greens a sweetness that Front Range growers struggle to replicate.
Spinach from Colorado’s Eastern Plains starts appearing in late April from farms near Fort Collins and Greeley. This is your signal that outdoor growing is finally underway—these farms are dealing with real weather risk and later frost dates than Denver proper. When I see Eastern Plains spinach at market, I know the season has genuinely shifted. Early season kale and chard are hitting stalls now too, and they’re noticeably lighter and more tender than later spring cuts. Buy them now and treat them gently—they’re not the hearty winter versions, and they need to be used within a few days.
Early Radishes and Spring Onions
These are the underdogs of spring markets, and honestly, they deserve more attention than they get.
The French Breakfast Radish Window
Late April marks the peak of French Breakfast radish season. These elongated red-and-white radishes with peppery bite are showing up at Boulder and South Broadway markets now, and they’re worth seeking out specifically. Unlike the round red radishes you find year-round, French Breakfast radishes have a more complex flavor—there’s the initial heat, then a sweetness that lingers. I eat them sliced thin on buttered toast with coarse salt, which sounds almost insultingly simple, but it will change how you think about radishes.
Look for bunches with fresh, vigorous greens still attached—the tops are edible and great in salads or sautéed with olive oil and garlic. If you’re seeing limp greens, the roots are probably past their prime too. This is one case where visual inspection of the whole bunch actually tells you something useful.

Spring Onions and Scallions
Spring onions and scallions from local growers in Erie and Lafayette are typically abundant this time of year. Both towns are north of Boulder along the Front Range, and their microclimates and soil conditions produce onions with a sweeter, less pungent flavor than what you’ll find in grocery stores. I’ve been buying scallion bunches from a vendor at the Pearl Street Market in Lafayette—located on Pearl Street between Public Road and Campus Drive, running Saturdays 9 AM to 1 PM—and they’ve been consistently excellent for weeks now. Ask for them by name and don’t settle for the stored onions.
Early-season carrots may also start appearing from farmers growing under row covers in the Front Range. Row covers are those lightweight fabric row blankets you see stretched over raised beds—they extend the season by a few weeks and protect young seedlings from late frosts. If you see carrots at market in late April, they were almost certainly grown under cover, which means the farmer made a calculated risk that paid off. These carrots are often smaller and more irregular than grocery store specimens, but the flavor is concentrated and noticeably sweeter.
Fresh Herbs Arriving in Bunches
Fresh herbs are one of those categories where market quality absolutely destroys grocery store options, and late April is when things start getting genuinely good.
What Herbs Are Coming In
Cilantro, parsley, and dill are typically available year-round from local producers, but late April brings fresher, more vibrant bunches as outdoor growing begins. There’s a meaningful difference between greenhouse cilantro that’s been sitting in a cold frame for weeks and field-grown cilantro that was harvested the morning of market. The outdoor stuff has more color, stronger fragrance, and that essential oil intensity that grocery store bunches lose within days of harvest.
Early thyme and chives from high-altitude farms are hitting markets in late April. These hardy perennials emerge first in Colorado’s variable climate because they’ve adapted to survive temperature swings that would kill more tender herbs. The thyme bunches from Boulder-area high-altitude growers have a concentration that I’m convinced can’t be replicated at lower elevations. Chives are appearing with their lavender blossoms still attached—those flowers are edible and beautiful in salads or as a garnish, if you’re comfortable with the slight onion flavor.
Storage Tips for Market Day
Here’s a practical tip: tie herbs in loose bundles with damp paper towels in a plastic bag to keep them crisp on the drive home from market. I’ve ruined too many bunches of cilantro by tossing them in a bag and finding sad brown stems two hours later. The damp paper towel method works for all tender herbs—cilantro, dill, basil if you’re lucky enough to find it—and will easily double their shelf life. Store them stem-down in a jar of water in the refrigerator, loosely covered with a plastic bag, like you’d treat fresh flowers. Yes, really.
Vendor Types to Look For at Denver Markets This Week
Not all vendors are created equal, and knowing what to look for will significantly improve your market haul.
What to Ask For
High-altitude growers from areas like Boulder, Longmont, and Erie typically bring spring produce first due to favorable microclimates and season-extension techniques. These areas benefit from elevation, well-drained soils, and sometimes creative infrastructure like hoop houses and cold frames that let farmers get ahead of the traditional planting calendar. When you find a vendor from one of these areas, you’ve probably found someone who can tell you exactly when something was harvested, because they’re operating on a smaller scale with fresher inventory.
Ask vendors specifically about where their farms are located—Colorado-grown should be your baseline, not just “local.” Some vendors travel significant distances to set up at Denver markets, and that’s fine, but you deserve to know. A farm in western Nebraska calling themselves local to Denver is technically at a farmers market, but they’re not what most people mean when they’re seeking Colorado farmers market seasonal produce in April. The good news: most vendors are proud of their location and happy to tell you exactly where they’re growing.
Markets Worth Visiting This Week
The Boulder Saturday Market, Old South Gaylord Market on Sundays, and the Pearl Street Market in Lafayette are known for having strong spring produce selections in late April. Each has a distinct personality and vendor mix worth exploring. Related: Colorado Sourdough Bakers Doing Something Special
The Boulder Saturday Market operates on the downtown mall and has been running for decades—it’s genuinely one of the oldest continuously operating markets in Colorado. Parking is challenging; I usually park in the convention center garage at 1330 Canyon Boulevard and walk a block, which is worth the five-minute walk versus circling for fifteen minutes. Get there by 8:30 AM if you want first pick of anything popular.
Old South Gaylord runs Sundays from 9 AM to 2 PM along South Gaylord Street between Alameda and Mississippi Avenue in the Wash Park neighborhood. It’s a smaller market than Boulder, with a neighborhoody feel that’s honestly more enjoyable when you’re not in a rush. The produce vendors tend to be less overwhelming in volume but high in quality, and several have been bringing consistent spring greens since March.
The Pearl Street Market in Lafayette is worth the drive out of Denver proper. Located on Pearl Street between Public Road and Campus Drive, Saturdays 9 AM to 1 PM, Lafayette has developed a surprisingly strong market scene over the past few years. The vendor mix skews toward smaller organic growers, and several are using season-extension techniques that produce results weeks ahead of what conventional farms can manage.
One practical note: greenhouse and hydroponic vendors are especially reliable in shoulder seasons when outdoor crops are still establishing. Look for them toward the center of market layouts rather than on the perimeter—they’re often positioned there by market organizers because they have consistent product regardless of weather. If it’s been a cold, wet spring like we’ve had this year, these vendors may be your only source for tender greens until the outdoor growers catch up.
CSA and farm stand vendors often have the freshest picks since they’re bringing what they harvested that morning rather than wholesale stock. You’ll usually pay a bit more, but the difference in freshness—especially for delicate items like spring mix and herbs—is noticeable in the kitchen.
Get to Market Early This Week
If you’re taking one thing away from this, let it be this: go early. Like, actually early. The asparagus will sell out. The French Breakfast radishes will sell out. The first-cut spinach from Fort Collins will sell out. Late April at Colorado farmers markets is a special, fleeting window, and the produce won’t be around for long. We’re maybe three weeks from when tomato and corn season starts crowding out the spring offerings, so every weekend between now and then is worth protecting.
My specific recommendation: plan a market trip this Saturday morning, hit the Boulder Saturday Market or Pearl Street Market in Lafayette, and buy asparagus as your anchor ingredient. Roasting it with olive oil, salt, and lemon is my go-to preparation when I want to taste what Colorado produce actually tastes like. Don’t overthink it—just get it home the same day you buy it, and make it that night. That’s the whole point of eating seasonally: you eat it when it’s extraordinary, not when it’s adequate.
