Colorado is a great place to cultivate herbs such as lavender, oregano, rosemary, and thyme. For the herb garden of your dreams, you’ll need to learn more about the herbs, the advantages they provide and key elements that encourage their growth.

A Closer Look at Growing Herbs in Colorado

Herbs and flowers that don’t form woody stems when they’re grown above ground include lavender, rosemary, thyme, and basil. During the winter months, these herbs die down to their roots and return to the ground. Many people appreciate herbs for their aroma, flavor and medical properties.


One of the best herbs to cultivate in Colorado is lavender. Lavender may appear to be dead in the early spring, but by the end of April, the herb will begin to show signs of life. Pruning below the plant’s points of new growth will destroy it, so bear this in mind when deciding to cut down on the plant.

That this herb has a wide range of characteristics, such as hardiness, flavor and growing rate. Marjoram (Origanum majorana), for example, needs to be replanted every spring because of its exceptional sweetness. Although it lacks the sweetness of majorana, the Italian oregano (O. x majoricum) is favored for its hardiness and reputation as a clumper.


Getting rosemary plants to live for several years might be difficult for many individuals. It is possible, though, if you plant rosemary cultivars like Arp and Hill Hardy in a suitable location and cultivate them properly.


This highly-aromatic herb’s tiny blue blossoms are enticing to pollinators in late April. There are many uses for citrus-flavored green and golden lemon thyme, but they don’t have the staying power of their cousins. The best time to cut back on your thyme plants in Colorado is in the late summer, when the plants are most vulnerable to freezing temperatures.


In the event that you wish to plant basil in containers, make sure that nighttime temperatures consistently fall in the 50s or above. Flowering occurs in the first half of summer while basil is in its leafy stage.

As soon as the flower stalks appear, you should begin cutting back the stems for harvesting before the flavor becomes bitter. Basil’s growth slows down when the evenings get cooler in early October. It’s a good idea to harvest your basil during this period of time.

Six Great Easy-to-Grow Herbs for Your Colorado Garden

Colorado is a great place to produce herbs, and there are numerous benefits to doing so. Hundreds of different herbs can survive in Colorado if we provide them with the fundamental necessities they need to live, and they’ll return the favor by enhancing our meals and making our world smell pleasant and delightful. When it comes to giving our pollinators a little something extra, herbs are a terrific option.

Large, showy flowers aren’t going to be seen on herb plants. As a matter of fact, herbalists advise us to remove the blossoms as soon as they appear. All of the plant’s energy will be channeled into the oils, which are responsible for the leaves’ flavor and perfume. Then again, as a beekeeper, I prefer to leave blossoms on the plants until they begin to wither away. The lovely nectar that many herb plants produce is beloved by my honey bees. Many native bees and other pollinators enjoy nectaring on flowering herbs.

Growing herbs in your Colorado garden, whether in pots or in beds, is much simpler than you may expect. Throughout the year, Tagawa Gardens sells a wide range of herbs, but when summer approaches, the selection expands even further. If you’ve never tried growing herbs before, now is the moment.

It’s all about the basil

Every time I give a session on herbs, I begin by asking the class which plant is the most popular among the herbs. The winner is always basil.

There are over twenty varieties of basil in the Tagawa’s herb garden as the season starts each year. Many cooks swear by the classic “Sweet” or “Italian” basil varieties. However, there are many more to pick from, such as the spicier “Thai” basils, available. Bright sunlight and a rich, yet well-drained soil are essential for all of them.

I prefer “African Blue Bush” basil. As a disclaimer, I am not a gourmet chef. (I’m a terrible cook, to be honest). There is a rumor that I have a 5-ingredient cap. A simple Caprese salad, made with fresh tomatoes, olive oil, balsamic vinegar, mozzarella, and basil, calls for a lot of African Blue Bush flavor.

Because the plants are so large, I grow African Blue Bush. That’s why it’s called a “bush.” The bees can’t get enough of the beautiful arching spikes of small lavender flowers that form when I let them to flower. I consume the blooms and young leaves raw, and I also gather them for uncooked usage. They’re bursting with the wonderful flavor that first drew us to basil.

It’s not uncommon for African Blue to be a bit of a bully and completely fill a pot by itself. As a result, I’ve learnt not to expect it to share my space with other herbs. Many of the other basils are more tolerant of sharing a pot with other herbs, and they’ll do OK in a larger pot. They do, however, seem to welcome some coverage from the hottest midday heat.

Give it room to develop and strong, but not harsh, afternoon light. The African Blue Bush will not let you down!

They’re cute.  They’re pretty.  They’re purplish pink!

At the very least, plant some chives in your Colorado garden to see whether you can successfully cultivate herbs. Seeds and miniature plants, which Tagawa’s sells all year long, are the easiest ways to grow them. Potatoes prepared in a variety of ways benefit greatly from the addition of fresh chives. These onions are fantastic for enhancing the flavor of a wide range of foods, including soups, stews, and salads.

Growing chives in a clump in a vegetable or flower area is a lovely sight. Only let them self-sow cautiously. They’ll run from one area of your garden to another on a regular basis.. Picking and choosing where to let them go is fine as long as you remove the surplus. Too many “volunteers” are a bad thing. Most of the time I let them roam free in a designated area. The nectar in the tiny ball-shaped petals is too much for my own honey bees and tiny native bees to resist, therefore I have learned to coexist peacefully with them.

A little parsley, for flavor or garnish

Both parsley and chives share some characteristics. You can start them from seed or a little plant and they’ll grow quickly. However, if you turn your back on them, they’ll spread quickly.

The type of parsley called “curl leaf” is the most commonly used as a garnish. Those deviled eggs are inside my five-ingredient limit now, so I can see and taste them. In spite of its lack of flavor, curled-leaf parsley is attractive enough to thrive as a decorative plant. Flat-leaf parsley, often known as “Italian” parsley, is used largely in culinary preparations. Both are easy to grow and don’t require a lot of attention. Unlike chives, though, they will readily reseed if grown in beds without removing the blossoms.

Take note of the “parsleyworm,” a gorgeous caterpillar that eats parsley. With stripes of turquoise, black, and yellow, this caterpillar is one of the most beautiful I’ve ever seen. The parsley it craves is all yours! On the verge of becoming the swallowtail butterfly, this caterpillar must consume an enormous amount of nectar to get there. Why not grow an additional batch of parsley in a pot or two?

Some perennial herbs?

Basil and rosemary are both very popular herbs. Small plants can be grown in a sunny spot on your deck or patio in no time at all. Rosemary has woody stalks and resembles a shrub. A cactus mix, for example, provides excellent drainage for this plant. Rosemary is not a fan of sitting in soggy ground!

There are two types of rosemary that can withstand the cold weather outdoors at Tagawa Gardens. Lina is one of our Perennials Department’s most knowledgeable gardeners. Arp rosemary thrives on a hillside that receives little rain. In general, she explains, it will last for approximately five years before it succumbs to a very frigid winter. If temperatures don’t fall too low, “Madeline Hill” may be able to withstand the winters here for a few years.

It’s easy for me to cultivate rosemary in a large clay planter on my deck or patio. This plant thrives in the summer and produces silky, aromatic needle-like stalks. Small blue blossoms are left on for the bees.

But I’m not going to fool my rosemary into thinking it’s a houseplant by bringing it inside for the winter. Instead, I store it in an open, but unheated, back porch. In my warm, dry indoor environment, it likes the cold. It can tolerate temperatures as low as 20 degrees Fahrenheit as long as I remember to water it. I give it a trim in the spring, and it’s back outside. I change it every a few years since it becomes woody at the base and no longer looks or produces as much as it used to.

Find time for Thyme

You may be surprised by the variety of thyme you can plant. The culinary thyme available at Tagawa’s works wonderfully in pots. It is possible to grow thyme indoors on a windowsill in full sunlight. A well-drained soil and full light are required, but thyme will grow in partial shade.

In his herb garden, 9News Garden Guru Rob Proctor (who also teaches at Tagawa Gardens on a regular basis) grows a beautiful variety of time. The thyme known as “Creeping Red” actually has pink blooms, and it has a lot of them. Low, tight mats around beds containing other delectable foods, such as basil and garlic. Honey bees frequently visit his thyme borders during the summer.

Tagawa’s also sells a brand of ornamental thymes dubbed “Stepables,” which can endure light foot traffic and grow in walkways between pieces of flagstone or pavers. It’s beautiful, but it’s not edible.

Mmmmm….   Lavender!

Let me get on my soapbox now: In Colorado, there are two plants that even inexperienced gardeners can cultivate in a tiny space. Lavender and garlic are the two main ingredients. In September, when Tagawa’s hosts its annual “Ga-Ga for Garlic” Festival, we’ll discuss about garlic.

Let’s start with lavender. Lavender is one of my favorite scents. Lavender is a favorite nectar source for honeybees. Lavender is a favorite of nearly everyone I know. It’s also simple to raise, as long as you provide it with two things. It necessitates at the very least six hours of bright, direct sunlight per day. It also need soil that drains well. Keeping lavender’s roots too damp is the easiest way to kill it.

As soon as lavender is “established,” meaning that it has been growing for at least a couple of seasons, it can handle drought. In the first two years, I learned the hard way not to ignore good, thorough watering. That’s not something I’ll do again.

It is not a suitable houseplant like rosemary, which has woody stems. Put it outside in a garden bed or a large pot, say eight inches wide, and you’re ready to go! Lavender can be grown as an annual in a pot, but the scent and flowers are worth the effort.

“Hidcote” and “Munstead” are two well-known perennial lavenders in Colorado that thrive. It’s called “Phenomenal” for a newer variation. Some varieties of lavender are particularly well-suited to being cooked with. For some, crafting is the ideal career choice. Check if the plants you’re drawn to are annual or perennial before planting them to get the greatest results. Spanish lavender, for example, has large blooms but is an annual. To help you find the right plant for your needs, our Perennials or Herbs Department professionals are here to help.

The Tagawa Herb Day on June 17th and the “Lavender Fields Forever” event on July 22nd are a must-attend this year. This year’s Lavender Festival focuses on plants that grow well in Colorado and the many ways in which they can be used once the flowers are harvested.

Which Herb is Easiest to Grow?

Thyme is a breeze to grow because it doesn’t necessitate as much maintenance as other herbs do. This must be done, however, a few of weeks before the last spring frost. Thyme is a self-sufficient plant that requires simply sunlight, dry soil that drains, and a small amount of fertilizer to thrive.

Can You Plant Supermarket Herbs?

You can, in fact. Make sure that the roots of the herbs you bought at the grocer are still linked to the stems. Make careful to soak the roots of the shop herbs in water for at least 24 hours as soon as you reach home.

The following step is to plant the herbs in moist, well-draining potting soil. Carefully irrigate the plant. You can start transplanting new plants as soon as you notice new growth.

Best Reasons Why You Should Give Greenhouse Gardening a Try

In addition to longer growing seasons and the ability to cultivate a wide variety of plants, greenhouse gardening provides protection from the elements.

You can extend your growing season

In contrast to typical outdoor gardening, greenhouse gardening encourages stronger plant growth over a longer period of time. In other words, the growth of plants within the enclosure will not be restricted by changes in the weather.

How to Start Your Own Herb Garden | Gardener's Path

Building your own greenhouse gives you the freedom to experiment with various methods for maintaining a constant temperature, moisture content, and humidity within the building no matter what the outside conditions are. There are several ways to use heating fans, man-made heaters, and solar thermal mass to achieve this.

You can produce a wide range of plant types

In the off-season, you may provide a wide choice of produce by investing in a greenhouse. In addition, greenhouse gardening allows you to cultivate plants that aren’t native to your area. As long as you have a greenhouse, you don’t have to be constrained by the elements when it comes to gardening.

Protects your crops from external threats

You won’t have to worry about harsh weather conditions, varmints munching on your crops, or seasonal pests since you’ll be able to manage what enters and exits your greenhouse.

The Takeaway

Grow your own herbs in a greenhouse now that you know which ones thrive in Colorado’s climate.
