Planting History: The Value of Perennial Heirlooms

Choosing a perennial heirloom isn’t like picking out a packet of annual beans. You’re making a long-term commitment, dedicating a piece of your land to a plant that will be a permanent resident. These varieties have survived for generations not because they were the most productive in a commercial sense, but because they were reliable, flavorful, and uniquely adapted to home gardens. They are living artifacts, selected by countless gardeners for traits that matter on a small scale.

The real value here is in building a resilient garden ecosystem. Perennials establish deep root systems that improve soil structure and access water and nutrients that annuals can’t reach. They create stability, providing food and habitat for beneficial insects year after year. Think of them as the structural beams of your garden, while your annuals are the furniture you rearrange each season.

This permanence requires a shift in planning. You can’t just rotate a patch of asparagus next year if you don’t like its location. The primary tradeoff with perennial heirlooms is patience and planning upfront in exchange for decades of low-labor harvests. You must consider the plant’s mature size, its sun and soil needs, and how it will interact with its neighbors ten years from now. This isn’t about filling a temporary gap; it’s about laying a foundation.

‘Mary Washington’ Asparagus: A Century of Flavor

Asparagus is the classic lesson in garden patience. ‘Mary Washington’, an heirloom developed in the early 20th century for its rust resistance, remains a top choice for home growers for good reason. It’s known for producing tender, flavorful spears that are far superior to anything you’ll find in a grocery store.

The key to success with ‘Mary Washington’ is preparing its permanent home with care. This means a deeply dug bed amended with plenty of compost and well-rotted manure. You are building a home this plant will occupy for the next 20 years or more, so the initial effort pays dividends for a lifetime. Don’t skimp on this step.

The biggest hurdle for most is the waiting period. You can’t harvest the first year, and you should only harvest very lightly in the second. It’s not until the third year that you can begin harvesting in earnest for about six to eight weeks. This delayed gratification is a tough sell for some, but it’s essential for allowing the plant to build a strong crown and root system that will fuel decades of production. Resisting the urge to cut those first spears is the hardest part, but it’s also the most critical.

‘Victoria’ Rhubarb: The Classic Heirloom Pie Plant

‘Victoria’ Rhubarb, dating back to 1837, is the quintessential pie plant for a reason. It’s exceptionally hardy, vigorous, and produces thick, tender stalks with a perfect balance of tartness and flavor. For many, the sight of its huge, crinkly leaves unfurling is the true first sign of spring in the garden.

This is a plant that demands space and sunlight. A mature ‘Victoria’ can easily spread three to four feet wide, with leaves that will shade out smaller, less assertive neighbors. Place it at the edge of a bed or give it a dedicated corner where it won’t bully other plants. It’s also a heavy feeder, so an annual top-dressing of compost or aged manure is crucial to keep it productive.

Remember, only the stalks are edible; the leaves contain high levels of oxalic acid and are toxic. This is a critical piece of information, especially in a garden with children or curious pets. The tradeoff is simple: you dedicate a significant patch of real estate to a plant with a single primary use (desserts and preserves), but in return, you get an incredibly reliable, low-maintenance source of that unique tart flavor for years.

‘Green Globe’ Artichoke: A Gourmet Garden Tradition

Growing artichokes feels like a luxury, but the ‘Green Globe’ heirloom makes it surprisingly achievable. This variety has been a garden staple for over a century, prized for its large, fleshy flower buds. It’s a stunningly architectural plant, with silvery-green, serrated leaves that make it a worthy addition to an ornamental bed, not just the vegetable patch.

The most important consideration for ‘Green Globe’ is your climate. It is a true perennial in USDA zones 7 or 8 and warmer, where it will produce for several years. In colder climates, it’s often grown as an annual, requiring an early start indoors to produce a crop in its first year. Know your zone and your expectations before you plant. Don’t expect a northern garden to support a perennial artichoke patch without significant winter protection.

Yield can be a consideration. A healthy plant might produce a half-dozen or more large central chokes, followed by smaller side chokes. This isn’t a high-volume crop like zucchini. You’re trading quantity for a gourmet-quality harvest that is nearly impossible to find fresh. It’s a perfect crop for someone who values unique flavors over sheer tonnage.

Lovage: The Forgotten Heirloom Celery Substitute

If you’ve never grown lovage, you’re missing out on one of the most useful and low-maintenance perennial herbs. This heirloom has a powerful, savory flavor that’s best described as a cross between celery and parsley, but more intense. A single leaf can season an entire pot of soup.

The defining characteristic of lovage is its sheer size. This is not a polite little herb for a windowsill pot. A mature lovage plant can grow to be six feet tall and three feet wide, so plan accordingly. Plant it at the back of a border where it won’t overshadow everything else. Its hollow stems can even be used as flavorful, biodegradable straws for drinks.

The main thing to understand is that a little goes a very long way. You will likely never need more than one plant. Its early spring growth provides a welcome celery flavor long before your annual celery is ready. The biggest mistake is planting too much of it or putting it in the wrong spot. Treat it like a permanent, edible shrub, and it will reward you for years with almost no effort.

‘French Sorrel‘: The Tangy Perennial Salad Green

‘French Sorrel‘ (also known as Buckler-leaf Sorrel) is a game-changer for salad lovers. This perennial green produces tender, arrow-shaped leaves with a bright, lemony tang. It’s often one of the first greens to appear in the spring and one of the last to fade in the fall, providing fresh flavor when little else is available.

Unlike head lettuce, sorrel is a "cut-and-come-again" green. You harvest the outer leaves, and the plant continues to produce from the center. A small patch of just a few plants can provide a consistent supply of zesty leaves for salads, sauces, and soups. It does have a tendency to bolt (go to seed) in the summer heat, but cutting off the flower stalks will encourage more leaf production.

The key is to think of sorrel as a flavor accent, not a bulk salad base. Its assertive taste is best when mixed with milder greens. Its perennial nature means you have a reliable source of fresh, tangy flavor with minimal annual effort. Once established, a sorrel patch requires little more than occasional watering and harvesting.

Jerusalem Artichoke: The Hardy Perennial Tuber

The Jerusalem artichoke, or sunchoke, is less of a garden plant and more of a force of nature. This North American native sunflower produces edible tubers that are crisp, nutty, and delicious when roasted. It is arguably one of the easiest and most productive perennial food crops you can grow.

There is one crucial, non-negotiable rule for growing Jerusalem artichokes: plant them only where you want them forever. They spread aggressively via their tubers, and any small piece left in the ground will sprout a new plant. Trying to eradicate an established patch is a multi-year battle. The best approach is to plant them in a dedicated bed with deep borders or in a forgotten corner of your property where they can naturalize without taking over your main garden.

This plant’s vigor is both its greatest strength and its biggest liability. It thrives on neglect, tolerates poor soil, and produces huge quantities of tubers with zero effort. For the hobby farmer focused on food security and low-input crops, it’s a superstar. But for the tidy gardener who likes everything in its place, it can quickly become a nightmare.

Integrating Heirlooms into Your Garden Plan

Bringing perennial heirlooms into your garden requires thinking like an architect, not just a decorator. These plants are the permanent foundation, so their placement is the first decision you should make, long before you think about where the tomatoes and lettuce will go.

Start by mapping your garden’s permanent features: sun exposure, water access, and high-traffic pathways. Then, assign zones for your perennials based on their mature size and needs.

• The Sun-Soaked Wall: A perfect spot for a space-hog like ‘Green Globe’ Artichoke.
• The Back Border: An ideal home for towering lovage or a contained patch of Jerusalem artichokes.
• The Dedicated Bed: Reserve a prime, full-sun spot for your ‘Mary Washington’ Asparagus patch—it’s a 20-year investment.
• The Accessible Corner: Place rhubarb and sorrel where you can easily harvest them throughout the season.

The most common mistake is underestimating their final size. That tiny rhubarb crown or asparagus root will become a massive plant in a few years. Always plan for the five-year-old version of the plant, not the one you bring home from the nursery. By giving them the space they need from day one, you build a garden that works with you, not against you, for many seasons to come.

By planting these perennial heirlooms, you are doing more than just growing food for this season. You are weaving a thread of history into your land and building a more stable, self-sufficient garden for the future. It’s an investment of space and patience that pays back with years of unique flavors and garden resilience.
