Florals for spring? Groundbreaking.

Nothing says springtime like fragrant flowers and fresh vegetable gardens, so if you want to gear up for what we’d consider the best season, opt for a greenhouse kit. Not only does it dress up your backyard space, but it keeps your plants protected from the elements. In most cases, greenhouses can even extend the growing season, so you can enjoy whatever it is you’re cultivating for as long as you want.

As you may have inferred from the term "kit," all of our picks are DIY-friendly, but if you don't consider yourself an expert with power tools, worry not. All nine of our favorite finds are actually pretty easy to assemble. Some, in fact, simply snap and slide into place—no tools required. From an elegant Colonial-style greenhouse with a split door and ventilated windows to an Old World–inspired find made entirely of polycarbonate (a super durable plastic that looks and feels like glass), there are a lot of solid picks out there. Luckily, we've rounded up the best ones, so consider this your guide.

Like a pool house, a greenhouse is designed to stay put all year, so once you build it, there's no need to take it down any time soon. In fact, they work best in the winter when temperatures can dip so low that your plants become endangered. Greenhouses basically give them a place to ride out the worst months until spring has sprung. So if you want to flex your green thumb in time for House Beautiful's Backyard Escapes issue release, go ahead and explore these stylish greenhouses kits before they’re sold out.

This Colonial-style greenhouse kit may be on the pricey side, but just look at it. This crisp white structure will surely spruce up any backyard. It also comes pre-assembled with flooring, ventilation, shelves, and a door. So, all you have to do is coat it with paint.

This stylish greenhouse kit can double as a gazebo if the weather is right. Fill it with your delicate blooms or enjoy it as your own personal al fresco dining spot. The Old World–inspired structure is made from anthracite powder-coated and rust-resistant aluminum, so you know it will hold up.

Available in two sizes, this traditional greenhouse kit prioritizes ventilation to give your plants the optimal environment for growth. It's also easier to build than it looks, with just a few panels and a frame made of corrosion-proof and weather-resistant powder-coated aluminum that's been thickened to stay standing through any weather event.

Trust us; your plants, flowers, and vegetables will never be happier than they are in this modern walk-in greenhouse, which will extend your growing season by months, courtesy of the transparent panels that keep your plants warm. The birch frame also gives it a slightly warmer and more welcoming feel that the traditional transparent greenhouses we're used to seeing.

There's something comforting about a completely transparent greenhouse kit, in which all of your flourishing plants are on full display at all times. This is one of our favorites because it comes in four sizes and two colors, including the green pictured here and a glossy steel. Here's the thing: It may look delicate but it's actually one of the most sturdy options on our carefully curated list. It's made using a rust-resistant aluminum frame and virtually unbreakable polycarbonate panels.

Don't let the enormous size of the Grand Gardener greenhouse fool you into believing it will take months to put together. The weather-proof frame utilizes a pin-and-lock system and the roof panels simply slide into place—no tools required. Plus, unlike some other greenhouse roofs, this one diffuses more than 70% of sunlight to deliver your plants with a soft, even light.

With adjustable roof vents and two sliding doors, this greenhouse is a sure winner. It may be simple, but it gets the job done (read: keeping your plants alive and healthy). The whole unit ships in just two boxes with all the instructions, hardware, and required tools included. Did we mention it only takes a few hours to build?

This is another greenhouse that doesn't necessarily need any plants to serve a useful purpose. Fill it with a few lounge chairs, an end table, and maybe a few outdoor lights, and you've got yourself a cozy al fresco gazebo-like nook. It's made of a durable ABS plastic and finished with thick cloth. Water-proof and wind-resistant, you can enjoy a light rainstorm from this plastic igloo. Just be sure to take it down under heavy rainfall or snow.

For those who would rather opt out of the complicated building process, this easy DIY greenhouse kit is for you. It features a SmartLock connector system, which means you can throw the heavy-duty aluminum frame together quickly and without much hardware. The split door and vent windows are even pre-assembled, further minimizing the amount of time you have to spend building. It may not be small, but at just 72 inches wide, it's ideal for a backyard without room to spare.

If you have all of the materials and tools already on hand, it may be cheaper to build your own greenhouse from scratch, but if you'd have to buy all of the required elements, it may be cheaper to just buy a greenhouse kit.

Greenhouses are not technically supposed to be warm in the winter, but, if they're built correctly, they should be at least 20 degrees warmer than the outside temperature. Plants rarely need warmth to survive, but they generally won't make it in sub-freezing temperatures, which is why greenhouses come in handy.

The House Beautiful shopping editors may focus on interiors most of the time, but we are pretty knowledgeable when it comes to all things gardens—especially the homes in which our plants live. So when tasted with finding the best greenhouse kits, we scoured the Internet in search of great options at various price points.
