A Natural way to fight the winter Blues

We're open all winter, and the houseplants alone are worth the trip. We’ll be getting a head start on next spring's plants - the plant babies are adorable.

While we can't officially prescribe a trip to the greenhouse to cure the winter blues, we've noticed that nobody leaves here looking worse than when they arrived. Side effects may include a new houseplant... or two.

Winter’s Not Quiet Here

Growing Season is Kicking into High Gear

Brighten up a dreary winter day by stopping in our greenhouses! We start our spring plants the week after Christmas, so drop by to witness the progress from tiny cuttings to full-blown beauty. Did we mention it's warm?

Winter is also a great time to stop by and plan out your garden for the following year with help from our knowledgeable staff. AI can do a lot of things, but gardening isn’t one of them yet. Come speak to a lovely human for the garden planning help you need.

It’s the perfect time to start planning your gardens
