Why You’ll Love Purple Shamrock

Beyond its dramatic foliage, the Purple Shamrock performs a graceful nightly “dance” (nyctinasty), folding its leaves at dusk and reopening at dawn. Its folklore associations with luck and renewal make it an enchanting gift or focal point.

Frequently Asked Questions

Shipping

How do you ship your plants?

We carefully package each plant with love by hand right from our shop in Brooklyn. Extra steps are taken to ensure that every leaf arrives in pristine shape by using polyfill and encapsulating the plant in a protective paper sleeve. The soil is also hydrated before shipping so that the plant has plenty of water for it's travel to your doorstep. We offer several shipping speeds, so please choose the one that you feel comfortable with depending on your location. 

Will my plant look like the one on the website?

Awesome question, we're glad you asked. Given the nature of our plant shop, we're constantly moving plants in and out of the shop, making it difficult and borderline impossible to keep an exact picture of each plant. In addition to the constantly rotating crop, we often grow in batches of 6, 12, or sometimes more! With this quantity we are unable to take a photo of each and every plant. The photos that we attach to each product listing is going to be of a plant that represents the average size and fullness of that set of plants. Some may be slightly larger or smaller, but in general, similar.

Do you include heat packs with your plants?

We offer Heat Packs for sale separately from the plants in 40, 60 and 72 hour increments. Please add a heat pack or two to your order if you live in an area where your order may be affected during transit by cold temperatures. We are not responsible for orders that are placed and damage is incurred to the plant if a heat pack is not purchased.

Which heat pack should I choose?

Heat packs come in three different increments, so please choose the appropriate hour increment depending on the speed of shipping that you choose during checkout. For example, if you choose a cheaper shipping option that will take longer, please select the 72 hour heat pack. If you've chosen a shorter method of shipping, the 40 or 60 hour increment would work! We like to encourage our customers to always get more than you need, just to be on the safe side!

How long will it take to receive my order?

Standard shipping normally takes 3-5 days. Next day shipping is available on all domestic orders (for an additional charge). International shipping times depend on the products and destination (estimated at checkout).

If you have circumstances that require expedited fulfillment, please connect with you and we can potentially offer options.
