Indigo is among the oldest dyes to be used for textile dyeing and printing. Many Asian countries, such as India & Japan have used indigo as a dye for centuries, however they used differing plant species to produce the dye. Dyer's Knotweed, as this variety is known, is a tropical heat loving plant which is why we gave it a try at our urban farm, which is in Plant Hardiness Zone 10b.Our experimental indigo patch flourished last fall, producing two flushes of harvestable green growth and then proliferated an abundance of viable seed. Once established in your garden your Japanese Indigo plants can also be propagated easily from cuttings. We suggest gardeners growing Indigo in the tropics plant in Fall or winter. While using fresh indigo leaves for its famous dark blue hues does involve some advanced technique and processing fresh leaves can be used to create subtle tons of aqua, teal and green, depending on the fabric, mordant & water used. If your indigo starts making beautiful long seed flushes while it’s still young just prune them off to encourage it to make more leaves instead.


All of our plants are produced using OMRI certified organic materials (potting mix, fertilizer & pesticides) however our nursery is not certified organic. Plants are shipped in compostable peat moss pots and we use heirloom & organic seeds whenever possible.

Shipping & Returns

We ship plant orders every Monday. Due to the nature of shipping plants we only offer expedited shipping for our live plant orders. Our returns & exchanges policy is also quite strict since its hard to control the quality of a plant once it leaves our facility, however we do our very best to make sure that each and every customer is satisfied with their plants. Read more about our policies here. 


All of our plants are potted in 4" pots and their foliage size varies based on how large the plant is naturally when its root ball is the correct size for the pot. If a plant is too tall for our shipping box we may prune it to fit (bonus: many plants do better after being pruned since they make bushier growth). We do our very best to ship all of our plants in the "sweet spot" of maturity however so long as the roots have colonized the pot we will consider a plant mature enough to ship.

Care Instructions

When you receive your plant its critical to get it out of its box and into the light the day it arrives. It will also want to be removed from its compostable plastic wrapping and given fresh water to drink. Keep in mind, this plant was grown in the tropical humid climate of South Florida, so if it's terribly cold or dry where you are it'll need to be hardened off before planting outdoors. Visit our care instructions page for more thorough info about caring for your new plant friend.
