Iris tectorum Japanese Roof Iris
About Our Plants
Rare Roots ships live, growing plants in one-quart pots all over the continental US. The rare exception is our slightly smaller 3.5" inch pot, which will be labeled on a few product pages.
The plants are not guaranteed to be blooming when they arrive, and the foliage may need to be trimmed before shipping to fit them in the box safely.
Our Guarantee:
Our plants are guaranteed to arrive safely in a suitable condition for planting. If they are damaged or if you have concerns, please inform us right away by sending pictures to info@rareroots.com. Even if you are planning to wait and see if it recovers, we need to document the damage on your order.
We are not able to offer warranties or extended guarantees on plants due to the sheer number of variables that can affect their growth and survival.
About Perennials:
Our plants are grown on our 30-acre outdoor nursery in Virginia (available by mail-order only). They are all considered "perennial" if planted within their preferred zone range.
Perennials planted in the coldest zone listed are considered "tender perennials", and may not overwinter in a severe winter. For example: if a plant is rated for zones 7-10, it would be a tender perennial in zone 7. It's best to plant these in spring or early summer, and preferably in a protected area (such as the South side of building).

Description
Iris tectorum has wide, lilac-blue to purple flowers with white crests and dark veins in early midsummer. Its dense fans of broad, ribbed, glossy green, sword-like leaves are 12" long. The foliage may become a bit floppy with age. A perennial, Iris tectorum spreads rapidly to form a medium-height ground cover.
Also known as Japanese Roof Iris, Iris tectorum prefers part sun to sun with some afternoon protection and moist to average, well-drained soil. It is drought tolerant, once established, but maintains its best appearance with consistent moisture. Japanese Roof Iris responds well to fertilization during the growing season.

Shipping Info
Fall Shipping Schedule 2025 Coming Soon
Check back within the next week to see our shipping schedule based on growing Zones.
Due to increasing temperatures, we have stopped shipping plants in the summer for their best interest.
We only ship on Mondays and Tuesdays to ensure that plants can travel during the weekdays.
Plants take 2-3 days to arrive after you receive a notification that they've been shipped.
We appreciate your patience while our small team works to get your plants to you safely! If you need a specific shipping week, you are welcome to let us know by leaving a note on the Cart page or replying to your order confirmation email.
Our boxes come in four sizes: 1-count, 3-count, 6-count, and 12-count.
To get the best shipping rates per plant, try to fill a box of 3, 6, or 12. Shipping rates are calculated at checkout by weight, package size, and distance.
Our nursery is located in Virginia, and it can sometimes be costly to ship to the western US. Ground shipping is too slow cross-country for the plants to arrive safely, so our options are limited to faster shipping methods. We appreciate your understanding!

We ship via UPS or USPS (the Post Office), and their ship rates are automatically generated through our site. We do not profit on shipping costs. We are working with these providers to get our customers the best rates possible.
All ship times are subject to change if extreme weather conditions are present here at the nursery or at the shipping destination.
Please note: Depending on the time of year, the foliage of the plants may be trimmed to fit into our shipping boxes. This could delay the flowering of the plant, but many perennials actually benefit from being cut back.
We are currently not able to ship to Puerto Rico, Hawaii, and outside of the US.
