Plants depicted in photos are at maturity. We sell starter perennials shipped bare root, as plugs (small plants 1-2 inches x 2-4 inches) or bulbs. Plugs are shipped trimmed to reduce stress during travel. We do not ship plants in containers.
Common Name: Spurge
The unique variegated foliage of 'Ascot Rainbow' is phenomenal and looked fantastic in our garden from spring through fall. It was selected by the Australian hybridizer for its highly ornamental variegated flowers (bracts) and foliage. Narrow, grey-green leaves have a striking yellow edge.
The foliage is topped by clusters of variegated cream, lime, and green flowers (bracts) in spring. In the cooler months, the foliage at the ends of the stems becomes flushed with shades of red, pink, and orange. In our location near Lake Michigan where summer temperatures are a bit cooler, a bit of the pink coloring remained all summer long. We did not observe any reversion in our trials. Overwinters well in zone 5b with excellent drainage.
This plant would make a fabulous specimen in a brightly colored patio container and will undoubtedly add flair to the garden. As an added bonus, it is highly heat and drought tolerant.

Order Details & Policies
No Returns But Replacements
We do not do returns or offer warranties, unfortunately. We simply can't guarantee the future of plants after they leave our shop and are in your care. But the health of our plants upon arrival is something we'll stand by.
Shipping can stress plants. If there are any issues with your plants when you receive them, send us a chat message from our website. We can issue store credits or send replacements.
Also, our starter perennials are small plants. We do not issue refunds because they are smaller than expected. For more details about plant sizes, see Starter Perennials Shipped Trimmed.
Starter Perennials Ship Trimmed
Starters are small, young plants or plugs, bare roots and bulbs. We do not ship mature plants in containers. We will often trim back growth on our perennial plugs to reduce stress on the plants during travel. Trimming does not hurt the plants. They'll bounce back with new growth. You'll receive your plants carefully wrapped and prepared for shipping in a box.
Plant Sizes
Starter perennials are smaller because they are young. Bare roots and bulbs speak for themselves. We have plug sizes ranging from 1-2 inches x 2-4 inches, although some hostas come in larger sizes.
These are not yet plants at maturity as seen in many of the photos on our store. We have photos of real starter plants on some listings and we are working to post more starter photos this year in 2026. We're adding plug sizes to the plant pages, too. Bear with us as we update all our plant detail pages so you are better informed. In the meantime, if you need more details or a photo of an actual starter, send us a message in our chat.
Delivery
Your order should arrive within 7-14 days. Occasionally, we may hold an order so that we can fulfill it with new inventory we are expecting to receive. Just send us a chat if you need a status update.
