I saw these beautiful flowers at the Botanical Gardens in Athens, Georgia and asked what they were...I was told they are Threedom Tulips by Colorblend in Connecticut but cannot find them here to post. They didn't have a tag on them.
This is the description from the Colorblend website.
Title: Tulip Blend Threedom - Colorblends.com
Description: Colorblends' Tulip Blend Threedom provides a rolling spring display built on three gorgeous orange tulips, each with a different look and bloom time. Planted as a blend, the three tulips flower in sequence in the same garden spot. First up is a soft orange tulip with a large elongated flower that pops against the bare landscape of early spring. Next comes a double tulip, gold flushed with red that reads as fiery orange in the mid-season garden. Finally, an orange lily-flowered tulip takes center stage, its reflexed petals lightly washed in sunset shades of deep rose and a hint of purple. Colorblends is a Connecticut-based flower bulb wholesaler that is known for tulip blends that consistently deliver jaw-dropping spring displays.

It isn't in the database because it's just a mix of three different tulips sold by Colorblends. They don't name the tulips used in the mix, so it probably depends on what they have in stock in those colors. If you have photos, you can add them to the generic page for tulips.

Use the caption line to note that it's the "Threedom" blend.

Thank you @zuzu

Yes, they describe Threedom as three distinct colors: https://www.colorblends.com/Wh...
