Indigo Treat is a University of Saskatchewan haskap, or blue honeysuckle, from the Indigo series. It was formerly tested as 9-91. It came from the Row 9 selections, which also included Indigo Gem and Indigo Yum. The series was named in winter 2011 after propagators and growers asked for names for the Row 9 test plants. Indigo was chosen because of haskap berry color. Blue was avoided because it was already common in names for Russian introductions from Northwoods Nursery in Oregon. [S1]
The Indigo selections were first released as experimental varieties. The program kept them available in case Borealis and Tundra proved hard to propagate or developed field problems. Saskatchewan descriptions tie Indigo Treat closely to Tundra. Bob Bors wrote that it seemed most similar to Tundra, with berries about 10 percent smaller, but much easier to propagate. [S1]
The fruit is described mostly by comparison, not as a full profile. Saskatchewan material says the Indigo cultivars are difficult to tell apart by fruit alone. A figure shows berries of Indigo Gem, Indigo Treat, and Indigo Yum side by side. A later University of Saskatchewan handout describes Indigo Treat and Indigo Yum as similar to Indigo Gem and Tundra, while noting that the authors had not looked at them much. [S1] [S2]
The clearest practical notes concern propagation and grower preference. Indigo Treat was much easier to propagate than Tundra in the Saskatchewan report. The 2019 recommended varieties handout says growers in Eastern Canada were preferring Indigo Treat. [S1] [S2]
These sources do not give a direct zone rating or winter survival statement for Indigo Treat. Its hardiness is supported only by its origin in the University of Saskatchewan haskap breeding program and its inclusion in northern fruit variety material, not by a cultivar-specific hardiness claim in the supplied evidence. [S1] [S2]
Indigo Treat belongs in the University of Saskatchewan haskap group, but the packet does not document its parentage. The evidence supports its former identifier, 9-91, and its place in the Row 9 Indigo series. It should be treated as a related Indigo series selection associated with Indigo Gem, Indigo Yum, Borealis, and Tundra, not as a child or parent of those cultivars unless stronger evidence is added. [S1]
