This Week in the Greenhouse

From the greenhouse

Caleb Schlegel

This week is a mix — some weather, a new favorite, some industry news, and a peek at what’s actually happening behind the greenhouse doors right now.

First up: the Omega Block meteorologists have been talking about. After a wet Indiana spring, a stretch of stable weather is exactly what most annuals need — and a lot of gardens are about to look dramatically better.

Second: I named my plant of the year, and it’s Monarch Magic Ageratum — a pollinator magnet with the vigor of a landscape plant. Third: a quick note on the new Dümmen Orange / Syngenta Flowers partnership and why it actually matters for what shows up at your garden center.

And below this letter — the full article — a look at what’s happening at the greenhouse right now. Spring may be winding down for shoppers, but fall production has already begun.
