I don’t know whether these crocus only came up today, or whether I only noticed them for the first time, today. Whatever, they’re pretty young. And if this blog were more than a year old, instead of less than a year old, I’d know that planting was safe x number of days from the first crocus (at least on this patch of land). I would also have the sequencing (phenology) in mind, so I would know whether it’s usual (again, on this patch of land) or not for lilacs to have budded before the crocus emerge.
The shot doesn’t show this (maybe next time) but the thyme is planted inside slightly raised bed with a rock border. I wonder if the rock serves a heat sink, warming the soil for the crocus.
