Monthly Garden Spotlight – December 2024
By RSBG Horticulturist and Assistant Curator Will Clausen While December might be dark, often damp, and sometimes chilly, these characteristics make it perhaps the most atmospheric time of year in the garden.

Monthly Garden Spotlight
March by Emily Joseph March at the garden is a month most known for its variable precipitation, temperature swings, and for being the reason we check the 10-day forecast repeatedly. Frequently extolled in weather lore and age-old adages, it seems like a time-honored tradition for the weather to fluctuate without any predictability. Yet, the balance […]
