Fun Facts
- 🌱 Lime Glow Juniper can withstand temperatures as low as -40°F (-40°C), making it one of the hardiest ornamental shrubs for extreme climates.
- 🌱 The bright yellow coloration in the summer is retained throughout the year, unlike some junipers that fade to bronze or dull green—the 'Lime Glow' name refers to this persistent luminous quality.
- 🌱 Junipers are technically not conifers like pines or spruces, but rather are members of the cypress family and produce fleshy, berry-like cones called galbuli that are actually modified cone scales fused together.
