- Starting indoors: shiso
Shiso (perilla) is a fragrant Japanese herb with large, ruffled leaves in green or purple varieties. It has a unique flavor combining mint, basil, and anise.
Nye County, Nevada is in USDA Zone 8b. The average last spring frost is May 6 and the first fall frost is October 14, giving you a growing season of approximately 161 days.
At an elevation of 3,654 feet, Nye County receives approximately 9.8 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 97°F, so Shiso may need afternoon shade and extra watering during peak heat.

Shiso Heat Requirements (GDD)
What are Growing Degree Days (GDD)?
Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.
Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.
