Because 'Astro' has wider leaves and is slower-to-bolt than other arugulas, you will be enjoying more leaf per harvest and a longer harvest period. With its milder flavor, it makes a delectable baby green, harvestable in just about a month! The peppery flavor many of us love ramps up over time and as spring temperature heats up. Afternoon shade helps prolong the harvest. Also a good container variety.
