Small, spicy tasting root vegetable usually round but some longer varieties. Available in a range of colours between red and white.

Very easy to grow. Good for a child's first garden as seedlings appear in two or three days. Sow between other vegetables as they will mark the rows until the slower germinating plants appear.

Radish will mark the row next door if planted next to some other seeds that come up in more days than radishes. For example if you plant __?__ veggie that comes up in 10 days, next to a row of radishes, the radishes will come up certainly by day 2 ( all things present as to sunlight and water). That mean the ?? veggie will be along side and in next row but not until day 10. That way you know not to plant something else in row space next to radishes. Neat trick I never thought of. Wish I had marked my lettuce groups with one radish seed in middle.
