Verde Tomatillo

The tomatillo (Physalis philadelphica or P. ixocarpa) is a warm-season, shrubby annual in the nightshade family (Solanaceae), often called the Mexican husk tomato. Growing 3 to 4 feet tall and wide, it features trailing, sometimes hairy stems, ovate toothed leaves, and small yellow flowers, usually producing 2-inch, papery-husked, tart green, yellow, or purple fruits. 
Plant Characteristics & Structure:
Appearance: Similar to a sprawling tomato plant, it has a bushy, often prostrate habit, requiring staking or caging to keep fruit off the ground.
Foliage & Flowers: Leaves are ovate and irregularly toothed. Flowers are usually yellow with dark purple or brown spots at the base, borne in leaf axils.
Fruit & Husk: The fruit develops inside a papery, lantern-like husk (calyx) that dries and splits open when the fruit is mature.
Growth Habit: It is an indeterminate, fast-growing plant that produces fruits until the first frost. 
Cultivation & Requirements:
Pollination: Unlike tomatoes, tomatillos are not self-fertile; you must plant at least two to three plants to ensure proper pollination and fruit set.
Environment: They thrive in full sun, well-drained, fertile soil, and warm climates, similar to tomatoes, though they are more heat and drought-tolerant.
Spacing & Support: Plants should be spaced about 18 to 36 inches apart to accommodate their spread.
