General Information

Plant Form Flower Plant Size 3′ x 3′
Plant Type Annual Water Usage Medium
Sunlight Sun Flowers Yellow

Physical Description: Curious, small, green to purplish tomato-like fruit completely enclosed in a thin, papery, light-green husk that dries tan. Fruit is found summer into fall on long, sprawling stems with dark green foliage and yellow petaled blossoms.
Care and Maintenance: Hornworms. Root rot if over watered and mildew if sprinkled
Gardener’s Notes: There are several native Physalis species but this one produces tasty, edible fruit that makes great Salsa Verde and other dishes. Grow from seed. A heat loving relative of the common tomato, tomatillo will set fruit long after it becomes too hot for tomatoes. Tomato, Lycopersicon esculentum, does fairly well in El Paso if given frequent regular irrigation, Some good heat resistant tomato varieties for El Paso include “Better Boy”, “Ace”.

Southwest Plant of the Month – Orange zexmenia – Wedelia texana (Zexmenia hispida)

General Information

Plant Form Flower Plant Size 3′ x 2′
Plant Type Perennial Water Usage Low
Sunlight Sun, Partial Shade Flowers Yellow

Physical Description:  Sub-shrub with coarse foliage forming rounded mound of long-stemmed, yellow sun flower-like blossoms. Blooms steadily from late spring to fall.

Care and Maintenance:  Dies to ground with hard freeze. Sprawls in shade. Deadhead to maintain blooming.

Gardener’s Notes:  Long lived, well behaved Chihuahuan native. Cultivar “Devils River” is commercially available. A hardier, tougher Chihuahuan relative, Jefea brevifolia (Zexmenia brevifolia) or Short-horn Zexmenia, has similar flowers on short stems and makes a low, rather tidy mound of small ovate leaves with a rough sandpaper texture but is not commercially available. The genus name Zexmenia was once misapplied to these plants in error but lingers as a common name.
