Warm climate gardeners say “Ole!” when planting Machu Morado Mexican Petunia in their full sun gardens. Bright purple, ruffled, trumpet-shaped blooms sway over beautiful glossy green lance-shaped leaves providing a long season of color when nights are warm and days are hotter. No need to take a siesta here as this continuous blooming annual is heat and drought tolerant and loves the sun.

Native to Mexico, the Caribbean and South American, Zones 9a to 12b, Mexican Petunia can take the heat. An improved variety, Machu Morado does not send out runners and take over your landscape. It is a safer alternative to native R. simplex. Native Mexican Petunias have naturalized in the Deep South and are hard to eradicate when they become rampant but there is no need to be concerned with this variety.

Machu Morado Mexican Petunia Care

Machu Morado is not a fussy annual in Zones 3-8, in fact it tolerates a wide range of conditions. In northern climates it will bloom sparsely until the heat of summer hits, but when nights cool, flowering slows. It tolerates a wide range of soil pH from slightly acidic 6.1 to slightly alkaline 7.8. It is not a heavy feeder, so unless you place it in containers where it would appreciate the occasional feeding, nothing else needs to be done. Well draining soil is crucial.

Deadheading is not necessary as it drops its spent flowers on its own. Pruning is not necessary either. Machu Morado will attract bees, butterflies and hummingbirds so plant it where you will appreciate the frequent visitors. Pair this tall upright annual with other daisy-like flowers in a wide range of colors for an outstanding display.

Machu Morado Mexican Petunia Spacing

Space plants 10 to 18 inches apart. Growing up to 32 inches tall, this is a mid garden to back garden plant. Its upright habit will pair wonderfully with lower growing sun loving annuals in your landscape or large container garden. Be prepared to reach for this lovely purple flower year after year for your full sun gardening needs.
