Ruellia humilis (Wild Petunia) [15 Seeds]


Germination Information: I recommend these seeds for experienced seed-starters only, because they require some patience. The easiest approach is to sow them in fall to late winter, just barely covered with growing medium. Set them outdoors in a spot protected from mice so they can get a chilling period and then germinate when conditions are right in spring. (The winter-sowing technique can work very well with these seeds.)

If you sow after February, give the pot an artificial chilling period of around 2 months.

Once you get wild petunia to flower in your garden, it’s likely to self-sow (possibly to the point of being considered aggressive in the Deep South). When the seedpods snap open, they can fling the seeds quite a distance, so you may find seedlings popping up in surprising places.

Note that this information will not appear on the seed packet you receive.

Wild petunia (Ruellia humilis), also known as fringeleaf wild petunia or hairy petunia, is a perennial that grows in 1- to 2-foot-tall clumps, with lavender-purple flowers from early or midsummer into early fall. The trumpet-shaped blooms, which open in the morning and usually close in the afternoon, are appealing to hummingbirds, butterflies, and other pollinators. Native to parts of the eastern and central US, wild petunia is naturally well suited to hot, dry sites but also grows well in average, full-sun to light-shade garden conditions. Perennial; Zones 4 to 8.

Collected in late October 2023. At least 15 seeds. Unknown ecotype. Shipping to US addresses only.
