Petchoa (Petchoa spp.)

Petchoa Plant Features

Petchoas are beautiful sun-loving annual flowers for sun. They're relatively new plants on the market, so a lot of gardeners haven't heard of them before. Grow petchoas and you can be a trend setter! These flowers are gaining popularity because they're easy to grow and offer beautiful petunia-like flowers in a stunning range of colors. Happily, they don't suffer from some of the problems that their old-fashioned cousins do.

Most petchoa varieties have a mounding or trailing shape, making them versatile and perfect for both container gardens and landscaping. In pots, use them as lovely filler plants to add color and texture, or as spiller plants, to cascade over the side of the container. You can also use them to perfect effect in hanging baskets.

Petchoa Growing Instructions

Grow petchoas in full sun (at least six to eight hours of direct light a day). They can tolerate some partial shade, but they won't bloom as well and are more likely to get lanky, unattractive stems without enough sun. Like most flowering annuals (including petunias and calibrachoas, to which they're related), petchoas prefer moist, well-drained soil rich in organic matter if you grow them in gardens. In containers, choose a potting mix designed for use in pots. Water them regularly to keep them from wilting -- but take care not to overwater. The soil should never stay wet or soggy, otherwise the roots could rot. 

Fertilize petchoas regularly during the growing season or make it easy on yourself and use a slow-release fertilizer at planting time. Slow-release fertilizers deliver a little bit of nutrients to the soil each time you water and you only need to apply them once a season. 

You typically don't need to worry about pinching or pruning petchoas to keep them pretty, through you can if you'd like to encourage more compact growth. 

Note: Petchoas aren't intended for human or animal consumption.
