Teaser Moisture-loving Iris has fragrant blue-violet flowers with falls crested in yellow and white.

Iris virginica var. shrevei, commonly known as Shreve's iris or Virginia iris, is a beautiful and hardy native iris variety found in the southeastern United States.

Foliage: This iris forms dense clumps of stiff, sword-shaped leaves that typically grow 12-24 inches tall.

Flowers: The showy, three-petaled flowers of Shreve's iris bloom in late spring to early summer. The upright "standards" and hanging "falls" come in shades of deep blue, purple, and violet, often with white or yellow accents.

Growth Habit: Iris virginica var. shrevei is a rhizomatous perennial that spreads slowly over time to form colonies. Mature clumps can reach 18-36 inches tall and wide.

Cultural Needs: This iris variety prefers full sun to partial shade and consistently moist, acidic to neutral soils. It is more tolerant of wet conditions compared to many other iris species.

Native Habitat: Iris virginica var. shrevei is native to wetland habitats, such as swamps, marshes, and stream banks, across the southeastern United States, including areas from Virginia to Louisiana.

Landscape Use: Shreve's iris makes an excellent choice for rain gardens, bog gardens, pond/stream edges, and other moisture-retentive areas in the landscape. It also works well in perennial borders and naturalized plantings.

Wildlife Value: The nectar-rich flowers of Shreve's iris attract pollinators like bees and butterflies. The foliage and seeds also provide food and shelter for various wildlife species.

Overall, Iris virginica var. shrevei is a beautiful and adaptable native iris that thrives in consistently moist garden conditions. Its vibrant flowers and tolerance for wet soils make it a valuable addition to many southeastern landscape designs

Limited Availability

We try very hard to source exactly what you’d like, but sometimes growers run out of plants! While this variety is a great deal at the price shown, we know that it has limited availability. If you want the plant even if it might be more expensive, or in a different size or quantity -- after you place your order, just send us a quick note at help@northshoreplantclub.com. Then, we’ll try to get you some version of this from one of our growers. And if we can’t get it from anywhere, of course, we’ll send a refund!


Field-Grown vs. Greenhouse-Grown Plants

Plants which are well-adapted to our local climate are most often field-grown (outside). Field-grown plants are generally cheaper and have the advantage of already somewhat acclimated to our cold winters, but that means they’re not artificially far along in the spring and tend to bloom at the normal time in our area.

Spring annuals and tender perennials are typically grown in Greenhouses so they can be ready and luxurious exactly when customers want them. Some perennials are also “forced” into early bloom in greenhouses. In May, there can be a very big difference between field-grown and greenhouse-grown plants of the same type. The latter typically look good right away (so they’re a great choice where that’s important), but we typically pay a premium for it.

About Ordering From The Plant Club

To secure the best prices for club members and make sure we know the current plants available from each nursery, we take orders only a couple of times a month.

The next order is coming up soon. Here's a link to our ordering calendar. Shoot us an email at help@northshoreplantclub.com, and we'll be happy to talk about plants or let you know when it's time to buy them!


No Pricing or Availability Right Now

We order from a rotating cast of the best nurseries in the Great Lakes region. It looks like we've offered this plant in the past, but the nurseries we're working with this week don't appear to have it in stock at the moment.

Our goal is to bring as many plants together under "one roof" as possible, so we'll try hard to make it available again in the future!
