Standing cypress

If you like hummingbirds you will like Standing Cypress. Its profusion of red, inch-long trumpets are made to order for hummers.

Standing Cypress or Ipomopsis rubra is very dependable in the sandy Cross Timbers soil where I live. It’s a biennial. It produces a ferny rosette the first year, followed by a flowerspike the second year.

I’ve generally grown it from seed, although you can transplant the rosettes fairly easy, as long as you dig down and get about six inches of the tap root. It likes the sun and is generally pretty drought-tolerant. At my place it seems to prefer the gravel driveway to the flowerbed where I keep trying to put it. After it goes to seed, collect them and sow wherever you want them.

The flower spikes can be anywhere from two feet tall to more than six feet in wet springs. When the spike has bloomed out, you can cut it off, and new spikes will be formed.

The relationship to hummingbirds is not a one-way street. Standing Cypress depends on the hummers for pollination. Plus the hummingbirds help control the insects that nibble the plants.

According to most sources Standing Cypress is not considered deer resistant, but I’ve never seen the deer show any interest in it at all.

About the Region

Fall Symposium 2025 Logo - Teach for the Future

Salado, the location of our Fall 2025 Symposium, lies at the intersection of two ecoregions: the Edwards Plateau (Limestone Cut Plain) and Blackland Prairie (Northern Blackland Prairie).

The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our fall Symposium host chapter, the Tonkawa Chapter, includes both of these ecoregions.
