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

2026 Fall Symposium Logo

This low-elevations region of Texas extends inland from the barrier islands, about 60 or so miles, and stretches from Brownsville to Louisiana. In total, it covers about 9.5 million acres, with a high point of 150 feet in elevation. More than 1000 species of plants can be found in this region. On the southern end, species more common in Mexico (such as Sabal mexicana) and Central America occur.

The barrier islands provide us with dune systems, and clay flats to the inland side, which have species found in these areas alone. Many plants here, such as Ipomoea pes-caprae (beach morning glory), can be found throughout tropical regions of the globe. I’ve encountered the same species on the beaches of Guam.

Once inland, vast marshes and wet prairies occur. Occasionally, oak (Quercus fusiformis) groves can be found. Common grasses include species of Bothriochloa, Paspalum, and Sporobolus; eastern gamagrass (Tripsacum dactyloides); and switchgrass (Panicum species). Many rivers and creeks cut through the Gulf Prairies, and along these riparian areas various species of trees, Sabal minor, and other plants adapted to clay soils can be found. Due to overgrazing, farming, and fire suppression, woody species such as mesquite (Prosopis glandulosa) and huisache (Acacia farnesiana), and invasive species such as chinaberry (Melia azedarach), Brazilian pepper (Schinus terebinthifolius), and Chinese tallow (Sapium sebiferum) have increased and displaced our native flora.
