Herbaceous Plant Materials

Herbaceous Plant ID Lab


Plant identification is a useful tool to determine the cultural requirements and desirable attributes of the plants around you. By familiarizing yourself with a small group of plants, it will be easy to increase your knowledge about other plant species, their use, and their culture.

Herbaceous is the term generally given to any plant that does not form a persistent woody stem. Herbaceous plants are often known for their attractive flowers or foliage. Genetics, climate, cold-hardiness, and length of daylight are among some of the factors that determine the classification of herbaceous plants.

Herbaceous plants may be classified on the basis of physiological growth cycles as:

Annual: A plant that completes its life cycle of seed germination, vegetative growth, flower set, and seed production in one growing season.

Biennial: A plant that completes its life cycle in two growing seasons. (i.e. leaves are formed the first season followed in the second season by flower set and seed production).

Perennial: A plant that perpetuates itself for long periods of time usually growing from modified underground stems; attain a long life span.

Hardiness Zones are catagorized by their average annual minimum temperatures. Each zone is a range of 10 F. Plants are limited to successful growth by the lowest temperature at which they can survive.

Information I gleaned from the USDA plant database: plants.usda.gov/index.html Enter Scientific Name as Talinum
Talinum Adans. - gives you all varieties and maps of where they are present - click on a map to get information for that variety
- Talinum calycinum or parviflorum - most common varieties present in the central states from Texas to Minnesota/Nebraska.
- all varieties native to U.S.
Some common names:
Jewels of Opar (not common but a cool name, no?)
- Herbaceous Perennial, Shrub or Subshrub
- Native to the United States
- Talinum calycinum had a botanical illustration which showed a rhizhome (like an iris)
- Purslane family like Lewisia and Portulaca
- I doubt it is invasive. As a...

DALY: Use care when planting around septic drainfields  — Gwinnettdailypost.com
Shallow rooted annual and perennial herbaceous plants can be planted closer to the drain fields since they do not have invasive roots. Turfgrass can be grown over the drain field and is beneficial since it helps hold the soil in place.
