Propagation Methods for Herbaceous Perennials--T
A | B | C | D | E | F | G | H | I, J, K | L | M | N, O | P | R | S | T | U,V,W, X,Y,Z
The following table contains temperate and sub-tropical (to USDA zone 9) herbaceous genera and species. Some may be quite rare and only found on a continent or country such as Australia or South Africa. Due to variations in references, some may contain more than one comment or time period for a method.
| Methods of Propagation: | |
| S = seed | LC = leaf cutting |
| SC = stem cutting | L = layering |
| RC = root cutting | TC = tissue culture or micropropagation |
| D = division |
This table is an updated and expanded version of the printed version which can be found in the NRAES book by Dr. Leonard Perry, Herbaceous Perennial Production. Appreciation is expressed to Andrea Luchini, graduate assistant, for most of this update.
