Botanical definition?
Is there a botanical expression or definition to distinguish between,
perennials which die back each year, but regenerate from the old rootstock, and perennials which do not die back, eg cactus, succulents, trees, etc.? -- ned |

Some old (19th century) material on the topic http://www.malvaceae.info/Literature...B/Chap1-1.html I think the term you're looking for is herbaceous perennial. -- Stewart Robert Hinsley |

I found it interesting. It says a lot that I'm in tune with the 19th century! ;-)) -- ned |

The point which I wished Bentham to make for me was that the division of plants into these groups isn't cut and dried. Elsewhere you'll find people talking about shrublets and treelets, and herbaceous perennials divided into bulbous, cormous and tuberous (collectively "bulbs"), rhizomatous, stoloniferous, etc., perennials. -- Stewart Robert Hinsley |

'Just thought that the 'splitters' might have come up with a twee definition. But I'm happy with the concept that while the leaves and stems of a 'herbaceous perennial' may die back seasonally, its rootstock can last several years.

The question was asked ".......Is there a botanical expression or
definition to distinguish between, perennials which die back each year, but regenerate from the old rootstock, and perennials which do not die back, e.g. cactus, succulents, trees, etc.? .............." Interesting, The term herbaceous perennial tends to be used to cover both plants that die back for the winter such as Phlox, Michaelmas daises etc as well as such plants as Pinks,Wallflowers such as Bowles Mauve etc which hold their leaves all year round. Checking back through my old "Bible" the describe Herbaceous as A word which means herb like growth. It is applied to plants which bear stems which die down to the ground annually. Whilst Garden pinks are described as "Garden plants". -- David Hill Abacus nurseries www.abacus-nurseries.co.uk |

There are definitions for plants where the growth point during the dormant season is below, at or above soil level, which is what is being asked for, but I now forget them and they are rarely used. There is also the problem that many plants will behave in different fashions according to conditions - e.g. many plants will grow from their stems after a mild winter but from their roots after a hard one.
