Re: Landscaping Irises

Hi Everyone!

Apropos of the recent discussion on this List with regard to the landscape
character and use of irises, there is an article in the current (December,
1997) issue of Horticulture titled "Setting the Standard" which advocates
the establishment of uniform standards for classification of perennials and
advances some suggestions for moving in that direction by proposing
language for standardized descriptions of care requirements, siting
considerations and growth characteristics of perennial plants.The proposed
care categories, which are most pertinent to our recent dialogue, are as

Landscape Perennials (LP) - Quickly and inexpensively produced plants,
which, when properly sited and established, will persist for 5 to 10 years
with minimal, routine care. They should provide long-season interest from
texture, form or color with at least three weeks of interest to the general
public. Plants for public places.

Garden Perennials (GP) - Grow slowly or are somewhat costly to produce.
They often need special care or frequent attention to perform well in the
landscape. Plants for private gardens or display gardens tended by

Connoisseur Perennials (CP) - Difficult or time consuming to grow and
costly to purchase. Often require precise siting and continuous cultural
care. Plants for the experienced grower, the plant collector or special
types of gardens.

How would (or could) you categorize the various classes of iris according
to this scheme?

(Attention, Graham Spencer: There is also an extensive article on hardy
Geraniums in this same issue of Horticulture. It is noted that there is no
known North American source for Geranium pratense 'Plenum Album" mentioned
therein. Does this represent a marketing opportunity for Croftway Gardens?)
