PERENNIALS<br />

Medicago falcata L. 51<br />

(syn. Medicago falcata (L.) Mill.; M. intermedia Schuh.; M. silvestris Fries; M. sativa<br />

L. var. falcata (L.) DM; M. sativa L. ssp. falcata (L.) Arcang; M. subfalcata Sinsk.; M.<br />

sativa ssp. vicosa (Reichb.) G.R. Gunn)<br />

lucerne, Siberian yellow flowered alfalfa, sickle medic, yellow lucerne, luzeme jaune,<br />

luzeme sauv age<br />

per. very hardy cvs. available May-Aug NP<br />

Value for honey: HP1/2 17 .<br />

Notes: was considered as a candidate for roadside planting in B.C. in the past 73 ;<br />

roadsides and waste land, in local areas, Mass. to Man., S. to Mich. and beyond Can.<br />

limits 23 .<br />

Medicago sativa L.<br />

alfalfa, lucerne, lentine, sainfoin, grand trefle<br />

per. hardiness dependent on cv. May-Sep 60-100 cm NP<br />

Value for honey: HP5 16 ; H yield 45-163 kg/colony/season 17 ; at a rate of 4 colonies/ha,<br />

22 kg of H stored, but a rate of 12 colonies/ha gave little or no surplus 54 ; N sugar<br />

concentration 15-64% 17 ; alfalfa does not yield well under all conditions, and vigorous<br />

growth promoted by very wet springs (or irrigation) followed by hot dry conditions,<br />

gives very good to excellent yields ' 4 (for instance in the Interior of B.C.); seldom<br />

yields in humid weather, and therefore is an undependable source in the Maritimes 54 ;<br />

generally conditions that favour seed production favour N secretion 17 .54 ; N secretion is<br />

severely reduced by pests on this crop'''.<br />

An increase in alfalfa and a decrease in alsike and sweet clover acreage in Ont.<br />

in recent years, has resulted in lower average H production in that province 88 .<br />

Notes: most important legume grown in Canada and is cultivated in all provinces;<br />

important to grow the cvs. recommended for the particular area; low tolerance for poor<br />

drainage.<br />

Blossoms open from base to tip in one week and each floret remains open for<br />

about a week 17 .54 . More or less naturalized or persistent along roadsides, in old fields<br />

and waste areas 23 . See Table 18.<br />

Melissa officinalis L.<br />

lemon balm, bee balm, melisse citronelle, piment des abeilles<br />

per. -29° to -23° C 60 cm NP<br />

Value for honey and pollen: limited value for N and P 35 . Once commonly used to rub<br />

on the insides of bait hives to help attract swarms'. Also thought to ward off stings if<br />

rubbed between the hands before working with bees 3s<br />

Notes: common garden ornamental; needs shearing during the summer to keep it neat;<br />

leaves can be used to spice beverages; naturalized in e. USA; roadsides, open woods<br />

and waste land, escaped from cultivation, local, N.E. and S. and W. chiefly beyond<br />

Can. range 23 .<br />

a The author noted a similar herb cultivated in East Africa for the same purpose.
