PERENNIALS<br />
Claytonia virginica L.<br />
Virginia spring beauty, spring beauty, claytonie<br />
per. (bulb) -21° to -15° C Apr-May 10-15 cm NP<br />
Value for honey and pollen: valuable only because they are so early flowering when<br />
little else is in bloom 72 .<br />
Notes: .pink flowers, useful ground cover in part shade; moist soil; native to e.<br />
Canada 12 ; rich woods, thickets, and clearings, sw. Que., and w. and s. N.E. to s. Ont.<br />
and beyond Can. limits 23 .<br />
Clematis L.<br />
clematis, virgin's bower, leather flower, vase vine, clematite<br />
per. vine (MP<br />
Value for honey and pollen: only some offer N, but all are sources of P except in the<br />
case of some of the garden hybrids (e.g. x Jackmanii T. Moore which is useless for<br />
bees 35); C. virginiana L. (white clematis, woodbine, virgin's bower, devil's-darningneedle,<br />
herbe aux gueux) is not often seen in gardens, but produces abundant N 72 and<br />
is common in N.S., Que., Man. and locally in other provinces.<br />
Notes: The clematis flower has no true petals, but the brilliantly coloured sepals serve<br />
instead. This large group of useful vines are not as widely appreciated in N. America as<br />
they are in Europe where many of the smaller flowered spp. (unknown in most N.<br />
American gardens) are popular. Many clematis spp. are probably popular with<br />
honeybees, but there are few records indicating the value of particular spp. to<br />
beekeepers.<br />
Clematis armandii Franch.<br />
Armand clematis, clematite du Pere Armand<br />
per. -15° to -12° C May-June vine to 12 m NP<br />
Value for honey: observed to "hum" with bees.<br />
Notes: white fragrant flowers in showy panicles; blooms on previous year's wood 95 ;<br />
thrives in coastal B.C., but is too tender in most other parts of Canada.<br />
Clematis ligustictfolia Nutt.<br />
western virgin's bower, western white clematis<br />
per. -23° to -21° C Aug-Sep vine to 6 m NP<br />
Value for honey: a 3.6 tonne surplus reported from wild clematis (likely C.<br />
ligusticifolia) in B.C. in the 1930's 72 ; N sugar concentration 48%, but bees observed to<br />
obtain very little N from each blossom 94.<br />
Notes: white flowers in plumose heads; climbing over bushes in Man. to B.C., S.<br />
beyond Can. range 23 .<br />
Clematis montana Buch.-Ham. ex DC.<br />
anemone clematis, clematite des montagnes<br />
