Clematis Allanah
Very large, deep crimson, velvet flowers with very deep red, almost black anthers are borne at the tips of the stems. A group 3 clematis. Group 3 clematis includes the varieties that start their flowering after mid-summer and continue well into Autumn or even into early winter, if it's mild. So-called herbaceous clematis are also included in this group. These varieties like to be cut back hard in late winter. Stems are pruned just above healthy pairs of buds about 12 - 18 inches above the ground. Group 3 clematis can be pruned at the start of winter as the old stems are of no further use. However, this practice is only advisable in very sheltered positions. Mild winter spells can produce active shoots which can then be hit by frosts.
