Clematis (Virgin’s Bower)
The large-flowered Clematis are the most expensive vines we have. So slowly do they propagate from cuttings that the price remains high from year to year. The cheapest way to obtain them is to raise them from seed and, though this is a more or less uncertain method, the expense is so slight compared to the purchase of plants that where many are required it is worth repeated efforts. Plant the seeds in flats in the house either in fall or spring. Cover an eighth of an inch and press the soil down firmly, keeping moist and warm. They germinate in from six weeks to a year; for this reason fall planting is desirable, as the soil may more easily be kept in the right condition. When the plants are large enough to handle, pot off into small pots and plunge in the sand-box, if the weather is warm enough, or in a sunny window if cold. Winter in a frost-proof cellar the first winter, putting them in the open ground where they are to remain till the following spring. The plants will give a few blossoms the second season, enough to show the variety, and the next year may be expected to bloom freely. Plants raised from seed are more likely to bloom and do well than those from cuttings.
Clematis paniculata comes more freely from seed than the Jackmanni strains, and should be largely grown, as it is one of our loveliest vines and blooms when most others have ceased. Clematis flammula self-sows and established little plants are continually coming up in unexpected places, which may be removed to any desired position, as this variety does not in the least mind being disturbed. All Clematis are benefited by winter protection, and such varieties as Ramona and other spring bloomers should have the tops protected with sacking or old carpet. Mrs. Edward Andre dies to the ground in the winter, but should be well protected around the roots. Many growers cut back Clematis to within a few feet of the ground each fall, but where large spaces are to be covered one loses much time, as the frost usually does all the trimming necessary. The early spring bloomers from last season’s wood and cutting back in the fall simply lessen the blossom points. If it is necessary to trim for symmetry or lack of room it should be done immediately after the plants are through blooming, that they may have abundant time for new growth.
