Impatiens balsamina. - Touch-me-not. - The Double Balsam is one of the most prominent ornaments of the garden, in July and August. Old seed is considered by some to be the best, as more likely to produce double flowers. The seeds should be saved from double flowering plants only; all single flowering ones should be destroyed as soon as they appear. Most plants raised in a hot-bed do better to transplant into small pots, and shift to larger as they increase in size. Balsams thus treated, sown the first of April, will begin to flower the last of May, and may be turned into the ground in June, without checking their growth in the least. If the soil is rich and a little moist, or supplied with moisture, the plants will attain a monstrous size, and be completely covered with a profusion of flowers all the season. All the full double varieties are beautiful; the colors are crimson, scarlet, light and dark purple, rose, blush, white, etc.; some produce white and red or purple flowers on the same plant; others are variegated, or spotted with various shades of red and purple, which are decidedly the most elegant. The seed should be sown in the open ground about the middle of May; they will then flower very well for two months of the season.
