  • Patent number: 4168002
    Abstract: A carrier card integrating a group of separable blister packages containing seeds of different kinds or varieties having compatible properties, making it feasible to plant these seeds at the same season in a common ground area. The card is divided by a transverse perforation line into an upper display section on whose face is pictured the compatible plants produced by the packaged seeds, and a lower section sub-divided by longitudinal perforation lines into a group of strips. Each strip has adhered to its face a clear plastic bubble backed by a plastic base to create a hermetically-sealed blister package within which is housed a charge of pelleted seeds, the seeds in the packages being of different color to facilitate discrimination therebetween. The bubbles are shaped to define at their lower end a tapered spout which can be snipped off to permit the housed seeds to be dispersed. Each strip is labelled to identify the seed plant, the strip being usable as a ground marker for the plant.

  • Patent number: 4080755
    Abstract: A plant marker which serves not only to facilitate the implant of seeds at the proper depth, but also functioning to encourage the upward growth of the seedlings. The marker is constituted by a tab which is insertable in soil to a depth determined by a ground line which divides the front face of the tab into a short lower section and a longer upper section. Mounted across the lower section is a piece of bio-degradable tape encapsulating the seeds to be planted. The upper section is coated with a light-reflecting layer whereby when the marker is buried in soil, the resultant seedlings will intercept the rays of the sun advancing toward the upper section and will be directly exposed to incident rays on one side, the other side of the seedlings being exposed to reflected radiation, whereby the seedlings will not elongate and incline toward the source of the rays but will grow upwardly.
