What are the most unobtrusive labels for the garden?
Any of the metal or slate labels, as above. Black plastic labels are less obtrusive than white or coloured plastic, particularly where they will be partially hidden among foliage. These are available as pot labels in 10cm or 20cm lengths, as T-labels or angled-head bed labels, so there is a range to suit every situation. Popular alternatives are black scratch-on labels, engraved with a scriber which reveals the white underneath the black surface. These are available as stick-in or tie-on labels.
