We will be rolling out several small fixes mid-day today (Jan 29.) We do not anticipate any disruptions or problems, but f you spot any unexpected issues after 12 noon (PST), please report them in the designated thread in the DG Site Updates forum.
Good reference for perennials. Color, flowering time, height, spacing, sun/shade needs, hardiness, propogation methods and rarity are given for over 3,000 plants. Although not heavy on pictures, the ones given clearly show a mature plant, not just the flower.
