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.
Yes, the first picture (of the second set) is a Gardenia but it is more likely to be Chuck Hayes, Veitchii, or Mystery based on the leaf shape. It also had a whitefly problem last summer judging by the sooty mold on the lower leaves. You may want to use a systemic insecticide on it once the weather warms up.
The plants in the second picture are Carissa (Chinese) Holly and some kind of deciduous Magnolia like Magnolia stellata (Star Magnolia) or possibly Ann or Jane.
