The only colorful bulbs are crocuses and a few Siberian squill, no open flowers yet, but you can see the colors in the closed blossoms. The daffodils don't seem to have even emerged yet. There's a pansy or two in bloom. Lots of other stuff going on  corn salad has come back; sorrel, thyme, and sage have leafed out. Brambles have leaf buds, some (blackberries) starting to break. Celeriac and just a couple of kale and chard plants seem to have made it through the winter.

Just a common old garden spider.....nothing to worry about and nothing to do with whatever may be ailing your holly (not a Japanese holly, btw). Garden spiders are good things and should be encouraged. FWIW, hollies can be cut back hard and they will backbud or produce new growth from bare stems. Your plants look perfectly healthy otherwise and with no sign of insect or disease issues so why they are so leggy and sparse now is most likely due to cultural conditions....lack of water at some point, possible cold damage at some point or issues with the root ball when planted.

Looks like large pavers. We live in wet winter country - PNW so moss etc is a routine thing here. We use the product Wet and Forget on our smaller pavers which works on moss & grime pretty well. Not all moss is green - it’s black mold looking too. Wet & Forget comes in concentrate or a sprayer container. Needs to be put down when pavers are dry & be able to stay wet for @ hour - so no spraying in sun or heat. Rain comes & washes black away & moss dies so it’s not immediate result but is seen working after the first rain. Not sure how successful this would be in less rainy climate. We buy it at Costco - product is popular here. We did pressure wash our pavers once using a round attachment that gives a much softer wash than the angled hard spray of the angled spray point of pressure washing. We were afraid the pressure washer would lift all the sand filler between the paver joints. ETA: we’ve never sealed our pavers but it is done by some. Need to clean first & I think it’s not permanent so must be redone every few years.

Your new June sure is loving it's new home! Heart and Soul looks good, too. I wonder if your teaspoons will have more elongated leaves being in more sun than the rounder ones I think happen in more shade? I'm not surprised to see the whites burning on High Society. It will be interesting to see what acclimates to more sun next year. I have one in sun that burns every year, and it just dawned on me to move it, lol. Ironically, it's Sun Power. It looks great in spring, which I suppose is why I've left it there, but it can't take the harsh sun we have by summer.
