Yes, plant them now! Species of true lily, Lilium, are poisonous to cats, although unless grown indoors with bored housebound cats you should have no worries. The list of commonly grown outdoor ornamental plants that are toxic to some degree to pets (and kids/humans) is really rather staggering but the incidence of poisoning to either tends to be extremely low. In most cases, one would need to consume quite large quantities to have anything more than an upset stomach. Zephyranthes are related to amaryllis, in an entirely different plant family from lilies, and should pose minimal risk. I've gardened with an assortment of pets all my life and other than some puppy-aged chewing, they have never seemed to find the need to graze on anything planted outdoors other than some lawn or weed grasses.

I use iScape for playing. :) I’m using the free version on my iPad, so the choices are limited to adding 10 things (plants, hardscape, etc). If you pay, you can get more choices. I’m not a pro, so the basics work for what I want to do. I used it for one of my new beds recently, and it helped me a lot with getting a color/texture/size visual. Anyway, just playing around with your yard ... not suggesting specific plants, as I don’t know your conditions. The flowering vine could be on a structure not touching the utility boxes, but close enough to hide them somewhat. But like Patricia said, check with your utility company. In my town, they try to read them from the street now, if possible — but still walk neighborhoods that have the boxes in the backs/sides of homes. At my last house, I planted a hyacinth bean vine right on the pole from the ground, and it was perfect. It wasn’t too full, and covered just enough without hiding the display. For when budget allows, I think seating would be nice.

I was going to mention exactly what Toby did. Hottest month of the year, Multnomah Falls won't likely be 'falling' as spectacularly as usual. The trip down from Seattle will be at least 4 hours-if you go the coast route plan on it being at least 6 hours then another hour plus into Portland. Southern Oregon and Crater Lake would not fit into your itinerary, just too far to go, plus at that time of the year the heat is brutal! Seattle traffic is crummy and no parking, but it's a great place to visit. My Aunt recently moved to Gig Harbor and loves it, I was planning to visit in May but my reason for a trip to Seattle was cancelled, so I'll be postponing that, but I hear it's beautiful. IMHO I'd stick to the Seattle/NW Washington/SW Canada area. You'll definitely want a rest between road trips! I'd suggest a planned visit to the Tacoma Museum of Glass. Dale Chihuly usually has exhibits there-oh and the Chilhuly Gardens. I missed that my last trip up there but it's definitely on my next list. August would be a good time to stay in that area-the weather should be perfect.

what she said in toto ... but here is my thought process ... i found the real name ... and looked up images ... such as here: https://duckduckgo.com/?t=ffcm&q=Hydrangea+Hydrangea+paniculata+%27Jane%27&iax=images&ia=images and then seeing that though dwarf.. it still can be a 3 or 4 foot plant ... or larger .... i would free it to mother earth ... unless .... the goal of the process is to learn about growing shrubs in pots ... with all it attendant repotting and root pruning probably every year.. if you figure out how to grow it well ... too many peeps see that a plant is a dwarf.. and think its going to remain a small plant ... all dwarf means is that it has a reduced annual growth rate.. as compared to its monster cousins ... but.. over the years.. even at the slower rate.. it can get to be a large plant ... and most large plants need a large root mass to flourish .. and therein lies the limitation of a pot ... ken
