Unless you are going to take really dramatic steps (like covering the tree and heating overnight) then you'll probably have to just wait and see if the blossoms are damaged by the cold. Hopefully you have trees that are well suited to your climate, and therefore most of the time the blossoms won't be killed by frsot because the trees will bloom at an appropriate time of the season.

1 lawn grass going to seed 2 perhaps hawthorn seedling 3 ivy groundcover & Norway maple on left (both invasive in many parts of the country), rose of sharon 4 thistle if prickly, wild lettuce (Lactuca) if not 5 variegated vinca 6 don’t know what it is, but try a hand tool to scratch around and root it up before it gets larger. 7 nightshade, Solanum sp. Will seed around weedily 8 young ash tree 9 vinca 10 virginia creeper and ivy 11 young Norway maple probably (tear leaf and if sap milky, Norway) 12 ash tree seedling 13 P.I. A strong mix of glysophate herbicide used on whole area, reapplied when it has resprouted, and then followed by corrugated cardboard covered by mulch will get rid of most of it. Reapply glysophate ASAP as any new sprouts appear through the mulch. This has the advantage of covering up the old foliage with its still-there urushiol oil and keeping other weeds from sprouting as well as keeping the PI from getting any photosynthesis going. Soak effected clothing in Biz, wash twice with regular detergent. Wash skin with alcohol, soap, alcohol, soap. It is drying to skin, but will remove all PI oil. Wipe down shoes with alcohol. I can get rash again from clothes that weren’t adequately cleaned. Microwave a bowl of oatmeal and smear that on skin when cool for the ultimate relief. 1% cortisone creme works to reduce itch as well. (It took me most of a summer to figure out that our cat was wandering into the PI and then sitting on the furniture and I was getting it all over the back of my legs from Urushiol on the furniture.) 14 Virginia creeper and some more nightshade 15 Hosta (plain green at top) but not sure of viney thing, perhaps more nightshade 16 See comment for 6 17 sedge, a grass-like plant but not grass. Some varieties are ornamental, so if you like it, leave it. 18 not sure what it is, but a weed. It has seeds with fluff attached that will drift around and reseed if you let it get that far 19 Avens - weedy type probably 20 weed, but don’t know name - has tiny pink or white flowers 21 ivy - see note for 3 22 Virginia creeper spreads more than I like in my garden even though it's native 23 wild or black cherry (Prunus) seedling 24 red maple seedling 25 garlic mustard - don’t let it go to seed as it will increase exponentially. Has short tap root, so a narrow weeder or old screwdriver may help if you aren't getting the roots out 26 dandelion 27 If it is fuzzy, it probably isn’t a violet; it somehow doesn't look quite right 28 same as 9 Vinca 29 red oak group seedling - could be red oak, black oak 30 hosta - different variety than at top of 15 31 my sympathies! A suggestion that you start saving the cartons from your folks' move or collecting cartons at the grocery store as well as newspapers. As soon as you get an area cleared, put down cardboard if it is a large area or multiple layers of newspaper, folded as needed if you are working around plants (wet it down so it stays put) and then cover immediately with mulch. This will reduce more weeds sprouting since this whole yard most probably has a huge bank of weed seeds in the soil. The least expensive way to get mulch is by the truck load if there is somewhere you can have it dumped and then wheel-barrow it to where you want it. (Some towns compost yard waste and residents can get mulch free or inexpensively as long as they pick it up.) When things are a bit under control, you can cut in a deep V edge between the lawn and the mulched areas or get some of the plastic edging and dig a slot to bury that along the edge. Once these things are done, you can decide if you want to do some planting, probably next season. Just remember where the PI used to be so that you don't get it from the dead plants and roots. PS - the cookie recipe would be more than welcome to me!

Kind of looks like Rainforest Chili a little bit. Not really sure what it is just yet but these pictures help us out a little bit more. Just be aware we may never really know. If you really like it, it does not really matter what it is. Just grow it and enjoy.

a bit of hydrocortizone blended in with moisturizer will tone down the 'burn' - after that, less is more. out to dinner means soft lighting, a light tinted moisturizer is ok, but don't try and 'hide' it, you just risk irritating your skin.
