so you guys are absolutely sure.. this thing could not have had some dead branches?? obviously the tree guy left the live parts.. suggesting to me.. there were some actual dead branches ... now i might not trust with plant lore.. is the real estate seller.. crikey ... they may have thought crabgrass was an exotic looking plant.. lol .. you can get the name of just about anything in this forum ... so lets not rely on strangers outside their specialty.. to tell you about what is in your garden ... and.. BTW... who could have damaged this plant severely .. is the lawn service ... you need to remove a 3 to 5 foot circle of grass... and add a mulch ring.. to keep the nut with the lawnmower and weedwhip away from it .. weedwhips damage more plants than tree guys.. and real estate peeps.. and it could have happened with the prior owner ... i dont think you really know how long the dead parts were dead.. now do you??? ken

The first is a bulb (technically a corm)...Colchicum autumnale. I don't recall the name of #2 at the moment. The third is Fuchsia magellanica. I don't know #4

" Looks like they have made over-wintering basal foliage, as though saying "It's time to clear away the flowering stems". " At this time of year Rudbeckia Laciniata should look all lush, green, and yellow (flowers). It looks like plants are drying up much too early also in the OP's (warming up) climate. Plants are definitely not created by Nature to have their blossoms "cleared away" as soon as they start flowering.
