I have to add this one here...it's the most astounding (perennial acting) tulip! I do absolutely nothing for it; in fact, I didn't even plant it, a squirrel brought it over from mom's garden area.
That critter must have known the absolute best spot to put it, because it flowers year after year, without digging it up or anything. Each year it increases its number of blooms as well. Last year there were four, this year there's seven! The blooms usually last a really long time, too; sometimes for months.

Tam, have you ever visited Dunfee Plumtickled Junction? They have plants for sale once the weather warms....and they provide lunch, too.
