I got some bad news recently. I picked up a new edition of “Plant Invaders of Mid-Atlantic Natural Areas” and found that one of my favorite bulbs, Hyacinthoides hispanica, or Spanish Bluebells, is a new entry, its invasive qualities manifesting in my area.

Some invasive plants are sneaky. They pop up in one’s garden without explanation or obvious origin and force gardeners to take action on the spot, lest they be forgotten and allowed to grow and spread. Some of the sneakiest are the Bush Honeysuckles, several species of Lonicera with Eurasian origins.

Confession is said to be good for the soul, so here it goes: I have, while standing in someone’s garden, wimped out on telling them their Butterfly Bush (Buddleia davidii) is invasive.
