Asclepias tuberosa -- Perennial Plant of 2017
And many other new picks at Arrowhead!


We've just added a bunch of new plants to the online catalog, including Asclepias tuberosa, voted 'perennial plant of 2017' by the Perennial Plant Association.

You can check out our complete listing over on our shopping cart. There's guaranteed to be something new and interesting you don't have yet! Here's a little picture-tour of some of what's new for this fall:

Asclepias tuberosa will get quite large in the garden

Voted perennial plant of 2017 by the PPA


I expect a flood of new coverage on this perennial in gardening and horticulture magazines this year. Place an order soon if you want to ensure you can get one!

A. tuberosa closeup

A. tuberosa is a must have if your tastes run to the bright colors. Tops out at about 18 inches, with masses of warm-colored flowers in late Summer from orange, orange-red to buttery yellow. As we said, one of the favorite food plants of the Monarch butterfly -- if you grow it, the butterflies will come. Like any milkweed, A. tuberosa is not particularly hard to grow. We recommend good drainage and full sun, but a little bit of shade won't kill it either.

Dracocephalum austriacum in our trial beds

Dracocephalum austriacum is a very rare species growing in rocky habitats. Foot high with scapes whorled in blue violet dragonheads. The general area of distribution includes alpine ranges from central to south-eastern Europe, down to Turkey and Greece where it is considered an endangered species.

Also known as Nordic Dragonhead, grows between 16" to 24" tall, and forms neat bushlets of attractive foliage. Strikingly blue flowers and very tidy, easy to take care of. Hardy up to zone 5. Can't go wrong with this one.

Lindera benzoin: (click to view on our store)



Lindera benzoin

Just like the Asclepias, we have another wonderful butterfly plant here in L. benzoin. Commonly called Spicebush, this is the main food plant of the Spicebush Swallowtail Butterfly (some pictures are here on the blog). The promethea silkmoth will also flock (literally) to L. benzoin. Wonderfully fragrant yellow flowers that open early in spring to welcome the butterflies, before even having fully leafed out, and in autumn the Spicebush produces eye catching scarlet berries. Easily growable across zones 4 to 9.

The above caterpillars are those of the Spicebush Swallowtail Butterfly. These caterpillars absolutely love to eat Lindera benzoin, as if it wasn't a cool enough shrub already!

Origanum sipyleum
Collected in the Sultan Dagh mountains (Turkey) at 2000m, with cushions of bluish aromatic leaves and sprays of semi-pendant greenish bracts that encase the pale, long-tubed flowers.

Speaking of which, don't forget to check out our BULK woodland wildflowers this upcoming fall.
