Arabis petiolaris

Ray and his Bosom Brother, Crumby, have always wanted to have some Arabis petiolaris at the CB.  So for many moons, every time a member of the Brotherhood espied some Arabis with fruit,he collected a little. Then, they would bring the fruits back to the CB and sow the mustard seed on the site of the old septic field.  Why there?  Easy that, the old septic field has sand to a depth of a couple of feet.  Arabis likes sand.

At last the Arabis has took.  We have maybe a dozen plants seeding out at this actual nonce. Here's a dramatic look at the siliques, the plants most noteworthy feature.
