I echo the advice to plant winter growers now, but don't water yet. Pot them up in dry mix, and set someplace warm and out of the rain, where you will see them. Especially in cooler Portland, you never know how early they will decide to grow. If they sit in a paper bag or on the shelf, start to sprout when they are ready, and you don't get around to potting them up, they will die. If they are in a pot and sprout, all you have to do is water. Pot up, and water, summer growers ASAP. Oxalis don't keep well past their growing date. They grow extremely well in sand in foam beverage cups you recycle from the office. I grow lots of them in foam 20 and 32 ounce / 600-950ml cups. Remember that the flowers don't open unless sun shines on them. Leo Martin Zone 9? Phoenix Arizona USA
