I love the way this peeks through the plants surrounding it: its growth pattern is sprawling, such that one planted by itself won't exceed 6" or so in height - but plant it next to taller companions, and it lifts itself to greater heights. It doesn't so much climb as support itself on its neighbors. That's why I have a hard time getting a good whole-plant photo: it's spread out, with its marvellous flowers popping out here and there.

Callirhoe involucrata
For some reason, I'm always tickled by the frumpy, ground-hugging seedlings. They're slow to grow in their first year.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.

Seed-starting details for this plant

  1. Seed from '01 JLH order. Soaked 24hr, baggy 75F (22%G)
  2. Same seed as above. Dehulled seed - more than 50% empty. Nicked/soaked. Baggy 70F (20%G, 4-14d)
  3. Seed from '04 garden. Dehulled. Baggy 70F (30%G, 5-42d) - nicked (7%G, 14d)
  4. Seed from '07 garden. Scissor-snipped husks, thereby crudely scarifying inner seed. Baggy 70F (45%G, 7-21d)
  5. Seed from '08 garden. Scissor-snipped husks. Baggy 70F (35d; 30%G, 8-21d) - dehusked/sandpapered a few - 70F (20%G, 10-22d)
  6. Seed from '09 garden. Sandpapered the husked seeds, during which a few lost their husks. Baggy 70F (27%G, 7-40d)
  7. Same seed as above. Sandpapered, baggy 70F (20%G, 6-46d, with additional scarification).
    Also var. tenuissima from HPS/MAG '13/'14 exchange. Sandpapered, baggy 70F (25%G, 5d)
  8. Same seed as above. Sandpapered, baggy 70F (17%G, 5-21d)

Seeds inside the wedge-shaped hulls are dark, kidney-shaped. Removing hulls is a slow, painful task - probably easier to sow an excess, to deal with the low germination rate. Seeds dehusked and scarified do tend to germinate within a few days.
