Valerie, Did you save the combo starter mix with the ungerminated seeds? I was
just wondering if maybe some Castillejas might need more than a year to
germinate. I noticed a lag in outdoor germination of Aquilegia seeds up here.
It took 3 years from sowing the seed in situ before I saw the first seedling.

Hello Jane,
Last year I successfully germinated 1 out of 10 Castilleja miniata seeds
obtained from the SRGC seed exchange. �I sowed them on combo of starter
mix and grit, just covered with granite grit, gave them outdoor treatment (we
did get some days of freezing), in a tray with a vented dome over it.
�The 1 seedling was well up by May 15th. �I planted it out in the
garden about a month later when it had good root growth and some good leaf
growth, in a sunny dry bed with a Penstemon davidsonii x menziesii that likes
the same. �It was doing well, enjoying our dry summer, new leaves
growing slowly, but unfortunately the deer liked it too and nipped off most of
the top in late summer. �No sign of a resurgence in the fall and right
now it is covered in snow. �I will be interested to see if it comes up
again and is happy or if it succumbed.Sincerely,Valerie Melanson
