Known Issues Sharp drainage a must.  Susceptible to root rot is it is watered too much.
Planting Instructions Plant in sandy, gritty soil with the crowns high to help prevent root rot.

If planting from seed, the seeds do need to be frozen at some point in order for them to grow.  It is suggested that an entire seed packet be planted in one hole 3/8” below surface in a pot (let it winterize).  Leave in the pot for an entire season.  The next year, the sprouts can be separated and planted individually 8” – 12” apart.

What an great blog! I think this is exactly what a novice (and several 'not-so-novice') gardener is looking for. I garden in the tropics but I have a major soft corner for temperate (and temperamental) plants. So this kind of information is invaluable to me.
Thanks for stopping by The Urban Gardener (and choosing to Follow it).

Sunita - thanks for the praise. I have so many plants and so little time . . .

SQ - I'm planning on clumps of lewisia around my daylilies. I thinking a rainbow of color peaking out around the green grass would be perfect.

What a useful blog. I have the green thumb but not much time for gardening. Sigh! Keep this up. I enjoy looking at pretty and growing stuff. Closer to nature and the earth.
