Hollyhock Germination Time - Knowledgebase Question

Allentown, PA
Question by caroleann0

I started hollyhock seeds (1999 Burpee) under lights. 3 came up. The rest did not. Do different colors have different germination times? All are growing under the same conditions.They were all planted about two weeks ago.

Hollyhocks do not usually take particularly long to germinate when compared to other perennials; depending of course on soil temperature I would think about two weeks would be an average time at 65 degrees which is a bit cooler than many seeds require. If you have had them under lights it is possible it has been too warm, especially if you have had them covered with plastic to maintain humidity. With any luck you will find the rest germinate within the week -- it is possible the early three were planted more shallowly or washed about a bit when you watered or something of the like. In my experience some of the more unusual colors do seem to be a little bit slower than the others.
